Self-Climbing Crane Making Progress

The idea is to substantially cut cost installing a wind turbine by using the turbine itself as a crane. The first (positive) experiences are now in with the construction of a 4.5 MW turbine. Large cranes are no longer necessary anymore.

Battolyser – 90% Storage Efficiency With Combining Batteries and Electrolysis

[source]

The idea: combining battery and hydrogen-production functionality in one device. Battery + electrolysis: battolyser. Players: Technical University Delft and Proton Ventures from Schiedam, Netherlands. The battery is Thomas Edison patented technology from 1901. The production of hydrogen was so far an unwanted side effect during charging of the battery. Researchers now want to turn this bug into a feature. The production of hydrogen begins when the battery is as good as fully charged. It is this combination that leads to an excellent overall storage efficiency of 90%. All you need is abundant available zinc, iron and water.

First experiments early 2019 with a 15 kWh prototype, but the university, energy giant Nuon and Proton are already thinking aloud about a 10 MW model

Our results demonstrate a remarkable constant and a high overall energy efficiency (80–90%), enhanced electrode storage density, fast current switching capabilities, and a general stable performance. The battolyser may enable efficient and robust short-term electricity storage and long-term electricity storage through production of hydrogen as a fuel and feedstock within a single, scalable, abundant element based device.

Developments in Growing Food in an Age of Climate Change

Scientists in the Netherlands say they are close to a breakthrough which will allow crops to be grown in deserts. Many say this could completely alter life on the African continent and even end hunger. World leaders meeting at the climate talks in Germany are being urged to commit to more funding for new agricultural projects in drought-stricken parts of the world.

  • productivity: 900 head of lettuce per m2 (200 kg). Any other crop will do as well.
  • 1 hectare (100m x 100m): 4 workers, mainly supervising. Planting, watering, harvesting, packaging, all automated
  • production: around the year, completely planned, meaning little necessity for storage. Straight from the “field” to the super market
  • these production facilities can be build next to Amsterdam, Stoke-on-Trent, Johannesburg, Riaydh, Reykjavik, anywhere. Almost complete independence from environmental conditions
  • almost no transportation cost: production next to consumers
  • lights from leds doesn’t take that much energy. And if you don’t stack, you can let in sunlight (Summer)
  • Water requirements: near zero. All water remains in the building, apart from the small quantities embedded in the product

The Netherlands is Placing its Bets on the Hydrogen Economy

Natural gas power plant Eemshaven. One of the blocks is retrofitted for hydrogen.

The Netherlands are “plat als een dubbeltje” (flat as a dime) and as such pumped hydro storage solutions are virtually impossible. The people behind the recent Climate Accord, that is from the industry to environmentalist groups, see hydrogen as the key of the energy transition. Current annual hydrogen production (from natural gas) is 800,000 ton, mostly for agriculture and refineries. The goal is “green hydrogen”, produced from solar and wind, without CO2 as a byproduct. Hydrogen is needed for several purposes: as storage and for certain aspects of industrial society that can’t be covered with electricity alone. Batteries alone are no solution. For the storage of 2000 kWh you would need 3 sea containers per household at the cost of 40,000 euro/year. You can store the same 2000 kWh worth of energy in a hydrogen container of merely 1 m3. And yes, there are considerable conversion losses from electricity –> H2 –> electricity, but hydrogen can be exported via existing but retrofitted natural gas networks, where building new cables would be 100-200 times more expensive.

Dutch industry is already busy with laying the foundations of a hydrogen economy. In the northern Groningen province, GasUnie is developing a small factory where solar electricity is converted in hydrogen (“power-to-gas”). The best location for large scale hydrogen factories is probably at sea, near the wind parks. Fortunately there is an enormous pipeline infrastructure in the North Sea, a left over of the gas and oil age, that can be reused for hydrogen. Large scale hydrogen production won’t happen before 2030, simply because there is yet not enough wind power generated that can’t be used immediately. 3,000 turbines are seen as a critical number from where storage would become necessary.

Currently Holland is competing with post-Fukushima Japan to be the owner of the first hydrogen economy.

