SungreenH2 uses nanotechnology and advanced materials to create the world's highest performance electrolysers for green hydrogen production at a low cost.


Problem: Today’s electrolysers, the key equipment used to make green hydrogen, are expensive and inefficient. As a result, green hydrogen is 5x more expensive than fossil-fuel based grey hydrogen. SunGreenH2 have developed proprietary nanostructured materials and used nanocrystal engineering to boost the performance and reduce the cost of electrolysers. We are developing a modular, scalable, high efficiency Anion Exchange Membrane (AEM) Electrolyser system for green hydrogen production at low cost. This opens the door for widespread adoption of green hydrogen by transport, industry, and energy storage. We are thus unlocking sustainable, scalable, on-site green hydrogen production globally.

Unique Value Proposition: Electrolyser systems built with our developed materials show the following competitive advantages compared with the traditional technology:

  • Ability to operate at high current density and in a wide dynamic operating range i.e. superior compatibility with renewable energy
  • World leading efficiency with 200% increase in production
  • 10% decrease in energy consumption
  • 50% lower space requirement (due to reduced stack size)
  • 33% lower electrolyser capex cost


  • Awarded “Breakthrough capex cost improvement in H2 production” at Ruhr Summit Germany
  • Exploring joint technology development with leading global engineering company for marine applications
  • Test-bedding our AEM electrolyser in Singapore 
  • Recent potential stack trial opportunity with leading European utility company
