450GW Offshore Wind by 2050 in Europe Realistic

WindEurope has made an inventory of the offshore wind energy potential in European waters. Summary: 450 GW in 2050 is realistic. Note that the average EU electricity consumption is ca. 300 GW. As a rule of thumb, to achieve complete decarbonisation, one needs to double the current electricity consumption, or 600 GW (rough estimate).

Japan & US Ready to Construct First Offshore Wind Farm

Better late than never.

Japan has issued a call for developers interested in building and operating a floating offshore wind farm off Goto City, Nagasaki Prefecture.

The scale will be modest, at least 16.8 MW.

The US already has a small offshore wind park near Rhodes Island (“Block Island”, 5 turbines, 30 MW). This time, a small demonstration wind farm is being built in federal waters for the first time, by Orsted-Denmark and Jan de Nul-Belgium, 43km off the coast of Virginia Beach.

Danish Investors to Finance North Sea Energy Island


The Chinese have built artificial islands in the South China Sea for geopolitical/military reasons. The Europeans are about to build energy islands in the North Sea, to collect electricity from the North Sea, potentially turn it into hydrogen and distribute the renewable energy to consumers in the riparian states Netherlands, Germany, Denmark, Norway and Britain.

A consortium including three of the largest Danish pension and energy companies is ready to finance and operate the recently approved energy island in the Danish North Sea.

Denmark Presents 18 GW Offshore Wind Map

Denmark has made an inventory of places in the North Sea and Baltic where offshore wind parks could arise. Total potential power: 18 GW.

Additionally several so-called energy islands have been designated in both seas, both existing and artificial new ones. And since the intended capacity is larger then Danish electricity needs (4 GW), power lines will be installed to the Netherlands and Poland.

VattenFall Will Use 11 MW Turbines for Next Windpark

Vattenfall has given the green light for yet another “largest offshore wind project in the world”, in casu “Hollandse Kust Zuid” (“Dutch coast south”), 1.52 GW. Project completion date: 2023.

New is that 11 MW turbines will be used, rather than the 9.5 MW turbines applied in the Borssele project.

Siemens-Gamesa 11 MW turbine, currently tested in Osterild, Denmark. Will be used to construct Hollandse Kust Zuid.

Timeline Dutch Offshore Wind Development 2020-2030

The Dutch Court of Audit has calculated that currently the installation price of offshore wind has declined to € 1500-2000 per kW or € B1.5-2.0 per GW.

De Algemene Rekenkamer onderzocht ook de oorzaak van die prijsdaling. Die komt vooral door verlaging van de bouwkosten per geïnstalleerd vermogen, die is van € 2500-3000 per kW zijn gedaald naar € 1500-2000 per kW. Dat komt door de plaatsing van grotere en verbeterde windturbines, dalende staalprijzen, betere samenwerking tussen de betrokken bedrijven en gunstiger leenvoorwaarden.

Electrolysis Part of HKN Tender

Danish company Ørsted will have to compete with the consortium CrossWind consisting of Shell and Eneco for subsidy-free construction of the Hollandse Kust Noord (HKN) offshore wind project (760 MW). Shell and Eneco announced their participation in the bid yesterday. The winner of the bid will be announced within 3 months time.

What is radically new in the world of offshore tenders is that both Ørsted and CrossWind hint at their readiness to invest in electrolysis capacity as well, as part of the overall bid, even if this technology is not yet profitable. The wind park builders recognize that in the long term it is no longer sufficient to throw intermittent electricity on the market, it needs to be buffered as well. Enter the hydrogen economy, officially backed by the Dutch government.

From the Shell announcement:

Shell and Eneco are participating in the tender for Hollandse Kust (noord) through their joint venture CrossWind… Together with the large-scale development of offshore wind projects comes the challenge of intermittency in wind generation. That is why CrossWind will invest in various innovations that can be implemented at full-scale in future wind farms to help balance the electricity network and keep societal costs low… If the current plan will materialise, the hydrogen plant on the Tweede Maasvlakte will be built on a site especially designated by the Port of Rotterdam (2 GW conversion park) with Shell as the launching customer. In this plant, green hydrogen will be produced through electrolysis… The hydrogen plant will have a capacity of around 200 MW… Shell intends to start operations by 2023 to produce about 50,000 – 60,000 kg of hydrogen per day. The green hydrogen produced will initially be used at the Shell refinery in Pernis to partially decarbonise the production of fossil fuels. This saves a minimum of 200,000 tonnes of CO2 per year. It is important that as of 2023 there is enough green hydrogen available, which can be used to decarbonise trucks in the transport sector directly. This way, approximately 2,300 hydrogen trucks per day could run on this volume of green hydrogen as the market for trucks on hydrogen further develops… Through the connection of this wind farm to our possible future green hydrogen plant in the Port of Rotterdam, we want to develop a new value chain together with our partners and governments – from wind to hydrogen – to create a green hydrogen hub. We regard this as a stepping stone for the recently announced NortH2-project. These projects fit well with our aspirations to provide more and cleaner energy to our customers”… The green hydrogen plant that Shell wants to realise fits perfectly in the role that the port of Rotterdam envisions for itself to build a public hydrogen network in the port area. “Shell’s announcement is now accelerating our plans for the construction of a hydrogen pipeline for the Rotterdam industry,” says Allard Castelein, CEO of the Port of Rotterdam Authority. “With projects like this, we are jointly building a sustainable port and industry. This is important for the future of the port and therefore for the earning power of the Netherlands.”

Shell just kicked of the Dutch hydrogen economy for real.

Several Subsidy-Free Bids in for Hollandse Kust Noord Project

[source] “HKN” = “Hollandse Kust Noord”

The Hollandse Kust Noord offshore wind site consists of two parts (693 MW and 760 MW), located 18.5 kilometres off the west coast of the Netherlands. Several undisclosed bids have been offered to the Dutch government, none will require any subsidy. Orsted had announced earlier it would participate.

Floating Vessel Crane Collapse

Set-back for the offshore wind installation industry. A German-made crane (Liebherr), mounted on a Chinese-made offshore wind installation vessel, owned by the Belgian-based DEME Group, collapsed in the German harbor of Rostock during initial load tests. The ship was about to begin the construction of the 950 MW Moray East wind farm in Scottish waters. The exact cause is yet unknown.

Still Enthusiasm in the Dutch Market to Build Offshore Wind Parks Without Subsidy

While the first turbines of the 1.5 GW offshore wind park Borssele I-V already have started to produce electricity and the remainder is expected to be completed by 2021, is the Dutch government busy with planning for the next step, namely “Hollandse Kust Noord” of at least 700 MW. Fortunately there is still plenty of enthusiasm in the market to build the wind park without a dime public money. The names were not disclosed but probably Shell, Orsted, Eneco and others aspire to do the work and make money from selling the renewable electricity on the Dutch market after construction.

Earlier Vattenfall won two tenders for wind park “Hollandse Kust Zuid”. Construction will start in 2022.

Average Dutch electricity consumption is 13 GW. The overall aim of the Dutch government is to achieve 11 GW offshore wind by 2030. By that date, combined with onshore wind, solar and biomass from a potent agricultural sector, the Netherlands will be well underway to achieve the renewable energy transition as far as electricity is concerned.
