Car as Power Plant: nieuwe mijlpaal bereikt!

CaPP_socket_plugEuropese primeur voor Delftse onderzoekers: brandstofcelauto die stroom levert

Onderzoekers van de TU Delft zijn erin geslaagd om een stopcontact als elektriciteitsuitgang te ontwerpen en te installeren op een brandstofcelauto. In samenwerking met innovatieve marktpartijen als Accenda, Stedin, Hyundai, RDW en GasTerra en studenten van de TU Delft, de Haagse Hogeschool en het ROC Mondriaan hebben ze gezorgd dat de zero-emission Hyundai IX35 FCEV nu een energiecentrale op wielen is; een Europese primeur.

Car as Power Plant
De onderzoeksgroep Future Energy Systems van professor Ad van Wijk binnen de vakgroep Process & Energy, faculteit 3mE, doet onderzoek naar verschillende geïntegreerde systeemtoepassingen van brandstofcellen, zoals in het programma Car as Power plant. Brandstofcelauto’s produceren elektriciteit, warmte en schoon water uit waterstof. Dat kan worden gebruikt in huizen, scholen en kantoren. De omgebouwde Hyundai brandstofcelauto kan nu 10 kW vermogen leveren. Dat is genoeg om gemiddeld tien huizen te voorzien in hun elektriciteitsgebruik. Met het stopcontact zijn de innovatoren in staat om de auto elektriciteit geprogrammeerd te laten leveren aan het elektriciteitsnet of direct aan een woning, bijvoorbeeld als aanvulling op zonne- en windenergie. Deze toepassingen worden in de volgende fase onderzocht en getest.

Omdenken in het systeem
Deze innovatie brengt meerdere technologische innovatievraagstukken met zich mee: hoe kan deze auto zijn elektriciteit zodanig leveren dat het elektriciteitsnet met een wisselend aanbod aan zonne- en windenergie stabiel wordt. En hoe kan lokaal en op een duurzame manier de benodigde waterstof worden geproduceerd uit bijvoorbeeld zonne-energie, worden opgeslagen en worden gedistribueerd? Ook ontstaan er vragen op andere, niet technologische domeinen, bijvoorbeeld als het gaat om het verdienmodel van energiebedrijven, de acceptatie door automobilisten, de bestaande wet- en regelgeving omtrent energieproductie en distributie of de training en opleiding van de installatiebranche en automobielindustrie. Om dit soort innovaties uiteindelijk in de praktijk te laten slagen, is het belangrijk te innoveren en om te denken op systeemniveau.

Systeeminnovaties op The Green Village, TU Delft.
Op de campus van de TU Delft werken vele marktpartijen samen aan innovaties op systeemniveau. The Green Village, het ‘levende systeemlab’ van en voor de TU Delft, dat momenteel in ontwikkeling is, brengt alle benodigde stakeholders bij elkaar. Wetenschappers en studenten, bedrijfsleven en overheden participeren in verschillende innovatieprogramma’s, waaronder Car as Power Plant. Al deze partijen werken gelijktijdig, ieder vanuit zijn eigen discipline en expertise, samen aan duurzame innovaties. Zo versnellen we de ontwikkeling ervan en werken we gezamenlijk aan een duurzame toekomst.

“The energy sector has nothing to do with energy companies anymore”

-This interview was originally posted on Energy Post
Recap in Dutch at newspaper Trouw

There are many developments in the world today that have far more influence on the energy sector than the energy sector itself, says technology visionary Ad van Wijk in this exclusive interview with Energy Post. The Professor in “Future Energy Systems” at Delft University of Technology in the Netherlands explains how LED lighting, a DC grid, fuel cell cars, the Internet of Things and 3D printing are upending our energy system as we know it. “The potential electricity production capacity of our cars – if they became fuel cell cars – is ten times that of our power plants worldwide.”

