What is green hydrogen? In short, it’s hydrogen produced using entirely renewable electricity, which can then be used for industrial processes like creating cement or steel, among other things. That’s important because those industrial processes are currently the third-largest source of greenhouse gases in the United States, after the transportation and electricity sectors. If we can power those processes with green hydrogen instead of fossil fuels, it could go a long way toward helping the US meet its climate goals. But getting there is pretty complicated.

Three-quarters of the infrastructure expected to exist by 2050 hasn’t even been built yet. That means that the way we build infrastructure – where it goes, what it’s made of, and which energy sources it facilitates – will have a huge impact on the world’s ability to meet global climate and biodiversity goals.
