The DoE is taking a play on "moonshot" to "EarthShot" and is starting to talk about them: [ref]
The climate crisis calls for a different kind of moonshot. The Department of Energy's “Energy Earthshots” will accelerate breakthroughs of more abundant, affordable, and reliable clean energy solutions within the decade. They will drive the major innovation breakthroughs that we know we must achieve to solve the climate crisis, reach our 2050 net-zero carbon goals, and create the jobs of the new clean energy economy. The Energy Earthshots target the remaining solution points of the most challenging technical problems across our energy economy.
WASHINGTON, D.C. — U.S. Secretary of Energy Jennifer M. Granholm today announced the U.S. Department of Energy (DOE)’s new goal to reduce the cost of grid-scale, long duration energy storage by 90% within the decade. The second target within DOE’s Energy Earthshot Initiative, “Long Duration Storage Shot” sets bold goals to accelerate breakthroughs that store clean electricity to make it available anytime, anywhere and support more abundant, affordable, and reliable clean energy solutions.
WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today announced $52.5 million to fund 31 projects to advance next-generation clean hydrogen technologies and support DOE's recently announced Hydrogen Energy Earthshot initiative to reduce the cost and accelerate breakthroughs in the clean hydrogen sector. Clean hydrogen is a form of renewable energy that—if made cheaper and easier to produce—can have a major role in supporting President Biden's commitment to tackling the climate crisis.