“The energy sector will develop outside of energy companies,” predicts Ad van Wijk, Professor for Future Energy Systems at Delft University of Technology in the Netherlands. Academic, sustainable energy entrepreneur and innovator, one of Europe’s most influential thinkers describes the paradigm shifts he sees: a switch to LED lighting, a DC grid, and fuel cell cars, plus the emergence of the Internet of Things and 3D printing.

advanwijkOriginally a physicist, with a PhD in wind energy and electricity production, Van Wijk went on to found consultancy Ecofys in 1984. It later became part of Econcern, a company founded by Van Wijk, which he wanted to turn into “the Shell of renewable energy”. In its heyday it owned a wide range of activities and assets, including an offshore wind  farm, several multi-MW solar farms, a bio-methanol plant, energy-producing greenhouses, and a production company making electric vehicles. It also launched a tool to visualise energy consumption in buildings. Thanks to Econcern, Van Wijk was elected Entrepreneur of the Year in the Netherlands in 2007 and Top Executive of the year in 2008. The company turned out to be too ambitious, however, and went bankrupt the next year when the economic crisis hit. Ecofys and several other parts of the business were bought by Dutch utility Eneco.

Today, Van Wijk remains involved in initiatives such as the “Green Village”, a testing ground for new technologies at Delft University of Technology. In this interview, he explains why the positioning of LED lights is as important for energy efficiency as the LED-technology itself. He argues that without changing from an AC to a DC grid, we will never be able to have an energy system based on renewables. He wants us to replace our power plants with cars. And he enthuses about how the Internet of Things and robots with batteries will make demand more flexible than ever before. Van Wijk believes these changes will start to transform the energy system in the next 5-10 years. The biggest problem? Energy companies don’t see it.

Q: What is your vision for the future of our energy system?

A: I am interested in the effect of new technologies on our energy system. Today, I am working on three main paradigm-changing concepts in the energy sector.

The first one is what we call the LED revolution. We are already changing light bulbs to LED light bulbs. Yet a lot of the energy that is wasted in a lighting system is not because a light bulb is inefficient but because you are producing light at the ceiling and consuming it near your eyes. The distance between the production and consumption of light has a lot of energy losses.

Now the interesting thing is that LED is very small – you could integrate it near to your eyes, in a table, chair or even in your clothes or glasses. Then you can save energy from a better technology and a reduced distance for the light to travel. We are only starting to do this.

A lot of the energy that is wasted in a lighting system is not because a light bulb is inefficient but because you are producing light at the ceiling and consuming it near your eyes

Q: What is the size of the efficiency improvement from LED lighting?

A: LED as a technology is 4-5 times more efficient than a regular light bulb and we guess you can have the same improvement again with the distance reduction.

The next step is that LED is a diode – it is also in your TV screen for example – so you can develop new functions for the LEDs integrated into your tables, the floor etc. A company like Desso, which makes carpets, and Philips, which makes LED lighting, have partnered up to integrate LEDs into carpets that can guide you through a building, for example. If you arrive at an office looking for a Mr Petersen, your phone and the LEDs could guide you there. This can also be done in streets or parking lots. So it is a route to new, more integrated products that make your environment smarter.

Q: Apart from LED, what are the other two paradigm shifts you see coming?

A: Second, is the grid. Today the electricity grid is AC (alternating current). But all of our appliances – fridges, LED lighting etc – work on DC (direct current). And all renewable energy production is DC.

So our system today is that if we have a solar cell, we have to convert the electricity [it produces] from DC to AC, put it in the grid at home, and then convert it back from AC to DC in every appliance. If you want to use your car battery to store electricity, you have to convert the power from AC to DC to store it and back again to release it into your house. Every conversion step is a loss in energy. So, we need to change the entire electricity grid into DC.

Today the high-voltage grid across seas and oceans is already DC, it’s called HVDC. We want to do the same at the medium- and low-voltage level. The interesting thing is that you can easily have the 350-400V DC grid in your house – you don’t have to change your wires and you don’t have to change your appliances.

The only thing you have to do is that at this moment all your appliances have an AC-DC converter, but in future you can leave that out. The same is true for a solar system – today you need a DC-AC converter but with a DC grid, you can leave it out. This means you can save 5-10% on investments in a solar system. So it’s not only that you save on energy, you also save on cost.

If you want to develop a totally renewable energy system, you need to do that on DC, in my view it is simply not possible with an AC grid

Q: Why is the grid all AC so far?

A: It’s because of a past battle between Mr Edison and Mr Tesla. Edison, who invented the light bulb, was already working on DC at the time. Tesla was connected to Westinghouse and they made large power plants (initially hydro). The electricity produced somewhere in the Great Lakes had to be transported to Washington DC over a large distance. At the time, Tesla could increase the voltage to a higher level on AC and reduce the loss through cables over a large distance.

