The MIT Alumni for Climate Action group on Advocacy and Policy led by Jeremy Grace, PhD, published a position paper on Green Alternative Fuels. (See https://maca.earth/). This paper examines the appropriate production and use of green alternative fuels in the context of a transition to a net-zero economy. General points articulated in the paper written for maximum clarity for citizens and government representatives include (i) Hydrogen and other green alternative fuels are not a one-to-one substitution for fossil fuels; and (ii) They should be used appropriately only where direct electrification is not possible. Any green alternative fuel, including hydrogen and ammonia, must be produced in a manner that complies with the “three pillars” of the 45V Hydrogen Production Tax credit. These pillars are necessary to ensure that scale-up of green hydrogen production does not impede the needed deep cuts in CO2 emissions.
