The companies Engie, Colruyt/Eoly, Hydrogenics, Fluxys and Elia, as well as Zeebrugge harbor, Gent university and the hydrogen club Waterstofnet are joining forces in the Greenports study. Goal is to create a blueprint for large-scale hydrogen production in an harbor environment, read: convert offshore wind electricity in hydrogen. Focal point is the harbor of Zeebrugge.

For obvious reasons, the Belgians have been pushing hardest for a revitalization of the IJzeren Rijn (Iron Rhine) railway between the Antwerp Harbor and German Ruhr-area industrial heartland. The Germans had a prudent approach, but the Dutch were least enthusiastic in cooperating with a project that would create an outright competitor with their own existing railway-lines between Rotterdam and Germany. Now the Germans are changing attitude and offer to take the lead in revitalizing the old railway-line. And there is a reason why even the Netherlands should reconsider its position. And that reason is the zinc-plant in Budel-Schoot and its potential to become a renewable energy fuel source, see previous post.

A new proposal for revitalization of the Iron Rhine can be best accomplished using the 3RX-tracé, the ‘Rhein-Ruhr-Rail Connection’ (3RX), from Antwerp, via Mol and Hamont to Roermond and Venlo and finally to Viersen. It would be just as good as revitalizing the historic Iron Rhine, but at half the cost.

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.
The Flamish energy thinker Kris De Decker blogs at “Low Tech Magazine“, was guest author at “The Oil Drum” and writes for many prominent newspapers in Belgium, the Netherlands and the UK. De Decker presents a big picture view on the possibility of a 100% renewable energy society. De Decker preaches “low tech” if not “no tech”.
[lowtechmagazine.com] – How (Not) to Run a Modern Society on Solar and Wind Power Alone
The author admits that there is potentially more than enough renewable energy available. In Europe 10 times, in the US even 100 times present day electricity consumption, that’s not the problem. The real issue is intermittency. How can we guarantee that our energy grids remain stable, like they have been over the past hundred year, when we switch from fossil fuel to renewable energy? They author describes the intermittency of wind and solar in more detail and we assume he has done his homework. A first positive observation is that throughout the year solar and wind intermittency somewhat compensate each other. There is more wind in the winter months and more solar in the summer.
De Decker lists five strategies to combat the negative consequences of intermittency:
There is not much wrong with the article and De Decker basically supports the idea of a 100% renewable society even if he is skeptical that we can have a plug-and-play solution and instead advocates that we should learn to live with a less comfortable situation where demand will follow supply instead of the other way around.
Is he right? Eh no. He is ignoring the impact of other promising storage technologies. Take the blueprint of the 100%-renewable energy model as promoted by the renowned German Fraunhofer Institute. Note this is the overall energy picture, not just electricity. The model and numbers are for Germany, but can be scaled up for Europe, with adaptions in the numbers for the respective local situations:
[source] 100% renewable energy blueprint for Germany according to the Fraunhofer Institute
Summary in numbers:
Input: 542 GW intermittent renewable energy, mostly wind (200 GW) and solar (252 GW).
Storage: batteries 52 GWh, pumped hydro 60 GWh, power-to-gas (methane) 88 GW and other, see legenda:
Gud – “Gas und Dampf” (gas and steam).
KWK – “Kraftwärmekopplung” (co-generation. “power-heat-coupling”)
Solarthermie – thermal solar (solar collectors)
BHKW – “Blockheizkraftwerke” (co-generation. “block heat and power generation”)
Gas-Wärmepumpen – Gas-heatpumps
Pumpspeicher – Pumped storage (hydro)
Wärmespeicher – heat storage (water medium)
Wärmelast – heat load
WP – “Wärmepump” (heat pump)
Überschuss Wärme – Excess heat
Essential is the Energiesanierung (energy renovation) of buildings, which should result in a reduction of space heating energy requirement of 64.9% as compared to 2010 level.
According to the Fraunhofer Institute would the cost of this renewable energy system not be higher than our current fossil fuel based energy system.

[source] The Belgians conveniently located one of their two nuclear power stations in Doel at the border with the Netherlands. If something goes wrong, large parts of the Netherlands will become uninhabitable, but not Belgium.
The German government is preparing “critical questions” to the Belgian authorities on operational safety at the nation’s two active nuclear power plants, following a number of recent successive incidents at nuclear facilities.
After incidents at both Belgian nuclear power plants, German Environment Minister Barbara Hendricks has again put her concerns point-blank, demanding whether security is guaranteed at the Belgian NPPs, proposing Brussels to get rid of the nuclear energy altogether. The minister said, though, that the final decision remains with the Belgian people…
“As long as these reactors that are falling to bits remain online nuclear incidents cannot be ruled out,” North Rhine-Westphalia’s regional minister Johannes Remmel was quoted as saying by the Belgium news outlet Flanders News on Tuesday. After “all these incidents,” it is strange that Belgium’s nuclear authorities are not considering taking all the country’s nuclear reactors offline, Remmel also said.
This should be the Dutch government saying this, before the Germans.
Reaction of the Dutch government: next year we’ll take in 250,000 refugees.
Chernobyl Exclusion Zone (red) projected over Israel, north of their nuclear facility Dimona. That’s more than 150 km. If Doel goes down, cities like The Hague, Rotterdam, Amsterdam, Utrecht would become uninhabitable. And since Rotterdam is the gateway to Europe, the consequences would exceed a much larger area than the Netherlands alone. That maybe the reason why the Germans sound the alarm bell.
And since with prevailing winds in the Netherlands from the South-West, this is news directly involving yours faithfully.

The idea is not new: build a circular dike in the sea and pump water out of it with energy from wind turbines for storage purposes if there is no actual demand for energy, like during the night. Let water flow back in again, propelling turbines to generate energy on the moment that you need it.
In 1981 the Dutch engineer Lievense presented the plan for this type of storage, but that was 1981 (when we heard him present his plans at our university) and now is 2015, where the energy problem has become acute. Decision for a go ahead: this summer.
Discharge capacity: 500 MW for four hours
Max. difference water levels: 30 meter

The Enercon E-126, the largest windturbine in the world until Feb 2012. Hub height 135 m, rotor diameter 127 m, 7.5 MW, yearly yield 18 KWh. Eleven of those engines are installed in Estinnes/Belgium. Expected production of these eleven machines combined: 195 GWh or 17.7 GWh per tower per year. List price: eleven milion euro. Assuming a yearly maintenance cost of 2%, this would increase total cost to 17.6 million euro. Expected operational life: much longer than 20 years. Assuming 30 years, this would mean a power production of 531 GWh. Assuming market price for electricity from the grid of 20 euro cent/kwh, this would equate to an amount of power worth 106 million euro or six times the total cost of the machine, a spectacular return on investment. The turbine does not use rare earth magnets.
