For the first time, the TGR-E United team will be starting the ADAC TotalEnergies Nürburgring 24 Hours race with a vehicle that is powered not by fossil fuels, but rather by climate-friendly and almost CO2-neutral synthetic fuel. This will see the team from TOYOTA GAZOO Racing Europe enter a GR Supra GT4 developed at the motor sports headquarters in Cologne and equipped with a close-to-production three liter, six-cylinder engine that has been specially optimized for motor sports use, delivering 320 kW* (430 hp).

The classic endurance race in the Eifel will now see the new technology face a truly tough task: a 24-hour, full throttle chase around the most challenging racetrack in the world. “Here at TOYOTA GAZOO Racing Europe we have already gained a lot of experience with alternative engines, but a race using synthetic fuel is a step into the unknown for us,” says Jörg Mertin, Team Manager TGR-E United. “We are always open to innovations and look forward to proving that the GR Supra GT4 can also give a good account of itself with synthetic fuel.”

Dirk Wullenweber, Project Manager of Race2efuels and Head of Marketing & Trade at LOTHER Gruppe (owner of the NORDOEL filling stations): “The biggest advantage of the Racing eFuels 98 synthetic fuel of our Race2efuels project is that it can be used immediately in any combustion engine that otherwise runs on normal super gasoline. This means that existing filling station infrastructure (such as our own NORDOEL filling stations) can be used for fuel that is mineral oil-free and practically CO2-neutral and therefore climate-friendly. The use of e-fuels is therefore a key element in the energy mix.” The fleet of combustion engine vehicles in 2030 is estimated at over 30 m vehicles in Germany alone. Synthetic fuel is indispensable if these are to be driven in a sustainable, climate-friendly way. Transferring this from the racetrack to the high street in the near future requires key political decisions to be made, such as those that have now been implemented for synthetic kerosene.

This synthetic gasoline, already REACH certified, is produced by Chemieanlagenbau Chemnitz GmbH (CAC) in collaboration with TU Bergakademie Freiberg. CAC and the technical university operate the largest pilot plant in Europe, with a theoretical production capacity of one million liters per year. Dr. Rene Stahlschmidt, Head of Sales CAC: “Using as a starting point methanol, which can be produced from CO2 and “green” hydrogen or manufactured from bio-methanol, CAC has developed this patented process, which requires no fossil resources.” Around 46,000 liters of the synthetic fuel have already been provided for test bench testing as well as fleet trials of car and motorcycle manufacturers, with the assessment thoroughly positive. Now the fuel will be put through its paces in the toughest endurance race in the world, the Nürburgring 24 Hours, with the goal of showing that it also accomplishes the toughest of tours with ease, and has high endurance limits.

The end of 2021 saw an important milestone for Chemieanlagenbau Chemnitz (CAC) - the successful commissioning of the first ferric chloride plant using proprietary technology. In this plant, the Client from Kuwait produces a saleable product, which can be used, among other things, for water treatment.

This first reference is an addition to CAC’s portfolio as one of the leading companies in the planning and construction of plants for the processing of products from chlor-alkali electrolysis. "After more than 20 years of experience in this field, we have developed a new technology with a lot of commitment as well as trust from the Client. We have created a reference, which will be the basis for follow-up projects that are already in prospect," says Jörg Engelmann, CEO of CAC.

For the Client Al Kout Industrial Projects (AIP) in Kuwait, it is also the first ferric chloride plant. Located at the site in Shuaiba on the Persian Gulf, the plant uses feedstock such as iron scrap, hydrochloric acid and chlorine gas to produce a saleable product that is used as flocculant in water treatment, but also in the etching of printed circuit boards.

“My appreciation to the entire CAC team for their support during the startup despite this global pandemic. We will surely be glad to work with CAC again”, declares Faisal Malallah, CEO of Al Kout Industrial Projects.

The annual capacity of the industrial plant at the Shuaiba site in the Persian Gulf amounts to 20,000 tons of ferric chloride (FeCl3) (based on 100%) as a 40% solution. It will only take a few retrofit measures to adjust the design of plant hydraulics for the production of 40,000 tons of FeCl3 per year if required. CAC was responsible for the preparation of the FEED package, detail engineering and supply of the main process equipment. AIP provided the bulk material supply, construction and installation of the plant.

About Al Kout Industrial Projects

More than 40 years ago, the operation of the salt and chlorine factory for the supply of chlorine to the desalination and electricity plants started. In 2000, Al-Kout Industrial Projects Group took over and expanded the plant with new machinery and equipment in order to increase capacity. AIP includes six 100%-owned subsidiaries, including a petrochemical company, a chlor-alkali electrolysis plant in the United Arab Emirates, a chemical trading and service business, water and wastewater treatment as well as sales companies. AIP has set itself the goal of becoming the market leader among suppliers of chlor-alkali and related derivatives in the Gulf States as well as in the Middle East and North Africa.

International motor vehicle manufacturers and development service providers certify drop-in capability

CAC E-Fuel

International car and motorcycle manufacturers as well as development service providers such as FEV certify that the synthetic gasoline of Chemieanlagenbau Chemnitz, CAC for short, is 100 percent compatible with existing vehicle fleets. This means that every vehicle with a gasoline engine can be driven in an environmentally friendly manner. The technology for the manufacture of this e-fuel was developed by CAC with the assistance of TU Bergakademie Freiberg, implemented as the largest trial plant in Europe in 2009 and is now ready for large-scale production – subject to political support.

The conclusion of the motor vehicle manufacturers and development service providers is based on the findings of the Closed Carbon Cycle Mobility co-operative project, C3-Mobility for short, which was completed at the end of 2021. The goal of this was to develop climate-neutral fuels for the mobility of tomorrow. CAC, thanks to years of collaboration with TU Bergakademie Freiberg, provides the technology for the gasoline synthesis used in the project. Based on methanol, which can be produced from sources such as carbon dioxide (CO2) and “green” hydrogen (H2), CAC developed a patented process that involves no fossil resources.