So he won that battle you could say. At the time we didn’t have the chips and motors working on DC like today.  Today, because of the introduction of chips, every appliance works on DC. Today, power electronics have developed and we can transport long distance over DC also. All the equipment for a DC grid is there. The only thing we have to do is change the system, which is of course a big change, a paradigm shift.

But you can do it gradually, in parts, even at house level. You could install an AC-DC converter at your doorstep for example. Then you distribute on DC in your house. You save on energy but also on the inverters that you otherwise need.

An example of an energy system of the future

“We do a test in a greenhouse in the Netherlands where we grow tomatoes. Normally you have a lighting system on the ceiling to help the plants grow faster. What we’re doing now is changing to LED lighting. And we want to put the LED lights in between the plants. But it turns out that we cannot do that because every string of LED lights has an AC-DC converter at the end, which has energy losses, which means it becomes hot. If you put this converter in between the plants, they are burned. So what we do is we put the converter outside the greenhouse and a DC grid inside, so that we don’t produce that heat anymore, can put LEDs in between the plants and reduce the energy use by a factor of 10. But we also save 1000 kg of copper per hectare because every AC-DC converter has copper wiring. And now we need only one, not one for every string of LED lights. So this is not only saving on energy, but also on materials.

In the end, if you want to develop a totally renewable energy system, you need to do that on DC because you need so much copper if you have to convert DC to AC and AC to DC again, in my view it is simply not possible with an AC grid. You need to change the system. It’s nothing to do with production, but everything to do with the distribution and use of your electricity.

Q: Who is the driving force for this makeover?

A: For HVDC it’s really the industry – companies like Siemens, GE etc. At the low-voltage level, you see that it is especially smaller, specialised companies. For example there is a company called Nextek in the US that is delivering this kind of systems for your home.

Every fuel cell engine can provide the electricity for 100 houses, not just one. So we can replace our power plants by cars

Energy companies are, sometimes reluctantly, studying the subject. Public authorities are getting more and more interested. But when you look at the electricity laws or codes for the public grid or grids in buildings, you’re not allowed to do something on DC. This is true at EU and also national level. Nobody ever thought you could do it on DC. Therefore the regulations and codes are written in such a way that you can do it in AC but not DC. So you also need innovation in regulation in this case.

Q: What about the grid operators, are they involved in this?

A: No, normally they are so heavily regulated they say ‘oh it’s not allowed’.  Also the advantage is at the customer level, it’s there that you have your energy saving, your renewable energy by solar, your copper saving. For the grid operator it’s more or less the same whether the grid is on AC or DC. They don’t see their advantage.

Q: And what about your final big paradigm shift?

A: Third, is the fuel cell car. Many car manufacturers are now working on this and it is being introduced in California, Germany, South Korea and Japan. The fuel cell car can produce electricity – it is an electric car with an electric motor – but the power comes not from the car’s batteries but is produced on board by a fuel cell converting hydrogen to electricity. The efficiency of this fuel cell is high, 60%.

The idea is that when this car is parked somewhere, it can also produce the electricity for your house, the grid, your office etc. Indeed every fuel cell engine, with about 100kW, can provide the electricity for 100 houses, not just one. The potential electricity production capacity of our cars – if they became fuel cell cars – is ten times that of our power plants worldwide. In Europe, we buy as much electricity production capacity in cars every year, as twice our power plants.

So we can replace our power plants by cars. You could build a parking lot for example, where you connect cars to a hydrogen production facility and to the electricity grid. When there is a surplus of electricity production from wind or solar, you produce hydrogen and store it in the tank of the car. When there is less electricity production, the car can produce the electricity that is needed.

Q: The car becomes both a store and producer of electricity?

A: Yes. And if you think about the development of autonomous driving, you could actually transport the car to where it is needed to produce electricity. Your car will drop you off downtown, drive to a car park to produce electricity and pick you up when you “whistle” for it. The car park can be on the city outskirts so this will also make a city cleaner and carless. We will have a totally different electricity-and-transport system.

Tesla dominates the public debate at the moment, but that’s not the main direction the car manufacturers are going

Q: But all the talk seems to be about battery-driven electric cars?

A: The car manufacturers are all talking about the fuel cell car. Tesla dominates the public debate at the moment, but that’s not the main direction the car manufacturers are going.

Hydrogen also lets you drive long distances: with 20kg of hydrogen in your car you can drive 2000km. And you can fuel your tank – that’s also a difference with a battery-powered car – in 1-2 minutes.

