Here’s a piece on a subject we haven’t talked too much about recently: energy storage. In this case, it’s analogous to pumped hydro (see left) or advanced rail energy storage, both of which take off-peak energy and use it to …

Flywheels as Energy Storage
It’s been a while since we’ve discussed converting off-peak electricity to kinetic energy and storing it with the use of flywheels. Linked above is a start-up that claims to have breakthrough technology in this space. And indeed, breakthroughs will be …
Pumped Hydro Energy Storage
From a reader: Connecticut’s largest lake (Candlewood Lake) is really a 100-year-old hydroelectric facility. Water is pumped from the Housatonic River through a gigantic tube and into the lake, where the water is stored until it’s needed to generate electricity. …

Hydrogen Is Problematic, But Not for the Reason Discussed Here
Here’s an article that suggests that our civilization’s use of hydrogen as an energy carrier can result in higher concentrations of greenhouse gases. They claim that fugitive hydrogen combines with certain atmospheric compounds (though they aren’t specific about this) that …

Discussion with a Clean Energy Skeptic
A reader who is skeptical of the value of renewable energy writes: No wind? No electricity. No sun? No electricity. True. Both solar and wind are variable energy resources, which introduces a problem for grid-operators who are trying to integrate …
Installing Solar Panels? Here’s Why You Should Hold Off on Battery Storage
When President Biden took office, he developed a sustainability-driven policy aimed at minimizing ecological harm. The Build Back Better plan highlights a national carbon-neutrality goal to reduce greenhouse gas emissions. Support for the project involves developing a clean electric grid. …

Hot Rock Energy Storage
Here’s a piece on “hot rock” energy storage, where tanks of tiny stones, the size of peas, are heated to as much as 600 degrees C when energy from intermittent sources like solar and wind exceeds demand. How this could …
Tesla Powerwall Rival Seeks to Bring Hydrogen Into Your Home
2GreenEnergy super-supporter Gary Tulie writes: Hi Craig, Re something like this, I have to ask what’s the point? The hydrogen energy store is 3 times the price of a Tesla Power wall to store 3 times the energy, so about the same …

The Mysterious Eos Zinc-Air Battery
I met the people from Eos at an energy storage event in San Diego many moons ago, perhaps 2010. One of their reps told me that they were right around the corner from a commercially available zinc-air battery that would …
Cheaper Energy Storage?
Here’s an article that discusses the UK’s massive plans to replace fossil fuels with renewable energy and storage. All well and good, until the author heads in the direction of vehicle to grid (V2G), the two-way flow of electrical energy …
