New and improved grid-scale energy storage technologies are gaining popularity. Pumped hydro storage is efficient, but installations are expensive and time-consuming to build. Lithium-ion batteries are common in small applications, but building large-scale lithium-ions remains prohibitively expensive. Ultracapacitors and flow batteries have their niche uses. And some cutting-edge solutions aggregate many small amounts of storage, whether from electric vehicle batters, uninterruptible power supplies, or the thermal storage embodied in water heaters. Scroll down for insight into this important sector.

Practical, cost-effective energy storage is one of the holy grails in the smart grid sector, but the way different regions approach solutions is very different. In Asia, notably China, universities are heavily relied on for R&D contributions, unlike Europe and the Americas, says a new report from Lux Research.

We've worried that utilities are giving too much of their operations away to outside companies that handle renewables, energy efficiency and other programs for them. So we were glad to see that a Montana electric cooperative is taking a different approach. Click for details on Flathead Electric's customer partnership on energy storage.

We call storage the game-changer and we bemoan the high cost of batteries, pumped hydro and other techniques. A story on a new electric "storage heater" introduced in the UK has us wondering why the electric power industry isn't doing more with thermal storage.

As this video details, PG&E is on the forefront of testing applications for smaller-scale storage such as batteries. The utility recently deployed a two-megawatt sodium-sulfur battery pilot project at its Vaca Dixon substation to test potential applications of energy storage on the grid. is also installing a four-megawatt battery at the end of a distribution feeder in San Jose, to test applications including improving service reliability and power quality to customers.

There's always a lot going on in the smart grid energy storage field, primarily driven by the need for grid-scale storage to handle increasing amounts of renewable energy and in smaller form to provide better, cheaper batteries for EVs. We thought you might be interested in some current storage projects, technologies and thinking, some of which admittedly sounds a little crazy.

This report by the Pacific Northwest National Laboratory attempts to estimate the market size for stationary energy storage systems for two specific applications: 1) balancing services necessary to accommodate the growing variations in the generation supply from renewable energy resources, and 2) energy arbitrage that provides congestion management strategies and the potential to lower the cost of delivering electricity.

The California PUC this week made what some say is a "monumental" decision to order Southern California Edison to procure at least 50 megawatts of energy storage by 2021 and to consider storage as a "preferred source" in its resource mix. Could this be the breakthrough storage has needed?