The large-scale test plant at TU Bergakademie Freiberg was used in the scope of the project to produce around 46,000 litres of synthetic gasoline, which was subsequently made available to car manufacturers for engine and fleet tests. This involved green methanol of biogenic origin, which was transformed into gasoline in the patented, ready-to-market process.

The findings of the project partners were thoroughly positive and were published at the concluding event of the project. The synthetic gasoline is equal to fossil gasoline in all aspects, such as material compatibility, CO2 emissions and consumption - and even holds the advantage with regard to oxidation stability and particle emissions. As E10 blend, the drop-in-capable synthetic gasoline fulfils all requirements of the DIN EN 228, it is registered according to REACH and can replace conventional fossil fuel directly or be blended with it – without the need for technical alterations to the vehicle. “The confirmation of the project partners is a great success for our technology, since climate protection needs openness regarding technology,” declares Jörg Engelmann, managing director of CAC.

“The establishment of this synthetic gasoline process is a key step towards closing carbon cycles with the aid of electrical energy. It allows regeneratively produced electricity to be stored in enduringly stable, CO2-neutral fuel, which can also be made available at times and in regions with low levels of sunshine and wind,” says Prof. Martin Gräbner, director of the Institute of Energy Process Engineering and Chemical Engineering (IEC) at TU Bergakademie Freiberg.

In addition to the main goal of reducing CO2 emissions, a further advantage of synthetically produced fuels is that e-fuels are compatible with existing car fleets (1.2 billion worldwide) as well as for agricultural and construction machinery and emergency generators. They can be supplied across the existing network of filling stations and can be both stored and transported. “We need to act quickly, because renewing the existing vehicle fleet in Germany takes around 18 years, over 20 in markets such as Greece. We therefore need a regenerative fuel that can be used in a backwards compatible manner in the existing vehicle fleets without the need for alterations,” says Dr. Norbert Alt, managing director and COO of FEV Group GmbH.

Imports from countries with favourable energy supplies will be required to make available the quantities of regeneratively produced electricity that Germany and Europe need for the energy transition in industry, transport, private households etc. Transformed into synthetic fuels or their components hydrogen and methanol, “green” electricity can also be used in great quantities in Germany and Europe.

The aviation sector is also looking for alternatives to the fossil fuel kerosene, which CAC and TU Bergakademie Freiberg are already researching together. The International Air Transport Association IATA has set milestones for the path towards climate-friendly air travel. By 2030 alternative fuels are to make up 5 % of global requirements, rising to 17 % in 2035 and around 40 % in 2040. “We are talking about enormous quantities here. The mere planning and construction of the plant required for this takes around five years. Speed is called for here, and for this we need political backing,” says Engelmann.

Synthetic fuels from water, CO2 and green electricity

This subject is generally known under the name power-to-X. The X here may be many different things: alongside gasoline, diesel, kerosene, methanol, ammonia, gas and liquid gas can also be produced from CO2 and water. All that is needed is electricity and various catalysts.

Using carbon dioxide, highly concentrated from industrial exhaust or from the air, as the starting material for the manufacture of synthetic gasoline is a promising way to apply the CAC technology and enables the use of carbon dioxide in a cycle. Using CO2 to manufacture fuel transforms an unwanted by-product into a desirable commodity. Industrial companies with high CO2 emissions would not need to release the carbon dioxide into the environment, but could instead incorporate it directly into the power generation cycle as raw material. CO2 savings can be offset with emissions certificates - if the statutory basis for this is provided. The additional hydrogen required for this is extracted from water using the electrolysis process, ideally with electricity from sustainable energy sources.

Collaboration between CAC and TU Bergakademie Freiberg

CAC and the IEC institute at Technische Universität Bergakademie Freiberg co-operate closely in the area of power-to-X. The first co-operation agreement was concluded as early as 2008. In this, the focus is on joint research projects as well as bilateral developments.

Technische Universität Bergakademie Freiberg contributes many years of experience in the field of hydrocarbon synthesis and applied research, up to demonstration scale. In addition, with its unique infrastructure, it provides the basis for large-scale generation and analysis of the products.

As an engineering company, CAC adds years of expertise in the planning and realisation of complex chemical plants. The demonstration plant for synthetic gasoline was erected in 2009 on the basis of laboratory findings, as the first and thus far largest of its kind in Germany. In the years that followed CAC has worked with its own funds as well as in the scope of multiple funded research projects, including with the IEC, to further development, patent technology and prepare for market-ready, large-scale production.

Since 2017, research co-operation has also continued within the KEROSyN100 project. Seven project partners from the fields of research and industry are working together to prepare electricity and methanol-based kerosene for market. To achieve this goal, the first power-to-liquid plant for the manufacture of synthetic kerosene via the methanol route was developed. The Heide refinery in Schleswig-Holstein is earmarked for the realisation of a corresponding demonstration plant. More on KEROSyN100


The Closed Carbon Cycle Mobility joint project - C3-Mobility for short - for climate-neutral fuels was initiated in 2018 and ended in November 2021. It was co-ordinated within the scope of the Energy Transition in Transport funding initiative of the Federal Ministry for Economic Affairs and Energy, aimed at the use of electricity-based fuels. The goal was to illustrate new approaches to the CO2-neutral mobility of the future. To achieve this, 32 partners joined together to form a cross-sectoral consortium ranging from energy supply, process engineering, automobile and commercial vehicle manufacturing to research and development. They examined the manufacture and use of various methanol-based fuels. The application and technical feasibility of synthetic fuels was assessed as satisfying the criteria of standard fuels already in use: for all engine sizes and serial production vehicles. This required the demonstration of all applicable test scenarios, such as long and short distances or real driving emissions, RDE for short, the measurement of emissions in actual road traffic. At the digital closing event on 23 and 24 November 2021, 23 international project partners presented their findings to the 190 guests.

