Power Sector Transformation Will Get World One Third Of Way To Net Zero – IEA

The report analysed more than 800 technology options to examine what would need to happen for the world to reach net-zero emissions by 2050.

The IEA said between a third and a half of cumulative emissions reductions needed come from technologies which are not commercially available today – for example, low-carbon hydrogen, which is produced by electrolysis powered by renewable energy, and technology to capture carbon emissions released to the atmosphere and store them.

A large amount of additional power generation is needed for low-carbon hydrogen, which is increasingly being viewed as a way for industries such as steel to decarbonise.

The global capacity of electrolysers needs to grow to 3,300 gigawatts (GW) from 0.2 GW today. To produce enough hydrogen to reach net zero emissions, the electrolysers would consume twice the amount of electricity which China generates, the IEA said.
