Select Committee on Environmental Audit Minutes of Evidence


Examination of Witnesses (Questions 68-99)

DR JEFF CHAPMAN, MR SARWJIT SAMBHI AND MR RUPERT STEELE OBE

11 DECEMBER 2007

  Q68 Chairman:.Good morning gentlemen, welcome. Do you just want to introduce yourselves so that my colleagues know exactly whom you represent?

  Dr Chapman: I am Jeff Chapman. I am Chief Executive of the Carbon Capture and Storage Association. This is an industry association. We have 53 member organisations, all of whom are interested in the business of carbon capture and storage. They cover the oil and gas sector, the power sector, suppliers, contractors, consultants, law firms, academic institutions and anyone with a business interest in carbon capture and storage.

  Mr Sambhi: Sarwjit Sambhi from Centrica. I head up the power business for Centrica, that is conventional power generation and renewables, mainly offshore wind.

  Mr Steele: Rupert Steele, Director of Regulation at ScottishPower. We are one of the UK's big six integrated energy suppliers. Obviously we have significant interest in Scotland, but England as well.

  Q69  Chairman: Thank you very much. How important is CCS to achieving the global emission stabilisation targets?

  Dr Chapman: The first thing is that CCS can make a massive contribution to achieving global targets. The world is expected to increase its dependency on fossil fuels over the coming years. When you have places like China which is building at least, the UK's total capacity in coal-fired power plants every year, this is a major problem. Normally everyone thinks of coal as being the big issue. Well it is, but I would just like to draw attention also to non-conventional fossil fuels. For example, the tar sands in Athabasca, Canada and developments of natural gas that contains CO2. Athabasca tar sand costs about 30% more energy just to produce synthetic crude oil and as a result of that Canada are 300 million tonnes a year above their Kyoto commitment and that is the equivalent of, let us say, 15 Drax power stations; it is very big. So these countries have to consider carbon capture and storage. The IEA world energy outlook is suggesting that global emissions look set to rise by at least 30% by 2030 and the world simply cannot meet its climate objectives without a very large proportion of carbon capture and storage.

  Q70  Chairman: How quickly do we have to get it out there, if we are actually going to make a proper impact?

  Dr Chapman: We have to get on track now. These projects are very long timescale in development and, if you do a bar chart from the time you want it to now, you should have started a long time ago.

  Q71  Chairman: Are we remotely near having a chance of actually getting on track?

  Dr Chapman: We could be because, certainly in the UK and in certain other places, there are projects that are under development that look to begin to start delivering or could be beginning to start delivering at about 2012. If we can accelerate that programme in a similar manner to the "dash for gas" that took place in the 1990s, we could make a very big impact in the second half of the next decade, towards 2020. We could have a lot of capacity on the ground by 2020 and certainly an awful lot of capacity in the 2020-2030 decade. It all depends on policy.

  Q72  Mr Chaytor: May I just pin you down on the figures? There seems to be a contradiction between what the Government said in the pre-budget report, which suggested the demonstration project could deliver savings of 0.7 million tonnes by 2020, and what was said in the White Paper, which was a figure of between 1.1 and 3.7 million tonnes. From our point of view this is hugely confusing. What do you expect the demonstration project to be able to deliver by 2020?

  Dr Chapman: The demonstration project itself, if you assume that it is 300 megawatts, then that 300 to 400 megawatts is going to deliver about two million tonnes. Whether or not you say that is CO2 abated, it is certainly the CO2 emissions that will be collected and stored, but that does not necessarily relate to what is abated because it depends what is substituted on the generation system. If that were nuclear, that would be nothing. If that were gas, that would be half of that.

  Q73  Mr Chaytor: Within your capacity, within the demonstration project, your figure is about two million tonnes.

  Dr Chapman: Yes.

  Q74  Mr Chaytor: In the longer term, the Stern Review talked about the capacity to reduce total emissions by 90% in fossil fuel power station through carbon capture and storage. There is a figure here from the Government when the demonstration project was launched last week suggesting that about a third of total UK electricity could be generated with the use of carbon capture by 2020. Do those figures sound right?