Chemieanlagenbau Chemnitz (CAC) is building a chlor-alkali electrolysis plant for KEM ONE, Europe's second largest PVC manufacturer. The contract volume amounts €57 million, this being the largest order of this kind in the history of the Chemnitz-based company.

KEM ONE, headquartered in Lyon, France, awarded CAC a contract for the construction of a modern, energy-efficient and environmentally friendly membrane electrolysis plant as a replacement for the existing diaphragm electrolysis plant at the end of 2021. CAC will implement the plant at the Fos-Sur-Mer site in France together with its long-standing Japanese technology partner Asahi Kasei Corporation as an EPCm project. Specifically, this means that CAC will be responsible for basic and detail engineering, procurement and supply, site management, and commissioning support.

"We are pleased that we were able to convince KEM ONE of our performance capability, flexibility and experience and that we managed to conclude the contract under pandemic conditions”, says Mike Niederstadt, Managing Director of CAC.

The plant, which is located on the coast of southern France, is to be successively converted to using sea salt as feedstock. This independent raw material supply makes it possible to react more flexibly to any supply bottlenecks in the future. The Fos-sur-Mer plant produces chlorine, caustic soda and hydrogen from salt by means of electrolysis. The chlorine produced is used on site to manufacture vinyl chloride monomer, the basic substance for PVC. This material is flame retardant, insulating and resistant to chemical attack, wear and tear. It is therefore suitable for a wide range of applications in construction, packaging and medical technology.


KEM ONE is a leading European producer of polyvinyl chloride (PVC), used mainly in construction, packaging, and medical applications, and caustic soda. With 1,400 employees and 8 industrial sites located across France and Spain, Kem One has leading positions in both mass and suspension PVC in Europe, and recognized expertise in specialty PVC, including paste PVC and post-chlorinated PVC.

Mit e-Fuels zur Verkehrswende: CAC und TU Bergakademie Freiberg zeigen Vorteile ihrer grünen Kraftstofftechnologie

E-Fuels CAC

Am 6. September hielt das e-Fuels-Forum im Rahmen seiner Deutschlandtour an der Demonstrationsanlage der TU Bergakademie Freiberg, wo Chemieanlagenbau Chemnitz (CAC) gemeinsam mit der Universität synthetisches Benzin produziert. Die Technologie bietet großes Potential für die Klima- und Energiewende.

Umweltfreundliche Kraftstoffe, die in jedem Verbrennungsmotor eingesetzt werden können und dennoch dem Klima nicht schaden– Was klingt wie eine Zukunftsvision, haben das Institut für Energieverfahrenstechnik und Chemieingenieurwesen (IEC) der TU Bergakademie Freiberg und Chemieanlagenbau Chemnitz (CAC) bereits gemeinsam umgesetzt. Mit ihrem marktreifen Verfahren können die beiden Partner bereits jetzt synthetisches Benzin aus Methanol herstellen, das aus Kohlendioxid (CO2) und „grünem“ Wasserstoff (H2) erzeugt wird – ganz ohne fossile Rohstoffe.

Dieses ist nicht nur klimaneutral in der Herstellung, sondern lässt sich auch problemlos als Zumischung in die Automobil-Bestandsflotte (ca. 1,4 Mrd. Fahrzeuge weltweit) tanken. Die Demonstrationsanlage an der TU Bergakademie Freiberg kann bereits heute 100 Liter pro Stunde herstellen. In einer ersten industriellen Anlage sollen es bis zu 50.000 Tonnen werden, ab 2024 dann bis zu 250.000 Tonnen pro Jahr. Ziel ist bis 2030 jährlich eine Million Tonnen synthetisches Benzin. „Diese Menge leistet bei einem jährlichen Verbrauch in Deutschland von etwa 16 Millionen Tonnen Ottokraftstoff einen wichtigen Beitrag zur Erfüllung der Klimaziele“, erklärt Jörg Engelmann, Geschäftsführer CAC.

Aus 100 Prozent grünem Strom hergestellt

Um große Mengen an regenerativ gewonnener Energie für die Energiewende in Deutschland zur Verfügung zu stellen, ist Import aus energiebegünstigten Ländern notwendig. Hier kommt ein weiterer Vorteil von strombasierten synthetischen Kraftstoffen, auch e-Fuels genannt, ins Spiel: Umgewandelt in e-Fuels beziehungsweise deren Rohstoffe Wasserstoff und Methanol ist „grüner“ Strom in großen Mengen transportbar und damit hierzulande nutzbar.

CAC und das IEC arbeiten bereits seit 2008 auf dem Gebiet Power-to-X – also sinngemäß etwa „aus Strom mach X“ – eng zusammen. „Das X kann dabei vieles sein: Neben Benzin lassen sich auch Diesel, Kerosin, Methanol, Ammoniak, Gas oder Flüssiggas aus CO2 und Wasser herstellen. Alles, was man braucht, sind Strom, Katalysatoren und Reaktoren.“, erklärt Prof. Dr. Martin Gräbner, Direktor des IEC. Wissen, von dem auch die Studierenden an der TU Bergakademie Freiberg profitieren. In Studiengängen wie dem Verfahrenstechnik und Chemieingenieurwesen (Diplom) oder Engineering (Bachelor) lernen sie beispielsweise, wie man aus Plastikmüll oder Agrarreststoffen nachhaltigen Kraftstoff herstellen kann. Ihr Wissen können sie an den einzigartigen Demonstrationsanlagen der Universität dann auch gleich praktisch anwenden. Das macht die Absolvent:innen zu gefragten Experten für wirtschaftliche und klimaneutrale Umwandlungstechnologien. Viele sind später auch in der Industrie tätig und bringen ihr Wissen bei Unternehmen, wie CAC ein, um Technologieinnovationen der Zukunft voranzutreiben.

