Strategic collaboration with Rheinmetall for the Giga PtX project

We are pleased to announce that we have entered a strategic collaboration with Rheinmetall AG, a leading international technology group in the defence sector. The collaboration will focus on Rheinmetall's Giga PtX project, which aims to establish a Europe-wide network of decentralised synthetic fuel production plants for the NATO armed forces, designed to strengthen defence energy resilience, sovereign fuel capability and operational readiness.

The project envisages the deployment of several hundred decentralised production plants across Europe, each with an electrolysis capacity of up to 50 MW, capable of producing approximately 5,000 to 7,000 tonnes of e-fuel per annum per facility.

By combining Rheinmetall's Power-to-X expertise with ITM's market-leading electrolyser systems, the parties are bringing together their capabilities, know-how and strong market reputation. The collaboration will initially focus on the UK.

Synthetic fuels are expected to play a critical role in defence and other mission-critical sectors, where electrification is not viable, and a secure, reliable fuel supply is essential. The Giga PtX project therefore represents a significant potential growth market for large-scale hydrogen production technologies, underpinned by increasing focus on resilient and independent energy supply in defence applications.

Dennis Schulz, CEO of ITM Power, said: "Our collaboration with Rheinmetall aligns the energy transition with national security priorities. Reliable access to fuel is fundamental to defence capability, and decentralised production offers a structurally more resilient alternative to traditional supply chains. The Giga PtX project represents a repeatable deployment opportunity for large-scale electrolysers, while directly supporting sovereign fuel capability and operational readiness. By combining Rheinmetall's system integration capability and defence experience with our leading electrolyser technology, together we are well-positioned to deliver scalable solutions."

Shena Britzen, Head of Hydrogen Program at Rheinmetall AG, said: "e-Fuels are more than a technological solution - they are a strategic necessity. With Giga PtX, we are creating a scalable network that strengthens energy autonomy for Europe's defence forces. What matters is not just energy security, but the ability to act independently - in logistics, in operations, and in times of crisis."
