That 70% energy loss in round trip conversion to hydrogen doesn’t look so bad if the alternative is 100% loss by not running the turbines.

That really depends on the capex of the hydrogen equipment. It has to be extremely low to justify not curtailing.

>>epista+Di
Technically it depends on the levelized cost of hydrogen, which encompasses capex, opex, and a slew of other relevant inputs. Similar "levelized cost" formulas are used throughout the utility sector to make these kinds of decisions; what makes green hydrogen unique is simply that it is undergoing a spike in research and development right now that is drastically changing some of the inputs to the LCOH equation.
