As Dr Cooley pointed out: “Electrons are really hard to store, and the best way of storing them is to turn them into a storable product. So, you end up changing the vector from an electron to a molecule – and then being able to store the molecule.” Hydrogen is also extremely versatile, making it possible not only to decarbonise areas like transport and heating where renewable energy has potential, but also to decarbonise industrial processes which cannot be converted to electricity. –Author: Ben Gallagher, Lead Analyst, Emerging Technologies at Wood Mackenzie
