The UK’s hydrogen sector has struggled to convert policy ambition into bankable projects, with only a limited number progressing to final investment decision despite successive funding rounds. A 20 MW project in Wales has now crossed that threshold, offering a test case for whether government-backed hydrogen can move into execution.
ITM Power confirmed that its previously announced Notice to Proceed relates to MorGen Energy’s West Wales Hydrogen project in Milford Haven, which has reached FID under the UK’s Hydrogen Allocation Round 1 support framework. The milestone places it among the first projects backed by Department for Energy Security and Net Zero funding to advance beyond planning.
The UK government’s hydrogen strategy has focused on bridging the cost gap between green hydrogen and fossil-based alternatives through subsidy mechanisms. However, translating that support into investable projects has proven complex, with uncertainties around offtake agreements, price support structures, and long-term demand.
MorGen’s project suggests that a combination of industrial demand and policy clarity can unlock financing, at least at smaller scales. The plant, located at the former Milford Haven refinery site, is expected to produce around 2,000 tonnes of hydrogen annually once operational in 2028.
At 20 MW, the project remains modest compared to gigawatt-scale ambitions outlined in national strategies. Yet its progression to FID indicates that investors are beginning to accept the risk profile of hydrogen infrastructure when revenue visibility improves.
ITM Power will deploy its POSEIDON electrolysis module as the core technology. Standardization of electrolyser systems has become a key focus across the industry, as developers seek to reduce engineering complexity and improve reliability.
Electrolyser performance and uptime remain critical variables in project economics. Capacity factors, degradation rates, and maintenance costs directly influence levelized hydrogen costs, which in turn determine competitiveness against conventional fuels.
To address operational risk, ITM Power has signed a ten-year long-term service agreement with MorGen Energy. Such agreements are becoming standard in early hydrogen projects, reflecting investor concerns about technology maturity and lifecycle performance.
The inclusion of a long-term service framework also signals a shift toward treating hydrogen assets as infrastructure rather than pilot projects, with predictable maintenance and performance expectations built into financial models.
The West Wales Hydrogen project is designed to supply industrial clusters across Milford Haven, Port Talbot, and the wider Welsh region. This localized demand model reflects a broader trend in hydrogen deployment, where proximity to industrial users reduces transportation costs and infrastructure requirements.
Industrial offtake remains one of the few segments where green hydrogen can approach economic viability, particularly in sectors with limited electrification options. However, demand certainty is still evolving, and long-term contracts are often required to underpin investment decisions.
The project’s location within an existing industrial hub provides access to established infrastructure and potential customers, which may have been decisive in achieving FID. Replicating this model in regions without concentrated industrial demand could prove more challenging.
While the project demonstrates progress, its scale highlights the gap between pilot deployments and national targets. The UK aims to build a significant low-carbon hydrogen economy, yet most projects reaching FID remain in the tens of megawatts rather than hundreds.
This reflects persistent constraints, including high capital costs, limited electrolyser manufacturing capacity, and ongoing uncertainty around hydrogen pricing mechanisms. Even with government support, developers must balance policy incentives against market risks.
The role of standardized modules such as POSEIDON may help accelerate deployment by reducing engineering timelines and improving cost predictability. However, scaling will depend on whether similar projects can achieve FID in larger numbers and at increasing capacity levels.
