Its a decent effort, but to put 4GWh in perspective: my small house requires about 10MWh in heating over the winter. I can reduce that with a heat pump by a factor 4, but that till means the storage is only enough for about 1800 homes.
We need a PWh+ of storage, and we need it in the next decade, and we are nowhere near on schedule.

Very few people need seasonal storage, most people are on a grid connected to somewhere closer to the equator: https://en.wikipedia.org/wiki/Wide_area_synchronous_grid
All of Europese, far starters.
