I'm not sure long term storage will ever make sense since the capital costs are amortized across far fewer cycles. Once a year rather than once a day means 365x

I'm not sure long term storage will ever make sense since the capital costs are amortized across far fewer cycles. Once a year rather than once a day means 365x the capital cost. Instead over-provisioning of green generation and increasing grid capacity (to avoid risk of local week long lulls in generation) seems a much better bet.