Einzigartige Demonstrationsanlage dient für Herstellung von e-Fuels

Die Demonstrationsanlage für synthetisches Benzin wurde 2009 als bundesweit erste ihrer Art auf Basis der Laborergebnisse zu Kohlenwasserstoffsynthesen der TU Bergakademie Freiberg errichtet. In den folgenden Jahren hat CAC mit eigenen Mitteln sowie im Rahmen mehrerer Forschungsprojekte, gefördert vom Bund und dem Freistaat Sachsen, die Entwicklung weiter vorangetrieben, die Technologie patentiert und für die marktreife Großproduktion vorbereitet – politische Weichenstellungen vorausgesetzt.

Beim e-Fuels-Infotour-Halt am 6. September in Freiberg stellten die TU Bergakademie Freiberg und CAC gemeinsam mit der Lühmann Gruppe, dem UNITI Bundesverband mittelständischer Mineralölunternehmen und dem Bundesverband Freier Tankstellen (bft) Gästen aus Politik, Presse und Öffentlichkeit die Anlage, die Technologie dahinter und die Vorteile von synthetischem Kraftstoff sowie deren Potential mit Blick auf die Klima- und Energiewende vor und beantworteten Fragen. Auch Autoexperte Jean Pierre Kraemer, bekannt als JP Performance, war schon zu Gast am IEC und berichtet im August 2021 über die einzigartige Technologie und Anlage. Zum Video

HUGO PETERSEN Auftrag Bad Köstritz

Zum Fernsehbeitrag des MDR Thüringen, 08.07.2021

Tochterunternehmen der CAC errichtet neue Anlage zur Erzeugung von SO2 und Schwefelsäure

HUGO PETERSEN GmbH (HP) wurde als EPC Partner für die Planung und Errichtung einer Neuanlage zur Herstellung von flüssigem Schwefeldioxid und Schwefelsäure beauftragt. Für das Chemiewerk Bad Köstritz (CWK) in Thüringen übernimmt HP somit die Gesamtverantwortung in allen Phasen des Projektes, in das der Kunde etwa 20 Millionen Euro investiert.

Die Schwefelsäureanlage basiert auf der eigenen Technologie HUGO PETERSENs und soll bis Anfang des 4. Quartals in Betrieb gehen.

Eine Besonderheit bei der Umsetzung lag laut Axel Schulze, Geschäftsführer der HP, in der spezifisch an den Kunden angepassten Integration der Anlage in das Gesamtkonzept der CWK. Zusätzlich war die verhältnismäßig kleine Größe der Anlage besonders herausfordernd.

CWK verfolgt mit dem Neubau das Ziel, seine Rohstoffe künftig kosten- und energieeffizienter selbst zu produzieren. Bislang müssen sie nach eigenen Angaben 12 Tonnen Schwefeldioxid zukaufen. Mit der eigenen Produktion sparen sie zukünftig etwa 2,5 Millionen Euro im Jahr und reduzieren die CO2-Emission, indem ca. 30 Prozent des bislang verbrauchten Erdgases eingespart werden wird. Das produzierte Schwefeldioxid und die Schwefelsäure bilden die Grundlage für Produkte, die in der Landwirtschaft oder Bauindustrie genutzt werden.


Das Chemiewerk Bad Köstritz ist ein Hersteller von anorganischen Spezialchemikalien. Seit mehr als 180 Jahren werden am Standort in Thüringen hochwertige Materialien für Anwender der verschiedensten Branchen hergestellt.

HUGO PETERSEN GmbH ist ein Ingenieurunternehmen im chemischen Anlagenbau mit Sitz in Wiesbaden und seit 2005 als Tochtergesellschaft in die CAC-Gruppe integriert. Seit 1906 ist HP einer der weltweit größten Technologiegeber für Schwefel- und Salzsäureherstellung sowie Gasreinigungsprozesse.

CAC completes commissioning of newly built chlorine drying facility for AO Sayanskkhimplast and modernizes the existing sulphuric acid concentration

In spite of the pandemic-related circumstances that have had a major effect on aspects such as supply chains and travel, the project could be completed already with a successful test run following around eighteen months of planning and realisation.

AO Sayanskkhimplast, the largest Russian manufacturer of polyvinyl chloride, assigned Chemieanlagenbau Chemnitz (CAC) with the construction of a new chlorine drying facility and modernisation of the existing sulphuric acid concentration operations at the site of Russia’s first chlor-alkali electrolysis plant with membrane technology in Sayansk, Irkutsk region. The membrane electrolysis plant was planned and implemented by CAC in 2006 and was expanded in 2013 to enable an annual capacity of 180,000 tonnes of chlorine gas. “Sayanskkhimplast has been one of our longest-standing customers since our founding in 2004. I am very proud that in spite of numerous political and currently pandemic-related circumstances we have consistently managed to maintain trust-based co-operation and that we have once again contributed to the expansion of the leading market position of Sayansk,” states Jörg Engelmann, CEO of CAC.

With this follow-up assignment CAC undertook the basic and detail engineering, the supply of equipment, installation supervision and support during commissioning.

AO Sayanskkhimplast OJSC

The history of AO Sayanskkhimplast as a production complex dates back to 1968. It is one of the largest polyvinyl chloride manufacturer in Russia and is based in Sayansk, Irkutsk region. The company produces chlorine and caustic soda as well as the bleaching agent Belizna. AO Sayanskkhimplast is a modern, dynamically evolving company, one of the market leaders in the Russian chemicals sector. In recent years the existing production capacity has been consistently extended and modernised to maintain and further expand this position.

