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

How safe are utility-scale energy storage batteries?

Preface.  Airplanes can be forced to make an emergency landing if even a small external battery pack, like the kind used to charge cell phones, catches on fire (Mogg 2019). If a small battery pack can force an airplane to … 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

Why solar power can’t save us from the coming energy crisis

Preface. Embedded within the posts below are many reasons why solar electricity can’t replace fossil fuels.  All solar and wind do is add to the giant fire of burning fossil fuels with just a tiny bit more power, about 4% … 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 us?

Preface: The New York Times had two articles about zinc air batteries in September 2018.  Right now, finite natural gas is the dominant way of balancing unreliable, outright missing, or intermittent power from wind and solar.  So other energy storage … 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

How are energy storage batteries coming along? U.S. House hearing 2015

[ My favorite quotes from this U.S. House of Representatives session: THOMAS MASSIE, KENTUCKY. I want to say this has been a very enlightening hearing, and it confirms my personal experience, which is batteries are not sexy. Buckets of acid … Continue reading

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

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
