thyssenkrupp expands green hydrogen production

Green hydrogen is gaining in importance worldwide as an energy carrier and CO2-free feedstock for the chemical industry. As a result, demand is rising for industrial electrolysis plants that can produce green hydrogen cost-efficiently. thyssenkrupp has expanded its manufacturing capacities for such electrolysis plants and can now produce electrolysis cells with a total power consumption of up to 1 GW per year, together with its strategic supplier and joint venture partner De Nora. These production capacities will be extended continuously in the future.

Green hydrogen, produced by electrolysis using renewable electricity, is essential for a successful energy transition and for meeting international climate targets. Hydrogen is not only a clean energy carrier and fuel; it is also a CO2-neutral feedstock for the production of green chemicals. With expertise in the engineering and construction of chemical plants, thyssenkrupp can already realise entire value chains, from the large-scale production of hydrogen to the subsequent manufacture of sustainable base chemicals such as ammonia and methanol. In corresponding industrial processes this makes it possible to dispense with fossil raw materials and reduce CO2 emissions directly at source.

“Especially in energy- and resource-intensive industries such as fuel, chemical or steel production, only green hydrogen opens the way to climate neutrality. For this, we need water electrolysis on a GW scale. We can deliver, and as the number and size of hydrogen projects increases we will further expand our production capacities,” said Christoph Noeres, head of Energy Storage & Hydrogen. “But one thing is also clear: it won’t work without changed regulatory conditions and fair market opportunities for green hydrogen. In addition to the further expansion of renewable energies, the focus is on adjusting tax systems and crediting the CO2-reducing effect of green hydrogen in the target markets.”

To simplify the construction of new hydrogen plants and keep costs down, thyssenkrupp offers its electrolysers in prefabricated skid-mounted modules. One module produces 4000 cubic m of hydrogen per hour. The units are easy to transport and install and can be combined to realise projects of several hundred MW or GW. Due to their high reaction speed, the plants can be operated flexibly; for the production of green hydrogen for industrial power-to-x applications as well as for grid stabilisation.

The patented design of the electrolysis cells, equipped with proprietary anodic and cathodic coatings developed by De Nora, allows high system efficiencies of up to 80%. It is based on electrolysis technologies from thyssenkrupp. So far, more than 600 projects and electrochemical plants worldwide with a total rating of over 10 GW have been realised by the company.
