- Denmark’s energy islands will be a hub for transmitting wind-generated electrical power and making inexperienced hydrogen.
- The vitality islands will create a new electricity program that will be equipped to transmit offshore wind electric power over large distances.
- This posting is part of “The Fantastic Strength Changeover” series.
Denmark is developing two energy islands that could speed up Europe’s inexperienced transition.
The islands – which will consist of one particular artificial island in the North Sea and a single designed on the island of Bornholm in the Baltic Sea – will make wind strength and, in the future, inexperienced hydrogen energy.
The tasks signal a new, built-in solution to making renewable strength. Found 100 km from the Danish mainland, the synthetic North Sea island has the opportunity to source energy to numerous nations alongside Denmark, which include the Netherlands, the United kingdom, and Belgium – a scale which hasn’t been previously possible. As perfectly as contributing to the EU’s 2050 net zero goal, the renewable electricity source would lessen Europe’s reliance on Russian fuel.
Jacob Østergaard, professor and head of the Section of Wind Energy at the Technological College of Denmark, told Insider that the task is a “significant undertaking”.
“It truly is a completely new kind of vitality technique that we are setting up,” he additional.
A Danish innovation with implications throughout Europe
The North Sea island, which is established to cost €28 billion, will be manufactured up of a central hub produced of metal, concrete, and sand, and will be surrounded by a sequence of platforms and wind turbines. No just one will reside there permanently — but there may be accommodation for shorter stays for employees.
The Bornholm island will be on a very similar scale and could offer electricity to Germany and Sweden in the long term. For the 39,000 persons who live on the island, the challenge is welcome – a latest poll by a regional tv station observed that 85% of islanders are in favor of the challenge, which will consist of a enormous transformer station on the south side of the island and a network of wind turbines.
Klaus Vesløv, director of Public Affairs at Bornholm Vitality & Offer, informed Insider that although there has been some backlash to the measurement of the transformer station, the vast majority of islanders hope that the project will carry jobs and energy protection.
“Energy policy is also a security plan, in terms of not currently being reliant on Russian gas,” Vesløv explained. “This section of the discussion has really moved the [green] agenda bigger up.”
Renewable power is just not a new endeavor for Denmark – they have been the initially state in the planet to construct an offshore wind farm again in 1991. What’s unique about the energy islands, although, is the way that they will convert and transmit the electrical power that they make.
Most standard offshore wind farms transmit electricity directly to the mainland. Although interconnectors have facilitated some energy trade, the potential to share wind-generated electricity between nations around the world is presently confined. That means that surplus wind energy can at times go to waste.
Hanne Storm Edlefsen, director for Strength Islands at Danish electric power operator Energinet, which is foremost the challenge, told Insider that the electricity islands will be “innovative, technological stepping stones” in the race to build an built-in, higher voltage energy technique in the North and Baltic Seas.
“[The islands] will make it doable to harvest substantial quantities of offshore wind electricity and transmit it in excess of extended distances to decarbonize power use even in European international locations with confined or no coastline accessibility to the sea,” Edlefsen mentioned.
At 1st, the North Sea island will supply 3 gigawatts (GW) of electricity. Finally, it will have a capability of 10 GW.
The hub will house higher-voltage machines to collect and convert electrical power from alternating present to immediate existing. Direct present is in a position to transmit electric power around much greater distances.
Edelfsen explained that this innovation suggests that the vitality islands will be in a position to be designed a lot additional out to sea than classic offshore wind farms. It also means that the electrical power islands will be able to hook up with additional than just one place and power marketplace at a time.
Prospective for developing inexperienced hydrogen
The first islands could be little by little extended to establish an offshore grid infrastructure with multiple hubs, according to Østergaard.
“If you want to harvest electrical power significantly from shore it is significantly more successful to obtain the strength in hubs and then transmit to shore – in its place of several personal cables from each individual wind farm heading to shore,” Østergaard claimed.
He additional: “Denmark should really help Europe to satisfy this environmentally friendly transition and collaborate with all international locations all around the Baltic Sea and the North Sea.”
The moment entirely set up, Edlefsen advised Insider that the energy developed on the electrical power islands could also be utilised to deliver inexperienced hydrogen for sectors like hefty field, aviation, and shipping and delivery.
“The advancement of hydrogen is speedy-transferring,” Edlefsen reported. “Previously scientific tests demonstrate that offshore output of hydrogen and the transportation of hydrogen in pipelines on the seabed to the shores will be each possible and in some conditions economically feasible as in comparison to onshore production.”
Eco-friendly hydrogen could be in particular critical on Bornholm Island – all-around 60,000 ships pass the island every single year.
“Bornholm could develop into a bunker hub for those ships,” Vesløv instructed Insider. “We could make the most of individuals huge quantities of energy to turn them into inexperienced fuels [for shipping].” At the time accomplished, Bornholm Island will generate 6GW of electric power – adequate to power 7 million properties.
“The reality is nobody has finished this ahead of on this scale,” Vesløv said, adding that Denmark’s islands will be a “blueprint”.
“The entire world is heading to construct a great deal of electricity islands,” he mentioned.
