Select Committee on Environmental Audit Minutes of Evidence


Examination of Witnesses (Questions 280-294)

DR KEITH MACLEAN

2 NOVEMBER 2005

  Q280 Chairman: Can we talk about carbon capture and storage a bit more? You say in your memorandum that you are engaged in a couple of projects dealing with this. Can you tell us very briefly a little bit more about those projects?

  Dr MacLean: There is really only one which has moved forward, which is the project in Peterhead which is working together with BP and BP's partners there. There is a fairly unique set of circumstances around Peterhead because of the gas pipelines coming in and the proximity of oil fields and gas fields there too. The basic principle there is to bring natural gas into Peterhead, to split it up through a chemical plant into carbon dioxide and hydrogen. The hydrogen would then be burned through a fairly conventional combined cycle gas turbine and the carbon dioxide would be pumped back out again through the unique pipeline which is there and capable of carrying it and be used for enhanced oil recovery in the Miller field. That is a set of circumstances which do not come together in any other areas in that way. However, it will be interesting, looking at the combination of the chemistry and the combustion. The big issue will be making those work together. Most of the individual processes are already up and running, but getting them to work together like that would be a big challenge. That is the main project we are looking at with that, but there are others which we would explore, looking at alternatives for coal-fired power stations as opposed to gas fired power stations, probably with some form of carbon capture and then storage following on from that.

  Q281 Chairman: The Peterhead project is the one you estimate would cost about £400 million.

  Dr MacLean: That is right.

  Q282 Chairman: Do you envisage any of that money coming from the taxpayer?

  Dr MacLean: All of these early projects will require some sort of support to help them through and there have already been discussions about that. Whether it is ROCs, or something akin to a ROC which can be used as a support mechanism, we are quite open to the options and use measures which are being used elsewhere and can be applied to other technologies rather than specifically for that. Certainly a revenue support mechanism for that is definitely one of the things we would be looking at rather than a big capital grant up front.

  Q283 Chairman: This whole area was envisaged in the White Paper to be a priority area for research. Do you think we have made sufficient progress in the last couple of years?

  Dr MacLean: It is starting now, but if you look at some of the imperatives which EDF were describing earlier on about the current trajectory for the generation gap, however big that is going to be, which is dependent upon the demandside growth as much as anything else, clearly we are getting to a point now where, if we are not able to use the new technologies, we are going to have to find some sort of stopgap measures to bridge us through until they do come through. The time is very, very short now and we really do believe that the majority of the decisions which we need to be making to deal with the 2010 to 2016 issues which there will be with nuclear closure and coal closure have to be taken now. To go back to one of the points from the EDF discussion, what the market is looking for is clarity in areas on which Government can give clarity, not about the general way markets operate. We should like clarity on things like the implementation of the Large Combustion Plant Directive in the UK, which is in the gift of the UK Government. We should like clarity on the UK's approach to the second phase of the European emissions trading scheme. Again, the UK's approach to that and knowing how it will approach that is something which can be done. The other big imponderable at the moment, which would probably stop investment even in combined-cycle gas turbines, is whether or not the exiting nuclear licences will be extended for a five- or a 10-year period, which may be a sensible stopgap measure for the keeping-the-lights-on debate and also for the carbon agenda. We have these two things which often work against each other: reducing the carbon emissions and keeping the lights on. We have to look at the measures and the decisions in that light.

  Q284 Chairman: So you are really waiting on the Government for progress to be made on this broad front.

  Dr MacLean: For clarifying those things which are very much their responsibility to provide. We are happy to make the commitments within the market, the market risks and market uncertainties, to do what is necessary, but that framework, those things which the industry cannot themselves change, have to be clear.

  Q285 Ms Barlow: To carry on with the markets and policy instruments, you say you need stability but also that there is no precedent for involving the generating requirements within the framework of a market-led economy in terms of the scale that is necessary. You seem to be implying that the present market-based policy, particularly the regulatory framework, may be inappropriate or insufficient and that it will not be able to deliver what the Government's aims are. The implication from that is that the lights will not stay on.

  Dr MacLean: It is not difficult to say that if growth in demand carries on as it is just now, if nuclear plants, when they are due to, close and the licences expire, if the Large Combustion Plant Directive, which is outwith the UK Government's gift, imposes the closure of the plants and no other investment decisions are made in the meantime, obviously the consequence of that gap is the lights going out. We know that there are decisions there which need to be made and we are trying to show where Government can give the clarity that the market will need to make those decisions to invest. It is clear that over the last five years there has been no significant investment in conventional generation. The only significant investment the market is making in generation is in the renewables market, driven very much by the ROC mechanism. You could say that is a positive example where the clarity of the policy has driven industry to invest and you can see in the lack of investment elsewhere that that uncertainty has resulted in "wait and see".

  Q286 Ms Barlow: How far would you put the blame on the existing regulatory framework in terms of long-term policy and how much change would you want to see in that?

  Dr MacLean: There is a framework at the moment. Think of the first phase of the European emissions trading scheme. It came into force in January of this year: it was not until June of this year that the actual allocations were confirmed. That is an example where you have the entire framework and everything in place and it is something which should work. However, if Government do not tell us what the answer is or what the rules are within that existing framework, then it is impossible to go forward. All we are asking is that within the existing legislation of the LCPD, of EU ETS phase two, of nuclear licence extensions, to name three big examples, just to say what the outcome is of the Government deliberations on that and we will then get on with the job.

  Q287 Ms Barlow: Are you blaming the actual framework? You say the framework exists. Or is it the implementation? How far would you say this is responsible for the lack of large-scale investment?

  Dr MacLean: It is critical that the lack of information in the areas which are outwith the control of the market is clearly responsible for the lack of investment. There are other things out there which would say it is now a sensible time and has been for investment to happen. The uncertainty is not the fault of the framework; it is simply that the decisions are not being made within that framework.

  Q288 Mr Chaytor: Have we ever had or are we ever likely to have a real market in electricity generation?

  Dr MacLean: There is a very active market in generation.

  Q289 Mr Chaytor: Is there a real market?

  Dr MacLean: We have seen the ups and downs of a market scenario. The first up was the so-called dash for gas when there was a tremendous thrust for investment. There was then a change in policy which brought that to an end and it has not restarted since then. There has been a very active market response to the renewables. The market is more than happy to put the money in place for that to be delivered. I certainly believe the market is capable of providing the capital investment, of managing the projects to deliver, operating them to continue to provide the service and looking after all of the risks associated with that. Yes, I do believe that the market is capable of doing that.

  Q290 Mr Chaytor: Do you share the view of EDF that diversity and the operation of the market will take care of everything, including all of the risks?

  Dr MacLean: I have probably already answered that in that I said the market will look after the risks it is capable of dealing with.

  Q291 Mr Chaytor: Can you just clarify that? What is the limit?

  Dr MacLean: It goes back. If the market were to invest in gas and there were then the introduction of a punitive carbon tax which then made that economically unviable and drove the companies who had made that investment out of business, that is the sort of change which the market is not capable of managing itself. It is something which has been a significant change of the rules. It is difficult. Anything involving investment over a 30- or 40-year lifetime, if the aim is to have a low cost of doing that, has to be in an area where the risks are manageable. We are not risk averse; we just want to be able to manage the risks and then the premium which is attached to that in terms of cost will be low. If you put very high uncertainties, then the investment will only be made if the returns are appropriately that much higher. All we are saying is that it needs to be derisked at the moment around things which the Government are perfectly capable of and often say they would like to give us the answer on, but have not as yet.

  Q292 Mr Chaytor: To be more specific, if the market were to invest in nuclear, do you think the risks attached to that should include decommissioning and waste disposal?

  Dr MacLean: It has to be clear who is carrying that risk before investment would be made. The market would be capable of dealing with it at appropriate premiums. That is the issue for risks associated with that sort of thing. If the Government believe they are better able to manage that risk at a lower cost, then that may be the appropriate way of approaching it.

  Q293 Mr Chaytor: How do you view the argument about the crowding out, that at the end of the day the Government are going to have to intervene to some degree and if they intervene to support one technology, it is actually going to deliver a diversity of supply because the Government support for that one technology will dominate everything?

  Dr MacLean: We certainly have a concern about the support mechanism which is targeted at any one specific technology. We, like EDF, do not believe that there is a silver bullet technology. We believe that diversity does help manage the risks, certainly in the longer term. We would look at support mechanisms like revenue support mechanisms which are based on something which is technology neutral. The two key things we are looking at are security of supply and the carbon agenda, so something which is targeted at one or other or both of those which rewards success in achieving those two criteria would obviously be something which does not pick a winner and could be applied to any of the technologies which are delivering on those two counts.

  Q294 Mr Chaytor: Your answers earlier were much more positive about demand management than those of EDF. In terms of demand management, do you think you have the parameters of the debate right? The title of our inquiry is nuclear versus renewables. Do you think it would be more accurate to identify the issue as centralised generation versus decentralised generation?

  Dr MacLean: Decentralised generation has a role to play in the overall mix. The more decentralised you become, the smaller you become, the less efficient it becomes. It can actually have an adverse effect. The great security of supply which we now enjoy has been achieved by joining everything up and having quite a lot of central generation in the mix. We are certainly very keen that we get a degree of distributed generation, a degree of micro-generation. We believe that micro-generation in particular can play an important role in reducing the draw of energy from the grid and therefore how much needs to be centrally generated: more actually seeing it as a demand reduction measure rather than as a competitor to something which is supplying into the grid. We are confident in that; we have made a number of investments ourselves and are pushing that very hard at the moment.

  Chairman: Thank you very much indeed; you have been most helpful. We are very grateful to you and thank you for your patience as well.
