For more flexibility and redundancy in the energy system of the energy transition pavilion, it has a power-to-gas unit (PtG module). As the name promises, this excess green electricity can be converted into green gas.
The method behind this process is the electrolysis of water, which imitates parts of the photosynthesis of green plants in a highly simplified form. During electrolysis, water is produced with the help of renewable electricity or an electrical voltage separated into hydrogen (protons) and oxygen. If this splitting takes place on a proton-permeable membrane, PEM electrolysis (acid electrolysis) spoken.
In this way, around 4.5 kWh renewable electricity (electrical energy) can be temporarily stored in 1 cubic meter of H2 (chemical energy).
In March 2022, the company entered Hysata in Nature communications Paper on an innovative electrolysis process released, the Hysata technology being a Energy efficiency of 98 percent achieved and thus enables an efficiency leap of another 10 percent compared to the currently best electrolysers on the market.
