A new battery storage solution for offshore wind energy is to be piloted in the world’s first floating wind farm, the Hywind pilot park off the coast of Peterhead.
The Batwind Battery project will be developed in co-operation with Scottish universities and suppliers, under a new Memorandum of Understanding (MoU) signed in Edinburgh between Statoil, the Scottish Government, the Offshore Renewable Energy Catapult.
Battery storage has the potential to support the deployment of wind energy by mitigating intermittency and optimising output to drive efficiency and lower costs. The Batwind pilot at Peterhead will provide a technological and commercial foundation for implementation in full-scale offshore wind farms, opening new commercial opportunities in a growing market.
Stephen Bull, Statoil’s senior vice president for offshore wind, explained: “By developing innovative battery storage solutions, we can improve the value of wind energy for both Statoil and customers.
“Through the Batwind concept, we can optimise the energy system from wind park to grid, applying advanced data analytics. Battery storage represents a new application in our offshore wind portfolio, contributing to realising our ambition of profitable growth in this area.”
Accordingly, Statoil will install a 1MWh Lithium battery based storage pilot system in late 2018. This equals the battery capacity of more than 2 million iPhones.
The pilot will be part of Hywind Scotland, an innovative offshore wind park with five floating wind turbines located in the North Sea about 15 miles off the Grampian coast. The wind park is currently under construction and expected to be commissioned in 2018.
Fergus Ewing, Scottish Energy Minister, added: “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.”
“A recent industry and Government report, produced by the Carbon Trust, concluded that if the energy market was adapted to appropriately recognise the benefits of electricity storage to the wider system, this could lead to savings of up to £50 a year on an average energy bill and a system wide saving of up to £2.4bn a year by 2030.”