OMV invests nearly 200 million euros in industrial plant following development of innovative co-processing technology

Chemnitz, March 1, 2021: Chemieanlagenbau Chemnitz (CAC) has been assigned by OMV with overall responsibility for the construction of a biofuel plant. With this project CAC is realizing one of the first large-scale plants in Europe to use innovative co-processing to produce carbon-neutral fuels. For this purpose biogenic input materials are processed together in combination with fossil, oil-based raw material in a hydrogenation facility at the refinery. The Vienna-based international oil, gas and chemicals company is investing about 200 million euros in the conversion at the site in Schwechat (Austria). This is in line with the EU requirement for biofuels to adhere to strict ecological and social criteria throughout the value chain.

With this process, the hydrogenated vegetable oil should lead to an annual reduction in OMV’s carbon footprint of up to 360,000 metric tons of fossil CO2. This is equivalent to the annual emissions of around 200,000 cars driving an average of 12,000 km per year. The product meets the highest quality standards and can be freely used in any type of vehicle. The technology applied is not limited to vegetable oil – waste products (such as used cooking oil) and advanced feedstocks are also possible and will be used based on availability. OMV expects demand for its hydrogenated biofuels to increase ten-fold by 2030.

“With this project we are joining OMV in taking a further step towards sustainable mobility,” declared Jörg Engelmann, managing director of CAC, which is currently launching its technology for manufacturing synthetic gasoline on an industrial scale onto the market. “Only with technological openness we can provide rapid and sustainable protection for our environment.”

With overall responsibility for all phases of the project, CAC is undertaking detail engineering, including project management and project controlling, procurement services and construction site management. This includes the supply of equipment and bulk materials (piping, instrumentation, electrotechnical material) as well as responsibility for construction and assembly work.

Chemnitz, January 21, 2021: Chemieanlagenbau Chemnitz (CAC) has successfully completed a water electrolysis plant at the RWE site in Niederaussem, North Rhine-Westphalia as part of the international, globally unique research project ALIGN-CCUS. The goal of this project is to develop a technological chain for reducing CO2 emissions and put this into operation. This will see CO2 separated directly from industrial emissions, as it can be captured in far higher concentrations there than in the air. Assigned by Asahi Kasei Europe GmbH, the licensor for the water electrolysis, CAC successfully undertook the approach of planning, procurement, assembly and commissioning. For CAC, this is the first plant with this newly-developed technology.

The plant consists of skid mounted modules with the water electrolysis as well as a hydrogen compression and hydrogen treatment unit. The electrolyser developed by Asahi Kasei and integrated into a fully-automated plant separates water into hydrogen and oxygen. The CO2 obtained from an existing RWE facility and the hydrogen as produced are the feedstocks to produces dimethylether (DME), which can subsequently be transformed into synthetic fuels.

ALIGN-CCUS research project
In the ALIGN-CCUS project 34 companies, research institutes and universities from throughout Europe are pursuing the goal of transforming six European industrial regions into economically robust centers with significantly reduced CO2 emissions by 2025. The partners received 15 million euros of funding at European and national level, working in six interlinked research areas on carbon capture, utilization and storage (CCUS). ALIGN-CCUS is the only project of its kind worldwide to construct and test a fully-integrated carbon capture and utilization chain (CCU) in an actual industrial environment.

On 10/08/2020 Michael Kretschmer joined with representatives of Saxon industry on a visit to CAC to discuss climate-neutral mobility

Chemnitz, 11/08/2020: On 10/08/2020 the Prime Minister of Saxony, Michael Kretschmer, took up the invitation of Chemieanlagenbau Chemnitz GmbH (CAC) to find out about synthetic fuels as an opportunity for the swift implementation of climate goals. CAC has developed a market-ready process to generate CO2-neutral gasoline (E-fuels) comprising only carbon dioxide, green electricity and water - completely without fossil fuels.

The opportunities that this technology can offer motor vehicle manufacturers, refineries, industry and ultimately climate protection within the shortest of times were discussed by Michael Kretschmer and representatives of Saxony industry at CAC, supported by the council of economic advisers of the CDU. Open to future-capable innovations, the premier was impressed by the progress made with the CAC technology, stating: “I can see the advantages that the synthetic gasoline offers, as it can be used to power any existing gasoline engine with no conversion required.”

The experts from the car industry, science and politics agreed that the ambitious goals of the EU Commission concerning climate neutrality by 2050 can only be achieved by embracing new technologies, but not through E-mobility alone. Various different forms of power are called for, depending on the benefits offered and areas of use. The electric car makes sense for urban travel of up to around 50 kilometres per day, whilst the amount of space required for fuel cells makes these better suited to larger vehicles. For all cars between these two options there is currently no climate-friendly solution available. “Synthetic gasoline can close this gap by being blended with existing fuel or even replacing it completely. The climate goals set by the federal government can be reached immediately, the existing infrastructure with filling stations can continue to be used and each of the 30 million gasoline engines in Germany alone can be powered with more climate-friendly gasoline,” says Joachim Engelmann, managing director of CAC. “It can be used immediately, with no extra effort required, we just need to build the plant.” A further key incentive called for is the crediting of the fuel to the fleet consumption of the German car manufacturers. A policy framework needs to be established for this. The currently higher costs compared to standard gasoline can be reduced further by larger plants with higher capacity, facilitated by tax incentives. In the short term, blending with standard gasoline at a rate of 14 percent can satisfy the requirements of the renewable energy directive (RED II).

There was a critical discussion of the stability of the German climate protection strategy with regard to the situation in China. A pioneer in battery-powered propulsion, this year the Chinese government undertook a partial about-turn in favour of combustion engines. Prime Minister Kretschmer took numerous ideas and arguments back to Dresden with him, with the intention of providing political support for these in the future. He also sees a further positive step in the development of synthetic kerosene, which CAC is also successfully working on in a parallel development.

