Hydrogen leaked into the atmosphere from pipes or storage tanks indirectly acts as a greenhouse gas, but there are still significant climate benefits to be had if we switch from burning fossil fuels to burning clean hydrogen.
When burned, hydrogen emits only water vapour and heat. If produced with clean energy, hydrogen fuel offers a carbon-free way to power processes that are difficult to run on electricity, such as steel-making. As such, it is seen as an …
