Uniper Energy Storage is the overall storage operator within the meaning of the Energy Industry Act, acting as a storage system operator and marketing the entire capacity. The H-gas storage facility is connected to the THE market area (transmission system operator: Open Grid Europe) and is thus linked to the natural gas markets in Germany.
The key to maximizing green-hydrogen production is the strategic design of hydrogen infrastructure (e.g., electrolyzers, storage, and transport facilities) with renewable energy zones. This requires a coordinated planning framework for variable renewable resources and hydrogen production.
A grid-connected system allows you to power your home or small business with renewable energy during those periods (daily as well as seasonally) when the sun is shining, the water is running, or the wind is blowing. Any excess electricity you produce is fed back into the grid. When renewable resources are unavailable, electricity from the grid ...
