Water electrolysis plant for international research project to reduce CO2 emissions

Align CCUS

Skid mounted modules of the water electrolysis plant to reduce CO2 emissions

Chemieanlagenbau Chemnitz (CAC) has successfully completed a water electrolysis plant at the Innovation Centre of RWE Power 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 CO2 utilisation and to put this into operation to reduce CO2 emissions. CO2 is directly separated from industrial sources, 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 be used as synthetic fuel.

ALIGN-CCUS research project
In the ALIGN-CCUS project 30 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. 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

Michael Kretschmer zu Gast bei CAC


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.”

After a construction period lasting 12 months to the day, on 04/06/2019 CAC and Grace celebrated the topping-out of the new plant at the chemicals park in Worms. CAC bears overall responsibility for all stages, from planning to turnkey handover of the major project in the second quarter of 2020. The steel and block work is almost completed and the equipment largely installed. Work is currently underway to install the approximately 800 pipelines. In addition, this year has also been accident free, with nearly 90,000 working hours.

The basis for the project planning is the existing production and plant know-how from an existing production site in the US. Grace GmbH, which is headquartered in Columbia/Maryland, USA, plans to use this plant at its main European site for production, research and development to cover the rising demand for colloidal silica (silicon dioxide). Silicon dioxide is used in a wide range of industrial applications such as catalysts, functional coatings and precision casting. “We are very appreciative of the trust that Grace has placed in us to realise its major European project, an investment in the double-digit millions,” states Mike Niederstadt, managing director of CAC. “Since the study in 2016 we have worked closely with Grace to implement this complex project and we are delighted to now also be constructing the plant together.”

Grace GmbH
The research, development and production site in Worms, Germany, that opened in 1972 has evolved into a centre of excellence for the manufacture of silicon dioxide as well as catalyst and adsorption technologies.

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.

CAC successfully completed multimillion project in Leuna

CAC Total Leuna

(©Michael Deutsch – Total Raffinerie Mitteldeutschland GmbH)

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.

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)

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.

Successful completion of construction of a new butadiene plant for OMV AG at the Burghausen refinery site


In March 2015 the butadiene plant at the Burghausen site entered operation as planned and has been producing reliably since that date. Last Friday saw the symbolic commissioning of the plant in Burghausen, with numerous guests of honour present.

In addition to the construction of the new butadiene plant, the engineering services of CAC also included conversion and expansion measures for the existing loading and unloading facilities, together with storage tank capacities.

The total OMV investment stood at 150 m euros, with CAC responsible for the complete engineering services, the procurement of all equipment, monitoring of assembly work and preparation for commissioning.

"We are proud that OMV has once again turned to our engineering expertise and chosen us as partner for this strategically-significant project. With its successful conclusion we have made a key contribution to the optimisation of the Burghausen refinery site," says Jörg Engelmann, Managing Director of CAC.

Background information:

Butadiene as key element for the synthetics industry
Butadiene is a gaseous, unsaturated carbon hydride that is produced in the petrochemical section of the refinery from the by-product of the C4 ethylene plant in the so-called cracking process. It represents a key element for the synthetics industry, which can only be replaced by other materials with great difficulty. The gas is used primarily in the manufacture of tyres. In combination with other materials it results in characteristics such as good grip in all weather conditions, high mileage, less wheel noise, less weight and less rolling resistance. These factors in particular make a noteworthy contribution to safety and the reduction of fuel consumption and CO2 emissions in vehicles. In addition, butadiene also plays an important role in synthetics processing in the automobile industry and the fabrication of high-quality rubber and latex products, for example in the medical sector.
