Britain Explores Vast Offshore Wind Potential with Floating Turbines

In a groundbreaking move towards achieving its net-zero emissions goal by 2050, Britain is turning to floating turbines to harness the remarkable wind speeds found further out at sea. Pioneering this technology, developers like Cerulean Winds plan to install floating structures up to 200km off the Scottish coast, overcoming the limitations of conventional seabed-fixed turbines. While costlier to install, floating turbines can generate significantly more energy, making them a crucial element in the UK’s strategy to achieve 100 gigawatts of offshore wind power by mid-century.

Cerulean Winds aims to have its initial 600-megawatt phase operational by 2028, contributing to the country’s transition to cleaner energy. The technology not only opens up vast new areas offshore but also plays a pivotal role in supplying clean electricity to North Sea oil and gas platforms.

Two key events in the coming year will shape the future of this sector. Firstly, a government subsidy round is expected to attract bids for pilot schemes, expanding on the two small demonstrator projects operational off Scotland. Simultaneously, the Crown Estate plans the first commercial-scale floating wind auction in the Celtic Sea, off southwest England, further marking the significance of floating offshore wind as a new frontier.

While the UK currently has only two small floating wind pilot projects with a combined capacity of 80MW, representing a fraction of traditional wind turbines, it holds a substantial share in the global capacity from floating turbines. Equinor’s Hywind, the world’s first floating offshore wind farm operational since 2017, has been a success with a capacity factor of 54%, outperforming the European offshore wind average.

Despite these successes, challenges lie ahead, including lengthy planning processes, slow grid connections, and the need for port investments to handle the large equipment required. To mitigate risks, the Crown Estate is offering a 50% discount on option fees for delayed projects, emphasizing the importance of maintaining the UK’s global leadership in floating offshore wind technology.

Industry experts, including Equinor’s Halfdan Brustad, foresee floating offshore wind as the new era, considering its potential to harness wind resources in previously untapped areas. The upcoming government subsidy contracts and the Crown Estate’s auction are crucial steps in propelling Britain towards becoming a commercial powerhouse in floating wind, fostering investor and supply chain confidence.
