About the increase of the generation of Green Hydrogen until 2050ões-em-estímulos-para-fontes-de-energia-limpa


An interesting statistical analysis by Potsdam Institute for Climate Impact Research et alii about scaling up “green” hydrogen was published last September 2022 at Nature.

Using information from the the International Energy Agency (IEA) hydrogen projects database , which tracks more than 1,300 electrolysis projects globally, the study concludes that the capacity of electrolysers would need to grow 6,000-fold by 2050, from today’s levels of 600 megawatts (MW), in order to help limit warming to 1.5C.

But would that be possible ?

The study suggests that even if electrolyser capacity grows as quickly as wind and solar power, it is still likely to fall short of this trajectory, and supply less than 1% of global energy by 2035.

All this depending on inevitable uncertainties, such as "a substantial risk of a long-term gap between likely supply and potential demand", industrial costs and supply chain bottlenecks. Policy support and technologycal developments are also key. Continuously for de coming decades.

The researchers add that only emergency-like growth rates, similar to those achieved by the USA for military equipment in the second world war, or China's contruction of its high-speed rail network, would enable green hydrogen to meet ambitious targets.

It should be noted that some of the main economies in the world are pushing ahead with policies such as the EU’s hydrogen “Important Projects of Common European Interest” (IPCEI) projects and the US Inflation Reduction Act .