 

cover-green-villageQ: Your speciality is technological developments. Do you see any recognition among policymakers of these changes? In Brussels, the European Commission is talking about a redesign of the electricity market and a “new deal” for consumers, but this is all about smart meters, better information on electricity bills etc. The debate doesn’t seem to stretch to this level of system change. And how to decarbonise transport is a separate discussion all together.

A: These technological developments are happening but you don’t see them in the public debate about how a transition to a new energy system can be done. The public debate and policymakers don’t recognise these developments. It’s going much faster than they think.

Q: Is this a problem, does it risk slowing things down or even blocking them?

A: No. Of course regulation is a part of it, but the main problem is that a lot of these elements are not recognised by the energy sector itself. They don’t see the developments because they are not looking outside their sector. For example, the DC technology is very much driven by companies like Cisco and Apple because they are developing USB standards, for example. And they use DC in their data centres. USB becomes a standard not only for data transport but also for energy transport. Outside the energy sector there are developments that influence it a lot but they are not on the radar of either energy companies or energy policymakers.

These developments will happen, will come and will affect energy companies because it is the customer that is buying these things or using them. You see already Toyota and soon also Hyundai offering a fuel cell car with a plug that can provide electricity for the home.

The energy sector will develop outside of energy companies. For example, the smart meter will be surpassed by the Internet of Things

Q: Are there still energy companies in future? What do they look like?

A: I always say the energy company of the future will be a car leasing company for example. But you can also think that Google will do this together with the car companies. The energy companies of today need to change otherwise they will be out of business. I don’t see them thinking like this today. Traditional energy companies are already puzzled by the developments in renewables.

The energy sector will develop outside of energy companies. For example, the smart meter you mentioned, such a development will be surpassed by the Internet of Things. Every appliance will be able to measure its own energy consumption. Let’s take a fridge company – it will lease a fridge to you, including the electricity for it. The company then has a million fridges all over Europe and goes to trade on the electricity market. When there is an excess of electricity it turns the fridges up – so they cool a bit more – and when there is less, it turns them down and consumes less (then the price is also high). It’s nothing to do with energy companies anymore.

Q: As we move to a much more distributed energy system, what role is left for big, centralised infrastructure such as offshore wind farms and a high-voltage grid?

A: You can produce electricity from wind, solar etc. on a large scale. But it’s not necessarily an electricity network that will collect this energy. For example, I’m working with some of the world’s biggest companies to put wind turbines in the middle of the ocean where there are much higher wind speeds than in the North Sea. You cannot connect these floating wind turbines to land with a cable – that would be well above 1000 km and very pricey – so what we do is use the electricity to produce hydrogen, put it in a ship and bring it onshore. From there, it can go to fuelling stations for cars or to industry for products because hydrogen is also a chemical component for fertilizers for example.

I’m working with some of the world’s biggest companies to put wind turbines in the middle of the ocean where there are much higher wind speeds than in the North Sea

There will [still] be a high-voltage network but there is a decreasing need for it – you can do a lot on a local scale and you can do a lot of energy transport via ships and roads too.

Q: To what extent is energy policy shaping our future energy system?

A: You need energy policy. You need it to implement hydrogen fuelling stations in Europe for example. There is a need for a carbon price or something similar to stimulate the production of clean energy. On the other hand, some of these things will happen simply because companies and consumers produce and buy them. Without regulations. It’s not forbidden to connect your car to your house to produce electricity.

Q: How do oil and gas companies view these developments? Offshore production, hydrogen etc are not a million miles away from their expertise.

A: A lot of these companies are busy with their normal oil and gas reserves but you see for example Shell not opposed to hydrogen. First, it is also a fuel. Second, you can produce hydrogen from normal natural gas (and in the future through electrolysis driven by wind and solar power). In Germany, a coalition that is building 400 hydrogen fuelling stations consists of Shell, Total and car manufacturers.

Q: Are there are any other paradigm shifts you see coming?

A: I already mentioned the Internet of Things and the fridge example. Today we think we need batteries for flexibility but it can be done through demand too, and robotising. Today you plug in a vacuum cleaner and you need 1000 W at that time. In future, it will be a robot crawling around on the floor with a battery. The battery will be charged when the electricity price is low and you can still clean whenever you want.

Robotising and the Internet of Things will make all devices clever and demand much more flexibility. Every appliance, from your fridge to your car, will have chips, an internet connection and a battery.

