Broad-based: solutions for energy storage and hydrogen fueling stations

Energy storage and sustainable mobility are growth areas of the German energy transition: Additional storage capacities and further integration of the mobility sector with electricity generation are needed for the further upscaling of renewable energies.

Framatome in Germany uses both hydrogen and battery technology in ongoing projects: We offer a broad portfolio of technical solutions for short-term and long-term storage of energy as well as for the use of renewable hydrogen for mobility.

Hydrogen: secure energy storage through LOHC

We supplied the Smart Grid Solar research station in the Bavarian town of Arzberg with a hydrogen-based storage facility that stabilizes the electricity production of a solar plant. An electrolyzer uses surplus electricity to produce renewable hydrogen, which a fuel cell converts back into electricity when required. The hydrogen is stored in a carrier fluid: a liquified organic hydrogen carrier (LOHC) chemically bonds the hydrogen and enables safe, low-volume storage at atmospheric pressure.

Batteries of electric vehicles as grid buffers

Used traction batteries of electric vehicles still have 80 percent of their original storage capacity. We interconnect them to form stationary electricity storage facilities; storage capacity is high, from 500 kilowatts to several megawatts. The storage facility provides primary control to compensate for grid fluctuations. At low load the facility discharges power into the grid and at overload it recharges thus securing a stable supply.

Fueling stations: renewable hydrogen powers mobility

Renewably generated hydrogen takes sun and wind energy to the roads and railways. Currently, we are preparing fueling station projects based on hydrogen components manufactured by us. The focus is on local public transport with buses and trains. But industrial use is also possible, for example, for forklifts.
