MoreH2 advances two complementary electrolysis technologies:
Proton Exchange Membrane Water Electrolysis (PEMWE)
PEMWE uses a solid polymer membrane in a compact “zero‑gap” cell design, enabling up to ten times higher current density than conventional alkaline electrolysis and an almost instantaneous response to fluctuating renewable power. This makes PEMWE very well suited for direct coupling to wind and solar, but today’s systems rely on titanium bipolar plates with noble‑metal coatings, which drive around half of the total stack cost and limit large‑scale deployment
Solid Oxide Electrolysis (SOEC)
SOEC operate at 700–800 °C and convert steam to hydrogen and oxygen with around 20 % lower electricity consumption than alkaline or PEM electrolysers, and system efficiencies up to about 25 % higher when integrated with external heat sources or exothermic processes such as ammonia or e‑fuel synthesis. SOEC stacks mainly use abundant, low‑cost ceramic and metallic materials, but their interconnects face corrosion and degradation in the hot, humid environment, which is currently a key barrier to long‑lifetime, gigawatt‑scale deployment
Together, these innovations aim to enable gigawatt-scale installation of high-performance electrolysis systems.
