The lead-acid battery-electrolyser is a low-cost system which makes it viable to use excess renewable energy to produce hydrogen gas. The initial market for the lead acid battery-electrolyser is using excess solar to generate green hydrogen for cooking in developing countries.
The world’s first lead-acid battery-electrolyser - invented, designed and prototype manufactured in Loughborough University’s Green Hydrogen Research Group – has been recognised with a prestigious award at the 2024 Hydrogen Awards. Dr John Barton and Dr Lizzie Ashton with their Hydrogen Award.
The accessible market for the lead acid battery-electrolyser is using excess wind to generate green hydrogen. Deploying the innovation on every offshore wind farm would ensure that wind that could not be turned into electricity and sent to the grid could instead be made into hydrogen.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
Under the cathodic working conditions of a Lead–acid battery (−0.86 to −1.36 V vs. Hg/Hg 2 SO 4, 5 mol/L sulfuric acid), a carbon electrode can easily cause severe hydrogen evolution at the end of charge. This can result in thermal runaway or even electrolyte dry out, as shown in Fig. 5.
The initial market for the lead acid battery-electrolyser is using excess solar to generate green hydrogen for cooking in developing countries. Deploying the innovation in every microgrid in Africa would deliver the following major economic, environmental, and societal benefits:

Excessive charging causes electrolysis, emitting hydrogen and oxygen in a process known as gassing. Wet cells have open vents to release any gas produced, and VRLA batteries rely on valves fitted to each cell. Catalytic caps are available for flooded cells to recombine hydrogen and oxygen. A VRLA cell normally recombines any hydrogen and oxygen produced inside the cell, but ma…
