P2H2 wins Enel Green Power Green Hydrogen Challenge
Power to Hydrogen (P2H2) named winner of Enel Green Power's Green Hydrogen Challenge after beating off stiff competition.

As part of Enel’s ongoing commitment to identifying the most-promising disruptive production technologies to improve the competitiveness of green hydrogen, Enel Green Power, in partnership with Enlit, has announced the winner of the Green Hydrogen Challenge.
Following a rigorous selection process, Power to Hydrogen (P2H2) has been named the overall winner.
“We were honoured to be recognised in this international competition as one of the leading companies bringing down the cost of clean hydrogen," confirmed Dr Paul Matter, P2H2’s Co-founder & Technology Lead
Based in the US and co-founded by Paul Matter and Chris Holt in 2019, P2H2 has developed a proprietary electrolysis system (The Clean Energy Bridge or “CEB”) based on an innovative hybrid Anion Exchange Membrane (AEM)/liquid alkaline cell-stack design.
P2H2’s advanced AEM electrolysis technology cost-effectively produces high-pressure hydrogen with industry-leading efficiency. Its proprietary stack design also solves common durability challenges associated with AEM cells, while the cell design eliminates or reduces expensive or rare materials like titanium, platinum and iridium.
As the Challenge Winner, P2H2 has the opportunity for future collaboration within the Enel Green Power innovative activities in the green hydrogen field.
“With Enel’s broad renewable portfolio, we see significant opportunity to support their mission to decarbonise energy and industry, and look forward to exploring collaboration to expand the global adoption of green hydrogen,” added Dr Matter.

Launched by Enel Green Power at Enlit Europe in Milan last year, the Green Hydrogen Challenge is part of Enel Green Power’s commitment to bringing down the cost of green hydrogen to less than US$2/kg by 2030.
From a technological perspective, this requires a drastic reduction in the costs of hydrogen production, as well as an equally important increase in efficiency and reliability.
According to Enel Green Power, achieving these objectives is feasible by taking a collaborative approach and creating a direct link between technological expertise and those related to market needs and the integration with renewables.
Enel Green Power has an ambitious green hydrogen development plan and a key aspect of it is a strong commitment to scouting the best companies that share the same market objectives and the same roadmap to achieve them.

As part of the award, the winner, P2H2, along with the six Highly-Commended companies have the opportunity to participate for free in Initiate’s Start-up Alley at this year’s Enlit Europe, which is taking place in Frankfurt from 29 November to 1 December.
“It was a pleasure to work with Enel Green Power on their Green Hydrogen Challenge and launch it at last year’s Enlit Europe”, says Dr Heather Johnstone, Director of Initiate @ Enlit Europe.
“Such exciting initiatives that connect disruptive small ventures and established industry players are a central pillar of our Initiate programme and are of fundamental importance if we are serious about the energy transition. We congratulate P2H2 and the highly-commended organisations on their success, and wish them well for the future.”
