TL&DR summary/spoiler: Why? Because even at absurdly low costs for future green hydrogen, it's ridiculously expensive per tonne of CO2 emissions averted.
A conversation yesterday with Martin Becker, led to an interesting calculation. He wondered why I was so negative about blending hydrogen into the natural gas network, when green hydrogen might (one day, wholesale price) be available at $3/kg.
Well, first, off, the maximum percentage greenhouse gas (GHG) emissions abatement is small. The generally agreed maximum of 20% H2 into the gas network is the most it can handle without major changes to the network and replacement of all end use equipment connected to it.
https://www.linkedin.com/pulse/hydrogen-replace-natural-gas-numbers-paul-martin/
20% H2 by volume sounds like a lot, but is only 7% by energy content and hence 7% GHG emission reduction at absolutely maximum, even with hydrogen as pure and free of GHG emissions as the driven snow.
