The technologies which enable long-term energy storage - from heat, to pumping water to manufacturing hydrogen. How will long term storage work and what will it cost?

Why Lithium-ion batteries and pumped hydro are the leading candidates for short duration grid energy storage. And why renewables electricity generation plus storage will be cheaper than fossil fuel electricity in a Net-Zero future.

From short-term energy storage to seasonal energy storage - how do we balance supply and demand in a Net-Zero future. Pumped Hydro, Batteries, Compressed Air, Gravity, Demand Response, Hydrogen and e-Fuels: the technology ready to take on the energy storage challenge.