Nederlandse Regering Presenteert Klimaatakkoord

Today the Dutch government presented its “klimaatakkoord”, a detailed energy strategy for the coming three decades. Core points:

– 49% less CO2 emissions in 2030 as compared to 1990, more than the 40% required by EU regulation
– Lower taxes on electricity and higher taxes on natural gas to encourage the transition
– 11.5 GW North-Sea wind by 2030
– 75 GW North-Sea wind by 2050
– Required extra investment: 15-20 billion euro
– CO2 sequestration is an option
– 3-4 GW hydrogen production by 2030
– By 2030 84 billion kWh needs to be renewable, 5 times the 2018 amount. 49 billion Kwh will be from offshore wind
– 50% of the renewable energy capacity needs to be owned by local parties, like private households
– Demand management will be introduced
– Intermittent supply is admittedly “a problem”, c.q. “challenge”
– Traffic becomes “green”
– Most of the Dutch part of the North-Sea will be filled with turbines; fishing will be impossible for large ships.

The Dutch government exploited its huge natural gas reserves to the max in order to avoid being stuck with stranded assets, but now that due to soil subsidence further large scale extraction is no longer possible, the government is radically changing course and has the ambition to advance from being Europe’s rear light in all things renewable energy into becoming a front-bencher. The government can build on deep acceptance within Dutch society for the expensive transition that lies ahead.

[nu.nl] – Dit betekent het klimaatakkoord voor je woning

In de komende drie jaar worden 102.500 bestaande corporatiewoningen van het gas afgesloten… Energie moeten we dus uit andere bronnen gaan halen. Nieuwbouwwoningen worden sinds 1 juli niet meer aangesloten op het gasnetwerk… Dat betekent niet dat je als huiseigenaar zelf verantwoordelijk bent voor het verzinnen van de beste aanpak. In het akkoord staat dat gemeenten in Nederland eind 2021 hun visie op deze transitie moeten vaststellen. Daar moet in staan welke wijken wanneer worden aangepast. Woningen worden wijk voor wijk verduurzaamd. Dat kan met warmtenetten, helemaal elektrisch, met warmtepompen of met duurzaam gas. Gemeenten moeten samen met bewoners en gebouweigenaren per wijk de beste oplossingen bepalen. Het isoleren van je woning wordt in 2030 verplicht. Je gemeente vertelt je vanzelf welke maatregelen er in jouw wijk worden genomen… In het akkoord wordt een nieuw soort lening omschreven: de gebouwgebonden financiering. Daarmee wordt het voor huizenbezitters eenvoudiger om ook maatregelen te nemen. De lening is gekoppeld aan het huis en niet aan de eigenaar. De kosten van de lening mogen niet hoger uitvallen dan wat de verlaging van de energierekening oplevert. De looptijd van een lening wordt dertig jaar en gaat dus over van bewoner op bewoner. Ook krijgen huizenkopers bij elke aankoop een aanbod om woningen te isoleren met financieringsmogelijkheden… De subsidie op zonnepanelen is al stopgezet, maar de overheid geeft nog steeds subsidie op de aanschaf van zonneboilers, warmtepompen, pelletkachels en biomassaketels.

[energiegids.nl] – Voorstel Klimaatakkoord gepresenteerd

[eufin.nl] – De verbouwing van Nederland beginnen

Al ruim voor 2030 verduurzamen we ieder jaar 200.000 woningen. Daarmee reduceren we onze CO2-uitstoot enorm. Een CO2-neutrale gebouwde omgeving in 2050 is geen utopie, het kan echt… De komende jaren zetten we bovendien alles op alles om meer technici op te leiden voor de energietransitie… Het Klimaatakkoord schrijft het huidige aardgasnetwerk nog niet af. Daarmee blijft de mogelijkheid open in de toekomst gebruik te maken van duurzaam gas. Het huidige gasnetwerk is daarvoor uitermate geschikt. In het akkoord is op aandringen van UNETO-VNI opgenomen dat er demonstratieprojecten komen voor duurzaam gas en waterstof. De installateurskoepel verwacht dat dit een belangrijke bijdrage gaat leveren aan de energietransitie. Woningen zullen worden verwarmd door warmtenetten en collectieve of individuele (hybride) warmtepompen.

