Sheffield's ITM Power signs strategic collaboration with Germany's Rheinmetall to develop European synthetic fuel network for NATO armed forces, backed by 150 MW RWE capacity reservation
ITM Power, the Sheffield-based electrolyser manufacturer listed on the London Stock Exchange, has entered a strategic collaboration with Rheinmetall, the German defence and technology group, targeting the development of a Europe-wide synthetic fuel production network for NATO armed forces. The collaboration centres on Rheinmetall's Giga PtX project, which aims to establish several hundred decentralised Power-to-X (PtX — a process that converts surplus renewable electricity into hydrogen or synthetic fuels) production plants across Europe. ITM Power's role is to supply electrolysers — the devices that split water into hydrogen and oxygen using electricity — to power the network. In parallel, ITM Power has secured a separate capacity reservation agreement with RWE, the German energy group, covering 150 MW of its Neptune V electrolyser systems, with call-offs (firm purchase orders drawn against the reservation) foreseen by 2027. The RWE deal builds on an existing commercial relationship. The dual announcement is significant for several reasons: it positions ITM Power at the intersection of two of Europe's most active policy themes — defence infrastructure spending and green hydrogen industrial deployment. For legal teams, the collaboration involves complex technology transfer agreements, multi-jurisdictional offtake and capacity reservation contracts, and supply agreements governed across English, German, and potentially NATO-framework legal instruments. The defence dimension also raises export control and dual-use regulation questions under both UK and EU regimes.
Why this matters
The ITM Power–Rheinmetall collaboration reflects the convergence of two distinct capital flows: rising European defence procurement budgets (NATO members accelerating spending post-Ukraine) and the EU's push to build sovereign green hydrogen capacity. For energy and technology practices, this creates demand for advice on technology licensing, capacity reservation agreements (which allocate manufacturing output before firm orders are placed), and offtake contracts for hydrogen and synthetic fuels. The export control dimension is material — hydrogen electrolysis technology with defence applications sits close to dual-use classification thresholds under the UK Export Control Order 2008 and EU Dual-Use Regulation. The 'why now' context is Rheinmetall's rapid pivot from a pure defence manufacturer to an industrial energy technology integrator, seeking to lock in electrolyser supply from a UK-listed specialist ahead of anticipated demand.
On the Ground
A trainee on this type of energy technology transaction would assist with due diligence on the IP portfolio (reviewing ITM Power's electrolyser patents and licensed technology), summarise grid connection agreement terms and planning permission/licence conditions for the PtX plant sites, and coordinate regulatory filing requirements under UK export control rules for technology transfer to a German defence counterparty.
Interview prep
Soundbite
Defence-driven hydrogen demand is creating a new offtake category — electrolyser suppliers now negotiate with NATO procurement frameworks, not just utilities.
Question you might get
“What export control considerations would arise when a UK technology company like ITM Power transfers electrolyser technology to a German defence contractor for use in a NATO synthetic fuel programme?”
Full answer
ITM Power, the AIM-listed Sheffield electrolyser manufacturer, has signed a strategic collaboration with Rheinmetall to build a synthetic fuel network for NATO armed forces across Europe, alongside a 150 MW capacity reservation deal with RWE. This is commercially significant because it locks in long-term electrolyser demand from defence procurement — a buyer category with very different contracting norms, security requirements, and payment terms from commercial energy clients. For law firms, the work spans technology licensing, capacity reservation and offtake contract drafting, and export control compliance given the dual-use nature of the technology. It reflects a broader trend of European defence spending driving industrial-scale green hydrogen investment, which will sustain energy and technology transaction volumes into 2027. The RWE reservation deal separately signals that major utilities are beginning to commit to specific electrolyser volumes ahead of regulatory hydrogen mandates.
