The initiative will focus on bringing down the cost of technologies that will enable the U.S. to achieve a net-zero emissions energy system by 2050, a crucial benchmark for preventing runaway global warming. First up is the “Hydrogen Shot” —  a goal to get the cost of clean hydrogen from $5 per kilogram down to $1 by 2030, or an 80 percent drop.

“Clean hydrogen is a game changer,” Energy Secretary Jennifer Granholm said in a statement. “It will help decarbonize high-polluting heavy-duty and industrial sectors, while delivering good-paying clean energy jobs and realizing a net-zero economy by 2050.”
