“Coming 10-15 Years Offshore Wind Will Be Booming”

Key figures power production The Netherlands

Average power consumption: 13 GW
Total power capacity: 29 GW
Size coming generation turbines: 8 MW nameplate power
North offshore capacity factor: 50% nameplate power

In other words: the Netherlands needs to install 13 GW / 8 MW / 0.50 = 3250 offshore 8 MW wind towers.
Modern jack-up vessels like the Aeolus (see video below) can install a single wind tower per 24h.
In other words, the energy transition of the Netherlands can in theory be accomplished within 10 years with a single jack-up ship. Dutch companies have several of these ships operational.

The bottle neck is not installing the monopiles but storing the generated wind power and convert it into H2 or NH3.

Ground Drilling Vertical Heat Exchanger for Heat Pump

Realistic price calculation:

Freestanding house: 750 m3
Two-three drilled wells of 85 meter each in the garden, 6 meter apart
Temperature cold side: 12 degrees centigrade
Project size: two men, one day
Energy saving: up to 70%

[aardwarmtepompen.be] – Average price tag:

Average residence, 8 kW heat loss and average geology, boiler 300 liter en floor heating 160 m2
Average space heating cost with natural gas for Dutch house-hold: 1,000 euro.

All-in prices for single household:

Soil-water heat pump with vertical heat exchangers: 20000 € excl. VAT
Soil-water heat pump with horizontal heat exchangers: 17000 € excl. VAT
Air-water heat pump: 14000 € excl. VAT
Subsidy: 1600 euro in 2018

Prices likely come down if you increase project scale. New homes will have no choice as proposed new regulation will forbid a natural gas connection for new-build homes. For the typical Dutch terraced houses, investment costs are lower.

[eigenhuis.nl] – In the Netherlands there are 7 million households. Of these 160,000 do own a heat pump. Currently this number increases with 20,000 per year. As per 2021 this number will increase as all new buildings by then will be deprived of a connection to the existing natural gas grid.

Dutch Energy Figures

Dutch electricity supply. Currently almost all electricity consumed is produced in the Netherlands. The plan in accordance with the EU is to replace almost all fossil generated electricity by renewable power by 2050 at the latest.

Electricity consumption: 120 billion kWh/year
Electricity per capita: 7085 kWh/year
Total installed capacity: 31.5 GW
Average consumption: 13.7 GW
Total connections: 8 million

Capacity factor latest North Sea wind farms: 50%
Assuming no storage losses then you would need 27.4 GW offshore nameplate wind power to meet current Dutch electricity demand levels. By 2023 4.5 GW are expected to be installed in the North Sea. Already allocated but not all covered with tenders yet are:

Borssele: 2064 MW
Hollandse Kust: 7350 MW
IJmuiden Ver: 7020 MW
Waddeneilanden: 1200 MW
Total: 17.5 GW

No fixed time table for these 17.5 GW exist, but if the first 4.5 GW are realized in 2023, you can expect that new capacity will be built with existing offshore production capacity in at least the same pace or higher. Since we already have 1 GW installed, the remaining 4.5-1=3.5 GW would take 5-6 years or 640 MW/year. The remaining 17.5-4.5=13 GW would require an additional 13/0.64=20 years or 2043 with existing installation capacity. In reality the offshore wind industry is rapidly growing and the targeted 17.5 GW will be achieved earlier, probably much earlier. Expect that by 2050 the Netherlands will enjoy the renewable energy consumption enabling them to continue the current affluence levels and will have created new large wealth creating industries in the energy and storage sector. Note that these figures do not include existing or future wind and solar capacity onshore.

After that the sky is the limit because the offshore industry could sell a lot of electricity or its hydrogen derivative abroad. Expect NW-European offshore wind industry like Vestas, Orsted (Dong), Siemens, SiF, Van Oord and many others to take over from big oil names like Gazprom, Exxon, Texaco, BP, Shell and many others. Or as president Gorbachev uses to say: He who comes too late is punished by life.

The good news is that in 2018 corporations are competing to develop offshore wind parks without a dime of subsidy, neither for the infrastructure nor for the kWh’s brought onshore. Paying market prices for kWh’s brought onshore is enough for them to be profitable. All the government has to do is allocate offshore locations and pay for the cables.

[renewablesnow.com] – Vattenfall to bid in Dutch subsidy-free offshore wind tender

The only remaining challenge is storage, a considerable one, but manageable. It is likely that hydrogen from electrolysis is going to play a big role here.

17.5 GW nameplate power would mean 8.8 GW continuously or 64% or 2017 electricity demand. That would be enough to uphold a reasonable affluent society. It would be like living in 1980, albeit with electricity consuming devices (lights, television, fridges) that are far more energy efficient. But it is far more likely that by 2050 more than the current 13.7 GW average consumption will be brought onshore, providing electricity for trains and e-vehicles as well. The Dutch train system is already fully covered by wind. And here a calculation that you need merely 222 wind turbines of 6 MW each to power the entire Dutch personal car fleet.

According to new legislation, every home in the Netherlands needs to be energy neutral by 2030. No natural gas connection will be guaranteed for new homes. This requires solar panels, thermal collectors, heat pumps and thorough thermal insulation measures. It is ambitious but feasible.

