World’s Largest Wind Tower Arrives in Rotterdam

GE-Owned, French-built Haliade-X 12 MW tower arrives in Rotterdam Harbor. The wind turbine will be operational later this year and set a new 12 MW standard for offshore wind in 2 years time and play a central role in the ambitious Dutch plans to roll out 17.5 GW’s worth of wind power (for starters in the twenties):

Liquid Air Energy Storage (LAES)

British research club reports the results of their analysis of a liquid air storage system (LAES). The idea is to use renewable electricity to liquefy air for energy storage purposes. Result: storage cost 11 euro cent/kWh for a 20MW/800 MWh storage installation at a round-trip efficiency of ca. 50%. Storage pressure ambient. Recuperation by boiling the liquid and drive a turbine in a Rankine cycle. Efficiency could be increased by combining solar of waste heat, thus increasing the temperature at the expansion phase. Storage of liquid air in large volumes is fairly easy with an energy density of 83 kWh/m3.

To really solve the renewable energy storage problem, as a rule-of-thumb, a country needs to be able to store ca. 41% of its annual energy consumption, in order to reasonably guarantee energy supply security. Let’s apply this to a country like the Netherlands, with an average power need of 13 GW. Given the energy density of 83 kWh/m3, a storage volume of 562 km3 would be required, which is unrealistic. Liguid air storage is a short term storage possibility (think in a range of hours, not months).

The real solution of the long term storage problem doesn’t lie in gravity batteries or even phase change solutions, like the one presented her, but in combustible material, reduced with renewable means: hydrogen, iron powder, borohydride, ammonia, methanol, formic acid and a wide range of other possibilities.

German Renewable Energy Transition in Trouble


Der Spiegel sounds the alarm bells: the German Energiewende is stalling. Few new wind turbines are currently being installed, only 35 in H1-2019, the lowest rate since 2000! This year new installations to the tune of 1.5 GW can be expected at best, down from 5.3 GW in record year 2017. The minister of economic affairs and transition proponent Altmaier is forced to call for an emergency meeting with all parties involved. 26,000 jobs were lost in the wind branche since 2017. Several companies went bust.

Who are the main culprits?

1. German government (Altmaier’s ministry)
2. German public (“not in my backyard” attitude)

Ad 1) Since 2017, the German government introduced a new dubious tender system for new wind parks. Additionally: bureaucracy. A lot of wind projects are in the pipeline, waiting for approval… and stay there (10 GW or more). Furthermore, regulations are too restrictive, killing off projects for no good reason, like excessive distance from urban areas, radio masts, etc. Currently renewable electricity in Germany is at 40% and should be 65% in 2030. That’s going to be difficult to achieve, according to der Spiegel.

Hopefully the upcoming emergency meeting after the Summer will address the issues raised above.

[] – Economics of converting renewable power to hydrogen

The recent sharp decline in the cost of renewable energy suggests that the production of hydrogen from renewable power through a power-to-gas process might become more economical. Here we examine this alternative from the perspective of an investor who considers a hybrid energy system that combines renewable power with an efficiently sized power-to-gas facility. The available capacity can be optimized in real time to take advantage of fluctuations in electricity prices and intermittent renewable power generation. We apply our model to the current environment in both Germany and Texas and find that renewable hydrogen is already cost competitive in niche applications (€3.23 kg⁻¹), although not yet for industrial-scale supply. This conclusion, however, is projected to change within a decade (€2.50 kg⁻¹) provided recent market trends continue in the coming years.

