World's First Floating Wind Farm Exceeds Expectations
The world's first floating wind farm only switched on three months ago but it's already performing better than expected—and that's despite a hurricane, a powerful winter storm and waves as high as 8.2 meters (27 feet).
The 30-megawatt Hywind Scotland, located about 15 miles off the Aberdeenshire coast, churned out 65 percent of its maximum theoretical capacity during November, December and January, according to its operator, Statoil.
In comparison, the typical capacity factor for a bottom fixed offshore wind farm is 45-60 percent during the same winter months, Statoil pointed out.
"We have tested the Hywind technology in harsh weather conditions for many years and we know it works," said Beate Myking, senior vice president of offshore wind operations in Statoil.
"It is very encouraging to see how well the turbines have performed so far. Hywind Scotland's high availability has ensured that the volume of electricity generated is substantially higher than expected."
These results show great promise for the emerging technology. As EcoWatch previously detailed, floating turbines have been deployed before, but mostly in small-scale projects, such as the 7-megawatt system built and operated by the Fukushima Wind Offshore Consortium. In contrast, the Hywind's five floating turbines produce 6 megawatts each on top of waters more than 328 feet deep. At full capacity, the facility can generate enough power for 20,000 homes.
As Bloomberg explained, typical offshore wind farms are installed on seabeds in relatively shallow seas. But with a floating system, countries like Japan, the U.S. West Coast, and the Mediterranean—where seabeds drop steeply off the coast—can also utilize the technology.
Statoil sees "great potential" to build more floating wind farms on top of waters around 200 feet in depth, even in areas with extreme environments and weather conditions. In October, the Hywind survived Hurricane Ophelia's 77 mph winds. It then faced even stronger winds in December, with Storm Caroline's 100 mph gusts and walls of large waves. Although the farm's wind turbines were shut down during the worst of these winds, they automatically resumed operations afterwards, Statoil said.
"Knowing that up to 80 percent of the offshore wind resources globally are in deep waters (+60 meters) where traditional bottom fixed installations are not suitable, we see great potential for floating offshore wind, in Asia, on the west coast of North America and in Europe," said Irene Rummelhoff, executive vice president for New Energy Solutions in Statoil.
The developers are looking to expand the technology and hope to reduce the costs of energy to €40-60 ($50-$75)/MWh by 2030, making it cost competitive with other renewable energy sources. The cost of onshore and offshore wind has seen significant reductions in recent years, with the UK's latest renewable energy auction dropping to 57.50 pounds ($76) per megawatt-hour, Bloomberg noted.
"This is an ambitious, but realistic target. Optimized design, larger and more efficient turbines, technology development and larger wind parks will drive down costs, improve infrastructure and logistics," Rummelhoff said.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
"There was a lot of devastation throughout the state," Governor Mike Parson said at a Thursday morning press conference, as NPR reported. "We were very fortunate last night that we didn't have more injuries than what we had, and we didn't have more fatalities across the state. But three is too many."
