If that actually performs at the price quoted (1/10 Li ion) them I think we have the long duration storage needed to overcome diurnal intermittency. It still doesn't solve seasonal, but again, getting 50-95% there is better than not

I'm not saying to not build renewables, but you still require something else. You can't use batteries for a week in January when the wind is dead and solar is at near zero. You must replace coal capacity with gas in Alberta, there is no other choice. That's reality. Well, that or weeks of blackouts.
