Once viewed as a superfuel that could decarbonise large chunks of the economy, the likely uses are shrinking dramatically
Not so long ago, hydrogen looked like the next big thing, offering a way to decarbonise great swaths of the economy and perhaps even heat homes.
At one point, scenarios for low-carbon hydrogen saw demand rising from virtually nothing to as much as 800mn tonnes per annum (Mtpa) by 2050, or around 20 per cent of the global net zero energy mix. The vast majority of this was expected to be “green”, produced by splitting water molecules using renewable electricity, with a residual share for “blue”, made by stripping out and capturing the carbon in natural gas.
