Select Committee on Environmental Audit Minutes of Evidence


Memorandum submitted by ScottishPower Limited

  1.  ScottishPower is one of the UK's six large integrated energy suppliers, and is owned by IBERDROLA, one of the world's leading utility groups and a particular leader in low carbon generation. Our sister company, ScottishPower Renewable Energy Limited, is the UK's largest wind power generator. We have electricity networks in South and Central Scotland, Merseyside and North Wales and some 5.2 million energy customer accounts. Our power generation assets include the Longannet and Cockenzie coal plants in Scotland and a number of gas fired stations in England.

  2.  This Memorandum relates to the Government's announcement on the competition to design and build a pilot Carbon Capture and Storage (CCS) project and policy towards funding and developing CCS more generally. ScottishPower is developing a potential entry in the competition, based on its coal fired power stations in Scotland and offshore carbon dioxide (CO2) storage locations.

THE CCS COMPETITION

  3.  In our view, the Government's announcement was well judged, both as to the process for the competition and as to substance.

Process of the competition

  4.  We believe that it has been very helpful for the Government to clarify what kind of project it is looking for at this stage. Prior to the announcement of 9 October, it was difficult to get partners to focus on specific propositions because there was doubt as to the approach most likely to be followed. We think that to have left the key technological issues open longer would have made the competition very difficult to manage, given the significant issues of timescale, regulation and risk allocation that will need to be addressed.

  5.  Going forward to the competition itself, we are encouraged by the Government's approach of being clear about what it is seeking. It would be helpful, at quite an early stage, for this to include guidance on the Government's requirements, critical success factors and selection criteria, so that project entrants can begin to develop the correct technical offer. We will be reading the Information Memorandum of 19 November 2007 with this in mind.

  6.  An important element of this will be the Government's attitude to risk allocation, as there is a clear interaction between the amount of risk outwith the bidder's control that the project is required to bear, and the level of the bid.

Substance of the announcement of 9 October

  7.  We agree with the Government's approach of concentrating support such that up to 100% of the costs of a project can be covered. This should ensure that a project does indeed go ahead; we had previously been concerned that support might be spread too thin, making it unviable for industry to proceed. While we would obviously have liked such a level of support to be offered to more than one project, we understand that there have to be constraints on spending.

  8.  We envisage that the funding would best be provided in two forms. The first would be an initial capital payment in respect of the investment needed to install the CCS facilities. The second element would be in respect of the CCS operating costs. As well as direct funding, this could possibly involve some sort of minimum CO2 price and the ability to trade out the saved CO2 permits on the EU ETS.

  9.  As to the actual choice of technology, we believe that the Government was right to focus on post-combustion coal. Given the abundance of coal, its high level of CO2 emissions and its increasing use for power generation in many parts of the world, it is clearly right to focus the capture and storage demonstration on that fuel. We also think that post combustion makes the most sense:

    —  the technology of choice for new coal fired power generation in most parts of the world is undoubtedly advanced supercritical boilers using pulverised fuel. Demonstrating and deploying post-combustion capture (which is the method appropriate to this technology) is going to be crucial in controlling emissions worldwide;

    —  there are significant retrofit opportunities in Great Britain for post combustion capture, either on existing plant or on new coal build, likely to be capture ready advanced supercritical;

    —  our international experience, through our parent Iberdrola, suggests that as a cost effective, reliable and flexible generation plant, IGCC is not yet there. This is evidenced by the fact that IGCC is not being favoured at present for commercial generation projects in most parts of the world. A demonstration based on that technology might not therefore fit with actual plant deployment plans. Furthermore, we suspect that there would be so many issues concerning the actual IGCC plant, that it would be difficult to focus the demonstration project on the capture and storage element rather than the power station to which it was attached; and

    —  use of post-combustion technology gives the option of undertaking initial testing using flue gases from existing subcritical boilers, so providing for a more flexible implementation plan with fewer major dependencies on other activities.

