A new technological approach will be subjected to long-term studies in a pilot plant created for the purpose. The technology will permit the production of hydrogen with a high output pressure through electrolysis

Project objective

Electrochemical storage is a very practical solution to allow the use of renewable energy sources such as the sun or the wind. An efficient and environmentally friendly method being developed at the Westphalian Energy Institute is energy storage using hydrogen produced in polymer electrolyte membrane (PEM) electrolysis. In this process, electric energy is transformed into chemical energy and stored. The objective of the project is to build a pilot plant to test the capacity of the new system to function in an industry-relevant context.

Project innovation

Electrolysis systems, which produce hydrogen with a high output pressure have a much higher efficiency because they can feed the produced gas directly into a compressed gas storage facility or pipeline without the need for an additional compressor. This lowers costs and improves the plant’s efficiency. For this purpose, the project is applying a method developed at the Westphalian Energy Institute, the hydraulic compression of individual cells. The plant demonstrates this innovative technological approach at a level close to industrial requirements and will be part of the new hydrogen technology centre planned by the company iGas energy in Stolberg, Germany. Hydrogen is produced using renewable energy sources and is thus CO2-free; it will be stored after production and used in other processes.
