Examination of Witnesses (Questions (128-139)

8 MARCH 2006

MR CHRIS HUNT, MR MALCOLM WATSON, MR SIMON BARNES, MR PETER STOKES AND MR ALEX BRUCE

  Q120  Chairman: I want to raise a point particularly with the PIA. Bluntly, you are at the liquid end of the market. In paragraph 1.7 of your evidence, there is a very interesting table in which the carbon dioxide reductions per hectare of land cultivated for a variety of biocrops indicate that the use of biofuels gives a poor return in terms of carbon dioxide saved compared with the use of biomass. I suppose I might say, if I was the government looking for an easy hit, I have an eight to one or seven or six to one ratio of saving of carbon. I might be more interested in encouraging the use of biomass than of biofuels. How do you respond to the findings of paragraph 1.7?

  Mr Hunt: It is very indicative of the statement we have put out in our response. Firstly, we fully recognise that road transport has to take its part in the reduction of CO2 and we are doing so through the RTFO. On the very simple sums, it is fairly clear that if you take biomass and use it for the generation of heat or displacing inefficient power generation, in CO2 terms, you get a far bigger bang for your buck than transferring that all the way down the supply chain to biofuel. That is a fact.

  Q121  Chairman: What does the SMMT think of that, because we are all getting terribly excited about the road transport fuel obligation and yet this table tells us we perhaps ought to be looking somewhere else?

  Mr Barnes: We are in a learning process here in the development of these fuels, particularly with reference to second generation biofuels where we know that the yields can potentially be significantly higher. First generation plays a role towards second generation biofuels, so we acknowledge the difference. However, we would not want that to mean that the opportunity for the industry to move forward in fuel technology is taken away from it to some extent, if that is not too strong a way to put it.

  Q122  Chairman: Is there a reason why we have not missed out stage one and gone to the second generation straight away, because if the returns are so much better why haven't we gone there now?

  Mr Barnes: The cost of developing that technology is still largely unknown and there is still work to be done on that. We are talking really about 2010 being an important time period for when that technology may well come along. There will always be a role ongoing, we believe, for first generation within the mix and the strategy. We see this very much as part of a strategic move to looking at how fuels are used in the road transport sector, moving forward to 2010, 2015 and ultimately towards hydrogen.

  Q123  Lynne Jones: Mr Hilton told us that, in terms of first generation fuel production, if you used waste agricultural products so you had part used for the biofuel and part for biomass, the implication was that would be as efficient as using the whole of the agricultural production for biomass. Would you care to comment on that and also what is the comparison between second generation biofuels and using the production just for heat and power?

  Mr Barnes: On your first point, it seems logical if you are harvesting the grain that you then have the opportunity to use the straw in another way.

  Q124  Lynne Jones: If you use the whole of it, so long as you are using both bits—

  Mr Barnes: Exactly. We would fully recognise that would be a sensible thing to do.

  Q125  Lynne Jones: But you would be for biomass production?

  Mr Barnes: Yes. I understand what you are saying. Growing the right crop in the right context has to be the start of this process. Moving on to second generation biofuels, we are talking about potential yields being three or four times higher, if not more, than first generations. The use of the whole crop becomes much more pertinent in the biomass to liquid process and you have the opportunity to do that.

  Lynne Jones: Would Mr Hunt care to comment?

  Q126  Chairman: Mr Watson wants to volunteer.

  Mr Watson: On the well-to-wheels basis that we have used, which is the equivalent of lifecycle analysis, we have looked at these options. If we take conventional wheat, we have the possibility of generating it using a variety of processes. There is a large energy demand in the process. If you meet that from burning straw, you get up to about 70/75% efficiency. If you take Brazil at the moment, they get up to about 85% efficiency. That is on a carbon saving basis. Those are both first generation processes and these would be the best examples. If you go to second generation processes, we are talking of 95%. You go that little further because you save a bit more carbon, which is the aim of this exercise. The second generation processes also give you a better yield per hectare so they have two advantages: more yield in terms of per hectare of land and also a bigger carbon saving, but they still do not quite manage the huge amount you get from power generation, as we have indicated in our paper.

  Q127  Lynne Jones: It is a huge amount so why not just concentrate on the biomass, the power and heat?

  Mr Watson: That is a choice for the government; it is not a choice for us.