  10.  We are also supportive of the Government's approach of seeking to demonstrate the entire storage chain and the use of an offshore CO2 store.

POLICY TOWARDS FUNDING AND DEVELOPING MORE GENERALLY

  11.  Looking to the future, we think that the most obvious signal to support the long term deployment of CCS will be the price of carbon. Although it may well be sensible to have a significant element of free allocations in the third phase of EU ETS as a transitional measure, a move to auctions will be appropriate as 2020 approaches. If free allocations do continue beyond phase 3, it will be important that CCS plants gain allocations no lower than coal plants of the same output without CCS. This is a matter which should be taken forward at EU level in the third phase of ETS.

  12.  Some thought will need to be given to the price of carbon. There is still very limited visibility of this going forward. If this remains a problem, the Government will need to consider whether there are any domestic measures that could be taken to give some more assurance to industry that investments made off the back of the carbon price will not be stranded.

  13.  A key challenge in the use of post combustion carbon capture is the efficiency penalty from the amount of energy needed to operate the capture system. We believe that this will be an important area to seek improvement as it would significantly improve the economics of a CCS plant. Accordingly, the Government should continue to support technical innovation to address the issue of energy cost/efficiency penalty as well as wider questions such as CO2 storage identification and verification. These can be addressed through ongoing activities such as the Technology Programme and the Hydrogen and Fuel Cell and Carbon Abatement Technologies (HFCCAT) Programme.

  14.  Consideration might also need to be given to an intermediate mechanism to maintain the momentum of CCS deployment and bridge the gap between the current competition and a world where the carbon price will drive forward CCS investments. This could be something modelled broadly on the Renewables Obligation, but separate from it. Whether such a mechanism will be required will depend on how soon, and how strongly, the carbon market matures.

  15.  We have also considered the option of regulatory models to encourage the use of carbon capture and storage. We think that the option of requiring new fossil plants to be "capture ready" is reasonable, providing there is an adequate definition of what capture ready means and that meeting that definition is not disproportionately expensive. It will be important that this requirement, if introduced, does not stand in the way of the construction of adequate capacity by around 2015 to meet Great Britain's power requirements.

  16.  We would advise against going further and making retro-fit of CCS a requirement, either on "capture ready" or other plants. In the long run, if the price of carbon does not justify fitting CCS, then regulating to force it would be a misallocation of resources. Moreover, the possibility of compulsory CCS could be detrimental to investment prospects for new coal plant, especially supercritical coal, despite the fact that this technology has significantly lower emissions than existing coal plants. This could have unintended effects and could impact negatively on supply security. Making CCS mandatory for new plant should only be considered if it can be shown to be technologically and commercially viable for the developer.

  17.  A financial framework that will make CCS viable is one key element of what is required to see the technology flourish. The other element is a satisfactory regulatory system to address the CO2 storage process. It will be important that prospective CCS project developers (whether or not successful in the competition) have an opportunity to engage in dialogue with Government on the high level licensing principles. Such dialogue will help ensure that the regulatory regime is effective and that projects can be prepared for development against a known and realistic framework.

  18.  The framework for approval of CCS projects will need to be carefully designed, to ensure that all relevant issues (including environmental issues) are properly considered, whilst avoiding the delays that have so strongly hampered the development of wind power in Britain. It will be helpful if the number of separate approval bodies is minimised and that the UK and devolved authorities work together to formulate a uniform and supportive approach.

Conclusion

  19.  A significant role for fossil fuels remains essential in the UK electricity generating sector, not least to cover the variation in output from renewable generators. CCS is a technology which can play a vital role in minimising the emissions of CO2 from the fossil component of the power sector. However, there is a great deal of work still to do on both the economic and regulatory frameworks needed for it to succeed. We will need to press on purposefully if significant deployment is to begin around 2020. That said, the Government's approach of seeking a demonstration starting in 2012-14 and moving on to a wider deployment seems right and best calculated to secure a positive result.
