ITM Power: Government Cash and a 2026 Timeline Test the Hydrogen Rally

ITM Power shares slide 8% in a week despite MSCI index entry, £40M state investment, and a new green hydrogen partnership, highlighting market focus on execution.

The past month has delivered a heady cocktail of policy endorsement, index inclusion, and strategic dealmaking for ITM Power — yet the shares have lost around eight percent over the past seven days. The disconnect between headline catalysts and near-term share price action underscores a market that is pricing in ambition but waiting for execution.

Latest trading around €2.04 leaves the stock more than three times its 52-week low of €0.65, but still well off the recent peak of €2.58 struck just days ago. That two-year high reflected a burst of momentum from two overlapping events: entry into the MSCI United Kingdom Small Cap Index and a £40 million injection from Great British Energy, the state energy agency.

The MSCI inclusion at the end of May triggered a mechanical buying wave from passive funds, pushing daily trading volume to 27.6 million shares — far above the norm. Institutional investors, many of whom had previously kept the hydrogen sector at arm’s length, now have a reason to hold the stock. Great British Energy’s £40 million stake, representing 10.8 percent of the company, makes it the second-largest shareholder and sends a clear political signal: the UK government views ITM Power as a pillar of its national hydrogen strategy.

That state backing is earmarked for two specific initiatives. The first is “Chronos”, a next-generation electrolyser stack designed to double power density to 2.5 MW per square metre, with each unit delivering 2 MW of output. The second is a planned £46.5 million government grant to build a fully automated production line targeting an annual capacity of one gigawatt, with commissioning pencilled in for 2028.

Separately, ITM Power this week announced a strategic partnership with Protium Green Solutions for green hydrogen projects across the UK. The framework agreement gives ITM’s wholly-owned subsidiary Hydropulse — which builds, owns and operates containerised hydrogen plants — two potential routes: either deploy its own plants under the build-own-operate model, or have Protium directly acquire ITM electrolyser assets. The structure remains flexible, and no binding commitments have been signed.

The first real-world test of the arrangement will be the Cromarty Hydrogen Project in the Scottish Highlands. The project envisages 15 MW of electrolyser capacity and a peak daily output of roughly seven tonnes of green hydrogen. It already carries a grant from the first Hydrogen Allocation Round. Protium will handle project development — power procurement, permitting, infrastructure, and offtake. The consortium has set a target of December 2026 for a final investment decision.

Cromarty is the initial milestone, but Protium has flagged a broader pipeline including South Tees Net Zero, projects under the second and third Hydrogen Allocation Rounds, and unsubsidised developments. The potential is real; the revenue streams are not.

Short-term traders have already had their fun. Annualised volatility tops 100 percent, and the stock remains hypersensitive to news flow. The MSCI boost has faded, and the Great British Energy announcement has been absorbed. What remains is a long wait — until December 2026 for the Cromarty FID, until 2028 for the automated production line to go live. For now, ITM Power trades on narrative and state sponsorship, with the hard proof of execution still years away.
