Vehicle Technology and Aviation Bill (Fourth sitting)

Kit Malthouse Excerpts

Thursday 16th March 2017 Public Bill Committees

[Andy McDonald]

Yes, it did, several times. It is still running, but it is partly rusted to death. The point is that the measure fits in with the new modelling and is entirely consistent, but it must be underpinned by the obligation to take reasonable steps to update the software. Otherwise, we have difficulties. The amendment would not put the manufacturer behind the eight ball if people are determined to avoid updates or interfere with them—far from it—it just sets out a framework that there should be an obligation on them. I recommend the amendment.

New clause 9 is directly related to the amendment. It requires the Secretary of State to make regulations preventing automated vehicles from being operated in automated mode on public roads unless the software for that function is up to date. We addressed the importance of updating earlier in the Committee, so I will not repeat those arguments, but I underline the seriousness of ensuring that the software is up to date. Out-of-date software can present safety risks. Because of the issues surrounding liability, it should not be beyond the wit of man or too difficult to prevent un-updated vehicles being on our roads, and it would make sense to do that. If a vehicle had a serious mechanical fault that could endanger the driver and others, we would not allow it on our roads. It makes sense that an automated vehicle would similarly present an increased safety risk if its operating system was not updated.

[Kit Malthouse (North West Hampshire) (Con)]

I find the hon. Gentleman’s new clause a bit absolute. My experience of updating software is that some updates are critical and some are quite nice to have and may not relate to safety. For instance, with an autonomous car, there might be a software update that tells the car to take a particular angle of bend at a slightly more comfortable speed. That has an impact on comfort; it does not necessarily have an impact on safety. My reading is that the new clause would rule out that car from being authorised to be on the road unless it had that update.

[Andy McDonald]

I think there is a difference. The new clause says that the car has to be up to date and fit with the current requirements, but it does not say it has to be the latest software. A software product may have several versions—we are now getting into nice-to-have mode and additional facilities—and the one someone has in their car may be safe and up to date without being the latest. What I am trying to address with the new clause is software that is updated on safety grounds and essential changes to the programming.

Without the new clause, people would be able to take un-updated vehicles on to our roads, either by accident or on purpose. Insurance companies would surely factor the increased risk into premiums, which would be higher as a consequence. For reasons of affordability, it would be sensible to include the new clause in the Bill.

The amendment proposes that the Secretary of State should introduce regulations to prevent an automated vehicle from being operated on public roads unless the application software relating to the vehicles’ automated functions is up to date—not the latest available, but up to date. From a technical standpoint, that should not be too difficult to achieve. Most people with a smartphone or computer are likely to have software that prevents it from being used until it is updated; I am not struck by any reason why a similar mechanism could not be included in automated vehicles. By preventing un-updated vehicles from being used, we would achieve safer roads and cheaper insurance.

One primary benefit of AVs is that they reduce the likelihood of human error, yet one of the few areas in which scope for human error remains—the responsibility for ensuring that software is updated—would not be addressed, even though it would not be difficult to do so. The new clause would address that. I trust that it will have the Committee’s support.

I am well aware that hydrogen possibly has a disadvantage as a fuel—what I believe is called a low calorific density—but the point for me is that some of us really enjoy our driving. We have started to forget that some of us love our motoring—we enjoy our motoring and our motorcycling —and some of us might wish to preserve vehicles that one day may be considered historic: vehicles with an internal combustion engine. I would like to leave open the possibility of converting those magnificent petrol engine vehicles to run on hydrogen and to use hydrogen refuelling stations. In order for the Bill to apply in such circumstances, we need to leave out “electrical”, so that a hydrogen refuelling point and so on is possible. The capability of being driven by power derived from hydrogen is a simple proposition, and we can simply leave open greater scope for innovation, which might assist those of us who love our motoring.

[Kit Malthouse]

I want to speak in support of the amendment, not least because of something we have to bear in mind during the passage of the Bill, which is the pace of change of technology. It is likely that the move to electrical vehicles, whether battery or hydrogen, will be very fast over the next two or three decades. We will be left with the legacy of an enormous number of internal combustion engine vehicles—millions and millions of them.

The ability to convert a petrol-powered car to hydrogen internal combustion is quite easy—it is not that hard to do—and in fact dual fuel is possible with two tanks, one of hydrogen and one of petrol, which would allow someone to compensate for the sparsity of hydrogen refuelling facilities. Having that ability for non-electrically driven cars to refuel would mean that instead of having millions of cars that people need to recycle or dump, and whose value will suddenly fall off a cliff as the new technologies come through, they can opt to convert them to internal combustion driven by hydrogen.

As my hon. Friend the Member for Wycombe said, we would therefore be able to preserve some of those historic vehicles and, frankly, to extend the life of existing petrol vehicles, which would be more environmentally friendly than simply dumping them.

[Mr Hayes]

The essence of the argument of my hon. Friend the Member for Wycombe, which reflects the exchanges that we enjoyed in the evidence sessions, in which a number of Members played their part, is to query whether the Bill is insufficient in respect of fuel types such as hydrogen. At this juncture, I perhaps ought to make it absolutely clear that the Bill is technology neutral. We recognise that a number of technologies are emerging. Given the scale and nature of the change we are enjoying, it is not yet clear which will become pre-eminent, but it is certainly true that there is investment in hydrogen. That was pointed out by a number of my hon. Friends during the evidence sessions. In particular, my hon. Friend the Member for North West Hampshire has taken a keen interest in such matters for a considerable time.

Raising the issue of extending the definition of a hydrogen refuelling station is important. The proposed redefinition away from

“a device intended for refuelling a vehicle that is capable of being propelled by electrical power derived from hydrogen”

to one that includes hydrogen-fuelled internal combustion engines, however, is more challenging. I will explain why. I recognise that there are all kinds of ways of propelling vehicles. As I have said, a number of those would have a beneficial effect on emissions, in essence producing zero tailpipe emissions, just as electric cars do. I also note what my hon. Friend the Member for Wycombe said about the adaptations that could be made to an internal combustion engine. I did wonder what my right hon. Friend the Member for East Yorkshire would think of that, but he made no move or sign. There was no change of expression on his face, but I could not help wondering—

--- Later in debate ---

[Mr Hayes]

Whether I was aware of that or not, I am now. It is certainly the case that the adaptation of an internal combustion engine to allow it to use hydrogen varies according to the character of the vehicle. That is partly dependent on the vehicle’s age. In many cases, it produces only a limited advantage in respect of emissions. It is not true that adapted hydrogen vehicles always produce as efficient a result as vehicles that are designed to run on hydrogen fuel cells. At least that is what I am advised, but I can tell that I may be about to obtain different advice from my hon. Friends.

[Kit Malthouse]

I am hesitant to give the Minister a chemistry lesson, but the combustion of hydrogen does not produce anything like as much CO₂—no carbon is involved, necessarily, in the combustion of that—and it produces significantly less NOx emissions, so there is a huge advantage in the internal combustion of hydrogen over that of a carbon-based fuel, such as petrol or kerosene.

[Mr Hayes]

As I said, I am always prepared to receive advice on these matters. I acknowledged in advance that my hon. Friend has great expertise in this field, so far be it from me to flatly disagree with him, but perhaps I am about to get another chemistry lesson.
