UK energy storage manufacturer RedT has completed testing of a vanadium redox flow battery system to be installed on the Scottish island of Gigha.
The six week testing programme of the 75kW/1.68MWh system took place at the Power Networks Development Centre in Cumbernauld.
The London company will install by the end of the year seven 15kW/240kWh vanadium redox flow batteries to remove constraints on the island’s 1MW wind farm.
redT is designing and manufacturing energy storage systems from its engineering base in Livingston.
The company plans to create 30 jobs within the area by 2019, supported by a Regional Selective Assistance grant of £210,000 from Scottish Enterprise.
The storage technology will ultimately enter mass production in Scotland, it said.
Scottish energy minister Paul Wheelhouse said: “Our support for the company will allow it to continue to develop this important battery technology in its newly opened development, engineering and customer administration facility in Livingston.”
RedT chief executive Scott McGregor added: “We made the decision to base our manufacturing and design centre in Scotland due to the high quality of the Scottish workforce, Scotland’s excellent shipping links to the rest of the world and the support available from the Scottish Government and bodies such as Scottish Enterprise.”
