Ørsted and ATP, along with their partners Aarsleff, Bouygues Construction and Van Oord, presented their modular energy island concept for the upcoming Danish North Sea tender.
Nordsøens Energiø (North Sea Energy) Island will be an island under constant development even after construction, the developers said.
In the spring of 2021, Ørsted and ATP joined forces to develop “an innovative and sustainable concept” for the energy island in the North Sea.
Ørsted, ATP and their partners aim to create an ever-evolving island, an evolving project where there will be unlimited space for innovation and adaptation as the green transition unfolds.
The energy island in the North Sea consists of a small island with dam which can be expanded with flexible modules.
Modules can be added and replaced as needed. The modules are built on land and connected to the North Sea energy island, so the island can easily be upgraded to connect more than 10 GW offshore wind, which is the current ambition from Denmark, the developers said.
The island can also be adapted to accommodate the rapid development of Power-to-X and other technologies in 2030 and 2050.
“We are ready to deliver an island that embraces the rapid development of green technologies and enables rapid scaling of the green transition,” Rasmus Errboeregional manager for Ørsted in continental Europe, said.
“The North Sea energy island will be more than just an island. We believe that our modular concept offers the best conditions for the energy island to be relevant in 2030 and 2050, and we look forward to further dialogue with authorities and decision-makers about the North Sea energy island. .
Developers see flexible modules as the most scalable solution and a direct way to deliver large amounts of green power as quickly as possible.
The modules can be built on land, at the same time as the dammed island and the offshore wind turbines are built at sea, which should save a lot of time during the construction phase.
“We believe that the flexibility of our concept is a great advantage and creates a very good climate-friendly energy solution.” Claus Winbladdeputy director of the ATP, said.
“It’s absolutely crucial when you’re embarking on a long-term investment like this. The foundations are in place to create a reasonable risk-adjusted return, and at the same time we are investing in the green transition. In this way, Nordsøens Energiø matches both ATP’s climate ambitions and the goal of creating the best possible pensions.
With the flexible and modular concept, Ørsted and ATP estimate that the energy island in the North Sea can provide green electricity two years before an inflexible and dammed island.
“With this concept, we have taken known technologies and construction methods and brought them together in a new, smart and revolutionary way suited to the harsh environment of the North Sea. This means that we can give the Danes a energy that can ensure huge scaling up of offshore wind, which from the outset is ready for future needs,” Jesper Kristian JacobsenCEO of Aarsleff, which leads the consortium of entrepreneurs for the North Sea energy island, said.
