For hydrogen power to be a climate solution, leaks must be curbed

Unlike carbon dioxide, hydrogen does not have a direct effect on climate - it affects other pollutants

We are taught at school that hydrogen burns to produce water. This is part of its image as clean fuel. But new analysis is providing warnings for the engineers who will create and operate our future energy systems.

In 2021, the UK government launched its hydrogen strategy, providing a roadmap to kickstart a hydrogen economy by 2030 that visualises a future where hydrogen could be powering the boilers that heat our homes, fuelling our transport and providing heat for chemical and steel production.
