Select Committee on Environmental Audit Written Evidence


Memorandum submitted by BP

SUMMARY

  1.  BP is not a part of the nuclear industry, but its potential contribution cannot be ignored. Whenever a potential means of reducing CO2 emissions is rejected, it becomes more difficult to achieve the desired environmental objective.

  2.  BP's biggest contribution to "keeping the lights on" still lies in its core and traditional business of finding and producing oil and gas. The opportunities for increased gas use to reduce CO2 emissions should not be forgotten. The displacement of coal-fired generation by efficient gas-fired generation can reduce CO2 emissions by more than 50%.

  3.  BP believes that renewable forms of power generation can make a substantial contribution to future energy requirements at a reasonable cost and with limited impact on the environment.

  4.  BP's expertise in the renewables sector lies essentially in solar, and to a lesser but growing extent, in wind. For the UK, wind is currently the most favoured option.

  5.  It is also possible to go a substantial step further with power generation from both gas and coal by using CO2 capture and sequestration technology. This can prevent the release of more than 90% of the CO2 resulting from fuel combustion at the power station.

  6.  BP's and partners' Decarbonised Fuels Project (known as DF1) based on the Peterhead Power Plant and the UKCS (United Kingdom Continental Shelf) Miller Field presents an immediate and effective way of establishing the necessary large-scale technology demonstration of CCS. It would produce significant environmental benefits by reducing emissions of CO2 by 1.3 million tons per year, the equivalent of removing 300,000 cars from the roads. Indeed, in terms of the immediate future, this single project would provide around 350MW of clean electricity—enough to provide power for all the homes in a city the size of Glasgow or Manchester.

  7.  Policy makers should realise that any credible policy to reduce CO2 emissions must embrace CCS as part of the portfolio, as recognised by the IPCC special report on CCS; and that this ought to be acknowledged in any fiscal or regulatory regime designed to assist low carbon or carbon free energy to compete with fossil fuels.

INTRODUCTION

  1.  Most are agreed that if the world wishes to guarantee security of energy supplies, and in a way which is consistent with environmental objectives and principles, it cannot afford to forego lightly the potential offered by either nuclear, renewables—or, not mentioned specifically in the subject of this Inquiry but undoubtedly of equal significance, Carbon Capture and Storage (CCS).

  2.  BP is not part of the nuclear industry. But we have always acknowledged its potential contribution. When in November 2003, Lord Browne of Madingley, BP's group Chief Executive, discussed the necessity and challenge of stabilising atmospheric concentrations of greenhouse gases at around 500-550 parts per million, a number of options were identified as a means of reaching this goal. One of these options was an increase in nuclear capacity: 700 1GW nuclear plants, representing a 4% per annum increase in nuclear capacity, would contribute 1 Giga tonnes per annum of avoided emissions of carbon by 2050. To reach the desired atmospheric contributions mentioned above, the world would need to achieve up to 7 Giga tonnes per annum by 2050.

  3.  It is clear that whenever a potential means of reducing CO2 emissions is rejected for whatever reason, it becomes more difficult to achieve the desired environmental objective. So if, for reasons such as cost, waste management, safety or security, the nuclear option is judged unacceptable, other options (such as increased natural gas, much lower speed limits, more renewables etc) would have to contribute even more. It is for policy makers to guide these choices—whether they wish to be neutral, or favour one against another. Industry can only explain the options and associated costs: and then, deliver.

  4.  BP's biggest contribution to "keeping the lights on" still lies in its core and traditional business of finding and producing oil and gas. The importance of this role is highlighted by the concern regarding winter gas supplies in the UK, an issue that BP is helping to address through our North Sea operations and our interest in LNG import terminals. Although there is increasing attention on possible uses of oil and gas in forms which avoid incurring environmental penalties, the opportunities for increased gas use to reduce CO2 emissions should not be forgotten. The displacement of coal-fired generation by efficient gas-fired generation can reduce CO2 emissions by more than 50%.