  Q128 James Duddridge: This is a question to the Petroleum Industry Association. In the evidence you refer to the oil industry as still being relatively low cost. Given the volatility of the main oil producing regions and pricing of environmental costs of use of carbon and so on, is it realistic to consider oil as low cost as far out as 2030 compared to other renewables?

  Mr Hunt: On the studies that have been conducted—I refer to one particular study carried out by Concawe which is, if you like, an oil industry research body together with the European Union and the motor manufacturers—they have looked at a well-to-wheels basis on all the options. Without doubt, you find that whichever way you go in terms of absolute cost of CO2 abated biofuels have a cost and will have a cost for a consumer compared to fossil fuels. Fossil fuels are available and they will be available well up to 2030 and beyond. They are manageable; people are used to them. The supply infrastructure is there. The refining infrastructure is there. Therefore, I guess it is the game in town to beat. On that strand, anything we do on a bio content in some way, shape or form will be a cost to society on a well-to-wheels basis. Having said that, that should not stop you from doing it, but we have to recognise that cost. Your second question was about security of supply, I believe, on fossil fuels versus other alternatives. Even if we took the last 30 years or more the very worst global crises we have had within the region and outside—particularly if we took the Iran/Iraq war, for example—the downturn in production from that for a fairly short time was 8%. Therefore, if we applied that to the current UK strategic stockholding obligation, if nothing else happened, those stocks would last the UK something like 36 months. The disruptions that have happened, if you look back at the actuality of the situation, have been fairly modest. Furthermore, if we took UK refining as an asset, something that we should use to give us the ability to flex and generate our road transport and other fuel needs from a variety of sources, there are probably something like 27 different sources of crude oil around the world. We compare that to where some of our biomass might be coming from. We probably have more options open on crude oil supply than on biomass necessarily.

  Q129  James Duddridge: My analysis might be simple. Forgive me if it is and correct me. Demand over time, if we assume that that is static for energy usage and take almost fossil fuels and renewables as two products, if they are two competing products in a market economy, there will be a point as fossil fuels diminish in volume at which there is a cross over if you graph it out in terms of price, the renewables being better value for money. Have you a view on when that supply and demand graph date is projecting out?

  Mr Hunt: On the supply perspective for fossil fuels, we are not going to run out. It is as simple as that. We have reserves now of conventional fossil fuels. There are heavy tar sands and various others that will eke us out well into the future.

  Q130  James Duddridge: It is an absolutely limited resource so even if we are talking 200 or 2,000 years presumably there is a number of years?

  Mr Hunt: At some point. I do not have a precise figure for that but it will certainly see me out. That is for sure.

  Q131  James Duddridge: I was worried about beyond that and beyond everyone.

  Mr Hunt: You are then looking at the development of the alternative fuels that are coming on behind which will be the use and application of things like hydrogen and where we generate that from renewable sources. The message was the imperative to move towards a lower carbon economy is not because you are going to run out of oil; it should be for the right, considered reasons going forward.

  Q132  Chairman: Everybody keeps talking about hydrogen. Mr Barnes dropped it in as a little sweetener to his initial opening comments. How realistic is hydrogen transport? If I look towards our two motor manufacturers as part of your delegation, how far away are you from having a car available to the European customer that runs on hydrogen?

  Mr Stokes: You have to acknowledge that there are two routes for hydrogen. One is in a conventional internal combustion engine and one is the much vaunted fuel cell. I think it is fair to say the fuel cell has been a perpetual 10 or 20 years away for as long as I can remember.

  Q133  Chairman: It is a bit like the TB vaccine.

  Mr Stokes: Exactly. That technology, depending on who you talk to, some people feel is further along the curve. Some people feel it is further back. It still seems to remain around the 20 year mark but an awful lot of work is going on there. In terms of the internal combustion engine, some manufacturers are looking at that and I believe there is a hydrogen filling point being set up in London somewhere so that a manufacturer can bring product in that will run on that. There are two developments but that is not renewable hydrogen; that is conventional hydrogen.

  Q134  Chairman: How near are we to having a vehicle that can run on it? It is all right having a filling point but I do not think you will have very many customers in the United Kingdom because, unlike California, I have not been made aware that there is a fleet of cars knocking about. Maybe Mr Bruce is going to shock us and tell us there are some.

  Mr Bruce: We do already have vehicles available running on fuel cells. The issue is more in relation to the range of the vehicle, the durability of the fuel cell and the cost of producing the fuel cell on a commercial basis.

