Green hydrogen was pushed to the fore last week when Fatih Birol, head of the International Energy Agency, said the technology was “ready for the big time” and urged governments to channel investments into the fuel. Most hydrogen used today is extracted from natural gas in a process that produces carbon emissions, which defeats the object for many policymakers. But there is potential to extract “green” hydrogen from water with electrolysis, an energy-intensive but carbon-free process if powered by renewable electricity.