E-fuels as an opportunity for climate-neutral mobility

After over ten years of intensive research work on the part of CAC, the Chemnitz-based engineers have developed a process for the generation of CO2-neutral gasoline (E-fuels). Both the quality of the gasoline and the technical plant design enable realisation on a large industrial scale, thereby achieving the sustainability goals of the EU (RED II) with immediate effect.

The most important process stage in the manufacturing chain is the transformation of the methanol extracted from carbon dioxide and hydrogen into gasoline. In the demonstration plant at TU Bergakademie Freiberg CAC produced more than 16,000 litres of the green gasoline in October 2019. The demonstration plant is already capable of producing 100 litres per hour. Filled and sent to car manufacturers for fleet trials, the practical applicability of the fuel has been confirmed. The goal is to produce one million tonnes of synthetic gasoline by 2030.

„Klima- und CO2-freundliches Benzin - das klingt zu schön, um wahr zu sein. Wissenschaftlern der Chemieanlagenbau Chemnitz GmbH (CAC) und TU Bergakademie Freiberg ist genau das gelungen. Das "grüne Benzin" hat gleich mehrere Vorteile, sagen die Forscher." Sehen Sie den TV-Beitrag des MDR Sachsenspiegel vom 17.12.2019.

Green fuel is already market-ready

PM CAC grünes Benzin

Twelve tonnes of CO2-neutral fuel have been produced as a climate-friendly alternative to petroleum and electric cars

Chemieanlagenbau Chemnitz (CAC) has developed a process for producing green, that is, synthetic, fuel from carbon dioxide, electricity and water alone – entirely without fossil fuels. At the demonstration plant at Freiberg University of Mining and Technology – the most important process stage, the conversion of methanol into fuel – twelve tonnes of green fuel have already been produced and made available to car manufacturers for testing.
Joachim Engelmann, CEO and CAC shareholder, is convinced that "synthetic fuels are the future of mobility". "We are assuming that in the future, cars will increasingly use synthetic fuel or diesel." By 2030, according to the EU's Renewable Energies Directive RED II, the renewable share of fuels should be 14 percent – that is double the amount it is today. “The great advantage of synthetically produced fuel – besides the main goal of reducing CO2 emissions – is that car manufacturers can use it to further develop their internal combustion engines, that clean fuel can be compatible for the existing fleet of cars and that it is also widely available through the existing network of fuel stations", according to Engelmann.
Indeed, all major car manufacturers are researching alternatives such as electric drives or fuel cells, but the bottom line is that their global warming potential is currently higher. The advantage of the CAC process is that fuel can be produced almost CO2-neutrally, since only CO2, water and electricity – ideally from renewable sources – will be required for production.
"There are many who are interested in our process", says Joachim Engelmann, "but so far no industrial-scale plant has been built. Our most important goal is to build such a plant, because the technology is market-ready", according to Engelmann, who is already engaged in promising negotiations with a refinery abroad: "Germany is not taking the issue seriously enough: The new climate protection agreement does indeed refer to the aviation industry or trucks, but passenger cars have been omitted for synthetic fuels. Politicians are fixated on the electric car in a manner that is difficult to achieve. If Germany does not recognise synthetic fuels as a strategic goal, as plant manufacturers we have to orient ourselves towards other countries in which these technologies have a future."

The research and development work is to be promoted by the federal government and the Free State of Saxony as part of the "C3-Mobility" research project. Nevertheless, more than 50 percent of the funds invested in the project are CAC's own funds.


In general, the topic is known under the name Power-to-X – thus meaning something like "making X from electric power". At the same time, the X can be many things: In addition to fuel, it is also possible to produce diesel, kerosene, methanol, ammonia, gas or liquid gas from CO2 and water. All that you need are electricity and various catalysts.
The CO2 needed for the production of hydrocarbons comes from the air or ideally even from industrial exhaust gases. In these the CO2 content is up to 500 times that in "normal" air. If the carbon dioxide were to be collected directly from an industrial plant, almost no exhaust gases will be produced there. This socalled carbon capture becomes a win-win situation both for industry as well as for synthetic fuel production, which needs precisely this CO2. The necessary hydrogen is obtained from normal water using the process of electrolysis. To do this you require electricity – and if it also comes from sustainable energy sources, CO2 emissions will be reduced. As a model project, CAC, together with Mitsubishi Hitachi Power Systems Europe GmbH (MHPSE), has developed and simulated a complete process chain including hydroelectric power generation. The goal of the project is to produce a synthetic high-octane fuel that is almost completely CO2 neutral.
"Using carbon dioxide as the basis for producing synthetic fuel is a unique selling point of the CAC technology", according to Joachim Engelmann. "There are indeed global competitors who are likewise researching synthetic fuels or have also built plants, but they cannot process the CO2 directly." The idea of using excess CO2 for fuel production turns an unwanted byproduct into a valuable commodity. Industrial companies with high CO2 emissions would not even have to release their carbon dioxide into the environment, but instead could immediately introduce it as a raw material into the cycle for fuel production. The CO2 savings could be reckoned up by using emission certificates. "However, the legal basics are not yet being regulated in our favour", says Joachim Engelmann and he hopes that legislation will soon recognise the advantages of the new process and classify the synthetic fuel produced in the CAC demonstration plant as a clean fuel.

INEOS Phenol gives the kick-off for construction work on October 1st, 2019

Chemieanlagenbau Chemnitz GmbH (CAC) is building a world scale cumene plant for INEOS Phenol in the Evonik Chemical Park Marl, Germany. For CAC, this project is the largest EPC services contract since CAC was founded 55 years ago. The capacity of the new plant is rated for 750,000 tonnes of cumene per year. The unit making use of existing pipeline connections between INEOS Phenol phenol and acetone production in Gladbeck, the Evonik Chemical Park Marl and the BP refinery and cracker complex in Gelsenkirchen. The construction of the plant will secure the supply of raw materials to the plants in Gladbeck and Antwerp for the coming decades. Commissioning is planned for the 3rd quarter 2021.