[engineersonline.nl] – Industrie gaat CO2 ondergronds opslaan

De industrie moet inzetten op efficiëntere processen en efficiënt gebruik van warmte. Schone stroom vervangt op termijn fossiele brandstof en grondstoffen worden hergebruikt of vervangen door duurzame grondstoffen. Omdat deze omschakeling tijd en geld kost, wordt eerst gestart met de ondergrondse opslag van CO2… Ondergrondse opslag van CO2 is nodig om in 2030 genoeg CO2 uit de lucht te houden… Arbeidsmarkt en scholing zijn sterk bepalend voor het tempo van de energietransitie en het draagvlak daarvoor. Om de klimaatdoelstellingen mogelijk te maken zijn tienduizenden extra vakkrachten nodig, die nu al niet gemakkelijk te vinden zijn. “Het is nu aan het kabinet en de Tweede Kamer om met richtinggevende keuzes te komen”, zegt voorzitter van het Klimaatberaad Ed Nijpels. “Daarna kunnen de partijen de hoofdlijnen uitwerken in concrete en bindende afspraken. Als het tempo erin blijft, ligt er eind dit jaar een akkoord met handtekeningen… Het is de bedoeling dat de zeven miljoen huizen en miljoen gebouwen in Nederland met duurzame warmte worden verwarmd. Hiervoor wordt een wijkgerichte benadering gehanteerd. Om het aanbod van duurzame warmte te vergroten, wordt geothermie fors opgeschaald. De ambitie is een uitbreiding van 3 petajoule naar 50 PJ in 2030 en meer dan 200 PJ in 2050.

Waterbeheerders willen werk maken van aquathermie, het gebruik van koude en warmte uit afval- en oppervlaktewater. Zij verwachten 80 tot 120 PJ in 2050 te kunnen realiseren. Deze energiebron is relatief nieuw, waardoor nog veel ervaring nodig is. Daarom wordt voorgesteld om vanaf 2019 een driejarig programma voor aquathermie uit te voeren. Tevens wordt aquathermie onderdeel van een aantal proeftuinen in het kader van het 100-wijken programma, dat is bedoeld om jaarlijks 30.000 tot 50.000 bestaande woningen aardgasvrij te maken voor het eind van de kabinetsperiode…

Waterstof wordt aangeduid als een sectoroverstijgende hoofdlijn. De sectortafels voor elektriciteit en industrie stellen een programmatische aanpak voor. Hierin worden de investeringskosten van elektrolyse versneld verminderd, zodat groene waterstof die is opgewekt uit duurzame bronnen (wind en zon) een goede rol in de toekomst kan spelen. De ambitie is om 3 à 4 gigawatt aan groene waterstof in 2030 te produceren.”

[h2owaternetwerk.nl] – Stevige Bijdrage van Aquathermie en Groene Waterstof

Het Voorstel voor hoofdlijnen van het Klimaatakkoord zoals het document officieel heet, is opgesteld door meer dan honderd maatschappelijke partijen. Zij hebben vier maanden lang gediscussieerd aan vijf sectortafels: elektriciteit, gebouwde omgeving, industrie, landbouw & landgebruik en mobiliteit. De organisaties dragen de bouwstenen aan voor hoe Nederland de doelen in het Klimaatakkoord van Parijs kan halen.

Chairman Dutch building industry Maxime Verhagen expresses his support for the Klimaatakkoord


Major Dutch banks have announced to support the transition by providing long-term loans (think 30 years or even intergenerational) to make houses more sustainable (isolation, heat pumps, solar panels). After 2030 taking up loans for this purpose could become obligatory.

Groningen Wants to Become the Dutch Hydrogen Province

Why Groningen? Prof. van Wijk and premier hydrogen evangelist in the Netherlands sums it up:

1. Paris Accords. Not specific for Groningen, but important stimulus.
2. Groningen produced natural gas for decades. The expertise and infrastructure for a replacement is there.
3. There is a lot of renewable electricity on offer from Norway and from Danish, German and Dutch offshore wind parks.
4. There is a lot of chemical industry already present that could work with hydrogen.

The goal is to produce 270,000 tons of hydrogen annually, in order to bring down per kilo hydrogen prices to 2-3 euro.

Two-Blade Wind Turbines Are Back, This Time Offshore

Why three blades if two blades work as well? It is all the fault of 1970s Danish garage pioneers, who insisted there needed to be three blades. NASA did experiment at the same time with 2-blades (WTS-4), but that project was cancelled under Reagan, who decided that oil was American, not wind. And now we are stuck with three blades.

Or are we? The originally Dutch company Sea Wind Technology is betting on two-blades, especially for offshore, with higher wind speeds (higher loads) and more difficult installation.

Advantages two blades:

– simpler design
– less material (50% less weight, no heavy tower/monopiles necessary)
– easier offshore transportation and mounting (just pile them up)
– simpler installation vessels, flat barges suffice
– more rotor flexibility, 2 degrees of freedom: rotating and teetering, reducing load
– 2% less electricity gain, but offset by much lower installation and operational cost
– Levelized cost (LCOE) reduction: 50%