  5.  It is also possible to go a substantial step further with power generation from both gas and coal by using CO2 capture and sequestration technology. This can prevent the release of more than 90 per cent of the CO2 resulting from fuel combustion at the power station. BP and partners are developing a large-scale generation project with CCS at Peterhead in Scotland (entitled DF1). The potential contributions of CCS and renewables to Britain's energy future are the subject of this memorandum.

THE SCALE OF THE PROBLEM

  6.  The consensus seems to be that electricity demand will continue to grow, but at a slower rate than GDP growth. It is also expected that some existing nuclear and coal-fired generation will shut for either safety or environmental reasons. These factors mean that new power generation will be required. Some would like this to be filled by renewables. However, combining demand projections from sources such as National Grid combined with realistic closure assumptions for existing power stations, indicate that the rate of renewables development—as implied by the Renewables Obligation mechanism—is insufficient to meet demand in the medium term (even if this target of renewables expansion is achieved).

  7.  BP believes that renewable forms of power generation can make a substantial contribution to future energy requirements at a reasonable cost and with limited impact on the environment. This is particularly true for optimally sited wind power, where the costs are converging on those of thermal generation. However, permitted locations for onshore wind are limited, and the problem of intermittency is real and significant. Additionally, both onshore and offshore wind have power transmission issues given their distance from the electricity demand centres.

  8.  The factors limiting the rate of renewables development and the issues associated with intermittency point to a need to develop other options for meeting future energy requirements in a sustainable way. It is also the case that low-carbon generation is needed very soon if the UK is to achieve its 2010 targets. A calculation of the required reduction indicates that it would require the replacement of 135 TWh of coal-fired generation with low carbon electricity.

THE CONTRIBUTION OFFERED BY RENEWABLES

  9.  BP's expertise in the renewables sector lies essentially in solar, and to a lesser but growing extent, in wind. For the UK, with its good wind resource but poor insolation, wind is currently the most favoured option. As noted already, ideal locations for onshore wind are limited, and the public acceptability of onshore wind farms is becoming a limited factor.

  10.  Whatever form is considered, it is a reality, both in the UK and elsewhere, that the expansion of renewable energy capacity is dependent upon the fiscal, regulatory and incentive mechanisms in place. BP believes that there is a need for governments to play an enabling role, including market-based support mechanisms. There is no inherent or principled conflict between assistance for immature technologies and liberalised and competitive energy markets—provided that the assistance doesn't seek to "pick winners" and is relatively neutral as between different options for reducing CO2 emissions.

CARBON CAPTURE AND STORAGE

  11.  Although they offer tremendous scope for growth, the issues confronting renewables suggest that alternative low-carbon solutions are also necessary. The need for large-scale, low-carbon generation options, which can be brought online quickly, is the main driver for BP's development of a hydrogen burning power station at Peterhead in Scotland, with associated carbon capture and sequestration. This DF1 project builds from a range of proven technologies, has costs comparable to other low-carbon technologies deployable in these timescales, and could be replicated to reduce significantly UK CO2 emissions. Indeed, it could be brought online in time to contribute to meeting the UK's 2010 CO2 emissions target. The potential offered by CO2 Capture and Storage (CCS) is increasingly recognised, as evidenced by the recent IPCC Report. CCS needs to be seen as complementary to both energy efficiency and renewable options for power generation.

  12.  The United Kingdom is especially well placed to explore the potential of CCS. The North Sea basin is ideal for large scale storage. As a result of historical policy frameworks, the geology under the North Sea is very well understood and there are sound grounds for confidence that UKCS oil and gas fields are well suited for storing CO2 and allowing Enhanced Oil Recovery (EOR). In addition, the North Sea basin has large deep saline aquifiers which offer the potential of excellent CO2 sites. Indeed, together the oil, gas and saline aquifiers have adequate capacity to store all of the CO2 produced from power generation in Europe for some 50 years. Finally, recycling the North Sea pipeline infrastructure could play an important part in enabling cost effective access to these reservoirs. But much of the existing infrastructure which can be utilised for CCS will be decommissioned over the next 20 years, so the UK's window of opportunity to gain material benefit from CCS technology will close as that infrastructure is removed.

