ITM POWER UK LIMITED

Their core work

ITM Power is a Sheffield-based manufacturer of PEM (Proton Exchange Membrane) electrolysers — the machines that split water into hydrogen and oxygen using electricity. They build electrolyser systems ranging from small off-grid units to multi-megawatt industrial installations for refineries and grid balancing. Their equipment is deployed across hydrogen refuelling stations, renewable energy storage systems, and heavy industrial decarbonisation projects. They are one of Europe's leading commercial electrolyser companies, bridging the gap between laboratory-scale hydrogen technology and full industrial deployment.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), ITM Power focused on proving PEM electrolysis across diverse use cases: off-grid renewables (ELY4OFF), grid balancing (HPEM2GAS), hydrogen mobility infrastructure (H2ME, NewBusFuel), and island energy systems (BIG HIT). From 2018 onward, their focus shifted decisively toward large-scale industrial deployment — the REFHYNE projects alone account for over EUR 12.5M in funding and target multi-megawatt electrolysers for refinery decarbonisation. Their most recent projects (OYSTER, MultHyFuel, PRHYDE) show expansion into offshore hydrogen and standardisation of heavy-duty refuelling, signalling a move from technology validation to market-scale infrastructure.

ITM Power is scaling up from proving electrolysis works to deploying it at industrial megawatt scale, with new interest in offshore production — expect them to pursue large green hydrogen infrastructure projects.

How they like to work

ITM Power overwhelmingly operates as a technology partner rather than a consortium leader — they coordinated only 1 of their 16 projects (NEPTUNE). They work in large, diverse consortia with 174 unique partners across 19 countries, which reflects their role as a key equipment supplier that many different project teams want on board. Their repeat presence in flagship demonstration projects (H2ME, H2ME 2, REFHYNE, REFHYNE II) suggests they are a trusted, reliable partner that consortia actively recruit for their electrolyser expertise.

ITM Power has built one of the broadest partner networks in the hydrogen sector, collaborating with 174 different organisations across 19 countries. Their partnerships span the full hydrogen value chain — from automotive OEMs and fuel cell developers in mobility projects to oil refineries and grid operators in industrial deployments.

What sets them apart

ITM Power is one of very few European companies that both manufactures PEM electrolysers and has deployed them across the full range of applications — from island microgrids to 10MW refinery installations. Their 16-project H2020 track record with EUR 24.9M in funding gives them unmatched operational data on electrolyser performance in real-world conditions. For any consortium needing an electrolyser OEM with proven deployment experience at multiple scales, ITM Power is a first-call partner.

Highlights from their portfolio

• REFHYNE
  Largest single EC contribution (EUR 6.4M) — deployed one of the world's largest PEM electrolysers at a Shell refinery, a landmark for industrial green hydrogen.
• REFHYNE II
  EUR 6.2M follow-on project scaling refinery electrolysis further, confirming ITM Power's position as the go-to partner for large-scale industrial hydrogen.
• NEPTUNE
  Their only coordinated project — focused on next-generation PEM electrolyser technology under extreme conditions, showing R&D leadership beyond their usual supplier role.
