More Offshore Wind Proposed For New Jersey | Earth Wise

September 13, 2023 By EarthWise Leave a Comment

There have been three offshore wind projects previously approved by utility regulators in New Jersey. New Jersey is vying to become an East Coast leader in the fast-growing offshore wind industry and now developers have proposed four new projects off the New Jersey Shore.

Two of the projects would be located far out to sea where they would not be visible at all from the shore. One of them, called Community Offshore Wind, would be built 37 miles offshore from Long Beach Island. It aims to generate enough electricity to power 500,000 homes.

A second project, called Leading Light Wind, would be located 40 miles off Long Beach Island and would consist of up to 100 turbines that would generate enough electricity to power 1 million homes.

The two companies that are building the already-approved Atlantic Shores Wind Farm have submitted a bid for a new project located 10 to 20 miles offshore. In addition, a fourth application to the New Jersey Board of Public Utilities has also been submitted, but there is yet no public information about it.

Existing offshore projects have drawn intense opposition from homeowners in part because they are close enough to the Atlantic City and Ocean City shorelines to be seen by beachgoers, albeit as tiny objects on the horizon. The new proposed projects located far offshore would not have this problem.

The new projects can take advantage of existing federal tax credits, but the bidders say they will not seek the tax breaks from New Jersey that the earlier project received as they have also been the subject of legal challenges by opponents of offshore wind.

Floating Turbines For Offshore Wind | Earth Wise

June 18, 2020 By EarthWise Leave a Comment

Offshore wind is big in Europe. There are more than 5,000 offshore wind turbines across 12 European countries with a total capacity of more than 22 gigawatts. Almost every one of those turbines sits on a long tower sunk into the seabed and bolted into place in places where the water is 60 to 160 feet deep.

But off the coast of northern Scotland, there is the Hywind Wind Park which has five 574-foot-tall turbines located 15 miles offshore where the water is 300 feet deep. The giant masts and turbines sit on buoyant concrete-and-steel keels that allow them to stand upright and float on the water like a giant buoy. The giant cylindrical bases are held in place with mooring cables attached to anchors that sit on the seafloor.

A key advantage of floating turbines is that they can access outlying ocean waters up to half a mile deep, which is where the world’s strongest and most consistent winds blow. Another advantage is that such turbines can be installed over the horizon, out of sight of coastal residents who might not like to have wind turbines visible in their scenic ocean views.

Floating wind power has enormous potential for contributing to the expansion of renewable energy. Offshore wind is still quite a bit more expensive than land-based turbines, and the cost of electricity from distant floating turbines is more than that from near-shore wind turbines. But all of these costs are likely to come down with improving technology and increased production volume.

There are real challenges to the expanded used of floating wind farms, but the promise of harnessing so much of the open seas for electricity generation is an attractive proposition.
