28 100% RE by 2030 Which path to go? Hydrogen energy storage is not just electricity Harvesting large amounts of energy, storing it and reconversion into electricity is one thing, PtG is more than that. During charging, the electrolyzer provides thermal heat. That also happens during the reconversion of the hydrogen into electricity regardless of the technology used. That kind of a system will support: communities and industries to satisfy their hunger for thermal energy for floor heating for drying processes for growing plants in green houses which could not grown in cold environment A by-product of the ectrolyzer system for hydrogen production is oxygen. It has a high value for: medical application in regard to chronical respiratory and heart diseases for fish farming to breath the baby fishes for industrial processes like welding And of course the hydrogen also can be used for purposes different from energy storage. CO2-free mobility in cars & ferries Food industry for fat hardening As energy carrier for local heating and cooking PtG provides numerous use cases beside energy storage, which allows for an excellent utilization of the equipment.
