Hydrogen Power Generation


Sustainable Production of Hydrogen through a Hybrid Water-Splitting Loop

This technology offers significant improvements to hydrogen production through a novel loop system that’s produces hydrogen at both the anode and cathode improving. This process makes a hydrogen production a reality through high efficiency and purity.



The hydrogen economy is seen as vital component of a shift to clean energy and is expected to grow rapidly in the coming years as a renewable energy source to meet the needs in fuel cells, internal combustion engines and turbines. To meet both the demands and environmental regulations a move away from using natural gas as the feedstock must be realised.  Water electrolysers convert water into hydrogen and thus when integrated with a renewable electricity source gives a route to absolutely zero-emission process.


This patented electrolyser technology is current the only catalytic system that produces hydrogen at both reduction and oxidation cycles. The production at both red-ox process’ that must occur, to recycle the catalyst, gives step change increase in hydrogen production for a given energy input compared to other electrolysers on the market.

  • Novel continuous process – current systems only produce hydrogen in one reaction direction.
    • Red-ox (reduction-oxidation) metal/metal-oxide loop capable of producing hydrogen in both reactions.
    • None of the current processes can produce H2 in both reduction/oxidation steps.
    • Highly-efficient and highly-pure H2 production
    • uses only 2.5 kWh of energy for producing 1kg of hydrogen
    • Heat-recovery system further improved efficiency - integrating with the heat recovered from metal hydride formation, if it is used as a preferred process for hydrogen storage
    • Improved sustainability by an energy efficiency electrolyser – higher by 2.7 times compared to commercial-available electrolysers due to using a novel ionic-activator
  • Environmentally friendly - integrating the process with renewable electricity (wind, solar, hydro-power), it will be an absolutely zero-emission process.

Key Benefits
