Green hydrogen

Experiment demonstrating production of green hydrogen

This group is focused on developing low-cost methods of producing green hydrogen.

Our Aim

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
  • Recyclable
  • 15-year maximum payback period

Currently we are focussing on battolyser technology

Our projects

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
  • Modelling
  • Prototyping
  • 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.
