Arsted is moving forward with a plan to grow corals in wind turbines

In addition to natural beauty, corals play an important role in the natural world. According to the National Oceanic and Atmospheric Administration, a quarter of sea fish depend on healthy corals.

The Danish energy company Arstet plans to try to grow corals at the bottom of coastal wind farms to see if the system can be implemented on a large scale.

The concept of “Taiwan’s tropical waters” will be tested in collaboration with Taiwanese partners. This week’s news reflects the latest step in the company’s recall, which restarted in 2018.

Last year, those involved in the memory were able to grow young corals in a quasi-site. These were grown in what Arstead called “underwater samples and concrete substrates.”

Feedback trials in June 2022 include an attempt to establish larvae at the Greater Sangua 1 offshore wind farm in waters 35 to 60 kilometers (22 to 37 miles) off the coast of Taiwan and then grow corals. The project will use areas of 1 square meter on four foundations.

In a statement on Wednesday, Orsted said the project’s goal was to “determine whether coral reefs can be successfully grown in coastal wind turbine foundations and to evaluate the initiative’s potential positive impact on biodiversity.”

With their obvious beauty, corals play an important role in the natural world.

According to the National Oceanic and Atmospheric Administration, a quarter of sea fish depend on healthy corals. “Fish and other creatures find shelter in many coral-shaped depressions, find food, breed and breed their young,” says the American company.

As a source of food and so-called “new medicine,” NOAA says, coral reefs provide coastal protection against erosion and storms and provide employment to communities.

Despite their importance, the planet’s coral reefs are rapidly threatening, including coral reefs. In March, the Great Barrier Reef Marine Park Authority in Australia, which manages the Great Barrier Reef Marine Park, confirmed the fourth mass-bleaching incident since 2016.

According to GBRMPA’s 2017 fact sheet, corals are put under pressure, and the smallest photosynthetic algae – called zooxanthellae – are removed and bleached when the famine begins.

“When zooxanthellae leave the corals, the corals become pale and become more and more transparent,” it says.

The fact sheet on power lists the most common causes of bleaching as “constant heat stress, our climate change and the frequent occurrence of ocean warming”.

Corals can recover from bleaching if conditions change and they can die if conditions do not improve.

Ørsted, for his part, argues that water temperatures in wind farms further from the coast provide more stability, and describes “high temperature rises” as “vertical mixing in the water column”.

The superficial idea of ​​the recall project is that this stability at water temperature will limit the potential for coral bleaching, allowing for healthy coral growth at the turbine foundations.

The wind turbines’ interaction with nature – including the sea or birds – will be part of the most important debate and debate in the future, both on the coast and at sea.

In April, the US Department of Justice announced ESI Energy Inc. He pleaded guilty to three counts of violating the “MBTA” or Migrant Bird Contract Act.

In more detail, the US Energy Information Administration has stated that some wind projects and turbines can lead to bats and bird deaths.

“These deaths may contribute to a decrease in the population of organisms affected by other human-related influences,” it said.
