It seems like the next major energy invention we need is long-term storage. Batteries have gotten much more cost effective, but you still need to amortize their costs over hundreds of charge-discharge cycles to get a payback. They're too expensive to store summer energy for the winter.

If you had an energy storage technology that could store energy with a very low storage cost, even if it were very inefficient, you could make use of the massive coming excess of summer solar power.

> A controversial energy project in south central Washington is one step closer to breaking ground. A federal commission released its final environmental review for the Goldendale Energy Storage Project — to the consternation of several tribes and environmental groups.

> The project is part of a potential solution to one of the biggest problems for renewable energy development: the variability of wind and solar. As the Northwest transitions off fossil fuels, power will need to be stored for when the sun doesn’t shine, and the wind doesn’t blow.