And what does 3D printing mean for energy demand? You will use more electricity at home but less energy in the total system because of avoided transport and logistics. You need to transport your raw material of course, but that doesn’t cost as much energy as shipping all your finished goods from China for example. You will be able to produce personalised products at the location where you need them, on time. You will cut waste by only producing what you need.

 

20150907-green-villageQ: Does this mean Europe will de-industrialise?

A: Industry will develop these printers and designs [for printing] but if you want to make chairs or kitchen appliances etc. you will be able to do that at home.

I think there are many developments in the world today that have much more influence on the energy sector than the energy sector itself and also policymakers around energy.

Q: What is the timescale for all these system changes?

A: All these developments will happen, the only question is when. I think the fuel cell car will take at least another 10 years before it produces any major changes in the energy sector. But the LED revolution and Internet of Things will go much faster – I see them coming in 5-10 years already. The DC grid, I don’t know, I think you will see it develop very fast in certain areas – new towns in China for example – but in Europe I’m not sure. On the low-voltage level you will see some developments in buildings in the next 5-10 years but I’m not sure whether the grid itself will change that fast.

However, well before 2050, you will see large impacts of all these developments on the energy system.

Presentatie op TEDx Groningen

Met trots kan ik melden een presentatie op TEDx Groningen te hebben gegeven. Het thema was duurzame energie, met de focus op de inefficiëntie van onze huidige manier van leven. De deurbel is uiteraard voorbij gekomen, net als de mogelijkheden die onze auto’s geven om elektriciteit op te wekken.

Er is hierover ook een artikel verschenen in het Dagblad van het Noorden.

Artikel Autoweek: Auto van morgen – alles wordt anders (Dutch only)

In een uitgebreid artikel in Autoweek wordt het principe van je auto als energiecentrale groots uit de doeken gedaan. In de woorden van de schrijver:
Een brandstofcelauto is niets anders dan een elektrische auto met een eigen elektriciteitscentrale. Als die centrale alleen gebruikt wordt om de auto te voeden, dan zal hij het overgrote deel van de tijd nietsdoen. Zonde. Voor een groep visionairs aan de TU Delft aanleiding om te kijken of er meer mogelijk is met die brandstofcel. Hoe realistisch zijn de plannen van die Delftenaren?

‘Onze auto als elektriciteitscentrale’ (Dutch only)

We gebruiken onze auto voor ons werk, boodschappen te doen, vakantie, onze kinderen naar school te brengen of voor vriendenbezoek. De auto is voor velen een onmisbaar apparaat geworden, comfortabel en veilig, maar een energieslurper, eigenlijk niet meer dan een rijdende kachel. Wereldwijd wordt ongeveer een kwart van ons energiegebruik in deze rijdende kachels verstookt.

Wat is de energie-efficiëntie om ons in onze auto van A naar B te verplaatsen?
Een kleine berekening. De benzinemotor heeft een rendement tussen de 15 en 20%, waarbij benzine wordt omgezet in een draaiende beweging. De rest van de energie in de benzine wordt omgezet in warmte, dus 80-85% van de energie-inhoud van benzine moet worden weggekoeld. Nu moet die draaiende beweging via de versnellingsbak overgebracht worden op de wielen, dat gebeurt met een efficiëntie van 50%. Dus dan zitten we op ongeveer 7-10%. De auto ondervindt weerstand van de weg en van de lucht, die overwonnen moet worden en dit leidt weer tot energieverlies en zitten we op een efficiëntie van 3-5%. Veel analyses houden hier op, maar het is nog erger, want we verplaatsen ons in een auto van 1000 kilo om in mijn geval iemand van 100 kilo van A naar B te verplaatsen. Dus uiteindelijk komt de energieefficiëntie uit op minder dan 0,5%. Treurig toch!

Kan dat beter? Ja, en dat betekent elektrisch rijden. We zien nu de introductie van de elektrische auto die bestaat uit een elektromotor en een groot batterijpakket waar stroom in wordt opgeslagen. De rest van de auto is nog steeds hetzelfde. Maar zelfs dat geeft al een efficiëntieverbetering. De elektromotor heeft een efficiëntie van 95%, het op- en ontladen van de batterij een efficiëntie van 80% en het gemiddelde elektriciteitsopwekrendement in Nederland is 40%. Dus het gemiddelde motorrendement komt daarmee op 30% in plaats van de 15-20% van de benzinemotor. Dat is al een stuk beter, maar die elektromotoren kunnen uiteindelijk ook in de wielen worden geplaatst en dan heb je het verlies van de versnellingsbak niet meer. En als we dan ook nog in een auto van bioplastic gaan rijden, die de helft lichter is, komen we op een totale energie efficiëntie van zo’n 5%. Dit klinkt nog steeds niet veel, maar is uiteindelijk een factor 10 beter en betekent dus ook 10 keer minder energiegebruik.