With the planning and construction of a reactor weighing approximately 300 tonnes and several distillation columns, it becomes a representative reference project for the CAC division of classical petrochemicals. "We are very pleased to implement this strategically important major project for INEOS Phenol" explains Mike Niederstadt, COO of CAC.


INEOS Phenol is a part of INEOS Group and, according to its own figures, the world's largest producer of phenol, acetone and cumene. Cumene serves as an intermediate product for the production of phenol and acetone at INEOS Phenol’s plant in Gladbeck. From 1954 the capacity there has increased 80-fold, from an initial 8,000 tonnes to 650,000 tonnes per year.

With this new plant, INEOS Phenol secures its own cumene source for the future. Thus it is a valuable and strategic investment for the future of INEOS Phenol and the Chemical Park Marl.

Chemnitz wheelchair user Til (15) is taking part in the first German paraskate world championships, from 30/08 to 01/09/19.

"When life gives you lemons, make lemonade,” is how Til Augustin describes his approach to life. The 15-year-old Chemnitzer is wheelchair-bound due to a congenital regression syndrome, a complex malformation of the lower spine – and has undergone numerous operations. Each operation is a new first for the doctors, because Til’s body is a biological one-off. However, this does not keep him from participating in sport: he acknowledges no limits, he simply gets on with it. He sails, skis and now he skates as well.

This ambition has already made him German champion twice, although he has only been involved in the sport for around a year. Now he wants to compete against the best in this sport - and is taking part in the first paraskate world championships to be held outside of the US, at the North Brigade in Cologne. He completes the WCMX, short for “WheelchairMX”, in his new, specially-adapted wheelchair. A special wheelchair for skating has a larger wheelbase and good suspension in particular. It was built in Brazil and fitted with a special bucket seat tailored to his size. Such equipment costs several thousand euros, money that Til’s mother, a single parent of eight children, could not afford without donations. “Til is an incredibly pleasant young man who proves that he can get the best out of life with ambition, perseverance and courage,” said Jörg Engelmann, managing director of CAC. “We are delighted that we could support him with a donation and keep our fingers crossed for him in the world championships.”

As a Chemnitz-based company, we were greatly shocked by the recent events. First and foremost, we are deeply saddened by death of a young man. The perpetrator or perpetrators are to be brought to justice with every legal means of our functioning legal state and democracy.

We abhor the instrumentalisation of this act by extremists of every hue. This results in the city, its citizens and the companies located here suffering reputational damage that is unjustified and sets the exemplary development of our city back by years.

Chemnitz has been able to develop so positively precisely because it has embraced internationality and multilateralism thanks to the businesses, educational and cultural establishments, associations and committed citizens of the city. – And this commenced with the beginning of the industrial rise of Chemnitz in the 19th century.

To all employees, customers and business partners, as well as visitors to our website:

Chemnitz is neither grey nor brown (

With this statement, uttered so often in recent days, we at Chemieanlagenbau Chemnitz GmbH wish to play our part in ensuring that the unpleasant events of the last few days cause no lasting damage to our city.

For openness to other cultures, tolerance and peaceful coexistence

Chemieanlagenbau Chemnitz GmbH has successfully finished the construction of a new plant for benzene enrichment for Total Raffinerie Mitteldeutschland GmbH (TRM). For TRM, it was currently the largest completed investment project in Leuna. For CAC, this meant the successful continuation of a long tradition in the realization of plants at the Central German refinery site. Total invested 30 million euros in the new plant.

Significant milestones

The lifting and installation of the partition wall column in March 2017 was one of the milestones of construction. This column with a height of 65 meters and a weight of 245 tons is the core piece of the new plant. Just one week later followed the installation of the assembly unit, which has a weight of 35 tons and consists of four air coolers. Contrary to what had originally been planned in the basic engineering, the complete assembly of the partition wall column was carried out on the basis of pre-dressing. This means: The column was delivered to the construction site in three pieces with a length of 20 meters each. Then it was welded on site in horizontal position. Next, all attachments - fixed ladders and operating platforms, insulation, piping including insulation as well as cable trays were mounted to the horizontal column. Finally, the column was erected and set up in one piece.

During the project phase, all site employees, including CAC colleagues, worked approx. 134,000 hours - this corresponds to more than 15 years of life. They moved 7500 m³ of earth mass, installed 147 t of steel and 558 m of railing.

In the course of plant construction, CAC was responsible for detail engineering, procurement services, expediting and inspection, site management, participation in pre-commissioning, commissioning and performance test run.

Flying on Green Fuel

CAC is part of a joint project for the production of electricity-based, green kerosene. The Federal Government will support the project over the next three years with some four million euros.

In cooperation with five other partners from industry and science, Chemieanlagenbau Chemnitz GmbH (CAC) is researching the production of environmentally friendly synthetic kerosene. It is also called electricity-based fuel. For the KEROSyN100 research project, CAC undertakes the development of innovative technology for the synthesis of methanol into kerosene. In contrast to conventional fossil fuels, the goal is to produce kerosene by using renewable electricity. Excess wind energy from the windy Western coast of Schleswig-Holstein is used as source of electricity. Up to now, this energy generated has been subject to curtailment and was lost due to grid bottlenecks.

The engineers in Chemnitz take advantage of this abundance. “Instead of wasting excess wind energy, we use it to create the basis for synthetic fuel by means of innovative chemical processes using water and carbon dioxide”, says Jörg Engelmann, CEO of CAC. “In the ideal case, this electricity-based kerosene produced with renewable wind energy and the use of carbon dioxide from the atmosphere allows us to achieve a closed CO2 cycle.”

