Important Step Taken Towards Energy Hub North Sea

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.”

The Netherlands Fossil Free in 2030

“A new world”. Dutch economist and politician Herman Wijffels about the necessity of a global sustainable transition.

There is pressure mounting in the Netherlands that the country should speed up the implementation of the Paris accords and EU energy policy of “Europe fossil free by 2050” and get the country largely fossil-free as early as 2030. The public financial position of the Netherlands is good (surplus) and there is broad popular support for the 2030 policy objective. And last but not least: there is a large commercial advantage if you are able to offer energy services to the rest of a world-in-transition. The idea is to influence the program of the new government, the formation of which is yet underway.

Dutch Island Ameland Energy Independent in 2020

Ferry to Ameland. Every Dutchman has positive associations with the island of Ameland. Ameland: that’s beaches, dunes, birds, holiday, cycling trips.

The ambitious mayor of Ameland wants to bring his island energy independence with solar panels, fuel cells, heat pumps, energy storage and bio gas. No wind turbines.

MegaWindForce Turbine

A rotating ring containing many generators rather than a traditional axis and single generator plus gear box. Turbine can be constructed with low weight carbon fiber, low maintenance and long life span.

A company in Winschoten, the Netherlands, patented a new wind turbine design, with which it claims it can generate the same amount of electricity with lighter wind turbines with a rotating ring rather than an axis, causing enormous wind forces to be absorbed by a larger surface, enabling lighter design. Under offshore conditions a Megawindforce turbine of 135 m tip height would generate the same power as a conventional 200 m turbine. Additionally the new turbine design is supposed to begin to generate energy at lower wind speeds by gradually switching on ever more generators inside the ring with increasing wind speed. Because of this variable load principle the turbine can operate at lower rotational speeds which lowers the forces, enabling a staggering 80% reduction of the overall weight and proportional lower cost.

Cost claim: 3 cent per kWh.

A prototype is being built in the Groningen province this year, financially supported by Groningen authorities.

2016 Was a Bad Onshore Wind Energy Year


The windindex (windex) of Yard Energy Group.

Wind parks in the Dutch province of Gelderland didn’t do very well in 2016 as there was 20% less wind in the province, the 3rd or 4th worst wind year in a century. And the first months of 2017 weren’t very good either. On a positive note 2015 was a good year.

Solution: go offshore.

Thermo-Acoustic Heat Pump

ecn-thermal-accustic-heat-pump

The Dutch national energy bureau ECN has build the prototype of a heat pump that is smaller than conventional heat pumps and potentially could become even a lot smaller. What is special about this heat pump is that it operates on sound. Sound is a pressure wave. If air is compressed it gets warmer. The ECN heat pump is a closed tube with speakers.

Core parameters: heat pump is a wall-mounted box of 40x50x10 cm. You need electricity for an air pump and speakers. Electricity of 1 kWh returns 4 kWh of heat. Air is pumped from outside and led through the (inaudible) “sound heat pump” and finally pumped into the living space, providing ventilation as an extra.

Within the Dutch context that means that you get the same heat performance from 2 kWh (40 cent) as from 1 m3 gas (64 cent). Eventually that heat pump can be powered by electricity from renewable sources. The heat pump should cost ca. $1,000 including installation.

[wikipedia.org] – Thermoacoustic heat engine

At [1:00] the sound-heat conversion is demonstrated. Sound in the tube pumps heat from lower to higher temperatures.

The thermo-acoustic principle in reverse: use heat to generate standing sound waves and create mechanical work.

Dutch Rail Runs 100% on Wind Power

Roger van Boxtel, the CEO of the Nederlandse Spoorwegen (Dutch Rail, DR) could be persuaded to pull a stunt and let himself be tied to a wick of classic Dutch wind mill to promote the point that as of January 1, DR is for 100% powered by wind energy.

The international dispersed wind parks obviously don’t really power the locomotives of DR, but what DR did was subsidize the construction of sufficiently wind power, matching their own electricity demand. In end effect it doesn’t really matter, since Europe has an interconnected grid. What DR did was giving the good example to other corporations to do the same and as such give themselves a well deserved green image and help realizing the renewable energy transition.

Offshore Wind 40% Cheaper By 2023

flow

The Dutch national energy bureau ECN says that by 2023, the cost of offshore wind energy could be reduced with 40%. Way to achieve this:

  1. Technological innovation, like larger rotors and larger distance between turbines (15%)
  2. Design improvement, wind-park layout, logistics (6%)
  3. Efficiency project developer (10%)
  4. Cooperation between wind parks (10%)
  5. Optimization organisation & (capital) cost (3%)

This would mean that the price of our virtual barrel of oil equivalent, calculated here, would be reduced to $6/barrel (if that wind energy is applied for mobility purposes).

Dutch Post-War Electricity Production

nl-electricity-production

Studying this graph could give cause to a somewhat relaxed attitude regarding doom stories related to a so-called “energy crisis”. The kicker: in 1945 there was hardly any electricity production in the Netherlands worth mentioning. If you project the current level of “decentral” generated electricity (wind, solar, bio, hydro, etc. and fossil based electricity and heat production by private parties other than power stations) onto the past, you arrive at 1970. Life was already pretty good in those days. There is no reason to assume that society would break down if for some reason electricity production would be reduced substantially.

nl-electricity-production-source

Not to give the impression that “decentral” is the same as “renewable” (dark blue). It isn’t and there is no reason to be complacent. But once these offshore wind GWs are installed after 2030 there is no reason to despair with the Dutch energy situation as far as electricity is concerned. Space heating is a different story. Solution approach: seasonal storage of solar heat and most of all geothermal.

Gold Mine North Sea

continentaal_plat[source] Partitioning North Sea

A considerable part of Dutch wealth since 1960 was based on the natural gas field in Slochteren, once the #9 gas field in the world. That gas field is now running on empty. So what’s going to happen to the Cloggies and their wealth? Dire poverty? Not so fast.

Post-stamp country Holland measures 42k km2, think Kentucky. Its share of the North Sea however is larger: 57k km2… and has the potential to become the Dutch new energy province, replacing Slochteren and the coal mines of the Limburg province, closed down in the seventies.

Let’s make some simple back-of-the-envelope type of calculations to get an idea of the potential of this new energy province.

LED-Lights in Greenhouses

Passengers approaching Amsterdam Airport from the SSW at night will observe an orange glow over a large area, originating from greenhouses in the Westland area, SW of The Hague. This is going to change though as growers replace conventional lighting with pink-colored LEDs. The energy bill can be halved with this measure.

Construction Started COBRA Cable Netherlands-Denmark

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.
