It could be a good way of dumping extra load in a renewable national grid. Spec the grid so that in low supply situations (low wind, low sun) there is enough power to cover actual demand 90% of the time. Then whenever there is extra power, (windy and/or sunny days) you redirect that extra power into carbon capture/sequestration.