  13.  The inherent advantages of the North Sea in terms of storage and infrastructure not only provides the UK with an opportunity to achieve significant and rapid reductions in CO2 emissions—DF1 alone would reduce them by 1.3 million tons annually, the equivalent of removing 300,000 cars from the roads. But in addition, higher employment and enhanced energy security would be one of the consequences of the widespread deployment of CCS in the North Sea.

THE TECHNOLOGY

  14.  The technology is developing rapidly, and has three elements: Capture; Transportation; and Storage. When integrated, these can be used to generate "green" electricity using CO2-free Hydrogen.

  15.  "Capture technology" is already available, but for the most part it has only been tested at relatively small scale (although DF1 provides the first opportunity of demonstrating the technology in association with a large power plant in operation). In respect of "Transportation", the oil and gas industry has over 30 years experience in transporting large volumes of CO2 in pipelines and ships. And in terms of storage, the oil and gas industry has over one hundred years of experience identifying and managing fluids in the deep sub-surface. [For further details on the technological aspects, we would refer the Committee to BP's submission to the Science and Technology Committee's accompanying and simultaneous Inquiry into CCS.]

THE COSTS

  16.  The costs of power generation using H2 are competitive with those of renewables and nuclear, but not non-decarbonised fossil fuels. Current estimates of the incremental costs of generating power from H2 (as against fossil fuels) are $55-65 per megawatt hour ($/MWh), which is similar to the level of support offered to renewables under the Renewable Obligation Certificate (ROC) scheme. It is expected that technology costs of CCS will reduce over time, and will require diminishing support. If so, the competitiveness of CCS will progressively increase.

  17.  Infrastructure costs for moving CO2 are a significant component. But some of this cost can, as with DF1, be offset if the re-use of existing infrastructure is possible and encouraged. Equally, were the United Kingdom to become a global leader in the export of technology and expertise, this would further help to offset the initial costs of developing CCS technology.

BP'S DF1 PROJECT

  18.  Against this background, it may be helpful to describe a little more fully the DF1 Project, which has three main components:

    —  the generation of "carbon free' electricity" through the conversion of an existing gas-fired power station near Peterhead in Scotland to run on hydrogen;

    —  the manufacture of hydrogen—in order to supply the power station—by reforming North Sea gas and capturing the resulting carbon dioxide;

    —  the transportation of the captured carbon dioxide via an existing offshore pipeline to the Miller oil and gas field in the North Sea—and injecting it into the reservoir to recover additional oil reserves and to extend the productive life of the field by about 20 years.

  19.  This project offers an immediate and effective way of establishing the necessary large-scale technology demonstration and of helping to meet current emissions targets. When completed, it will set several technology milestones including the:

    —  largest carbon dioxide EOR project in the North Sea;

    —  first carbon dioxide pipeline in the North Sea;

    —  largest hydrogen-fired power generation facility in the world;

    —  largest Auto Thermal reformer for generating hydrogen.

  20.  There is no single solution which can by itself deliver the world's CO2 targets, but there is a portfolio of technologies that have been demonstrated at scale, and which collectively offer the opportunity to make the necessary reductions over the next 50 years. Because the world will be dependent on conventional hydrocarbons for the next 50 years, hydrocarbon-based technological solutions for climate change will be one of the major contributors to stabilisation. DF1, for example, will reduce carbon dioxide emissions by some 80 to 90% for each unit of electricity produced. Indeed, if applied to only 5% of the new electricity generating capacity which the world is projected to require by 2050, the world would have the potential of reducing global CO2 emissions by around 1 billion tonnes a year.

  21.  There are also security of supply implications. The project will prolong the life of the Miller Field through enhanced oil recovery and through the postponement of abandonment (which could eventually be imitated throughout the North Sea). But more important, it demonstrates a viable technology pathway for clean energy production from a broader range of primary energy sources (eg coal, biomass) which would improve energy security.

  22.  In terms of the immediate future, this single project would reduce emissions of CO2 by 1.3 million tons per year (the equivalent of removing 300,000 cars from the roads) and provide around 350MW of clean electricity—which is enough to power all the homes in a city the size of Glasgow or Manchester (250,000 homes).

