New Concept in Energy Storage
A huge percentage of the power grid was built solely to address peak loads, and is used less than 100 hours per year. This is one of the many reasons that energy storage in any of its forms is so …
From Guest Blogger Pooja Maharshi: An Advanced Steam Technology That Shakes The Steam Basics
Since the invention of a steam pump by Thomas Savery in 1698 steam has been used for multiple processes. Application have included pulling trains, creating electricity from nuclear plants, cooling with an absorption exchanger or simply heating liquid or air …
Making the Case for Affordable Grid-Scale Energy Storage
Those of us who concern ourselves with the challenges associated with integrating variable resources (solar and wind) into the grid-mix are paying close attention to developments in various battery chemistries, particularly those that invoke extremely common (and thus inexpensive) …

From 2GreenEnergy Intern Fabio Porcu: Sodium Sulfur (NaS) Batteries
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 …

From 2GreenEnergy Intern Fabio Porcu: An Overview of Energy Storage
Energy storage consists of a series of techniques and processes that allow one to concentrate different forms of energy to be used later; thus devices that store energy are sometimes called “accumulators.” Consider for a moment the concepts of potential, …
