The US department of Energy (DOE) have created an excellent free resource for all those who work in the energy sector and for those with an interest in energy.

The database currently holds information on over 420 active energy storage projects around the world. The database which is the first of its kind and a much needed resource for the energy industry details information on grid connected energy storage and relevant policy information and support data.

I would recommend taking a look at the database as it provides an excellent overview for the interested individual and more in-depth information for industrial experts. At a glance you can see the number of active projects superimposed on a map of the world, by zooming in you can increase the amount of information on each of the projects, from a brief description through to rated power and current status.

Project owners are encouraged to add to the database, each project submitted is carefully vetted for accuracy and relevant information by a team responsible for maintaining the database.

The database was launched in January 2012 and is already being cited in many reports, papers and interviews. At the moment 34 countries have registered projects, detailing information on over 50 different energy storage technologies, from battery technologies right through to magnetic energy storage and hydroelectric technologies.

As interest, funding and research activity grows in this area, database managers expect the number of entries to continue to rise, making this an indispensible resource for experts and the general public alike.
