An old problem solved anew. We store energy.
On-site storage of
hydrogen on a
Gigawatt-hour scale
HyDepot - The local seasonal giga-storage for green energy
During the feed-in process, hydrogen is converted with CO2 to methanol.
When hydrogen is fed out, the CO2 is recovered in liquid form in a patented process and held in reserve for the next feed-in operation.
Pipe storages into which liquids (methanol, liquid CO2) are fed and discharged either as underground storage tanks or installed in 40-foot containers
No compression of hydrogen gas
Liquid storage media minimize energy requirements for feeding into the storage system. Low reaction enthalpies.
Liquid storage medium contains 107 kg H2/m3
HyDepot storage systems can be designed up to a capacity of 100 t H2 (equivalent to a lower heating value of 3.3 GWh) without safety requirements according to the SEVESO III directive taking effect.
Exploiting low-price phases on the electricity market to build up local energy reserves of several GWh
Bypassing high-price phases on the electricity market
Cost-optimized operation of high-temperature or reduction processes via the power grid
Exploiting low-price phases on the electricity market to build up local energy reserves of several GWh
Bypassing high-price phases on the electricity market
Maintaining H2 reserves to safeguard fuel supply in the event of a blackout or other failure of H2 generation facilities.
Avoidance of grid-related shutdowns of power generation plants
Provision of control power
Medium-term and seasonal energy storage
