Intermittent wind, solar, and wave power can not replace fossil fuels and nuclear power electricity generation without energy storage

Renewable costs don’t include transmission & energy storage backup from Nat Gas & Coal plants

Preface. Wind and solar advocates don’t include transmission and backup costs in their net energy and cost calculations. But without fossil backup, the electric grid will come down due to lack of storage. There is almost nowhere left to put … Continue reading

EV cars and utility scale energy storage batteries are not likely to materialize

Preface.  Clearly there’s not enough minerals and metals to shift from fossil fuels to electric vehicles and utility scale battery storage, due to peak critical elements, peak platinum group elements, peak precious elements, peak rare earth elements, and peak everything … Continue reading

Natural Gas essential for energy storage

Preface.  The U.S. Department of energy has admitted that a renewable grid is impossible without long-duration storage (LDES) and plans to hand out half a billion dollars to commercialize (LDES) (Colthorpe 2022).  Another recent report also argues that round-the-clock renewables … Continue reading

Concentrated Solar Power is dying out in the U.S.

Preface.  Concentrated Solar Power (CSP) contributes only 0.06 % of U.S. electricity, mainly in California (64 %) and Arizona (24 %) because extremely dry areas with no humidity, haze, or pollutants are required. Of the 1861 MW power they can … Continue reading

How safe are utility-scale energy storage batteries?

This 2 MW battery, installed by the Arizona Public Service electric company, exploded in April 2019 and sent eight firefighters and a policeman to the hospital (Cooper 2019). At least 23 South Korean lithium-ion facilities caught fire in a series … Continue reading

Gravity energy storage

Preface. This is interesting, but not commercial. And as my book “When trucks stop running” explains, trucks are the basis of civilization, and can’t run on electric batteries or overhead wires. Even if they could, I explained why a 100% … Continue reading

Pumped Hydro Storage (PHS)

Preface. This is the only commercial way to store energy now (CAES hardly counts with just one plant and salt domes to put more in existing in only 5 states). Though of course hydropower is only in a few states … Continue reading

Utility scale energy storage has a long way to go to make renewables possible

What follows comes from my book “When Trucks Stop Running: Energy and the Future of Transportation” , which is also where you’ll find the references backing up what I’ve written below. I often get letters from people about energy breakthroughs … Continue reading

Can Zinc batteries save the electric grid?

Preface: Right now, and as long as natural gas lasts, the electric grid will stay up since it is the main storage and way to balance unreliable wind and solar power. Hydropower can also play a major role in the … Continue reading

Underground pumped hydro storage is the only technology capable of massive storage for renewable electricity

[ Picard concludes that “None of the candidate technologies for massive-scale renewable and sustainable generation of ‘‘green’’ electricity deliver it in a form suitable for high-efficiency storage. None of the prospectively-massive storage modes for transformed electricity is at present well … Continue reading