Maar het kan met dat elektrisch rijden nog mooier: we kunnen er ons niet alleen veel energie-efficiënter in verplaatsen, maar we kunnen in de toekomst de elektrische auto met brandstofcel ook gebruiken om onze stroom mee op te wekken. De brandstofcel als automotor produceert elektriciteit uit waterstof met 60% rendement. Dat waterstof moeten we maken, bijvoorbeeld uit aardgas of biogas met een rendement van 75%. Maar dan hebben we nog steeds een elektriciteitsprodutierendement van 45%. Dat is beter dan het gemiddelde rendement van 40% van de Nederlandse elektriciteitscentrales. Als we dan in onze auto’s zo’n efficiënte centrale hebben, zou die dan niet, als de auto stil staat, onze elektriciteit kunnen produceren? Eens even uitzoeken, we gebruiken onze auto maar zo’n 5% van de tijd, de rest van de tijd staat die stil. Het vermogen van een automotor is tegenwoordig zo’n 100 kW. Hé, een auto kan makkelijk de elektriciteit produceren voor wel 100 woningen en dan kunnen we er ook nog gewoon in rijden. Wat als we nu een parkeergarage bouwen, waar we automatisch onze auto parkeren, aansluiten op een waterstofnet, het elektriciteitsnet en een warmtenet. We maken aan de poort van de parkeergarage uit aardgas of biogas waterstof, tanken onze tank vol zodat we met een volle tank uit de parkeergarage rijden. Maar als de auto toch stil staat, kan de brandstofcel in de auto ook elektriciteit voor het net produceren met een hoog rendement. Een parkeergarage met 500 auto’s verandert op deze manier in een elektriciteitscentrale van 50 MW, die met gemak 50.000 woningen van elektriciteit kan voorzien. Dus met een parkeergarage kunnen we alle woningen in de stad Delft van stroom voorzien!

Ongelooflijk, met één parkeergarage. Hebben we dan nog wel elektriciteitscentrales nodig in de toekomst? Het antwoord is nee. We kunnen met gemak met onze auto’s alle elektriciteitscentrales in Nederland vervangen. Er zijn in Nederland 8 miljoen auto’s die met elkaar zo’n 100 miljard kilometer per jaar rijden. Elk jaar kopen we meer dan een half miljoen nieuwe auto’s. Dus elk jaar zouden we 50.000 MW aan nieuw vermogen op wielen kopen. In Nederland staat aan elektriciteitscentrales zo’n 25.000 MW opgesteld. Dus elk jaar kopen we meer dan 2 keer zoveel elektriciteitsproductievermogen op wielen dan dat er is opgesteld. Elk jaar? Ja, elk jaar! En die auto’s zijn van u en mij. Als we die in de parkeergarage laten gebruiken voor elektriciteitsproductie dan hoeven we niet te betalen voor parkeren, maar dan krijgen we betaald voor parkeren. Zou dat niet mooi zijn?

‘Welcome to the Green Village’

One of my main activities at the TU Delft is to realize the Green Village:

“Creating a sustainable, lively and entrepreneurial environment where we discover, learn and show how to solve society’s urgent challenges”

That is the Green Village vision; a vision that we want to realize at the TU Delft, in the economic heart of the Netherlands. Innovative power that sets horizons for a new, sustainable, green and circular economy is of vital importance.

Find the complete plan and background for the Green Village in the attached document.

Interview in Shell magazine

A first, being interviewed by fossil fuel conglomerate Shell! They were kind enough to include me in an issue of their in-house magazine (called ‘Shell Venster’) which was dedicated to the future of energy.

In the interview I discuss the utter inefficiency of many everyday activities such as boiling an egg or driving a car, as well as the role I see of natural gas as a transition fuel. I conclude to state that sustainable energy does not need governmental subsidies, only a level playing field.

Read the interview online (Dutch only), or on the Shell website.
