NaS batteries are not new, but the application in industrial scale has taken place only recently, in the 1990s, by the Japanese. How do they work? Essentially they consist of two basic materials: the anode is made of liquid sodium …

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 …
Storage systems play an increasingly important role for renewable energy development in our modern society. Their primary function is to store energy produced from variable energy sources, i.e., those which, by their nature, are discontinuous since they are linked to …