Dutch Climate Accord Presented

The Dutch government has presented ambitious plans to completely reorganize the energy landscape in the Netherlands. The plan needs to be realized in 2050 and 2030 is an important intermediate milestone. The bullet points:

  • By 2050 CO2-emissions reduced to 5% of 1990 level. In 2030 a reduction of 49% compared with 1990.
  • District heating in larger cities.
  • “heat fund”, providing cheap long-term loans to the public for energy transition purposes.
  • The Netherlands is divided in 30 energy regions, that each should provide plans (RES, “regional energy strategy”) how to achieve full decarbonization (thermal isolation, heat pumps, etc.).
  • Electricity to become cheaper, natural gas substantially more expensive. Heating and cooking on gas needs to be phased out.
  • Rapid closure of the 5 remaining coal power stations in the coming few years.
  • As of 2030, all new cars need to be e-vehicles. Two-wheelers must be electric as of 2025.
  • In the coming few years new e-vehicles are to be subsidized with 3000,- euro to stimulate demand.
  • Road pricing almost certainly to happen (paying per kilometer, probably as of 2026)
  • The size of the national livestock is to be diminished.
  • Industry CO2 tax in 2021. 30 euro per ton, gradually increasing to 150 euro in 2030.

Hydraulic Air Compressor Demonstrator Project

Hydraulic air compression site in Sudbury, Canada

Modern man is used to power distribution via electricity. There is an alternative though, that was once used in fairly sophisticated places like Paris: pneumatic power distribution. Pneumatic power distribution comes with efficient storage possibilities of excess renewable electricity (CAES). It’s even possible to contemplate skipping intermediate electric conversion altogether and use your wind turbine as a compressor.

A research project in Sudbury, Ontario, Canada, wants to (re)introduce pneumatic technology in a mining environment. The pressure is generated via falling water from high altitude (the hydraulic part), in a near-isothermal, energy efficient process.

Hystock Hydrogen Factory Opened in the Netherlands

Potential hydrogen demand industrial clusters 2030

Today, the Dutch king Willem-Alexander opened a pilot hydrogen production facility named Hystock in Veendam, in the North of the Netherlands. The facility has a power-2-gas capacity of 1 MW, sufficient to permanently keep 80 cars going.

The so-called “hydrogen coalition” lobby organisation, that has a members all the big names like Tennet, Nuon, Gas-Unie, Tata Steel, Port of Rotterdam, TU-Eindhoven, Greenpeace and many others, pleads for 3-4 GW capacity by 2030. The Netherlands on average consumes 13 GW electricity. The country has a vast natural gas network that can be retrofitted for hydrogen. A price level of 1.5-3 euro per kg hydrogen is considered to be feasible for 2030. Required annual investment is 300 million euro until 2030.

VPRO Tegenlicht – Waterstof de Duurzame Oplossing

De Energietransitie: Is Waterstof Het Nieuwe Gas?

Met het initiatief van Haven Amsterdam, Tata Steel en Nouryon om een waterstofproductiefabriek in het Noordzeekanaalgebied te willen gaan bouwen, wordt de Metropoolregio Amsterdam het centrum van de productie in duurzame energie, opgewekt door windmolens op zee. Het lijkt alsof waterstof de heilige graal is naar een duurzaam alternatief voor fossiele brandstoffen. Maar wat is waterstof precies? En wat kunnen we er mee? En wie gaan dit gebruiken?

VPRO Tegenlicht – Deltaplan Waterstof

Wat betekent waterstof voor de energietransitie?

Een nieuw element dient zich aan als versneller van de energietransitie: waterstof. Het lichtste gas dat we kennen heeft alle potentieel om dé centrale plek van duurzame energiedrager in de economie van morgen in te nemen. Het kan namelijk de overtollige energie van zonnepanelen en windturbines opslaan, om zo te voorzien in een continue energiestroom voor industrie en huishoudens. Kunnen we, als Nederland straks van het aardgas af gaat, het bestaande gasnet gebruiken voor groene waterstof? Waterstofproductie biedt nieuwe kansen voor Groningen en de eerste auto’s aangevoerd door waterstof rijden al rond. Wat moet er daadwerkelijk gebeuren om het potentieel van waterstof waar te maken? Is waterstof nu werkelijk de absolute weg voorwaarts of is er nood aan nuance? Wat is het potentieel van waterstof voor de energietransitie?
