The challenge with energy storage is the tradeoff between cost and efficiency. On the one end you have batteries that are hella efficient but expensive, and then you have a spectrum going Hydrogen -> Pumped Energy -> Compressed Air (cheapest and least efficient) The question is whether we can build enough wind or solar power that doesn't just meet our needs when it's outputting well, but overshoots them by like 500% so we can use cheap and inefficient energy storage.
