Ambition and progress beyond state of the art.

H2HEAT will contribute substantially to advancing the concept of green H2 for heating (and O2) both in terms of “idea to application” and “lab to market“.

Electrolyser Advances

Alkaline based electrolysers are more mature when compared with proton (PEM) or anion (AEM) exchange membrane electrolysers. However, they typically employ expensive electrode precious metal materials resulting in cost inefficiencies and likely increasing future costs.

Stargate Hydrogen is developing advanced alkaline electrolysers based on nanoceramic active materials. The use of novel materials allows Stargate to achieve performance that is on par with widely used precious metal-based electrolysers (both PEM and precious metal-based alkaline), yet without the use of precious metals. It will be demonstrated that the materials that Stargate utilizes in its novel cells and stacks can achieve electric power consumption of 45 kWh/kg H2 at the high-efficiency operating point. Quantitatively, Stargate electrodes will demonstrate electrolysis current ≥50x higher than for IrO2 electrodes per EUR invested.
