Here’s another variation on the theme of storing off-peak energy by pushing a mass uphill, and then releasing the mass when energy is needed.  Think of it as pumped hydro without the hydro. This has an advantage over competitive ideas …

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 …

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. …

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 …

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 …

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 …
