Plans to install turbines on platforms that float in the sea are gathering pace as renewable energy developers seek new areas to harvest wind power.

Scotland has granted planning permission for as much as 92 megawatts of floating offshore wind capacity, including two separate projects in the past two weeks. In Ireland, the developer Gaelectric Holdings Plc and Ideol SAS, a French floating wind company, agreed on Friday to develop floating wind projects in Irish waters, starting with a 30-megawatt array.

The deals bring to about 237 megawatts the capacity of floating offshore wind projects that will be installed worldwide by 2020, according to Bloomberg New Energy Finance. Thats just a fraction of the 38,000 megawatts of turbine due to be fixed to the seabed by the end of this decade.

Floating wind has the potential to bring clean energy to island nations that might not have much land and the seabed is too deep for normal offshore wind, said Tom Harries, Bloomberg New Energy Finance.

The nascent technology is seen as key to cutting the costs of offshore wind power and opening up swathes of seabed that would otherwise be undeveloped because of poor seabed conditions or because its too deep.

In Scotland, developers are rushing to meet a deadline to get the only subsidies available for floating offshore wind farms before they have to compete with other cheaper renewables. In order to get that support, floating projects must show theyre on track to produce first power by the end of September 2018.

The projects recently approved in Scotland both target deep waters that would otherwise require massive concrete or steel structures to anchor turbines.

Recent projects include:
