Green hydrogen on the horizon The most efficient way to produce green hydrogen may be to integrate electrolysers and wind turbines at offshore Locations

摘要

Hydrogen is undergoing an incredible change.It has joined the fight to decarbonise traditional industries while ensuring that its own future production is also carbon-free.Hydrogen production of 70mn t/yr is mainly used as feedstock for fertilisers and refining,with less than 5pc of this supply considered free of carbon emissions.Green hydrogen could decarbonise these existing uses-and by doing so reduce global carbon emissions by 2.5pc.But green hydrogen could also help with some hard-to-abate activities:transportation,industrial energy,heating buildings,power generation and steel production(through direct reduction of iron ore).These additional uses could lead to a dramatic rise in global hydrogen production-up to 550mn t/yr-in line with the Paris Agreement's 2°C scenario.
