Our intern, Fabio Porcu asks: I’m writing about batteries but it’s a very large topic. Do you prefer that I write about the physics behind it, or about the different technologies used today? I think this should be broken down …
Recently, I ran across a company called ITN Energy, a top player in redox flow battery solutions that I thought I’d mention to readers, as they are well-poised to take advantage of the current global market demand in the energy …
A reader on Quora.com asks: When electricity is generated at a plant, is it stored and then distributed to the citizens? Can electricity be stored at such a large scale? How efficient is the storage process? A wonderful and comprehensive …
Simon Holege asks: Is compressed-air energy storage (CAES) a serious alternative to using batteries for wind farms, etc.? Under what conditions can CAES be regarded as a viable technology for large scale energy storage? I’ve been a believer in this …
