So many ways to store energy, once it's in a malleable electric form.
So many ways to store energy, once it's in a malleable electric form. Originally shared by Brian Slesinsky From the article: "[R]ail storage is faster, with lower capital costs, than its main rival in grid-scale storage, pumped hydro (which pushes water up and downhill just like ARES pushes slabs). It's also more scalable than pumped hydro — you can do it incrementally all the way from 20 MW to 3 GW — and can be located in more places. All it needs is some open land and a slope. Notably, it doesn't need water, which allows it to operate in the arid American West." http://www.vox.com/2016/4/28/11524958/energy-storage-rail
