CHEMICAL CONVERSION

Conventional hydrogen production is based on the fossil resources natural gas or coal. An alternative is offered by water electrolysis, which splits water into hydrogen and oxygen by electricity. When renewable electricity is used, it is called green hydrogen. A water electrolysis consists of individual very flat cells in which the electrochemical process takes place. Several of these cells are stacked together to form an efficient overall system with aggregates for water supply and gas removal. Water electrolysis is currently entering the market. The first large-scale plants already exist throughout Germany.

Chemical conversion at HYPOS includes various types of water electrolysis and associated systems, which are being researched and improved. In addition to PEM, alkaline and high-temperature electrolysis, HYPOS is also researching other types of electrolysis such as reversible membrane electrolysis or chlor-alkali electrolysis:
