SunGreenH2 is a Singapore-based startup that manufactures high performance electrolyser components to produce green hydrogen.
Technology
SunGreenH2 has proprietary electrodes that double hydrogen production whil consuming 20% less energy than conventional electrolyzer technologies. The startup's electrodes do not use any platinum group metals[1].
Traction
In October 2025, SunGreenH2, together with Australia-based startup SolidHydrogen, secured AUD 2.5 million to implement a 2kW prototype in French Polynesia and a 20kW pressurised system in Indonesia to validate commercial-scale production and performance[2].
In July 2022, the startup was awarded a grant under an S$8 million EMA-Shell startup partnership supported by Enterprise Singapore.
Accolades
SunGreenH2 has won the following accolades:
- Won the Climate Impact Innovations Challenge 2024, receiving part of the Rp10 billion total prize pool in grant funding to pilot their solution in Indonesia[3].
- Selected as a 2023 winner in the Bloomberg New Energy Finance Pioneer competitor[4].
The startup is also an Unreasonable venture[5].
