Hydrogen’s Hard Turn: ITM Power Marries a £46.5m Grant with Real-World Durability Data

UK clears £46.5M grant for ITM Power's automated Sheffield factory; company publishes durability data with Gore to address hydrogen sector's credibility gap.

The green hydrogen sector is entering an unforgiving new phase, and ITM Power is positioning itself with two moves that speak louder than any futuristic slide deck. While the company has just secured a substantial state grant, it is also quietly bolstering the technical evidence that the market now demands.

Britain’s competition authority has cleared a £46.5 million grant from the government, allowing the electrolyser manufacturer to proceed with a comprehensive financing package totalling £86.5 million. Great British Energy, the state-owned energy supplier, provided the remaining £40 million via a share placement in the spring. With regulatory approval secured, the formal grant agreement is expected to be signed shortly.

The capital will be deployed to build an automated factory in Sheffield, where ITM Power plans to serial-produce its next-generation Chronos platform. These electrolysers are engineered for industrial-scale efficiency, consuming significantly less energy than earlier models. Management’s target is to reach an annual production capacity of one gigawatt by 2028.

Yet financing alone no longer convinces a sceptical investor base. The market has grown tired of grand hydrogen promises and now demands proof of reliability, cost-effectiveness and commercial viability. That context makes ITM Power’s collaboration with W. L. Gore & Associates particularly significant. Together, the two companies have published a whitepaper featuring improved long-term durability data for proton exchange membrane electrolysis — precisely the kind of hard evidence the industry has lacked. The paper addresses a critical gap: the absence of comprehensive, publicly available long-term data under realistic operating conditions, especially as the sector pushes toward thinner membranes for higher efficiency.

“It’s no longer about whether the technology works,” the report underscores. “It’s about whether it operates efficiently, safely and reliably in the field.”

The stock price mirrors this shift from euphoria to scrutiny. ITM Power shares closed at €1.50 on Wednesday, having rallied 16.61% over the past week. But the 30-day picture tells a different story: a decline of 29.94%, highlighting how quickly optimism can evaporate when concrete delivery is questioned. Year-to-date, the stock has still more than doubled — up 106.06% — and on a 12-month view the gain stands at 56.71%. Yet it remains 42.01% below its 52-week high of €2.58, with a colossal 130.71% gap above the year’s low of €0.65.

Technically, the shares are trading 14.83% below their 50-day moving average of €1.76, but comfortably above the 100-day average of €1.28 and the 200-day line of €1.05. The 41.95% premium to the 200-day average suggests the broader recovery trend is still intact, even after the recent pullback. The relative strength index stands at 46.9, signalling neither overbought nor oversold territory. More striking is the annualised 30-day volatility of 114.90% — a measure of how uncertain the market remains about the company’s fair value.

Later this summer, management is expected to release full-year results for the financial year that ended in April. Analysts will be watching for a detailed timeline on the Sheffield expansion and, crucially, evidence that the technical credibility established with Gore is translating into commercial contracts.

The hydrogen industry has lost trust through missed deadlines and overhyped announcements. In that environment, a grant provides the capital, but durability data provides the argument. ITM Power’s challenge now is to turn a technical milestone into a financial one.
