The government has done something right! In contrast to the Obamacare website debacle, the DOE has provided a website that provides extensive and useful information on large scale electric storage projects.
The recent press release states,
" The Energy Storage Database lists 420 energy storage projects from 34 countries with a combined 123GW of installed capacity. More than 50 energy storage technologies are represented worldwide, including multiple battery technologies, compressed air energy storage, flywheels, gravel energy storage, hydrogen energy storage, pumped hydroelectric, superconducting magnetic energy storage, and thermal energy storage. The policy section of the database shows 18 federal and state policies addressing grid connected energy storage, from rules and regulations to tariffs and other financial incentives."
I've referred to in the past and used it to track storage projects. It's been useful to weed out the "vaporware" projects, like the Obama Stimulus Ashlawn project (not in the database) from the real projects. You can find our vanadium flow battery project at Gills Onions here.
It's a good resource - use it!
