Opportunity knocks? Medical oxygen and electrolysis in Europe
Medical oxygen is a growing need around the world, with supply short in many contexts. But one potential new opportunity lies in the growth of green hydrogen production.
In the years ahead, thousands of tonnes per year of oxygen are likely to be produced on hydrogen electrolysers as a ‘free’ by-product as green hydrogen ramps up. For every tonne of hydrogen produced by electrolysis, about eight tonnes of oxygen are generated.
It means that after purification a 1MW water electrolyser could produce around three tonnes per day of oxygen, in addition to about 450kg per day of hydrogen. Beneficial use of this oxygen by-product may enhance the business case for many green hydrogen projects and could improve the availability of medical oxygen and reduce the cost of healthcare.
