Electrolyzers

If a fuel cell is operated in a reverse mode, hydrogen as well as other chemical energy carriers can be obtained from water and electrical energy via electrolysis. This technology is indispensable for a climate-neutral hydrogen economy in the future; the hydrogen must be produced in electrolyzers using regenerative electrical energy. Hydrogen is not only seen as a future energy carrier in the field of electromobility; greenhouse gas emissions can also be significantly reduced in industry through the use of regenerative hydrogen. In addition to hydrogen, precursor products for chemical processes can also be obtained via electrolysis of carbon dioxide, for example carbon monoxide and synthesis gases can be produced in high-temperature solid oxide cells.
