The United States is among the leading hydrogen energy-producing countries in the world, with the nation’s access to wealth and resources putting it in a position where it can execute the most captivating energy projects. The hydrogen sector has evolved tremendously mainly because of the integration of technology and scientific expertise, which opened up greater possibilities for developers in their project endeavors. As of late, Power to Hydrogen and Repsol pushed AEM electrolysis past a 1,250-hour pilot, giving the technology a long-duration test under its belt.
Power to Hydrogen and Repsol demonstrate the power of technology
Energy companies are showing a greater willingness to experiment with technologies as they hope to predict where the energy industry is headed so that they can benefit when that time comes. However, the energy sector is evolving at such a rapid pace that it makes it difficult for developers to guess what is going to happen next.
Power to Hydrogen is a clean energy startup that specializes in Anion Exchange Membrane (AEM) water electrolysis technology to produce low-cost green hydrogen and pressurized oxygen. The company was founded in 2019 and is headquartered in Columbus, Ohio, United States. Initially, it was developed with roots in NASA.
AEM Electrolysis uses anion-exchange membrane systems to split water into hydrogen and oxygen using low-cost materials, avoiding expensive precious metal catalysts that are required by traditional systems. The technology operates below 50 kWh/kg at the system level with load-following capabilities designed to handle fluctuating renewable inputs.

There is a growing number of companies that are deciding to collaborate in the pursuit of energy projects as they have become more aware that partnerships enhance their chances of achieving success in the projects. According to a press release from Power to Hydrogen, the company has completed a rigorous pilot validating P2H2’s hybrid AEM electrolysis technology for large-scale green hydrogen production.
The project is a reflection of where the energy industry is at and where it is going, with technology being a huge determining factor in the decisions that companies make. The pilot, conducted through Repsol’s All4Zero industrial innovation hub, evaluated P2H2’s commercial-scale AEM stack across more than 1,250 hours of parametric and durability testing, including extensive operation under simulated load profiles.
It was revealed that the system either met or exceeded key performance targets across efficiency, flexibility, and durability, emphasizing AEM electrolysis as a credible, lower-cost route to renewable hydrogen at industrial scale.
Repsol is a global multi-energy company based in Madrid, Spain, that operates across the entire oil, gas, and renewable energy value chains. Its leadership body includes Antonio Brufau (Chairman) and Josu Jon Imaz (CEO).
Understanding the importance of testing technology before full-scale use
With the abundance of technology that is available nowadays, it is massively important that companies test their technology and ensure it fulfills the set expectations. Dr. Paul Matter, Founder and CEO of Power to Hydrogen, stated the following:
“This pilot proves what we’ve long believed: that AEM electrolysis can deliver PEM-like performance at a fundamentally lower cost structure. With Repsol’s rigorous testing framework and real-world operating conditions, we’ve demonstrated the durability and efficiency that the market has been waiting to see from AEM.”
Delving deeper into the Power to Hydrogen and Repsol partnership
Through the use of Repsol-specific inputs and the U.S. Department of Energy’s H2A-Lite analysis framework, P2H2 projects a levelized cost of hydrogen of approximately €3.86/kg, a ~16% reduction compared to incumbent electrolyzer technologies. The technology has the ability to reach an estimated €2.82/kg under optimized renewable energy scenarios with hybrid power purchase agreements.
Among the main focuses of the pilot was proving P2H2’s ability to operate under the variable conditions that represent real renewable power: the All4Zero test protocol included variable load profiles based on real operating conditions, with repeated cycling between 40% and 100% load.
