Hydrogen Optimized enhances RuggedCell for Mauritanian green hydrogen project

Hydrogen Optimized, a subsidiary of Key DH Technologies, established high performance benchmarks for its proprietary RuggedCell water electrolyzers in a simulation of variable power situations at the 30 GW AMAN green hydrogen project in Mauritania.

Renewable energy developer CWP Global leads the project. In a net zero scenario, green hydrogen will meet 15% of global energy needs by 2050.

To meet global demand and secure a net zero future, CWP Global is producing a large portion of green hydrogen by 2030. CWP Global inked an MOU with Hydrogen Optimized to investigate integrating 500-750 MW RuggedCell green hydrogen reactors with its wind and solar portfolio.

Hydrogen Optimized’s Owen Sound High-Power Demonstration Facility simulated broad swings in RuggedCell electrolyzers’ electrical power input to match the Mauritania project’s wind profile. RuggedCell technology efficiently uses intermittent energy from renewable sources like wind and sun to produce consistently clean hydrogen gas across a wide range of electrical power input. Previous investigations showed that the RuggedCell dynamically adapts to electrical current levels from 0 to 100% power demand in seconds.

Large-scale green hydrogen plants powered by intermittent renewable energy need this capability to be profitable. Remote “island grids” power CWP’s projects.

The simulation showed that the RuggedCell efficiently provides steady hydrogen gas purity over the complete dynamic range of power provided by real-world intermittent renewable energy situations. Simulation showed that the RuggedCell’s thermal stability maximizes energy efficiency.

The RuggedCell does not require gas-liquid circulation pumps, in contrast with most other water electrolysis systems. As a result, there are no parasitic power loads that would otherwise diminish the system efficiency and reduce hydrogen production.

CWP Global is considering co-locating RuggedCell electrolyzers with wind and solar power plants in Australia, Mauritania, Djibouti, and elsewhere. Ammonia manufacture would use green hydrogen. The new facilities will be built starting in 2026.
