The first HyGreen system was implemented in a special house: A former miners’ hut in the Alps, over 400 years old, secluded and without grid connection, but with its own water turbine.
As the watercourse is considerably reduced in winter, an energy storage system was required that could store the excess hydroelectric power over the long term.
The Hy2Green metal hydride solid-state storage system enables particularly compact storage of hydrogen at low pressure.
The space requirement would be up to 20 times greater in gas storage tanks with the same pressures. Alternatively, gas storage tanks with a pressure greater than 500 bar would have to be used in order to achieve comparable spatial conditions.
Hy2Green technology – self-sufficient energy supply based on green hydrogen, generated locally from hydroelectric power, stored as metal hydride, converted back into electricity when required – with maximum efficiency by using process heat in the generation and reconversion of hydrogen.
This is what the energy supply in the Knappenhaus is like – self-sufficient, CO2-neutral and convenient to operate. Click to get a live insight.
