3) Counterfactuals are important. Blue H2 in Marcellus has lower emissions intensity than electrolysis using grid electricity. Why? Lots of coal in OH/WV. Choice of production pathway should be based on localized analysis of available deployment options - no obvious answer to blue vs. green H2.

Interesting! However, most coal plants in the Ohio River valley are old; utility integrated resource plans do not generally plan for more (renewables cheapest, natural gas next). Nationally, coal consumption for electricity is down about 56% over the past 10 years.
