| The true colours of "Green" Hydrogen
Read this article today in the news paper. No amount of lobbying, spin etc is going to
help us violate basic physics. https://www.thehindu.com/sci-tech/en...le67462156.ece
Journalists, particularly those who write for the science section, should learn a bit about how to quote original sources as I could not figure out what is the original source. I hunted it down and I think it is this. https://climateriskhorizons.com/rese...n-Hydrogen.pdf
It is important to look at some of the points that are particularly relevant to us in the context of clean transportation. Quote:
Secondly, the clean energy used for hydrogen electrolysis must be additional.
Green hydrogen should not cannibalise existing RE supplies. Decarbonising
India’s grid is the first climate priority to reduce emissions. If existing or
already planned RE (~21% of annual generation as of 2023) is diverted to
green hydrogen production, it will delay grid decarbonisation. Due to
efficiency losses, utilising clean energy for green hydrogen delivers significantly
lesser carbon reductions than clean electrification for the grid.10,11 Opportunity
cost analysis demands that in a resource-constrained environment, renewable
energy should first be deployed to clean the grid
