ITM Power has been named as the preferred technology partner and supplier for two energy storage projects in Germany, lining the firm up for 710MW of electrolyser orders.

The selection from German-based Stablegrid Group could see ITM provide electrolysers to its 30MW and 680MW developments aimed at producing green hydrogen during periods of surplus renewables for storage in underground caverns.

The partners say the projects’ focus on grid-balancing could be significant, noting the “grid bridge” operating mode could help reduce negative redispatch costs, which they said amount to €2-3bn ($2.3–3.5bn) per year.
