Wind energy taking flight offshore? Could offshore wind power be the upcoming major player in the renewable energy sector?
In the pursuit of a greener future, floating wind power is emerging as a potential game-changer. However, recognition from governments, utilities, and financiers as a viable technology remains the biggest hurdle to its full-scale rollout.
Europe, currently producing only 5% of the wind power supply that the International Energy Agency (IEA) and the EU say Europe should reach by 2050, is already leveraging offshore wind farms in the North and Baltic Seas to significantly increase clean energy production. These farms have driven down their price per kilowatt to market-competitive levels.
The ocean space beyond the reach of conventional offshore turbines constitutes 80 percent of the world's ocean space. Enter floating wind power, with its giant masts and turbines sitting in buoyant concrete-and-steel keels, held in place by three taut mooring cables attached to anchors on the seafloor. The floaters, or floating wind turbines, can access vast swathes of outlying ocean waters, up to half a mile deep, where the world's fiercest and most consistent winds blow.
The WindFloat Atlantic project off Portugal's coast is a testament to this potential. This floating wind power station is capable of producing enough power to supply 60,000 homes. France, too, has floating wind power written into its clean energy plans and aims to be the world leader in this technology.
Countries with current plans for floating offshore wind farms in deep sea areas include South Korea and Japan, which are planning floating centers and platforms, respectively. China is advancing rapidly with underwater infrastructure concepts. The U.S. states on the Pacific Ocean are prime locations for floating wind parks, according to Walt Musial, an offshore wind energy expert at the National Renewable Energy Laboratory.
However, some critics doubt that the high costs of floating wind power will ever come down enough to rival onshore wind and solar energy. The price per kilowatt of generated electricity from floating wind power isn't currently competitive on energy markets, similar to conventional offshore wind ten years ago. Moreover, floating wind power stations have shorter lifespans due to the corrosive nature of the marine environment.
Despite these challenges, experts like Frank Adam, an expert on wind energy technology at Rostock University in Germany, view floating wind turbines as a technology that heralds a powerful new generation of renewable energy. Wind energy of all types, including floating wind power, figure prominently in the European Union's plans to go climate neutral by 2050.
A YouTube video showcases a floating turbine in a storm, demonstrating its resilience in harsh conditions. The future of floating wind power seems to be a stormy one, but one that promises to bring about a brighter, more sustainable world.
