DONG Energy of Denmark has won the bid for building the largest offshore wind park to date (1.4 GW), Hornsea-2 in the British part of the North Sea at a record low price guarantee of £57.50/MWh and is scheduled for completion in 2022. DONG is currently working on Hornsea-1 (1.2 GW), to be completed in 2020.
Earlier today the Dutch company Gasunie has joined the North Sea Wind Power Hub Consortium. The aim is to build an artificial “energy island” in the middle of the North Sea, where wind power to the tune of 100 GW will come together eventually and distributed to countries neighboring the North Sea. Furthermore the participating partners (Netherlands, Germany and Denmark) are serious about producing hydrogen and store it in empty gas fields under the North Sea.

The world’s largest wind turbine manufacturer Vestas wants to add storage facilities to its wind farms, hence the new relationship with battery manufacturer Tesla. With an ever increasing installed base of wind power, with a supply of electricity that is inherently variable, storage is becoming increasingly important.
Tesla wants to expands its customer base and move beyond car batteries and home powerwalls.
In a move that could be interpreted as a clear sign of confidence in its own renewable energy strategy, Denmark’s Maersk sold its oil and gas division A.P. Moller-Maersk A/S to French oil giant Total. Three months earlier the Danish company Dong Energy (Danish Oil and Natural Gas) sold its North Sea oil and gas production to German-based Ineos AG. Dong apparently wants to concentrate on its offshore wind core business.
Currently Denmark produces 40% of its electricity from renewable energy and plans to achieve more than 50% in 2020. Paradoxically Denmark would not be a major player in offshore wind without the experiences gained in offshore oil first. It looks like Shell is going down the same path.
With the current alarming news coming in from the climate change front, the prospects for offshore wind look extremely good, especially in the North Sea, were 90% of the world’s offshore wind activities are centered. Only a sudden real breakthrough in the field of nuclear fusion could ruin the prospects for offshore wind business.

Mitsubishi-Vestas has launched its massive V164-9.5 MW offshore wind turbine, built on the V164 platform and capable of powering 8,300 U.K. homes. Motivation: lowering cost offshore wind. The design changes within the V164 turbine platform are minimal. One such turbine is already being tested at Burbo Bank Extension Offshore Wind Farm, United Kingdom.
Dimensions: 35-metric-ton, 80-meter blades. Hub height of 105 meters and a tip height of 187 meters. Nacelle 390-metric-ton nacelle, 20 meters long, 8 meters wide and 8 meters high.
Last December, the machine broke a world record for production by a single wind turbine when it produced 216 MWh of power in a 24-hour period. With a Danish kWh electricity price of 9 euro cent and 31 euro cent for private consumers, this is the equivalent of €19,440 c.q. €66,960. With current offshore price of 2 million euro per MW, implying 20 million euro for the V164-9.5 MW, this would mean that 300 days of consumer end price turnover would match the purchase price (not to be confused with payback period of course).

Transport and logistics company situated in Esbjerg, Denmark. Blue Water Shipping (BWS) began in 1972 as a two-man company, today it has 1500 employees and 60 offices world-wide. BWS does transportation of wind turbine parts onshore and offshore, but not the final installation.
The Maersk Connector is the next generation power cable installation vessel, specifically designed to transport and install large volumes of HVAC and HVDC power cable via its on-board 7000Te split capacity capacity duel concentric carousel. The vessel is available for the offshore interconnector and export cable markets, but can also work to the high standards demanded by the North Sea Oil and Gas Industry.
TenneT TSO B.V. (Netherlands), Energinet (Denmark) and TenneT TSO GmbH (Germany) today signed a trilateral agreement for the development of a large renewable European electricity system in the North Sea. This so-called ‘North Sea Wind Power Hub’ has the potential to supply 70 to 100 million Europeans with renewable energy by 2050.
This important step towards a broad consortium was taken in the presence of the European Commissioner for an Energy Union, Maroš Šefčovič. Mel Kroon, CEO of TenneT, and Torben Glar Nielsen, CTO of Energinet, signed an agreement aimed at investigating the feasibility of one or more ‘Power Link Islands’.

TenneT and Energinet, as well as any other parties that want to join, will spend a few years on investigating the details and potential of one or more Power Link Islands. If the TSOs decide to go ahead with the project, a Power Link Island could be developed by approximately 2035
Estimated size: 6.5 km2
Estimated cost: 1.25 billion euro

The island might feature power-to-gas as a storage technique to utilize high volumes of wind generation, said Rasmussen. The North Sea is home to a sophisticated network of gas pipelines, which could help bring wind-generated gas to countries around Europe.
“A part of this work will be to include power-to-gas technology and other storage technologies,” he said. “What, when [and] how much is what we will look into further. It is too early to go into details.”

In Denmark, officials have taken strides to minimize the effects of climate change by converting from fossil fuels to renewable energy sources like wind and solar power. Over the next 35 years, the country aspires to become the first nation on earth to run completely, including transportation, on clean energy. NewsHour Special Correspondent Lisa Desai reports.
COBRAcable (COpenhagen-BRussels-Amsterdam cable) is a planned 320 kV, 700 MW HVDC submarine power cable between Eemshaven, the Netherlands, and Endrup near Esbjerg, Denmark.
The cable will have a length of 325–350 km, and will be jointly owned by Energinet.dk and TenneT. Its purpose is to improve the European transmission grid and thus to increase the amount of variable wind power in the energy mix while improving the supply security. Its 700 MW capacity corresponds to an annual transmission capacity of 6.1 TWh
[wikipedia.org] – COBRAcable
The capacity of the cable, to be completed in 2019, would be sufficient to power a city like Amsterdam. The construction of the cable is a natural part of the strategy to move towards more renewable energy and the necessity to even out intermittent supply.
[source] Denmark: 75% onshore, 25% offshore
Last Thursday the wind conditions in Denmark were such that 116% of the wind energy demand could be met in the evening.
Denmark’s wind energy infrastructure wasn’t even producing (3.77GW) what it could (4.8GW). Excess electricity was exported to Germany, Sweden and Norway.
Denmark aims to generate 50% of its electricity needs by 2020, but could reach that target even earlier: installation of new capacity adds 18% per year.
Editor: other countries like Sweden, Norway and Canada have even higher rates of renewable energy production, but they achieved that with relative easy means: hydro-power thanks to mountainous terrain, where Denmark is completely flat. Denmark is one of the most successful implementer’s of renewable energy in the world.
