When you float the basic system of a preliminary model Marine winds The turbine arrived at a berth in the Servourt, whoOn April 11, the engineers at Maine University were ready to add a tower and turbine and put him standing on his feet in Maine. The initial model, called Volturnus+, was a 1: 4 scale model for 15 megawatts, and will only put its second publication. Wind turbines To float in American waters.
But on the same day, university officials received a message from the US Department of Energy Advanced Research Projects Agency – Energy ((Arpa-eIt said that it is the “suspension of all activity” remaining on the $ 12.6 million project grant. This step left Hall concrete, which was 375 tons, and bound Durkside and its creator, defending the situation.
Volturnus+ is one of the many marine wind projects that have been delayed or killed in US Since the opening of President Trump II. On him The first day is to return to the officeTrump has signed an executive that freezes all the permits for external wind projects, affecting almost everything that was almost not being constructed. In an unprecedented step, the president froze on April 16 to work on one beach Wind farm This was already built from the New York Coast, before the demand was withdrawn last week.
In response, wind developers retreat from American projects. multinational Wind giant Rwe Temporarily Work on its American portfolio 6 GB entirelyQuoted from the “political environment”.
Disorders The destroyer may be particularly established for floating wind projects such as Voltunus+. Floating turbines Designed to work beyond the beach In the very deep water to consolidate the turbine towers on the sea floor, the emerging industry has not installed one commercial turbine in American water.
Trump’s effect on floating external winds
Its headquarters Mitsubishi Company In March, he temporarily stopped what the United States could be first: floating 12-turbine, 144 MW. “Research Safar “Plan 50 kilometers east of Portland, Maine. The company cited” the recent transformations in the energy scene, which in particular caused uncertainty in the marine wind industry. “
Maine policy makers depend on Mitsubishi Search Arm To develop jumping in floating winds and thus the state insurance Transmission And enhancing coastal economies. These small floating matrices act as a test to help cancel Gigawatt risks on the scale of upcoming projects and provide an opportunity to interact with stakeholders. “He – she“It is important because technology is still relatively immature,” he says. Steve CleimerThe Director of Energy Research in the Union of Primible Scholars. “YouYou should start somewhere in showing technology, searching for effects on the fishing industry and WildlifeHe says:
actually, Developers of a floating demonstration project in California, KadimoHe was closely watching Maine’s progress. andLoating turbines is the only sea wind option in the Pacific coast due to its deeper water.
In response to the Federal Wind Development opposition, supporters of floating technology take a variety of strategies. For Voltunus+ team, huge leaving He says a concrete platform linked to a platform that was not safe and financially destroyed, Habib DagherExecutive Director of Min University‘s Advanced center and vehicles In Orono and Voltunus+ coach. “You will destroy the sidewalk if you got the weather. We were paying fees to stay on the sidewalk – we cannot even carry it,” he says.
It has been prevented from reaching more than $ 3 million in the ARPA-E grant, the Dagher team collects enough Criticism from industry partners and state funds to do what to do: the tower and turbine companion to the platform, then withdraw the package to the planned test site about 600 meters off the coast of Castin, Maine. This was the only applicable option, says Dagher. “We had no choice but to find emergency money to get it out of there,” he says.

to MitsubishiThe challenges seem more widespread than the American political climate, and the international bloc responds by hitting the temporary stop button. In February Temporarily Three traditional wind projects abroad in JapanQuoting “material changes in the macroeconomic environment”, including the war in UkraineLow yen, and narrow supply chains.
California, however, press. In February, California Governor Gavin New Roosome suggested an investment of $ 228 million to prepare ports to build a wind farm abroad in the next decade. In March, California granted $ 20 million to Long Beach Port and $ 18 million to Humelt Port to strengthen General participation The required studies are conducted to view the permits files.
“they“Do not withdraw the money that has been previously allocated to the marine wind. They say” they adhere to the cycle. ” SimonsClimate Lawyer of the Environmental Protection Information Center, a non -profit organization based in ARCATA, California.
Of course, California can do a lot except without federal cooperation. Kadimo demonstration On the central coast of California, hope to sell its power to the Vandenberg base for the nearby space. They also need a green light from the National Administration for Oceanic and Atmospheric A national marine haven has been appointed In October, Cademo extends.
What are the following steps for Voltornos+?
Maine’s Volturnus+ Floating is a follow -up to the much smaller Voltunus test, which was a semi -familiar set of floating beams and float columns. In making Voltunus+, Min University simplified the design to reduce the cost – it is mainly a wardrobe located on top of the water. On their own, the Paraleg is less stable, but Dagher says that his team made the design in practice by inspiring it from the large parties that affect the tall buildings to address Earthquakes. “You deny some of earthquake He explains, “The suggestions by moving the bloc back and forth to oppose the earthquake movements.”
In the case of Voltunus+, the mass turns within each of bodyCrusher weapons converge the winds of wind and waves. based on Patent file 2023This mass can be sea water. Reduce the resulting stability from the required bottle. Besides the relative ease of construction, the design changes reduced the platform costs by 20 to 30 percent, says Dagher.
A comment message aria-e to the University of Maine claim a “Failure to comply with federal policies or more.” When asked to comment on this, a spokesman for the Arpa-E was referred range To the United States Ministry of Energy ((Antelope), And the Ministry of Energy did not deter rangeinquiry. The university says it is “compatible with all governmental and federal laws, and the conditions for granting them and federal contracts.”
Thanks to the emergency money, Voltunus+ Test Rig is now in 21 meters of water. The next step for the project leaders is to install a power cable linking the turbine to the wild network – a project that they hope to complete within two months to three months. Dagher says that the turbines will work for 18 months, as planned, to assess the stability of the platform. But in a statement submitted to rangeThe university says that without the resumption of Arpa-E boxes, researchers will have a lower ability to analyze the results and formulate the marketing plan.
Min University It was announced in mid -May that it would lead to nine people In the advanced structures in Dagher and Vehicles The center, citing “a temporary stop and delay in federal financing.”
