“Disruptive approach”: Thyssenkrupp will increase the production capacity of H2 electrolysers to 5 GW


The German Thyssenkrupp plans to increase its annual production capacity of electrolysers to 5 GW against 1 GW currently.

The industrial conglomerate also said it is involved in the three hydrogen projects that get support from the German Ministry of Education and Research (BMBF), and is testing the production, use and integration of the industrial scale system of green hydrogen (produced from renewable energy by electrolysis).

“With its comprehensive technology portfolio for all-green value chains and recycling emissions into closed-loop systems, Thyssenkrupp can represent the entire green chemicals value chain,” said Martina Merz, President of Thyssenkrupp .

“Combining this strength of our long-standing innovation-driven company with scientific research in flagship hydrogen projects is the recipe for success in implementing the national hydrogen strategy and maintaining leadership. internationally competitive technology from Germany. “

The government will support the first of three hydrogen flagship projects, H2Giga, with 8.5 million euros ($ 9.8 million) in research and development grants for large-scale alkaline electrolysis production of water (AWE).

Thyssenkrupp, through the project, aims to take advantage of scale effects and thus reduce manufacturing costs, as well as extend its existing supply chain of 1 GW of electrolysis cells to enable project volumes larger by several gigawatts per year.

“We have seen a significant shift in the size of projects towards several hundred megawatts to gigawatts in recent months, so automated, high-volume mass production is already in line with market demand today,” said Merz.

“For these orders of magnitude, simple scaling is not feasible, but disruptive approaches must be applied, which are developed, tested and optimized in individual stages as part of this project.”

The industrial conglomerate currently offers standardized 20 MW electrolyzer modules, which it says allow selective maintenance work on individual cells instead of having to replace the entire battery. In order to develop the next generation of alkaline electrolysis technology, Thyssenkrupp said it is doing completely new cell and cell development work.

The company also strives to implement the supply chain optimization processes required for mass production, including the use of robotics and automation in manufacturing and assembly.

The joint venture with electrochemical and cell manufacturer De Nora and other partners such as metal processing company Hoedtke is essential for the ramp-up of series production.

Direct H2 offshore wind production

Thyssenkrupp will also receive funding of € 780,000 for its contribution to the flagship H2Mare project aimed at developing the production of hydrogen and downstream products such as synthetic fuels, methanol, ammonia and synthetic methane directly at sea. The company said it would develop the fundamentals of the project up to the engineering stage.

Siemens Energy, which coordinates the project, had already announced in August that H2Mare would be supported by 100 million euros from the German government.

Thyssenkrupp said it can offer various integrated green value chains based on its water electrolysis technology, including green ammonia, methanol and synthetic natural gas (SNG) production processes.

The third flagship project in which the company is involved is the TransHyDE project which studies the potential of the ammonia cracking process.

Over long distances, transporting ammonia as a hydrogen carrier is more profitable.

“After transporting green ammonia and converting it back from liquid ammonia to its constituents hydrogen and nitrogen where hydrogen is required, the hydrogen produced in this way can be directly used,” Thyssenkrupp explained.

“Potential applications include, for example, its use in steel mills, as a green power supply for chemical plants or in fuel cells to be converted into electrical energy. “
