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.

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.

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.
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 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. Projects IJmuiden Ver and Hollandse Kust (“IJmuiden Far” and “Dutch Coast” resp.).
Overview subsidized renewable energy projects in the Netherlands to the tune of 5.8 billion euro. Half of that amount went to solar projects. The other half mostly to wind, biomass and some geothermal.

Available data World Solar Challenge 2017:
Nuna Solar Team TU Delft: 3021 km, 14:10:41, average speed 81.2 km/h
Solar Team TU Eindhoven: average speed 69 km/h, 6 charges, 10197 person-km, 45.7 kWh external energy, average passengers: 3.4, energy efficiency (person-km/kWh) 223.2
Note that the external energy was necessary due to the long distance of 3021 km in merely 6 days. If the available time would have been 12 days, no extra electricity would have been required. In other words, the daily range without external (grid) charging (but “24h” solar charging) under Australian conditions in October would be ca. 250 km with 5 persons.
Eindhoven btw drove with 5 persons until a major technical malfunction occurred, after which no risks were taken and a single driver-passenger completed the race alone, which pressed down the passenger average. If you offset these 250 km with a daily average distance of merely 37 km in an industrialized country like Holland, you can verify that an energy-autonomous car is not a pipe-dream at all.

In a global trend of the world’s 50,000 largest ships moving away from relatively dirty fuel oil towards LNG, Royal Dutch Shell has introduced the South-Korean built Cardissa, a vessel able to refuel ships at sea with LNG and as such provide more flexibility. The future of LNG in shipping looks bright since the global acceptance of the Paris Accords. Heavy fuel oil is one of the dirties fuels around, due to its sulfur content.

Pictures from Schiedam harbor near Rotterdam. The 900 tons crane of the offshore wind jack-up vessel Aeolus is being replaced with a 1600 tons one to prepare the ship for installation of heavier 8 MW wind turbines. Investment volume 300 million euro. The ship is playing an important role in getting the planned 4.5 GW offshore wind capacity installed by 2020 (Germany 6.5 GW and UK 10 GW by 2020). The Aeolus is able top operate in water depths of up to 45 m. The crane adaption has to be made only 3 years after the ship was commissioned, illustrating the rapid pace with which the offshore wind sector is developing and subsequent price decline.
In 2016 the Dutch government was prepared to subsidize 12 cent/kWh, but Danish Dong offered to do it for 7.27 cent. Later Shell, Van Oord, Eneco and Mitsubishi/DGE were awarded the tender for Borssele III & IV for merely 5.45 c/kWh. In Germany tenders were awarded for wind parks to be built in 2024-2025 with no subsidy at all. Won’t be long until wind developers will be fighting over available offshore locations for the privilege of being allowed to build ever larger wind farms.
In 2017 technology has advanced to the tune that monopiles are installed with an 8 m diameter, 80 m long and weighing 1300 tons. Vestas and Siemens are building 8 MW turbines and the next steps towards 10-15 MW machines are being prepared. The Aeolus can install one foundation per day.

A second L136 tower will be built by the end of the year with a self-climbing crane (see video at the bottom), turning the tower in a self-constructing wind turbine.
Still waiting for this one to materialize:
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.

A wind tower is essentially a support structure to carry the nacelle and rotor. The wind turbine company Lagerweij conceived that a large crane used to build up the huge wind power structure is not necessary at all, but that the wind tower under construction can serve as its own crane. This reduces the construction cost of a wind turbine considerably. Additionally, more areas become suitable for placement of wind towers that were inaccessible for heavy cranes before, like dikes, mountain ridges or draughty terrain.
Giant cranes like the one here in Austria won’t be necessary anymore [1:29].
A team of the Dutch national news NOS traveled to the northern tip of Canada (68 degrees Northern latitude), that is Fort McPherson, to report about the visible effects of climate change. Note that both men are dressed in shirts (18-20 degrees Celsius), the environment is surprisingly green and there is no snow or ice and instead lots of mosquitoes. In the old days winter temperatures of minus 30-40C were normal, nowadays minus 20C is the new normal.

You can’t be a great power if you have no functioning efficient energy base. In the 20th century that #1 power was the United States and its oil-based economy. In the 19th century that #1 power was Britain and its coal and steam-engine. In the 17th century the #1 power was the Netherlands and its windmill-based economy. Thousands of windmills were used to pump water away to claim new land and sawmills produced the planks with which the Dutch could build a fleet of 30,000 ships, three times more than the rest of the world combined, used to set up a global empire and en passant to keep the English away.
The lesson for the 21st century is that again that political unit will be the geopolitical “top dog” who embraces a new energy base first. That energy base can only be a renewable energy base, born out of the necessity to combat fossil fuel depletion and climate damage. A united Europe is well-placed to be that political unit and the only one with a coherent renewable energy policy (“completely fossil free by 2050”), but China is taking renewable energy serious as well. And although Washington has no real renewable energy policy worth mentioning, on a state level, like Texas and California, successful initiatives do exist. It is too early for anyone to claim victory.
