Stablegrid Group has selected ITM Power as the technology partner and supplier for two energy infrastructure projects in Germany, totalling 710 MW of electrolyzer capacity. The projects are designed to operate exclusively for grid balancing and power system stabilization, utilizing underground caverns as hydrogen storage facilities to manage discrepancies between electricity supply and hydrogen consumption.

Project Details and Timeline

The first project, designated “Netzbrücke 410” and located in Rüstringen, involves ITM Power supplying a 30 MW green hydrogen production plant based on its NEPTUNE V containerized electrolyzers, including integration works. Stablegrid Group expects to make a final investment decision (FID) on this project in 2026 and has accordingly reserved ITM production capacity.

The second project involves installing 680 MW of indoor electrolyzer capacity. Stablegrid and ITM Power will commence pre-FEED work in January 2026, with the FID for this larger project anticipated in 2028.

Grid Balancing Technology and Cost Reduction

The projects will operate under a system called “Netzbrücke” or “grid bridge,” which is designed primarily to reduce “redispatch” operations. Redispatch is an intervention used to eliminate bottlenecks in the electricity grid, in which grid operators adjust power plant output by reducing generation ahead of a congestion point while simultaneously increasing generation behind it.

This intervention has become necessary due to the expansion of renewable energy, whose feed-in is weather-dependent and geographically uneven. Negative redispatch currently results in annual costs of 2-3 billion Euros to German taxpayers. The new approach, termed “complementary hybrid redispatch” or “predispatch,” aims to reduce these costs to zero while putting surplus energy to meaningful use, contributing substantial cost savings to renewable energy expansion.

Company Leadership Perspectives

Dennis Schulz, CEO of ITM Power, stated: “Partnering with Stablegrid on these landmark grid balancing projects in Germany reinforces ITM's position at the forefront of the energy transition in Europe's largest economy.”

Oliver Feller, Member of the Management Board of Stablegrid Group, commented: “With ITM Power, we have a strong and experienced partner at our side who brings the technical expertise and excellence required to implement system-stabilizing hydrogen projects of this magnitude reliably.”

Company Background Information

ITM Power was founded in 2000, and ITM Power plc was admitted to the AIM market of the London Stock Exchange in 2004. The company is headquartered in Sheffield, England, and designs and manufactures electrolyzers based on proton exchange membrane (PEM) technology to produce green hydrogen, described as the only net zero energy gas, using renewable electricity and water.

The Stablegrid Group is based in Mecklenburg-Pomerania and Hamburg and operates as a German engineering and project development company. The organization initiates, supports, and implements infrastructure projects, primarily in the renewable energy sector, across Europe.
