Nevada approves energy-storing train
By David Z. Morris, Fortune
One of the biggest challenges of the shift to renewable energy like solar and wind is energy storage.
The wind or sun don’t always generate power exactly when it’s needed, so infrastructure needs to bridge the gap. Batteries are the most frequently discussed solution, but there are other options out there, many of them surprisingly low-tech.
In April, the Nevada Bureau of Land Management granted environmental approval and a land lease to Advanced Rail Energy Storage (ARES), a startup with an energy storage solution that’s both novel and old-school.
