Storage costs are dropping rapidly. New batteries are nearly there for cost competitiveness. As the first generation of BEV batteries become 'spent', they will be reused in grid-scale applications. Space and weight are not a concern, and most will have ~70% of their original capacity. That accelerates quickly once Gen 2 batteries have hit end of life.
- macspoofing 7y ago>Storage costs are dropping rapidly Read around, nobody actually believes Li-ion batteries can bridge the intermittency gaps of solar and wind. The production capacity may never be there and cost aren't there today and may never get there (cost for US to store 10-15% of excess summer energy to use in winter with Li-ion batteries would run tens of trillions of dollars). Li-ion batteries leak energy if you want to use them to store excess power for weeks (as you would have to). That's the problem. There isn't a battery technology now, or forthcoming.