  Dr Chapman: They could easily be. At the present time there is under-development and I have to say that because of the announcement some of these projects are rather on the shelf, but at the present time there are at least 10 projects under development in the UK that could have carbon capture and storage and those projects are all coal; they could save well over 50 million tonnes of CO2 between them. When I say "save", I am being very advised about that because of an argument I just made about what it displaces.

  Q75  Mr Chaytor: How can you be so sure of these 10 projects that could benefit from carbon capture and storage when the demonstration project is not off the ground yet? Surely you have to get the demonstration project going before you can be sure as to how widely it could be disseminated?

  Dr Chapman: That is right. Four of those projects would be pre-combustion capture and six of those projects are post-combustion capture. The demonstration project, as we know, is post-combustion capture. There are things that need to be proven in post-combustion capture and, in the end, it is a commercial decision on behalf of suppliers as to whether they will supply and guarantee projects of the size of 300 megawatts or 1,000 megawatts even. What I will say is that on the pre-combustion capture the developers of the projects have been going into this with their eyes open, they have been spending tens of millions of pounds on feasibility for these projects and we are talking about large companies; companies like ConocoPhilips, companies like BP, Shell of course. If they were not confident in their technology, they would not have been spending that amount of money. If you look at BP, for example, they have specifically created a company in association with Rio Tinto called Hydrogen Energy whose sole purpose is to produce hydrogen from coal from which to generate power and into the future to become part of the hydrogen economy. Those companies do not go into that if they are not confident of the technology that goes along with it.

  Q76  Joan Walley: I am just looking at the UK really and the 2050 carbon budget. Can you just give us a bit more information about how important CCS is in respect of meeting those aspirations in respect of the carbon budget for 2050 and the timescale between now and then and what needs to be put in place?

  Dr Chapman: Of course I do not have access to the kind of modelling that the Government do, but it is quite clear that we need everything that we can do, "every tool in the box" as Sir David King would say, to deliver these commitments.

  Q77  Joan Walley: You say you do not have access to the modelling that has been done by Government. One of the things that we wanted to ask you to share with us was what modelling you were doing. How can you be doing the modelling, if you do not have access?

  Dr Chapman: As an association we are not doing any modelling.

  Q78  Joan Walley: So who is doing the modelling?

  Dr Chapman: As far as I know, just the Government and possibly some other commercial organisation for the benefit of their, perhaps, consultancy.

  Mr Sambhi: May I offer a perspective on that? In terms of the UK, there are two time dimensions to the role of CCS. One is against the longer-term aspirations, whether it is the specific emissions reduction target that the Government have set or the Stern Review requirement or the view that you have to get below say 550 parts per million of CO2 by 2050. Our analysis, and this is an analysis that other consultancies have done as well, suggests that if you are to reach that, after you have exhausted the initiatives that are low cost such as demand-side energy efficiency initiatives, after you have exhausted the resources in offshore wind, you get pretty close to needing to invest in clean coal. Specifically, to meet the government aspirations clean coal has to be in the mix. The second dimension is perhaps more medium term. When we look at the need for new power generation in the UK, one can model a number of scenarios but there is a scenario which suggests that by the middle of the next decade, there is a need for more capacity beyond those projects that have already been committed such as Lanage and Marchwood which are gas projects. In terms of what can fill that gap, when you look down the list of options, nuclear new build does not really fit in that time horizon because the earliest you could get a nuclear project off the ground, even if you started now, would be 2018-2020, then you look at the other options, more gas-fired power generation or unabated coal or coal that requires carbon capture. Again, unabated coal does not sit well alongside the emissions reduction targets that have been set.

  Dr Chapman: To put the challenge in perspective, if you draw a straight line trajectory from now to 2050 and you take 60% and not the 80% target that is being mooted, then basically you have to reduce emissions by eight million tonnes every year, year on year on year on year; from now to 2050 you have to reduce eight million tonnes of emissions. To put that in perspective, the entire UK wind industry at the moment is only abating just over five million tonnes a year. It is a huge programme and of course one CCS project could achieve five million tonnes anyway.

  Q79  Joan Walley: Just to pursue that a little bit more. With what you were saying about the Government doing the modelling, they do not seem to be doing it in conjunction with your business projections and so on. Given what you just said about having to reach where we need to be for the carbon budget by 2050, what I need to have some idea of is what lobbying you are doing with Government to get them to take account of what your projections are, otherwise you are all going to be on separate tracks, are you not? It is not really going to come together in terms of how we go about achieving where we need to be.

