Hydrogen is likely to play a crucial role in our efforts to wean ourselves off fossil fuels, but making it in an environmentally friendly way requires huge amounts of water. Now researchers have developed a new technique that makes hydrogen fuel out of thin air in even the driest climates.
While renewable energy and battery technology are making big strides in decarbonizing large parts of the power and transport sectors, hydrogen could also be an important part of the energy mix. It can be burned just like conventional fuels, but the only byproduct it releases is water. It has decent energy density, which makes it a promising solution for applications with stringent weight requirements like aviation, and it can also be a useful way to store energy over longer periods.
But how eco-friendly hydrogen fuel is depends a lot on how it is produced. Today, the bulk is so-called “grey…
