Energy Storage: Batteries and Hydrogen
What do we do when the wind doesn’t blow and the sun doesn’t shine?
The world is transitioning to renewable energy at record speed, and energy sources such as wind and solar power are a key part of this green revolution. However, this also creates new challenges: How do we store the energy for when we need it, if we cannot produce it continuously? And how can we store electric power densely enough that the transport sector can benefit from it?
Three out of four new cars sold in Norway in 2023 were electric, and we currently have more electric vehicles per capita than any other country. Electrification of the transportation sector is a key step in the green transition, but it depends intimately on advances in materials science.
Lithium-ion battery technology has enabled an electric revolution for everything from power tools to personal vehicles. Hydrogen is also an essential part of the green energy transition. For this to continue also with long-haul trucks, freight trains, grid-based energy storage, maritime shipping and aerospace transport, new energy storage technologies are needed.