  23.  DF1 (and other CCS projects) has one other major environmental benefit. It does not require back-up to address the problem of the intermittency of wind or sun. It provides base load capacity, and although it may not be totally carbon free, it provides virtually carbon free energy for 100% of the time.

THE ROLE OF GOVERNMENT

  24.  As stated above, the costs of CCS are similar to renewables. The time has arrived, therefore, to consider seriously whether a Climate Change Policy should not seek to be rewarding low carbon (or carbon free) energy on an objective, impartial basis rather than through the "picking of winners" as exemplified by the current policy which favours renewables. This in no way questions the role of renewable energy initiatives. BP is involved in this area as well, and there is no doubt that a variety of carbon reduction strategies and technologies will be required in order to reduce significantly green house gas emissions.

  25.  But the opportunity offered by DF1 must be instantly grasped if it is to be realised, and therefore the implications for public policy must be recognised equally quickly. This is because DF1 offers the possibility to prove the concept of CCS in the UK and North Sea in a relatively short time frame. This is a critical aspect, for without such timely large scale industrial demonstrations, the UK is in danger of missing the window of real opportunity for this technology in the North Sea. Hence, it is necessary that incentives should be in place quickly which are equivalent to those currently available to no-carbon options. This is not merely to facilitate DF1; and it is not just to demonstrate the technology, important though this is. DF1 also offers the opportunity to develop the UK's policy instruments for cleaner energy. That is why it would be wrong, in policy terms, to approach DF1 as a single stand-alone project. Rather, DF1 should spearhead a policy approach which assures future investors in CCS of a consistent and sustainable approach to their investments.

  26.  There are other issues, in addition to incentives, where government has a role to play. For example, provisions of both OSPAR and the London Convention will need to be discussed. The rules of the European Emissions Trading System (EU ETS) will need to clarified. And new regulations and permits will also be required embracing a number of areas, including approvals for new plant onshore (for pre-, post- or Oxy-firing technology); for pipeline access to move CO2; and for injection of CO2 offshore geological structures under the seabed for EOR and ultimately for storage.

  27.  But over the next 12 months, as UK Energy Policy evolves, it is vital for policy makers to recognise that any credible policy to reduce CO2 emissions must embrace CCS: and that this ought to be acknowledged in any fiscal or regulatory regime designed to assist low carbon or carbon free energy to compete with fossil fuels. BP anticipates that over time—and given increasing scale, experience and technological expertise—the cost of schemes like DF1 will reduce. But that is not the case today, even though CCS is well placed to argue that it is both commercially and environmentally on a par with (if not ahead of) any existing alternative. Obviously, a properly functioning Emissions Trading System would be of enormous benefit to CCS projects—although the specific European system is currently insufficient, even if the rules were to be clarified, because it fails to provide a framework of sufficient duration and the current (and indeed, forecast) level of carbon price is inadequate to encourage business to invest the very large sums required.

CONCLUSION

  28.  There is a wide range of solutions to both the issues associated with energy security, and demands for carbon-free energy. BP strongly supports the ongoing development of renewables to contribute to meeting future energy demand and the security of supply. Moreover, the option of meeting future energy needs through fossil-fuelled generation without the associated carbon emissions can only add to energy security. Such power plants, based on coal or gas both of which have substantial reserves internationally, are controllable and immune from the vagaries of the weather.

  29.  In addition, we believe there to be huge potential for CCS to enable the achievement of apparently conflicting goals at reasonable cost. It is estimated that up to one third of the required reductions in global CO2 emissions could be made by CCS technology. CCS is uniquely placed to help build a bridge to a low or no carbon energy future in the next 50 to 100 years.

  30.  The best policy framework to support these and other options should ideally be non-discriminatory between different solutions. There needs to be a mix of measures which together provide a level playing field of support and incentives for low and zero carbon energy. As has often been recognised, the temptation by government to "pick winners" should be resisted in favour of providing a secure long-term level of non-discriminatory support for anything which helps to both reduce CO2 emissions and, in terms specifically of security of supply, increases the range of energy sources available.
