Production of green hydrogen for energy markets
In order to bring the fluctuating availability of electricity from renewable sources into line with electricity demand, solutions are needed for the storage and subsequent use of surplus energy. Water electrolysis produces green hydrogen that can be stored for hours, days or months, converted back into electricity or used as a clean, CO2-free starting material in the mobility sector or for the production of sustainable chemicals.
Another central requirement is the need to stabilize the power grid against short-term fluctuations. As a two-in-one solution, thyssenkrupp’s industrial-scale water electrolysis process meets both criteria, allowing operators maximum flexibility and cost-efficiency: Hydrogen production is ramped up within seconds when surplus energy needs to be used and scaled back when output is low.
In July 2020, Air Products, a world leader in industrial gases megaproject development, and thyssenkrupp Uhde Chlorine Engineers, the world leader in technologies and comprehensive solutions for large-scale electrolysis plants, announced the signing of a Strategic Cooperation Agreement. The two companies will collaborate exclusively in key regions, using their complementary technology, engineering and project execution strengths to develop projects supplying green hydrogen.
thyssenkrupp will deliver its technology and supply specific engineering, equipment and technical services for water electrolysis plants to be built, owned and operated by Air Products.
Matching the need for low-CAPEX, low-OPEX, reliable technology and solid project execution to make world-scale green hydrogen projects feasible, Air Products and thyssenkrupp are committed to deploying economic green hydrogen plants in the gigawatt size.
В будущем электролизные установки thyssenkrupp смогут выступать в качестве крупномасштабных буферов для стабилизации работы электросети и быстрой и гибкой компенсации колебаний в поставках электроэнергии.
thyssenkrupp and E.ON conducted the necessary tests in an existing water electrolysis plant operating as part of the Carbon2Chem® project in Duisburg. It was shown that thyssenkrupp’s electrolyzers can increase and decrease their production at the speed required to participate in the premium primary reserve market. Prerequisites include being able to provide full supply within max. 30 seconds and maintain it for at least 15 minutes.
To simplify the construction of new hydrogen plants and keep costs down, thyssenkrupp offers its electrolyzers in prefabricated skid-mounted modules. One module produces 4,000 cubic meters of hydrogen per hour. The units are easy to transport and install and can be combined to realize projects of several hundred megawatts or gigawatts.
The patented design of thyssenkrupp electrolysis cells, equipped with proprietary anodic and cathodic coatings developed by De Nora, allows high system efficiencies. So far, more than 600 projects and electrochemical plants worldwide with a total rating of over 10 gigawatts have been realized by the company.
