Select Committee on Science and Technology Minutes of Evidence


Examination of Witnesses (Questions 1 - 19)

WEDNESDAY 16 NOVEMBER 2005

MR BRIAN MORRIS, DR GEORGE MARSH, DR JIM PENMAN AND MS HELEN FLEMING

  Q1  Chairman: May I welcome our expert witnesses to the first session of our inquiry on carbon capture and storage and the many people who have come from the Royal Society who are part of the pairing scheme with MPs. You are particularly welcome to what will be one of the most exciting sessions you will ever, ever witness! I would like to ask a general question just to start us off. I think it is now accepted that the UK will miss its 2020 target for a 20% reduction of CO2. Is this because the Department and its advisers, particularly in Defra, DTI and the Treasury, have put too much faith in carbon capture and storage as a solution to this problem?

  Dr Penman: No, I do not think it is because people have put too much faith in carbon capture and storage. I think it is still an open question whether we shall miss our target.[1] The current Climate Change Programme Review is assessing what additional action we need to take. I think it is certainly accepted we need to take additional action to get back on track towards the target. The current Climate Change Programme does not contain any action on carbon capture and storage because this technology had not been very widely thought about at the time we were writing it. It certainly is not true that we put too much faith in it.


  Q2  Chairman: Do you agree with that?

  Mr Morris: I do. It has only been in the last two or three years that carbon capture and storage has had an increased profile. I certainly would agree that it has not really been recognised as a possible technology until very recently and I do not think it has featured in any mechanisms or any policies which have tried to look at the targets for 2020. I would even go as far as to say that one would tend to think about this technology as being beyond 2020 and, as I think you will see in the Carbon Abatement Technology strategy, we think of this technology as being something beyond that time. It is not really a technology that could apply up to 2020.

  Q3  Chairman: Helen, the Treasury has shown absolutely no interest in putting funds into this technology on a large scale. Does that mean that you have abandoned the target for 2020?

  Ms Fleming: No, not at all. Did you say the target for 2020?

  Q4  Chairman: Yes. Is the 20% reduction by 2020 now dead?

  Ms Fleming: By 2010, I think, Chairman.

  Q5  Chairman: No. You have a 2010 target and you have a 2020 target. The 2010 target is a Government target.

  Ms Fleming: We are working, as Jim said, through the current Climate Change Programme Review to look at all the options for how we will meet those targets and a lot of work has gone in to assessing all of the options for that. In respect of carbon capture, as Brian said, this is a technology that has come to the fore relatively recently. The Chancellor has said in his Budget earlier this year that he was interested in exploring the scope for using economic incentives to promote the use of carbon capture and that is something that we have been working on.

  Q6  Chairman: Do you feel that this new technology, which is a sort of a saviour, means that people have put a great deal of faith in saying that we are there to capture carbon from coal and gas fired production of electricity and therefore the nuclear option will go out the window? Is that why it is so strongly on the political agenda now?

  Dr Marsh: My view is that it has been recognised now as another big technology that could make a significant contribution to CO2 abatement. It addresses the large emissions that come from the electricity supply sector and its costs, as far as we know them, because there is a lot of uncertainty at predicting costs 10 or 20 years into the future, are comparable with nuclear and other options.

  Q7  Chairman: In terms of sustainability of supply and security of supply, is that now the number one priority for all of you in terms of advising your respective departments?

  Dr Marsh: It is one of the issues. In addition we have got to think about the UK targets and also the lead that the UK wants to give internationally on CO2 abatement as well. CCS is really relevant to all of those.

  Q8  Chairman: By 2020 we will have something like 90% of gas coming from either Russia or Saudi Arabia to geo-political hotspots. Is that a sensible avenue to be going down?

  Dr Marsh: I think you can achieve diversity in a number of ways in terms of the choice of fuels or a multitude of sourcing. I guess if we go to gas then the key issue is to have a diversity of sources.

  Q9  Chairman: Are there many other major sources apart from Russia and the Middle East?

  Dr Marsh: There are lots of sources in the Middle East and in North Africa, Algeria and Norway still have lots of reserves as well. I suppose the options are a combination of gas pipeline supply and also liquefied natural gas supply as well.

  Q10  Mr Newmark: To what extent is funding for CCS in competition with funding for renewables in general? Do you agree with those who say that support for CCS encourages dependence on fossil fuels?

  Mr Morris: I think renewables already has a more considerable forward allocation of funding than we have. Our budget at the moment per year is about £6 million and a good bit of that goes into the R&D we have been doing over the last three or four years into clean fossil fuel technologies. So the emphasis of the funding has been more on renewables at the moment. We have also recently announced £25 million for a demonstration project which would run from next year and that is the first time ever we have had some money for demonstration projects. Sorry, I have forgotten your second question.

  Q11  Mr Newmark: Do you agree with those who say that support for CCS encourages dependence on fossil fuels?

  Mr Morris: It allows you to use fossil fuels in a way which does not damage the environment and I think that is the important point about it. It gives you an opportunity for diversity of supply. It means you can possibly start to continue to look at using gas and coal in ways which will not be damaging to the environment. It provides you with the opportunities to continue to use it without damaging the environment.

  Q12  Dr Turner: Can I just pick you up on that point, Mr Morris, because there is quite a lot of enthusiasm out there now for clean coal technology, etcetera. Given that the timelines for carbon capture and storage and its application are rather long and given the amount of fossil fuel generation that is already in the pipeline, do you not think that there is a risk, especially if other developers think clean coal technology or clean gas technology is going to be the answer, we will go for fossil fuel because renewables are not going fast enough, we will actually do more environmental damage because it will be up to 20 years before carbon capture and storage becomes a widespread reality? So we will actually have released many megatonnes of CO2 before carbon capture and storage becomes available, rather more than we might if people had a different policy and mindset and were focusing more on renewables.

  Mr Morris: I agree with you that there is the problem that the technology is not there now and in the meantime you have to look at the shorter-term technologies such as wind power which is obviously there now. I suspect this is a question for the energy review which will be announced in the near future. We are very aware of the issue and very aware of the problems and the timing is awkward to say the least. In the meantime we have countries like China and India which are building huge capacity at the moment. Each year they are putting in coal fired power plants equal to the total capacity of the UK and that is very worrying. What is worrying is the possibility of carbon lock in. That is one reason why in the G8 we were trying to promote the idea of "capture ready" plant, where if you built a new power plant, whether it be coal or gas, you would build in the right sort of hooks so that later on you could attach the carbon capture technologies which would solve the problem in the future. I agree with your point, the timing is awkward. In the meantime if we are going to use these technologies and we are going to accept that fossil is going to be in the energy mix for many decades to come we have got to prepare for that now. We have got to be doing the work today to enable those technologies to be there by 2020 to handle that problem.

  Dr Penman: The thing to bear in mind is that fossil fuels are going to be used in future probably whatever happens. This is not a zero-sum game and this is a classic transition technology. I think we are looking in the long term to low carbon technologies and CCS helps us work, starting with the existing energy system as it is to achieve that. If we did not do that we would run the risk of incurring higher costs than we would otherwise have done.

  Q13  Dr Turner: I do not disagree. Do you not see the risk of actually encouraging a greater dependence on fossil fuel use than we might otherwise seek and thereby greater environmental damage even if the new plant is "capture ready" because it will be 2020 before capture is likely to be fitted?

  Dr Penman: I see the risk as higher if we do not go along that path.

  Q14  Dr Turner: I am not suggesting we do not go there, but there has to be an important policy caveat. Do you not agree?

  Dr Penman: I think one has to think about these things. One also has to bear in mind, for example, the political power that is behind fossil fuels and how we engage that to achieve this transition. It is issues like that we also need to bear in mind.

  Dr Marsh: I have heard a number of comments about how this is a long-term technology. Let us be clear, Brian is right, the constraints of the build time preclude a significant contribution to the 2010 target, but most of the technology that we are talking about is available and deployed. The new thing that needs to be done is to combine it in an integrated process for carbon capture and storage and certainly quite significant quantities of technology could be deployed by 2020 or possibly sooner than that.

  Q15  Chairman: You mentioned the issue of India and China and the speed at which they are bringing new coal plants on. China is not going to say, with 200 years of coal, "We're suddenly going to spend all this money on putting in this technology when America and Europe and the rest of the first world have been using it for 150 or 200 years." How are we going, as part of our strategy, to encourage China to put in carbon capture facilities either with their plant or indeed to put retrofit facilities in in order to do it later? Should we be involved in that? Should we be helping to fund that, Helen?

  Mr Morris: Let me start. We are very actively engaged with China. The G8 conference in Gleneagles invited developing countries along and China was among them. The Chinese are aware of the problems around increased levels of carbon dioxide in the atmosphere and the issues around climate change and the impact it could have on them. Only yesterday we signed our bilateral agreement with China into research and development into clean technologies. Lord Sainsbury and the Minister of Science and Technology from China signed this agreement yesterday afternoon. That is setting a basis for us to work with them in areas of research and development. On top of that, arising from the British Presidency of the EU, there has also been an EU-China agreement signed this week to look into carbon capture and storage in China. The first phase is that the UK Government has put in £3.5 million and £3 million of that is from Defra and £500,000 the DTI. That is going to look at the feasibility of carbon capture and storage projects in China. Phase two would be a design and phase three would be a build. Obviously the costs increase considerably as you go along and there would be need for thought given as to how that is going to be funded, but at the moment we are looking at the feasibility of doing that. I think it is important to emphasise that the Chinese, more so than countries like India and America, are very aware of the consequences of climate change and are very aware that they want greater capacity for their economic growth but at the same time they realise the damage that burning coal without trying to control the emissions is going to do not just to the planet but to their own prospects in the future. They are very aware of the issues. We are certainly having lots of discussions with them about this and we are hoping to come to a good collaborative arrangement with the Chinese over time.

  Q16  Chairman: Helen, do you feel we need to part-fund those developments together with probably the Americans if they can be persuaded?

  Ms Fleming: I think the Treasury clearly agrees, as the rest of the Government does, that this is a global problem and certainly the issue about industrialisation in the developing world, particularly China, is one where we need to encourage them to go down the route of looking at all the carbon abatement options and we are certainly working closely with colleagues to make sure that the right processes are in place for that. As to whether it will require additional funding by Government, we will have to see and we will have to consider that at the right time. Clearly the initial work to set out the feasibility of the projects needs to be done first and clearly any decisions on funding would be a matter for ministers once that was done.

  Q17  Dr Harris: Do you see any risks with this technology both in terms of actual risks—environmental and other—and in terms of public acceptance? Obviously the two are linked.

  Mr Morris: We are very aware of the perception of the risks, the risks basically being if we are storing carbon dioxide beneath the ground, particularly as we are thinking of it in the depleted oil and gas fields in the North Sea, then there is the concern that the carbon will leak out again. You are seeing experts from the British Geological Survey later on and I think they will be able to give you much more advice on those issues that I can. Where it has been done to date, such as in the Sleipner field in the Norwegian part of the North Sea, the carbon dioxide they have been storing, which is about a million tonnes a year, has not leaked out, it seems to be staying in and behaving itself! The risks do seem to be manageable based on what has happened so far around the world. What is interesting is that there is a considerable store of natural CO2 beneath the surface which seems to have been sitting there for millions of years and it has not come out yet. One of the ways around ensuring that those risks are minimised is through verification. There is going to be an issue there about making sure that it is controlled. We are aware of the public perception issue. The Tyndale Centre was doing work on that and we contributed to the funding of that work to try and understand how people saw this technology. One of the activities arising from the Carbon Abatement Technology strategy is that we intend to develop a communications strategy which would try to raise the issue with people and try to tell them objectively what it is about, what the risks are and what the benefits are. We are aware of that issue. We know it is going to be a difficult issue as well.

  Q18  Dr Harris: Why do you think it will be a difficult issue?

  Mr Morris: When people think about storing carbon back under the ground there must be some concern about it leaking out again and whether we are not really just putting off the problem for the next generations. I think it is a very understandable problem. We need to be able to demonstrate that we are doing that in a responsible way for the future.

  Dr Penman: A couple of years ago the DTI commissioned a very interesting study on risk from consultants which I think is in the public domain. I think the conclusions were that there were risks associated with what you might call the engineered infrastructure, the pipes and all that sort of thing, but they were within the normal range of risks which society faces and are managed in accordance with normal procedures. The Intergovernmental Panel on Climate Change has recently published a special report on carbon capture and storage which broadly confirms that judgment. As Brian says, it indicates that the risk from geological storage, if properly done, is not large. Clearly we have to continue to think about the problem and justice must not only be done, it must be seen to be done.

  Q19  Dr Harris: We have had evidence which says, "Migration of CO2 into aquifers used for potable water supplies could lead to acidification of those resources, or their contamination by destabilisation of heavy metals naturally sorbed or precipitated on aquifer minerals such as iron oxyhydroxides . . ." To the public, particularly if provoked by interested parties, that is "acid in the drinking water". Something "terrible" like iron oxyhydroxides might even be worse than GM, it might be GM for all the public know and the sand contamination is in there as well. Have you thought about how you are going to deal with this, particularly given the fact that there may be pressure groups saying, "This technology is just allowing people to burn coal so we're going to go for them on this"?

  Mr Morris: Not every aquifer is going to be the right aquifer for storing CO2. When our colleagues from the British Geological Survey give evidence later on I think they will be able to answer your question far more competently than I can.
