Statoil has announced that a new battery storage solution for offshore wind energy will be piloted in the world’s first floating wind farm, the Hywind pilot park off the coast of Peterhead in Aberdeenshire, Scotland.

Batwind will be developed in co-operation with Scottish universities and suppliers, under a new Memorandum of Understanding (MoU) signed in Edinburgh on 18 March between Statoil, the Scottish Government, the Offshore Renewable Energy (ORE) Catapult and Scottish Enterprise.

Battery storage has the potential to mitigate intermittency and optimise output. This can improve efficiency and lower costs for offshore wind. The pilot in Scotland will provide a technological and commercial foundation for the implementation of Batwind in full-scale offshore wind farms, opening new commercial opportunities in a growing market.

Stephen Bull, Statoil’s senior vice president for offshore wind, says, “Statoil has a strong position in offshore wind. By developing innovative battery storage solutions, we can improve the value of wind energy for both Statoil and customers. With Batwind, we can optimise the energy system from wind park to grid. Battery storage represents a new application in our offshore wind portfolio, contributing to realising our ambition of profitable growth in this area.”

The pilot will be part of Hywind Scotland, an innovative offshore wind park with five floating wind turbines located 25 km offshore Peterhead. The wind park is currently under construction and start of electricity production is expected in late 2017.

Scotland’s Energy Minister Fergus Ewing says, “The signing of this MoU will allow the signatories to work together in the development of the Batwind battery storage solution. This will help maximise the renewable generation of the Hywind offshore wind farm, whilst informing the case for energy storage and demonstrating the technology’s ability to support renewables in Scotland and internationally.”
