Alstom, Voith and Gridflex have half the energy storage market. Well, 48% of the world’s total storage capacity to be precise, says Navigant Research, and that’s from what it describes as the “measureable market”. According to the company’s Energy Storage Tracker 3Q13, Alstom has 19%, Voith 16% and Gridflex Power 13%.
Another dozen large vendors, including Toshiba, Allis Chalmers and Hydrodynamics Group control the other 52%. A conclusion of the report is that there is a steady increase in energy storage projects worldwide, with North America and Asia leading the pack.
There are key differences between the development of the two regions, however, with the East concentrating on battery exports and the West concentrating on government funding of innovation in the field, generally. As a result, says Navigant, North America tends to have a far more diverse range of technologies aimed at becoming viable energy storage.
