Load-flexible high-temperature electrolysis
BHC: load-flexible high-temperature electrolysis
BHC (Bavarian Hydrogen Center) is a joint venture between several research institutions. It aims to find possibilities of gain and use hydrogen out of renewable sources. The second aspect of the research is to push further the development of chemical storage for hydrogen.

Increasing volatility in electricity production from renewable sources requires large storage capacities, in storage power as well as in size, with transient and alternating operation capabilities. Targeting the potential of chemical energy storage systems based on hydrogen, water electrolysis is one of the most common entry steps to this technology path.
High temperature solid oxide cells, operated alternately in electrolyser or fuel cell mode, represent an appealing approach for efficient electricity storage via hydrogen production / consumption. The work at EVT analyses the thermal balance of solid oxide electrolyser cell / fuel cell systems in order to enable highly transient operation at high temperatures and high storage efficiencies.
