This group is focused on developing low-cost methods of producing green hydrogen.
To develop low-cost methods of producing green hydrogen that:
- Do not use exotic materials
- Have high material abundance
- Reasonable life span (robust chemistry), ease of use and repair
- 15-year maximum payback period
Currently we are focussing on battolyser technology
Much of our current work is focussing on battolyser technology. A battolyser is combined battery and electrolyser. It starts life as a flow battery that can produce hydrogen under electrolysis. The water consumption of this reaction is compensated for using a flow battery which can add water to the electrolyte to avoid a concentration increase of the electrolyte that would subsequently affect the battolyser chemistry.
Our work includes, but is not limited to:
- Early TRL chemistry investigation
- Measurement and testing
- Business case and use development
The Battolyser works by:
- Discharging as a battery when electricity demand exceeds generation
- Charging as a battery
- Use excess electricity to produce hydrogen
A battolyser was first developed in Delft University by Dr Fokko Mulder et Al based on Nickel-Iron batteries. Loughborough have been investigating alternative battolyser chemistry solutions using more abundant materials.
We are looking at two different use cases as shown below.
