The patented hybrid process is based on thermochemical metal/ metal oxide water splitting technologies, by implementing an electrochemical step to vastly improve efficiency and reduce the very high temperature requirements.
The looping system circulates a metal/ metal oxide which is regenerated using already well researched and optimised metallurgical techniques. The combined system achieves remarkably high operating efficiencies of >90% to produce ultra-low cost green hydrogen gas at high pressure, ready for storage or usage
Key benefits
01.
Cost effective
Our technology can generate green hydrogen for as little as 3.4kWh/m3 (~38kWh/kg)
02.
Works at scale
Our system is ideally suited for large scale green hydrogen generation which could “piggyback” onto another industrial process (or for green ammonia synthesis feed) which can also make best use of the steam
03.
Self recycling
Very cheap green hydrogen is still generated independently & steam can be recycled/ used for electricity generation for the system itself.

The process
How it works
Step
01...
We start off by generating hydrogen in a thermochemical reaction
Step
02...
This reaction will produce hydrogen efficiently by oxidising a metal [M + H2O to MO + H2]
Step
03...
The metal oxide can be reduced back again in an electrochemical step. Reducing the metal and cycling it through the looping system means that it can be regarded as a catalyst in the overall reaction, so water is the only feed
Step
04...
This can be referred to as an ‘electrolyser’ because water is also split in the step, but is more in line with an electrodeposition cell, used in metal refining. One ‘unwanted’ biproduct in metal refining is hydrogen gas, but in the Loop it can be fully utilised