[energynumbers.info] – Capacity factors Danish offshore wind farms
[noordzeeloket.nl] – Dutch plans North Sea Wind (map)
[rijksoverheid.nl] – Bedrijfsleven bereid zonder subsidie windpark op zee te bouwen

P.S. the goal of the Dutch government is to have 6 GW wind power installed onshore by 2020.

Sites with lower capacity factors may be deemed feasible for wind farms, for example the onshore 1 GW Fosen Vind which as of 2017 is under construction in Norway has a projected capacity factor of 39%. Certain onshore wind farms can reach capacity factors of over 60%, for example the 44 MW Eolo plant in Nicaragua had a net generation of 232.132 GWh in 2015, equivalent to a capacity factor of 60.2%, while U.S. annual capacity factors from 2013 through 2016 range from 32.2% to 34.7%.

Let’s assume a capacity factor of 50%, that would mean that another 3 GW continuously (including not yet installed storage) are added to the mix as early as 2020.

And then there is solar:

[hollandsolar.nl] – Marktontwikkeling zonnestroom
[goedkopeenergieengas.nl] – Opbrengst zonne-energie groeit met 40 procent

Summary: by the end of 2016 there was 2.0 GW peak Watt PV-solar installed, which translates in 800 MW power continuously. By the end of 2017 the installed power had increased with 40%. So we can assume 1.1 GW of PV-solar power. The government wants solar panels on every suitable roof and the public is picking up the signal. In every street there are at l east a few houses that have panels on the roof, which will impose the question on the laggards: “when us?”, just like with owning a car or having an internet connection. Nobody wants to stay behind and everybody wants to be “green”. One of the largest energy providers in the Netherlands Eneco believes that as early as 2030, 70% of renewable electricity can be covered by renewables.

Energy Island(s) North Sea Taking Shape

After TenneT TSO B.V. (Netherlands), Energinet (Denmark), TenneT TSO GmbH (Germany) and Gasunie (Netherlands), it is now the Port Authority of Rotterdam that is backing plans to build one or more wind power hub islands in the middle of the North Sea, starting from 2025. This is significant as the Port Authority has broad experience in acquiring new land from the sea. These hubs could play an important role in realizing the intended 70 GW to 150 GW offshore wind power in the North Sea by 2040. Adhering to the Paris Accords, 180 GW needs to be installed in the North Sea by 2045. Every energy island should collect 10-30 GW and transport the energy via connectors to the Netherlands, Germany, Denmark, Norway and Britain.

The second use of these socalled Power Link Islands is the production of hydrogen via power-to-gas conversion installations and brought onshore via existing pipeline infrastructure. And thirdly, large converterstations in the middle of the sea would no longer be necessary. And finally, these islands could function as maintenance hubs for nearby wind parks.


Converter platforms like this one soon superfluous?

Printing Solar Cells

Solliance from Eindhoven, The Netherlands, wants to mover away from standard solar panels towards thin film solar and apply those to surfaces like cars, windows, curved building surfaces or even glasshouses:

They are close to printing cheap roles of hundreds of meters of solar thin film cells, with a conversion efficiency of 12.2-13.5 % on the basis of perovskites.

World Primeur – Lagerwey Self-Climbing Crane in Action

As of now, large wind turbines can be assembled without the need for the usual external giant cranes. Instead the wind tower under construction can be used itself as a crane. this reduces the cost of wind turbines construction considerable. The Lagerwey L136-4.5MW costs 4,5 million Euro if constructed conventionally. By applying the self-climbing crane, cost reduction amounts to “several hundreds of thousands of euro” over the total cost of the wind turbine.

Additionally it is now possible to install a wind tower at hard-to-reach places, like mountains ridges or dikes. Old school cranes require a transportation effort of 150 truck trailers, the self-climbing crane merely three. Additionally it is no longer necessary to prepare the ground for the weight of large eternal cranes. Installation cost self-climbing cranes: 20% of the conventional installation cost.

Dutch Company Comes to the Rescue of US Offshore Wind

America has an archaic protectionist law called the Jones Act from 1920. The law says that transport between two American harbors can be done only with American-built ships with an American crew. This law effectively kills US offshore wind development before it gets a chance to be born, because America, as an offshore wind developing nation, doesn’t have the equipment to install offshore wind parks. Offshore wind technology is world-wide for more than 90% a North-West European affair, with installation vessels and crew all-European. European offshore installation in American waters violates the Jones Act.

The US has currently only one “windpark”, Block Island near NYC: 5 turbines with a 30 MW capacity, build by Europeans. When the Norwegian shipping company Fred Olsen crossed the Atlantic, the installation ship was not allowed to dock in a US harbor. This is not good for US offshore wind.

Now a Dutch company GustoMSC has come up with a simple design that can be constructed and operated by Americans and as such start the long overdue offshore wind development near the US coasts.

The Growing Importance of IJmuiden as Offshore Wind Hub

The Netherlands, currently the bottom of the barrel in Europe as far as installed renewable energy is concerned, has ambitious plans to change that. The port of IJmuiden, 15 km West of Amsterdam. wil play a central role in building more than 14 GW of offshore wind power in the coming years.
