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.

30 energy regions that all need to come up with a detailed plan for the local situation.

Air Compression Example Projects

As of 2017, only 2 CAES installations are operational world-wide, one in Germany, one in the US.

Huntorf, Germany. Operational since 1978, output 290 MW daily or 321 MW max for 2 hours, thanks to storage, consisting of 2 135,000 m3 large underground cavities, at a depth of 650-800 meter, with air pressures of up to 50-70 bar. Efficiency at 42% if compression heat is not used (adiabatic compression). For the future, efficiencies of up to 70% are to be expected.

McIntosh power plant in Alabama, operational since 1990. Output from CAES storage 110 MW over 26 hours, with heat recuperation, leading to an efficiency of 54%. The 2015 video confirms that until 2015 there were only two CAES plants in the world and only one in the US (the other Huntorf in Germany)

Currently underway is a project in Northern Ireland, funded by the EU and hopefully survives the Brexit drama; 330 MW from storage for 6 hours:

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?

Rumours About an Airbus Hybrid Plane A320neo Successor

Airbus is under strong pressure from European governments to reduce CO2 emissions. Bloomberg reports that Airbus is contemplating designing a hybrid electric-gasoline A320neo successor.

World’s First Solar Car Presented in the Netherlands

Lightyear One is a Dutch startup, emerging from the Technical University Eindhoven-based Solar Team Eindhoven, that very successfully participated in several editions of the Australian World Solar Challenge, see links below. The company presented today their first “solar car”, a car that in sunny climates can drive for months without having to be recharged, provided it is parked in the sun and not under trees or under carports. With this condition fulfilled the car can drive ca. 20,000 km in sunny climates, like in most parts of the US or southern Europe, 10,000 km in cloudy Holland, without external charging. Note that in Holland average annual distance driven is ca. 13,000 km.

Data sheet:

– 5 m2 solar cells
– Max range with charged batteries and additional sun: 725 km
– No rear window, camera’s only
– CW-value: less than 0.20
– 4 electric motors in the wheels
– Weight ca. 1000 kg
– 2021 small scale production
– End 2022 1500/year production
– 2024-2025 mass production in Helmond
– Design Lowie Vermeersch (Ferrari e.o., #12 in world car designers ranking)
– Initial price low volume production: 119,000 euro
