Why clearer terminology for hydrogen could unlock investment and scale up production

Hydrogen could play a crucial role in decarbonising sectors such as heavy industry and long-distance transport, in which emissions are otherwise hard to abate, but it remains far from fulfilling its potential. Demand for hydrogen remains largely confined to a few traditional applications, and most of today’s hydrogen production is based on unabated fossil fuels, with production of low-emission hydrogen at a very early stage.