  Mr Steele: We are broadly content with the kind of projections that the Government have come out with, that look to us about right, that coal will be a significant part of the mix going forward, not least because it is so widely dispersed and in politically more stable areas of the world. So we are comfortable with the kinds of use that the Government have come out with and the thought that CCS could produce about a third of the emissions reduction stretch that we will need to achieve. We are clear that a good amount of work needs to be done to actually make this happen and so we are very supportive that the Government have now bitten the bullet and got the process going with this competition. We need to do a lot of work to get ourselves actually operational as a country with carbon capture and storage, but there is huge potential to make a real difference.

  Q80  Joan Walley: If CCS is not developed in the way that you would like it to be, then how long do you think the UK will be able to maintain the existing fossil fuel generation?

  Mr Steele: Obviously the way we work with carbon in the major sectors is through trading. The issue will then arise as to whether the best economic decision is to generate the electricity from coal in the UK and abate somewhere else or generate from something else in the UK and take the abatement in the UK. If the price of carbon is high and we do not have carbon capture and storage working, then it is going to be increasingly difficult for coal-fired power stations to generate cost effectively and that will squeeze down the amount that they generate. It is obviously very difficult to project how that will work.

  Dr Chapman: If I can go back, you asked what lobbying we were doing with Government and certainly a couple of weeks ago I had a meeting with both Malcolm Wicks, the Energy Minister and Phil Woolas, the Environment Minister, at the same time and this is really what I said to them. The UK Government have taken a tremendous initiative to sort out the regulatory side of CCS. The only thing which stops business investing in carbon capture and storage is policy and the policy breaks down into two areas: one is the regulatory side of policy and the other one is more the financial side of policy, the incentive to go ahead with it. The Government have made tremendous efforts and are leading the world in the development of policy, so all compliments to the Government for doing that. The demonstrator project is really a tremendous initiative and does show leadership in the world because it is at least a measure comparable with what the best of other governments are doing elsewhere. Yet, if we are going to meet our climate objectives, we need to do a lot more than that. There is an accelerating pace of development elsewhere in the world and we will inevitably be upping our game in this area even just to keep pace with the rest of the world, as well as to save our own emissions.

  Q81  Joan Walley: The point you are saying needs more work on it, is the regulatory aspect of it, is it? The area that you say more work is needed on is the regulatory aspect.

  Dr Chapman: No, more is needed on the financial side, on the incentive side. The regulatory aspect will be sorted out very soon. The UK is leading the way. In European policy there will be a directive on CCS that will come into operation very soon which owes an awful lot to the groundbreaking thinking that has been done in the UK.

  Q82  Martin Horwood: I share Joan Walley's surprise that you have not been doing very much modelling. If you are going to try to justify, certainly if you are going to ask for more investment in this from Government, you need to present a very strong business case and surely the modelling has to be crucial for that. Even the political parties are attempting simple modelling.

  Dr Chapman: I have to say that our member companies do a lot of modelling. You have to bear in mind that we, as an association, are very young. We have only been in existence a year and a half and we have very limited resources so far.

  Q83  Martin Horwood: But you have the resources of your member companies in a sense.

  Dr Chapman: Yes, we have.

  Q84  Martin Horwood: May I pick up something Mr Sambhi said as well? I share your analysis that this is a crucial part of the overall carbon budget and we really do not have a chance of meeting it without that, but you suggested that, as a transition technology, while we are waiting for renewables to come up to speed, it was actually a better option than nuclear in terms of timing and potential. Did I hear you right?

  Mr Sambhi: I will answer that, but may I just pick up on the modelling. We should not get too hung up on the question as to whether enough modelling is being done. There is and I will explain what some of the uncertainties are in a moment. To answer your question, I was not saying that clean coal is a better option than nuclear. I was referring to the next decade when there is a need for new generation, say around 2015. New nuclear cannot be considered in the mix because, even if we started now, we could not get a new nuclear plant up and running until towards the back end of the next decade.

  Q85  Martin Horwood: But you think carbon capture storage could be viable well within that timescale presumably?

  Mr Sambhi: Yes. Going back to the point that Jeff made, if we had the financial support mechanisms in place and we were able to commit to investing in a new clean coal project, the one that we are developing up at Teesside, Eston Grange, could be ready by the 2013 time period.

  Q86  Joan Walley: May I just ask what you mean by the financial support mechanisms in place? What would they consist of?

  Mr Sambhi: In terms of going back to the question of what we have modelled, when we model the economics of a clean coal project, there are several uncertainties. One of the two biggest ones is how much it costs to build a clean coal project. The project we are pursuing is a pre-combustion project. The costs vary from between £1,300 per kilowatt to anything up to £2,000 per kilowatt. That is the range of uncertainty that we are working within at the moment. The other uncertainty is future carbon prices. Clearly we have clarity around phase two of the Emissions Trading Scheme but for a carbon capture project that is going to be ready by 2013 that is not really relevant; it is really phase three and beyond that we need to have more certainty on. In terms of where we are on the financials, because of the uncertainty that is created around the carbon price and the capital expenditure, if one looks, say, at the higher end of the capital expenditure range, then to make a project economic, there needs to be some longer-term support. Whether that is from Government, whether it is from an additional piece of legislation, we are not being definitive on. With the current Emissions Trading Scheme and the uncertainty around the future carbon price, no commercial entity would build a clean coal project today.

  Q87  Martin Horwood: Could that long-term support simply come from a sufficiently high price of carbon? Do you need anything more complicated?

  Mr Sambhi: If one had certainty around what range of carbon prices one might expect in phase three. The issue at the moment, because we do not know whether we are going to have 100% auctioning, which is something that we as a company lobby hard for because we do not know how tight any caps that would be imposed might be, is that the range of carbon prices could be anything from as low as €10 to as high as "pick your number" but consultants quote a range of €10 to €100 as the range of uncertainty on future carbon price.

  Q88  Mark Lazarowicz: As a matter of interest, where would you say worldwide is the best example of carbon capture and storage actually in operation at the moment?

  Dr Chapman: The fact is that there are no examples of carbon capture and storage on power plants. There are two examples of carbon capture and storage that are taking the CO2 which happens to be associated with natural gas, one is in Salah in Algeria, a BP project and Sleipner in the North Sea, which is a Statoil project. Both of those projects capture and store about a million tonnes a year. The fact is that that CO2 would have to be separated from the natural gas anyway, so the biggest cost of CCS has been undertaken by the companies before storage They are quite cheap in a sense; they save a million tonnes each a year of CO2 very cheaply indeed. It is the lowest-hanging fruit of carbon capture and storage and it is good because it demonstrates things like security of storage and so on and allows people to develop techniques for monitoring storage. The other one is the Weyburn project which takes CO2 from a coal gasification plant in North Dakota and interestingly shifts it across the Canadian border a distance of about 300 miles to Saskatchewan where it is used for enhanced oil recovery. I wanted to come back, if possible, on the EU Emissions Trading Scheme because it is very important. I completely agree about what has been said about the EU Emissions Trading Scheme, that it does not have the robustness into the future to be bankable. That is not the only reason why projects need support. They also need support because of the first mover, the early mover risk; they also need support because there is a large amount of infrastructure costs associated with the first projects that come on stream. I am sure we will get back to infrastructure. I would like to point out that the Government will raise at least €2 billion from auctioning allowances in the second phase of the EUETS, that is in the five years from 2008 to 2012. In the third phase there is likely to be more auctioning and, as was pointed out, we do not know how much auctioning there will be or what the price will be. The Government could be raising something between €2 and €20 billion euros per annum from auctioning after 2013. By the time you get to about 2014 or 2015, when this project is coming into play, the Government could have a war chest of money to spend on CCS. Basically, in order to finance these projects you need a way of collecting revenue and then a way of disbursing revenue. The Renewable Obligation, quite neatly, collects revenue from electricity consumers and disburses it amongst the projects that it supports. We have a way of collecting revenue because, let us face it, the cost of these allowances bought at auction, will be passed through to the electricity consumer and the electricity consumer will be assuming, if they know the difference, that this is going to some environmental good. If it just goes into the coffers of the Treasury, it probably is not going to any environmental good. If it is recycled to support projects of this kind, then it will certainly be doing environmental good.

  Chairman: That certainly is an issue which the Committee has addressed and sympathises with your view on very much.

  Q89  Mr Stuart: Taking you back, you said £1,300 to £2,000 per kilowatt as a cost. What price of carbon would you require assuming the upper end of those costs?

  Mr Sambhi: Again, there are other variables around: what you assume the overall outright power price is going to be and a number of other factors. To give you an idea of range, we are looking at something, if it is at the higher range—and I have put some caution around that because it is the high end estimate—that would be north of €50 but at the lower end it could be as low as €25. The range is still quite wide. What I am trying to impress on the Committee is still the range of uncertainty around what it costs to build economically a clean coal project. The dilemma that we have, whilst we live with this cost uncertainty now, unless we commit to an accelerated build of clean coal projects, is that we put at risk the achievement of overall emission reduction goals. As I said, once you have exhausted all the low-hanging fruits, you very quickly come to invest in clean coal as an imperative to meet the emissions reduction targets.

  Q90  Mr Stuart: Just to take you back to the question of using the money, if there were 100% auctioning, the principle of the system is of course by 100% auctioning, depending on the cap, that will dictate a price that would bring forward things like CCS, if it is essential, while the Government do just bank the cash. Is that not true? Is it not perfectly possible for the Government to spend none of that money on environmental good but still lead to investment in CCS because of the cap it has imposed and the need to deliver within the allowances allowed?

  Dr Chapman: We all believe that in the long run the EU Emissions Trading Scheme and trading schemes in general will be the mechanism that will stimulate investment in low-carbon technologies, whether it is CCS or anything else. In the meantime we have to put something in place such as the Renewable Obligation that kick starts certain technologies. However, we have to go quite a long way out before we can ever think that there will be bankable certainty on the forward price of EU allowances.

  Mr Steele: We estimate that you need about €65 per tonne of carbon dioxide to make carbon capture and storage economic with the technology as it is at the moment. That number can come down, if we make the technology work better. Right now we have visibility out to 2012 of a carbon price somewhere between €20 and €30 and no idea what it will be beyond that. You are talking about an investment which is going to have to pay back over 20 years. That is the problem, that there is simply not the visibility and solidity of a carbon price to make any of these investments stand up and there will need to be a bridge between the demonstration project that the Government had led the world in coming forward with and a situation where emissions trading will itself drive carbon capture and storage. That may well be happening past 2020, but it is that bridge that we need otherwise it is just not going to happen on the scale.

  Q91  Mr Stuart: The point really is that the Government are going to see a major return from auctioning in the future and should invest a bit more now to help make CCS a reality.

  Dr Chapman: Yes.

  Q92  Mr Stuart: May I take you to the potential global market? What is the potential size of the global market for CCS industries? How do you see it developing over the next few decades?

  Dr Chapman: It really is a very big open-ended question. Whichever way you look at it, the size of marketing CCS will be measured in trillions of pounds, dollars or whatever currency you choose, but it is that kind of order of magnitude. It has to be for it to have the kind of effect that you need it to have on climate change. The IEA have estimated that by 2030 we need 630 power plants equipped with CCS. You have just heard that the price of those power plants could be between £1,300 and £2,000. What are we talking about there? That is probably £2 trillion—thinking on the hoof here—and that is huge money. Of course if the UK gets first into this technology, it gets itself established with a slice of the action. The UK was very good in coming forward with policy on emissions trading and as a result of the UK being a leader in emissions trading policy, London has become the centre of the world's emissions trading. We have the opportunity to do this with CCS and we should step up to the plate.

  Q93  Joan Walley: Can I ask you about the possibility of London being the capital of CCS and what the implications are for manufacturing?

  Dr Chapman: We are not very good at manufacturing in the UK. We have lost a lot of our metal-bashing capability. I have to say that CCS, unlike conventional power plants, involves a great deal more process engineering and, as it happens, we are still good at process engineering in the UK.

  Q94  Joan Walley: Where are the clusters for that?

  Dr Chapman: There are several process engineering companies in the South East and in the North East. You are really talking about more soft skills than before. Typically, a quarter of the total cost of a power plant would be in things like services, soft skills and of course the added value in that area is very much higher. We should not worry too much about the fact that we have lost a lot of metal-bashing capability because the thing that makes money out of power plants is the project management, project financing, investment, all sorts of investment and investment matters, city services, environmental consultancy, engineering design, in this case I mentioned process-engineering, all of these things will be there in spadefuls in carbon capture and storage plants and some metal bashing as well. However, we will have to face that, for example, the likelihood that the equipment that's supplied for the demonstrator will probably be supplied from Japan, America or maybe Germany, but more than likely, not supplied from the UK.

  Q95  Mr Stuart: I would like to come back to the global position. In terms of getting India and China to retrofit all their coal-fired power stations and indeed to fit to all new ones at some point, what is your vision for making that happen in policy terms and technological developments? What is it going to take, because if we do not get China and India doing it, then we are wasting our time from an emissions point of view, are we not?

  Mr Steele: That is why it is so important that we get to grips with the post-combustion technologies, because China and India are installing pulverised-coal-fired plants, which is a completely understandable decision because engineering-wise that is the obvious way to build the power station and those can only really be retrofitted using the post-combustion technology. From that point of view we are very supportive of the Government's decision to focus the demonstration project on post-combustion because that will—

  Q96  Mr Stuart: Is that true of everybody on the panel?

  Dr Chapman: I would certainly agree with that and I would add that even more important than demonstrating the technology is demonstrating political will. We cannot expect China to move without first of all demonstrating the political will.

  Q97  Mr Stuart: I just meant on the post-combustion thing particularly. Are you all happy with the Government supporting post-combustion in the competition?

  Mr Sambhi: Essentially we understand the arguments that have been put forward as to why post-combustion was selected as the exclusive technology. However, going back to the comments that were made at the beginning, clean coal must have a role to play in meeting overall emissions reduction targets. That means pre- and post-combustion technologies have a role to play. We see that when one compares post- and pre-combustion, both have a range of uncertainties around capital expenditure. Post-combustion is slightly less efficient than pre-combustion. The thing that led us down to selecting pre-combustion as the preferred technology was that pre-combustion has been demonstrated to work at scale. That has not yet been done on post-combustion. In terms of the technology for scrubbing flue gas from an existing coal plant or conventional coal plant that has still very much only been proven on a small scale. If it can be proven that that can work at scale, then we can understand why you prefer post-combustion, but where we are sitting today pre-combustion is the technology which has been proven at scale. We do not understand why you would exclude it.

  Q98  Mr Stuart: We are going to come to this later but I just wanted a quick nod from you two and I apologise for interrupting you.

  Mr Steele: I was basically making the point that in order to roll out capture and storage in China and places like that, it will be important to have post-combustion properly tested and assessed. We are hopeful that significant progress will be made in addressing the efficiency penalty that Centrica have mentioned. There is a chilled ammonia process for post-combustion capture that is making an appearance which has less than half the efficiency penalty of the amine process that is currently being used, so that is a very exciting development. I will just mention that, on the pre-combustion route, our parent company, IBERDROLA, actually is a participant in a large-scale IGCC plant in Spain called Puertollano. It has not performed very well and that is one of the factors that have actually driven us towards the post-combustion angle.

  Q99  Dr Turner: I understand that a little while ago there were ten CCS projects in the wings at various stages of development waiting to go, especially including BP's Peterhead project which is now being pulled. Were you truly happy that the government competition was limited to one post-combustion plant? Do you think we would have benefited from a broader spread of projects going ahead?

  Dr Chapman: We are very happy that the Government are doing something, but I have to say it is not enough and it is not soon enough either because the timescale is slipping and that is important because every year that goes by we emit more CO2 and that stays in the atmosphere and builds up the concentration. In short, I guess the answer is no, we are not happy. What we would like to see is a programme which rolls out whatever technology industry is prepared to put its money behind and to take the risk on. There are projects that would have delivered sooner than this demonstration project in a competitive environment if an appropriate fiscal instrument for initiative had been put in place; there are projects that would deliver even sooner than this demonstration and they might well be a pre-combustion technology, but if it were a competitive environment, that would naturally select one or the other.
