ITM Power: The December 2026 Decision That Could Seal the Hydrogen Story

A single milestone now dominates the narrative around ITM Power: the final investment decision for the Cromarty green hydrogen project in Scotland, due in December 2026. That date will test whether the British electrolyser maker can convert its expanding pipeline of partnerships and state backing into credible revenue—or whether the stock’s recent volatility is a sign of deeper execution risk.

The shares have already shown how quickly sentiment can swing. On Tuesday, ITM Power climbed 16% to €1.62, propelled by renewed interest in the UK green hydrogen sector and a bullish analyst note. Berenberg’s Alex Smith nearly doubled his price target to £2.00, reiterating a “Buy” rating and pointing to the company’s pivot toward defence and industrial energy security as a game-changer. At the same time, the stock still trades 37% below its 52-week high of €2.58, having recovered from a February trough of €0.65. Year to date, the shares are up more than 109%, but the path has been anything but smooth.

Smith’s upgrade was triggered in large part by ITM Power’s collaboration with Rheinmetall on the Giga-PtX project, which aims to supply green hydrogen for military energy needs. That partnership, alongside a formalised alliance with Protium Green Solutions to co-develop industrial hydrogen plants in Britain, has shifted the company’s focus beyond pure decarbonisation into fast-growing, high-value end markets. The Cromarty project, which Protium is leading, will reach a final investment decision in December 2026—a concrete deadline that will test the credibility of ITM Power’s project pipeline.

Should investors sell immediately? Or is it worth buying ITM Power?

Government support is equally central to the story. The UK Department for Energy Security and Net Zero has committed a strategic equity investment and a grant of £46.5 million toward ITM Power’s new Chronos electrolyser platform in Sheffield. The Chronos system is designed to cut production costs by 40%, and the company expects it to underpin revenue of £40–43 million in fiscal 2026. The transaction is still subject to clearance from the UK competition authority, with a deadline at the end of June. Meanwhile, Great British Energy acquired a £40 million equity stake in the spring, reinforcing the state’s bet on domestic hydrogen manufacturing.

ITM Power has also signed a memorandum of understanding with DB Systemtechnik, a subsidiary of Deutsche Bahn, to study green hydrogen solutions for rail transport and critical infrastructure. The partnership includes a feasibility study for ITM electrolysers at Deutsche Bahn sites, opening another potential revenue stream beyond stationary power and industrial applications.

Yet the bullish narrative is shadowed by persistent execution risk. The company is still loss-making, and analysts do not expect a positive operating result before 2028—and that assumes flawless scale-up of production. Historical teething problems with ramping up manufacturing have bruised the stock before, and the Chronos facility must prove it can be brought online efficiently. The 30-day annualised volatility stands at over 112%, and in the month before Tuesday’s rally the shares lost 26%. The RSI of 47, after a mid-June reading that was neutral, suggests the recent consolidation may have ended, but the broader market remains jittery.

Competition, slow infrastructure build-out, and policy shifts in the hydrogen sector all add to the uncertainty. For now, investors are betting that the defence and transport angles give ITM Power a more resilient business model than the pure-play renewables crowd. The twin test—the government grant decision by end of June and the Cromarty FID in December 2026—will determine whether the stock’s recent gains are the start of a sustainable recovery or just another volatile spike in a long, bumpy journey toward profitability.
