Heat & Water Recovery

Three outputs from one system: power, heat and water.

Recover the clean heat and pure water a fuel cell already makes - lifting combined efficiency and advancing toward water circularity

EH Energy fuel cells produce electricity, heat and water.  Unlike combustion, both the heat and the water come out clean and controllable - heat in a liquid coolant loop at ~75–85 °C and water as pure, de-ionized condensate. Recovering them turns a power system into a combined heat, power and water asset, lifting electrical efficiency.

Integrated liquid-to-liquid heat exchangers and a product-water separator are built into every module as standard, with no redesign required. If heat recovery isn’t used, excess heat is rejected to ambient air, so the same product serves both configurations. Water can be cycled back into EH Reforming for water circularity - saving  water for the communities who need it.

Key highlights

  • High efficiency - Combined heat-and-power efficiency increases significantly from circularity (electrical + thermal)

  • Water circularity - Circular water loop supports EH Reforming in an integrated design

  • Heat circularity - Quality heat band (~75–85 °C) suits hydronic heating directly, providing this for adjacent building heating or data center cooling

  • Built for communities - Behind-the-meter power and onsite water recovery turn a constraint into an asset for communities competing for resources and facing escalating costs
