Select Committee on Environmental Audit Written Evidence


Memorandum submitted by Scottish and Southern Energy

  Scottish and Southern Energy plc (SSE) welcomes the opportunity to respond to the Environmental Audit Committee's inquiry into the Pre-Budget Report, and in particular to the request for views on the Carbon Capture and Storage (CCS) demonstrator competition, and also general policy with regard to funding and developing CCS.

  SSE is one of the largest energy companies in the UK and has been involved in CCS activities for many years, through the Peterhead project with BP and a variety of other activities. Although the Peterhead project was based upon pre-combustion technology, ruled out by the CCS competition criteria, SSE is also involved in post combustion activities, and is not wedded to either technology. Against this background, SSE believes the CCS technologies are not sufficiently mature to choose a winner today, and both require demonstration in the near to medium term. Longer term, SSE believes the market will decide which is the most appropriate CCS technology, and it is likely that both will have a role.

  The key criteria of the CCS competition as published, are that it should be a post combustion technology applied to coal; it must demonstrate a working end to end chain of capture, transportation and storage by 2014; a staged approach may be appropriate and can be taken where 50-100MW are demonstrated by 2014 (with transportation and storage), and between 300-400 MW size as soon as possible thereafter.

  The rationale given for the criteria was the international relevance of post combustion technology for rapidly industrialising countries such as China and India, and ongoing international activities in relation to pre-combustion and natural gas fired post combustion capture technologies in the US and Norway respectively. SSE believes the implication of this decision will be to delay the implementation of a meaningfully sized CCS demonstration in the UK. This and other issues arising from the CCS competition criteria are discussed below.

  Prior to the announcement of the criteria for the competition, a large number of pre-combustion projects were under development, reflecting the increased maturity of the technology. Any of these projects would ensure the storage of a significant volume of CO2 (2+ Mtes/year); support the installation of a meaningful transportation and storage infrastructure; and be available in the 2012-14 timescale. These benefits are now at risk due to the narrowing of the competition to just one technology.

  The competition criterion recognises that a phased approach may be required, and states that this is acceptable providing 50-100 MW of CCS is installed by 2014. Given the CCS activity worldwide, it is highly unlikely that the UK will be teaching the world anything new in 2014 with 50-100 MW of CCS.

  SSE is sceptical that the competition as announced will succeed in having any great impact on the technology choices made in China. We question, given that UK faces its own energy challenges, whether it would not be more sensible to use this competition to focus on meeting our own challenging energy needs at home—assisting China more directly through the CDM mechanism or other international funding vehicle. In the meantime the UK has its own challenging emissions reduction targets and a desire to maintain fuel diversity. With the right support CCS could play an important role in this over the next 10-15 years.

  The phased approach is potentially inconsistent with the requirement for demonstration of the end to end chain by 2014. Early start on a phased approach will involve the use of a sub-critical plant. The quantity of CO2 capture, the location of the plant, and the short term nature of a phased technology development step, means that investment in transport and storage may not be justifiable. SSE believes that long term post combustion capture CCS operation should be with supercritical plant, but none exist today. If the phased technology development is delayed until a new supercritical plant is available, will the CO2 quantity and the short term nature of the phased technology development step justify the investment in transportation and storage infrastructure, to achieve the 2014 ambition?

  In conclusion, if a phased approach is required, and it is delayed until supercritical plant is available, SSE see a real risk that the larger scale 300 MW demonstration may not be operational until nearer the 2020 timescale.

  Whilst there were a number of serious pre-combustion projects under development, SSE doubt if there are many post combustion projects under serious consideration which would match the criteria.

  Whilst SSE can appreciates the desire to develop a technology of international relevance, it will most likely result in smaller volumes of CO2 captured and stored in the medium term, and delay the development of transportation and storage infrastructure. If this likely outcome is not acceptable, then the wrong technology choice has been made, and an alternative project based upon pre-combustion technology is required. There has been too much focus on the combustion technology at the expense of ensuring the competition delivers viable long-lasting and re-usable transportation and storage options.

  SSE suggests that if the objective is early end-to-end chain implementation, then pre-combustion is the more appropriate technology.

  SSE welcomes the leadership shown by the UK Government in the field of CCS, but feels the CCS competition as envisaged will not result in the sufficient material progress, with the real danger that the UK will lose the leadership in this area that it has enjoyed to date.

  SSE believes the Government should quickly announce a more comprehensive, cost effective and ambitious approach to demonstrating CCS in the UK. This should be achieved by creating the right policy environment to encourage a collaborative approach—bringing together government, energy companies, engineering specialists and other relevant stakeholders. The new approach should involve a combination of pre-combustion technology to underpin the end-to-end chain infrastructure, alongside a phased development of post combustion technology, connecting into the end-to-end chain infrastructure. SSE believes this is best achieved through the early announcement that the UK intends to support a second demonstration project in the same time period and that this competition will focus on pre-combustion technology and shared used of transportation and storage infrastructure. SSE believes it is essential for the UK to retain its leadership in CCS.

  With to regard to policy for funding and development of CCS more generally, comments made above notwithstanding, SSE welcomes the commitment shown to date by the UK Government in these areas, and supports the continuation of the activity going forward. We believe that a broad policy objective to reduce the UK's carbon intensity coupled with a stable and longer term framework for the EU ETS will be sufficient to support the wider deployment of CCS once both technologies have been demonstrated at scale.

  SSE trusts the Committee will find the views expressed in this letter helpful, and is available for clarification if required.
