LONDON, June 9 (Reuters) – Global offshore wind capacity is set to quadruple over the next decade to reach 420 gigawatts (GW) ​by the end of 2035, a ‌report by the Global Wind Energy Council (GWEC) showed on Tuesday.

• Around 92 GW of offshore wind was installed by the end of 2025, enough to ‌power ​around 100 million homes.

• ⁠More than 327 GW ⁠of new offshore wind capacity is forecast to be added in the next decade, taking global offshore wind capacity to 420 ​GW by the end of 2035, the report said.

• More than 50 GW ⁠of offshore wind projects are ⁠currently under construction around the ​world. Annual installations are expected to double this ​year, triple by 2031 and surpass 50 ‌GW per year by 2035.

• China accounts for 52% of the global offshore wind market, having overtaken Britain in 2021. Germany, the ⁠Netherlands and Taiwan are also among the top five countries for offshore wind installations.

• “Offshore wind is ⁠a natural ‌fit for many countries but there ⁠are still too many solvable ​challenges ‌that are delaying more projects being ​built,” said ⁠Rebecca Williams, deputy CEO of GWEC.

• “The planning and grid connection process can be painfully slow and beset with risks for developers and investors,” she added.
