Unfortunately the math is meaningless if it takes 10 000 years to get those 10 000 cycles. Batteries are currently competitive for short response times and short cycles. As price declines they become become useful for longer cycles, but there will be a point beyond which we need alternative solutions, such as bulk storage/gas, long transmission lines, and/or demand management.

In principle I prefer antipodal transmission lines for the grid and batteries for transport — grid is cheaper and a trade opportunity — but at global scale, such a grid will take a while to build.
