Rolls-Royce has announced its first step in the hydrogen production market with the recent acquisition of a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer. Germany-based Hoeller Electrolyzer’s innovative technology will form the basis of a new range of mtu hydrogen electrolyzer products from its Power Systems division.
Hydrogen electrolysis is the process of using electricity to split water into hydrogen and oxygen. Electrolysis uses DC electricity for water electrolysis, producing hydrogen at the negative pole and oxygen at the positive pole. This makes it possible to produce carbon-neutral hydrogen by using electricity from renewable sources such as solar or wind.
The electrochemical reaction takes place in a cell between plate-shaped electrodes separated by membranes. Hundreds of cells located one above the other and pressed together form a…
