What this article needs is someone numerate who can at least do an order-of-magnitude estimate of the costs and benefits. When operating at scale, what will the marginal cost in terms of battery wear-and-tear be for storing 1 kWh and returning it to the grid? And how much will that storage be worth in terms of the difference between daily high and daily low electricity prices? Very frustrating that a putatively semi-technical publication like Electra doesn't even attempt this, or ask their interviewees estimates.
