Re-imagined Electrolyser Cell Design

At Next Hydrogen, our water electrolysers generate clean hydrogen more efficiently than traditional water electrolysers and at a lower cost.

To do this we introduced the first significant advancement in alkaline electrolyser cell design in decades.

While some of the world’s brightest minds with strong capital resources have been focused on improving cell materials and components, improvements to the electrolyzer cell design architecture has garnered very little attention and it has not changed in decades.

Our team with a combined 60+ years in water electrolysis dedicated years to revolutionizing the design architecture of the electrolyser and has been awarded 40+ patents (more pending) across multiple jurisdictions. Our break-through innovation in cell design architecture provides unprecedented flexibility to capture the output of intermittent renewable electrical energy using significantly smaller or fewer units than traditional electrolyser solutions.

Next Hydrogen electrolysers are inherently scalable and make it economical to generate hydrogen on site from various sources of electrical energy, including renewables, at utility scale.

  • Elimination of common flow manifolds and external piping enables high and safe gas and fluid flow rates. This enables path to multi-MW systems and significant economies of scale to drive down the cost of green hydrogen.
  • Next Hydrogen electrolysers operate at a meaningful scale for grid management and renewables integration, providing utility-scale dispatchable loads and hydrogen for energy storage.
  • Electrolysers come in pre-assembled, drop-in formats for easy, rapid installation even at utility scale
  • Next Hydrogen electrolysers use proven materials and functional components with known life cycle costs which are bank financeable.

Our break-through innovation in cell design architecture provides unprecedented operational flexibility to capture the entire output of intermittent renewable energy using significantly smaller or fewer units than a traditional electrolyser solution.

  • Our unique design removes the fluid-gas flow restrictions which limit the operating flexibility of traditional alkaline electrolysers.
  • Next Hydrogen electrolysers can accommodate a wide range of fluid (liquid and gas) flows in each “half cell” of our new and innovative cell module design.
  • Our design enables as much as 2x higher current density using the same active surface area compared to leading competitors. This allows you to generate more hydrogen when the wind blows or the sun shines, or when electricity prices are cheap.

Next Hydrogen electrolysers are purpose-built for highly variable operation, making them ideal to handle sudden fluctuations, fully capture intermittent renewable power sources and for grid-balancing.

  • Next Hydrogen electrolysers manage fluid and gas flow at a cellular level compared to competitors which use external gas-liquid separators.
  • This allows for ramp rates which are materially faster compared to traditional alkaline systems and comparable with those expected using more expensive PEM cells.
  • Ability to fully capture intermittent renewable energy resources improves project economics.
