There’s a lot of buzz going around about green hydrogen. It’s virtually emissions-free, it burns hot enough to replace combustible fossil fuels, and when it combusts it leaves behind nothing but water vapor — a seeming silver bullet for the clean energy industry. Not only can it be used to replace things like coking coal, which wind and solar can’t replace because of the ultra-high temperatures needed , green hydrogen could also be a key component to scaling up other clean energies by providing a green method of storing energy that doesn’t require things like lithium-ion batteries, which in turn rely on finite rare Earth metals and minerals . There are already plenty of industries that rely on burning hydrogen and have done so for years, but that doesn’t make them clean, because hydrogen is only as green as the energy that is used to make it. The vast […]