Since 2008, CAC has been conducting research into synthetic fuel technology together with Freiberg University of Mining and Technology. On the basis of this know-how, the Chemnitz engineers are developing the innovative technology for the conversion of methanol to kerosene. Afterwards, CAC will prepare the basic engineering for a customized demonstration plant at the site of the project partner Raffinerie Heide, which will represent the entire process chain.

After the successful completion of this project, a follow-up project is expected, in order to demonstrate the developed concept at the Heide refinery site and prove the suitability of the green fuel in real flight operations.

Under the leadership of the Advanced Energy Systems Institute (AES) of the University of Bremen, in addition to Chemieanlagenbau Chemnitz GmbH, the industrial partners Raffinerie Heide GmbH and SKL Engineering & Contracting GmbH are involved in the „KEROSyN100“ project. Science partners are the Freiberg University of Mining and Technology, the DLR - Institut für Vernetzte Energiesysteme e.V. (Institute of Networked Energy Systems) and IKEM - Institut für Klimaschutz, Energie und Mobilität e.V. (Institute for Climate Protection, Energy and Mobility)

From 11 to 15/06/2018 we were present with a stand at the ACHEMA in Frankfurt a.M., our fourth time at the fair. The world’s largest fair for the process industry is held in Germany every three years. For CAC and our subsidiary HUGO PETERSEN GmbH it is the leading fair for international business relations. With over 300 discussions with current and potential customers, service providers and suppliers, we are highly satisfied with the event. We were especially pleased with the avid interest from prospective graduates, who obtained information about CAC in the form of target group-appropriate company and technology presentations on our stand.

Our 63 m3 fair stand at the familiar location in Hall 9.1/B26 bore the fair motto “Kick-Off with an idea ahead”. On the one hand, we used this to present the “kick-off” of our new logo and the updated brochures and image film that accompany it. On the other hand, the motto was also a reference to the start of the football world cup, which we highlighted with CAC footballs and a panel discussion with legendary football trainer Hans Meyer.

We would like to thank all visitors to the fair stand and look forward to our continued positive collaboration.

Completion of a Membrane Electrolysis Plant in Germany for the First Time

Chemieanlagenbau Chemnitz GmbH (CAC) has successfully built its first chlor-alkali electrolysis plant in Germany. Until now, cli-ents and jobsites of the Saxon plant manufacturer have been primarily located in Western and Eastern Europe as well as in Russian-speaking countries. "We are very pleased that after more than 15 years of successful implementation of chlorine-alkali projects we have realized a plant with this technology in Germany," explains Jörg Engelmann, CEO of CAC.
The new plant for AkzoNobel Speciality Chemicals and Evonik Industries AG at the Ibbenbüren site was commissioned by the two companies. It will be operated by AkzoNobel within the framework of the joint venture “Neolyse Ibbenbüren GmbH”.
The new membrane electrolysis plant, based on technology of Asahi Kasei Corporation in Japan, replaces the existing mercury-based plant. The energy-saving membrane process increases economic efficiency and ensures compliance with the corre-sponding future legal requirements. According to the plant oper-ators, this new production process at the site improves the eco-logical footprint of every ton of chlorine produced in Ibbenbüren by 25 to 30 percent.

The planning order on the basis of an EPCM contract included detail engineering, procurement services, site management as well as commissioning support up to the performance test run of the plant.

The membrane electrolysis in Ibbenbüren is designed for an annual capacity of 120,000 tons of potassium hydroxide solution and 80,000 tons of chlorine. The future operation of the business is clearly defined: Chlorine as well as hydrogen produced during electrolysis will be further processed by AkzoNobel on site or sold to customers. Evonik will market the potassium hydroxide solution produced in Ibbenbüren or transport it by ship to its own site in Lülsdorf near Cologne for further processing. In Lülsdorf, Evonik processes the potassi-um hydroxide solution, inter alia, into potassium carbonate (potash).

"This project was an issue of most concern to both of us and our clients, because the new plant not only allows for an improved energy balance, but also ensures many jobs in Ib-benbüren. Therefore, I am more than pleased that we have completed this order at a high level of quality and within the agreed financial and time frame boundaries, "says Engel-mann.

Chemieanlagenbau Chemnitz GmbH builds a turnkey chlor-alkali electrolysis plant in Torrelavega in the North of Spain for the Portuguese company CUF-Químicos Industriais S.A.

The new plant is based on the modern, energy-efficient and environmentally friendly membrane electrolysis process of Asahi Kasei Chemicals Corporation in Japan. In about two years, after its completion, the plant will replace the mercury-electrolysis plant, which was shut down in 2017.

With an expected production capacity of 68,000 tons a year of chlorine, CUF, Portugal's largest chemical company, intends to strengthen its leading position in the Iberian market for chlorine and chlorinated derivatives.

"We are very proud that CUF has given us main responsibility for all stages of the order fulfilment," said Mike Niederstadt, CEO of CAC. "This order will strengthen our many years of experience as an EPC company in the international competition for major strategic projects."

In addition to the membrane electrolysers based on technology from Asahi Kasai, the scope of services and supplies includes brine preparation (filtration, softening, iodine removal, ammonia removal), caustic evaporation as well as a sodium hypochlorite unit.

CAC is responsible for basic and detailed engineering, procurement of all equipment and bulk materials, construction and installation services, construction and installation supervision as well as advisory services during commissioning.
The family-owned company CUF-Químicos Industriais S.A. is the largest Portuguese producer in the chemical industry. At the end of 2017, the company acquired parts of the chlorine factory in Torrelavega from the international chemical group Solvay and is investing 55 million Euros in these production facilities as well as in the construction of the modern chlor-alkali electrolysis plant.
