[The Chair]

Thank you very much. Alan Brown.

Q On the smart grid that we are aspiring to, the panel has already alluded to the fact that they think smart charging will come by market, but there is a lot more that the Government need to think about in the wider energy mix, because there is also decarbonisation of heat and further decarbonisation of electricity. There is the future scenario of an influx of electric vehicles, but a whole lot else is going on in the energy mix as well. The point is to make sure that is all captured to get the smart grid we need.

Marcus Stewart: We see smart charging for electric vehicles as a key starting point for that. You can get smart technology in your home today—smart thermostats, for example. Commercial premises have smart air conditioning and smart lighting that help to balance their load and can provide services back to the grid today. An electric car will be the biggest asset in the home that uses energy, unless you convert to heat as well, and that will have a big impact on the system. Making that smart at the start is the right thing to do.

Suleman Alli: It is a bit like the concept of offset mortgages in the financial services sector, where you pay your salary into an account and that offsets against the mortgage interest you pay. We are starting to see a new business model emerge where people say, “We can give you price certainty or reduced energy bills if you plug your vehicle in and allow us to provide services to the wider network operators or the system operators.”

I think the market will innovate and start to provide those services. We are already seeing that in the internet market, for example. Some of the trials we are doing will look exactly at that area. It is intuitive for us to think that if you have an electric vehicle you are going to go home and plug it in straightaway. The research that we have undertaken shows there is a diversity. When you have a large population of EVs, not everybody goes home and charges at the same time. In fact, we have seen about 30% of the impact materialise—of the capacity of charge that has been installed. There is an element of diversity that we incorporate into our planning that is based on evidence from the trials we have undertaken.

[Alan Brown]

Q Can I ask one more question about the model scenarios? You are modelling how many vehicles might be coming in, among other things. Is that based on mass volume modelling, or does it look at existing restrictions in the network and at where the uptake might be? Clearly, uptake depends on the roll-out of the charging system and some local authorities in some areas are much more at the forefront of that than others. That potentially impacts their work as well.

Marcus Stewart: I could talk about how we would do that. The primary reason to do it is to understand what network capacity expansions and reinforcements are needed on a national level. We will have different assumptions for different locations, where we have evidence. For example, there may be clustering in cities that we will make assumptions around. I imagine that the DNOs will look at similar things for their networks as well. We look at it on a spatial basis; it is not just a single-number basis.

Suleman Alli: What we are looking to do, particularly with electric vehicles, because there is a lot of data available out there, is try to apply much more advanced analytic techniques. For example, how can we marry up Land Registry data, which gives an indication of people who might have driveways, together with Acorn data about people who might be more able to buy an electric vehicle, together with data on charge points, in order to get a better and more granular view of our network? That is what we are doing at the moment to improve our planning.

[Alan Brown]

Q So it is a live, ongoing process.

Suleman Alli: Absolutely. I do not think we can ever say we are done.

[The Chair]

Thank you. We have a lengthening list, so let us have one question and one answer.

--- Later in debate ---

[Clive Efford]

Q I will leave it there. One last question on what is driving this forward—that was not an intentional pun. Is it the desire of companies that employ large workforces that drive vehicles which are striving for automated vehicles, or is it the demand from the public, which wants to sit comfortably behind the wheel and not have to think too much for long journeys?

Quentin Willson: It is driven, I guess, by the fact that there is a huge world of opportunity here and that is predicated on the fact that people do not like driving anymore—there is congestion, it is expensive and it is difficult—and on the rent economy, whereby you summon an automated car on your smartphone and it comes to your door. When you look at the research, that is very attractive to the public. The golden era of getting pleasure from driving cars has gone, and I say that with some regret, but it is a fact. There was a survey by Catapult in Milton Keynes which asked this question: if you were to replace your current car with an autonomous car—we are not going to tell you what it is or what it looks like—would you be prepared to change to that autonomous car? Some 58% said that they would change to the autonomous car without knowing what it was, simply because of the liberation of not having to make those decisions and sit impotently in snarling traffic. It is partly driven by commerce and partly by the public.

