How is California’s AB2514 experiment with utility scale battery storage coming along?

[ This is an excellent article by Tod Kiefer about tests of sodium-sulfur batteries, which are the only kind of battery for which there is enough material on earth to make. Battery electric storage is meant to “replace nimble, fast-ramping … Continue reading

Heavy-duty hydrogen fuel cell trucks a waste of energy and money

[ Fuel cells are seen as an alternative to batteries, because batteries may always be too heavy to move trucks: Battery electric trucks (BEV) may never work out. Even if 5 to 10 times as much battery energy density (Wh/kg) … Continue reading

Utility scale energy storage batteries limited by materials and few locations for pumped hydro, compressed air

[ Natural gas is finite, but aside from (pumped) hydropower, natural gas is the main way wind and solar are balanced now. Therefore, a tremendous amount of energy storage will be needed in the future as natural gas declines. The … Continue reading

Who Killed the Electric Car?

[ Who cares about electric CARS?  Civilization ends when trucks stop running, and trucks can’t run on batteries because they’re too heavy (93% of the cargo weight, 25% of the cargo space), and an all-electric truck fleet would require thousands … Continue reading
