Hibernating freeze-thaw molten salt batteries for seasonal energy storage
Preface. A 100% renewable grid can’t happen without long-term energy storage. Today that’s done with natural gas (with a little help from hydropower in the 10 states that have most of it). Meanwhile nuclear and coal chug along at a … Continue reading
Hydrogen hopium: green hydrogen from water
Additional energy consuming steps not shown: pumping water to the electrolyzer, purifying the water, compressing or liquefying to -423 F, pumping into storage container, the trucks to deliver H to stations costing $75 million each, since pipelines are super expensive … Continue reading

Why wind and solar will cause more blackouts
Preface. Clearly fossil fuel plants need to be replaced with energy storage — batteries, pumped hydro, or compressed air. Many hours of backup power will be needed since, unfortunately, over two-thirds of total wind power in the U.S. happens outside … Continue reading

Utility scale energy storage doesn’t scale up: limits to minerals and geography
Preface. 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. And … Continue reading
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

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
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

Challenges to the Integration of Renewable Resources at High System Penetration
Preface. This overview of challenges for wind and solar written in 2010 is still true today. We are far from being able to reach even a 50% renewable grid (excluding hydropower from the total) given the lack of storage, 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