[Alan Brown]

Q Is the Government’s target of 2044 for zero-carbon new cars ambitious enough?

Quentin Willson: I sat before this Committee a year ago and was broadly optimistic about the short and medium-term future of electric cars. I think Michael Gove’s announcement in July, coupled with Sadiq Khan’s T-zones and ClientEarth’s relentless pushing on air quality issues, has terrified consumers. It has wiped probably £30 billion off the value of diesel cars. Lease companies are now looking at a collapse in the residual values of the cars that they lease to consumers on personal contract purchase. We are looking at a real issue in the short to medium term.

The consumer now feels that he or she cannot buy a diesel car; we have seen sales of diesel cars absolutely collapse over the last quarter. They are feeling, “Right, I’ve got to buy an electric car.” We need to manage their expectations. I am quite concerned that people who rely on one car as the family vehicle will go out and buy, like me, a second-hand Nissan Leaf for £10,000. That is great, but we must understand that those cars’ ranges are nowhere near viable for an everyday, use-it-all-the-time car. They are a wonderful urban solution, but long journeys—anything more than 100 miles—are really difficult. I came down here in an alternative car; I had to leave my Nissan Leaf at home, because getting here would have required three stops to charge.

It is about managing consumer expectations. Otherwise, this whole thing will go horribly wrong. The new Nissan Leaf, which I saw in Oslo last week on its launch, has a quoted official figure of 235 miles to one charge, but the Nissan engineers tell me that in reality, it is 175 miles for everyday driving. If you drive that car on the motorway at 70 mph, that will fall to about 130 or 140 miles. The technology of the lithium ion battery still has some considerable work to do.

Again, it is all predicated—the mass adoption of electrification in the short to medium term—on having better battery density, maybe of alternative materials such as graphene, and a very robust charging infrastructure network. I am not talking about on-street chargers; I am talking about charging hubs like petrol stations, with 20 rapid chargers that can charge 20 cars in 40 minutes. That is the only way that mainstream consumers will be able to do any form of distance. They are wonderful for town work, but if you are doing more than 100 miles, you are still compromised.

[Alan Brown]

Q To follow on from that, it is interesting what you say about the conundrum of managing consumer expectations so that people do not buy a vehicle that might not suit their purposes. Going forward, when the technology allows, given that it was UK Government policy that drove the flux of diesel vehicles, does there come a point when the Government should incentivise a diesel scrappage scheme to get that mass ownership?

Quentin Willson: I would rather spend that money on the NHS. Here is an irony: we talk constantly about air quality, but in the MOT, there is no proper smoke test, although it is called a smoke test. The particulates come out the back, and the MOT examiner will fail the car if it loses rearward visibility. If you cannot see out the back when the car is accelerating, it fails. That is why you see all these cars puffing out black particulates. If we stiffened up the MOT with a proper particulate test and then automatically scrapped these cars, a lot of which are old and worn out and pollute much more than we realise, we would not have to finance a scrappage scheme. Consumers would realise, “This car is knackered; it’s got to go anyway.” But at the moment, there is no mandate against either petrol or diesel cars that really pollute.

Again, on the air quality debate, I am not sure that we will solve urban air quality with electrification alone. Even though we get massive amounts of people driving electric cars in cities, we still have 30% of particulate and NOx from industrial combustion, 20% from domestic combustion, 14% from ground machinery such as diggers, trucks, dumpers and cranes—these are London Assembly figures—5% from HGVs, 8% from vans and 9% from buses. We do not know the contributions from aviation and shipping. Certainly in London, with 20 million tonnes of stuff coming in on the Thames tidal, the fact that that is not even quantified worries me greatly. We do not want the unintended consequences of this not to affect air quality significantly and, in the meantime, blow the GDP of a generation while doing it. That is my worry. The fact that we do not know enough about this, and that it is being pushed and pushed and terrifying consumers, is of great concern to me.

[The Chair]

Thank you for that admirably clear answer.
