Treasury's rule on qualifying for Hydrogen PTC is critical because without accurate #CarbonAccounting#hydrogeneartharxiv.org/repository/v...

Hold the phone... solar upstream emissions are enough to put H2 electrolysis GWP over 4kg/kg? I followed the references and it looks to be based on European solar with oxygen venting (no displacement or allocation). Texas solar H2 would probably be lower than 4kg/kg, but still a surprise to me!
