Wind Energy Storage: Offshore Batteries

By September 30, 2016Industry News

Statoil has launched a new offshore battery storage program called Batwind for their floating wind farm off the coast of Scotland. The floating windpark project is already innovative and groundbreaking in it’s field, the first floating offshore project globally. The five floating wind turbines will be located 25km offshore of Aberdeenshire, Scotland and are expected to be finished in late 2017. Investments of over two-hundred million euro have already been made in the project by Statoil. While the project is commissioned by Statoil, strong collaborative efforts will be made between Statoil, the Scottish Government, and surrounding universities. This project will not only create enough power for 20,000 households but also will bring 6,000 jobs during and after development to the area.

The Batwind energy storage project is hoped to improve efficiency and lower costs as well as reduce intermittency. Rather than risk the loss of excess or unused energy a single battery will be used to store the generated wind energy. “By developing innovative battery storage solutions, we can improve the value of wind energy for both Statoil and customers,” said senior vice president of offshore wind, Stephen Bull. To put the storage capacity in perspective, the single battery to be installed in 2018 will be a 1 MWh battery which has the same energy capacity as 2 million iPhones. Efficient energy storage has the potential to save £72 on individual energy bills per year, according a recent study by the Carbon Trust.

As the country becomes more aggressive about the sustainable development goals and cutting carbon emissions this development promises to be transferable on a global scale, “Floating wind represents a new, significant and increasingly competitive renewable energy source. Statoil’s objective with developing this pilot park is to demonstrate a commercial, utility-scale floating wind solution, to further increase the global market potential,” said VP for new energy solutions Irene Rummelhoff.