  Q135  Chairman: You are saying that hydrogen at the moment is more likely to be a fuel cell alternative than using hydrogen as a feedstock directly as a point of combustion, for argument's sake?

  Mr Bruce: Different companies are pursuing both options. From General Motors' perspective, we are investing heavily in fuel cell technology specifically and looking to try and address those specific issues related to the cost of production of the fuel cell on a commercial basis, the range and storage of the hydrogen on board the vehicle. Those are the main issues that need to be addressed in order to make it commercial.

  Q136  Chairman: To put what we are doing into perspective, our previous two witnesses made it very clear that if a biofuels industry was to become viable they would have to have an element of certainty with reference to the investments that would have to be made. What kind of a timescale—I appreciate you cannot be exact to any one year—are we talking about? Are we talking 5, 10, 15 years? You said it is always 10 years away but in terms of hydrogen powered vehicles is it always that speck of light away in the distance so we do not need to worry about it or is it getting nearer so that we can say, "Yes, we could well see some vehicles for sale in, say, 10 years' time"?

  Mr Bruce: You could well see vehicles in that time frame but whether they will be affordable for everybody is going to be the big question. That is the fundamental issue in relation to hydrogen fuel cells, being able to produce them for the mass market on a commercially viable scale. That is really what we are grappling with in relation to fuel cells. For the foreseeable future, 10 or 15 years, you will see continued demand for biofuels both first and second generation.

  Q137  Mr Williams: If the RTFO target of 5% by volume of inclusion of biofuels was achieved by 2010 it would be equivalent to a reduction of one million tonnes of carbon dioxide or taking a million cars off the road, but as the inclusion rate at the moment is only 0.3% do you think it is going to be in any way achievable?

  Mr Hunt: UKPIA and its members are and will be committed by our government by an obligation to move towards that, from the work that we have been doing as UKPIA, the involvement we have in the RTFO committees, working with biofuel producers. For example, the indicative figures that we are hearing in those meetings, if we took biodiesel as an example, are that something like a 3% availability of total UK demand in 2008-09, rising to 4% in 2010. For ethanol you have sources like Brazil outside of the country. From a UKPIA point of view, what we need to make fairly substantial investments in bringing these fuels to market, always being very mindful of the imperative for quality and maintaining that quality—I am sure my colleagues in the vehicle industry will back me up on that—is a workable scheme and a well thought through process. Biodiesel will probably be easier to bring to market but we still need investment in tanks and necessary equipment at refineries and other points to do that. Ethanol is somewhat of a different animal. That will require a far more significant investment because you can only effectively blend that product in with standard petrol at the terminal, very near to the consumer. You need investment in tankage, blending equipment et cetera at those terminals and further down the chain there are issue in terms of the service station itself. Ethanol does pick up water. It tends to pick up dirt as well and the experience in Germany has said we have a fair bit of work to do to ensure that the service station is geared for receipt of that product. That gives us some things to think about over time. Of the 10,000 service stations in the UK, oil companies own and operate about 2,500. There are 5,000 independent service stations that need help in getting towards that so the investment cycle for ethanol is going to be longer than that for biodiesel which is why we have said in our responses to the Treasury in particular that the interim target should be set as achievable. Otherwise, the consumer will be paying a penalty for a CO2 reduction which is not being made.

  Q138  Mr Williams: Are you saying as the rate of inclusion increases so the investment by retailers at the petrol pump in the higher quality storage and distribution will increase?

  Mr Hunt: No. What I am saying is it is the speed at which you can make the investment. For example, if you take the investment we need to do on ethanol at major terminals around the UK, you can imagine the sorts of discussions we are going to have on planning permission following Buncefield, about putting in additional tankage for highly volatile products. It is a question of availability of the product and the infrastructure to take it. They are the only limiting factors really. It is not a lack of will.

  Q139  Mr Williams: Would the motor manufacturers like to comment on whether the target will be reached or not by 2010?

  Mr Barnes: Last year we had 0.3% of biofuels content in the UK. We are manufacturing cars now to a 5% standard, so towards 5% that is not an issue. The car parc today can run on that percentage of fuels. Going beyond 5%, we certainly need the European CEN standard on fuel to be established as soon as possible to enable us to start manufacturing towards that higher percentage. The introduction beyond 5% also raises some slightly different issues at the point of dispensing and potentially with informing the public that there will be vehicles that will run on 5% and on 10%. Up to 5%, fine, but beyond that needs further consideration.
