Here are some more facts for those assembled here:
1) Carbon Dioxide levels have risen from 325 ppm to 417 ppm in the 50 years I have been around - that is nearly 30% and the rate of increase is still getting faster
2) Climate change is real and undeniable, get over it
3) The energy transition is possible due to massive reductions in price of PV panels and wind turbines
4) ALL human sources of electrical energy are intermittent, even nuclear power stations are only available around 75% of the time. When they go do it is sometimes planned maintenance and sometimes unplanned.
5) Energy storage is necessary to balance fluctuating power demand with fluctuating power supply. In the past electrical grids only had one option for energy storage - hydroelectric, which is fine if you live in the wiggly bits like Norway but not if you live in the flat bits.
6) Fortunately battery storage has come on hugely and at just the right time. Lithium ion batteries are light and good for cars. But they burn and are needed for cars, so Vanadium flow batteries are the best solution for stationary energy storage
7) Vanadium is more earth abundant than Nickel, Chrome, Zinc and Copper but we mine it at a rate of only 1/100th the rate of those other metals. We didn't have any reason to mine it any faster before - but we do now because Vanadium flow batteries only need a single metal to operate and that is Vanadium
