CO2 and Clean Coal

Future Needs for Energy Research Infrastructure

Tony Kaiser

- Add text to be highlighted here -

Long Term Energy Market

IEA projections of global power stations to be built by 2030


IEA World Energy Outlook 2003

Continuous reliance on fossil fuels

  • especially likes of China and India

  • Different needs world-wide

    • uneven access to modern energy

  • Growth of Renewable Energy but ….

Long Term Competitive Position

IEA projections of global power station to be built by 2030

  • Huge growth in China

    • inward investment in capability

    • Chinese equipment suppliers likely

      to become world players

      eg Steam Turbines companies (like Shanghai and Harbin) have annual capacity of over 30 GW

IEA WEO 2004


  • Europe will face harsh competition

    • global markets

    • not just from USA and Japan

    • but also increasingly from Asia

Continuous need to develop the technology – focus on high added value components and systems

Market Intelligence / Trends / TR190 JW1 / 980531

  • Improve “business as usual”

  • fuel switch to less carbon-intensive fuels

Technology Solutions: Increasing Efficiency of Thermal Power

Potential co 2 reduction in eu
Potential CO2 Reduction in EU

Power Plant Efficiency Evolution

  • Plant efficiency has improved steadily over the years

  • Efficiency increase from Subcritical to USC can, for example, yield up to 30% CO2 emissions reduction




CO2 Capture Options

  • Pre-combustion Front End

    • IGCC based systems

    • Carbonate capture

    • Chemical looping

  • Oxygen Combustion

    • Internal (membrane) or external (ASU) oxygen supply

  • Post Combustion “Tail-end” CO2 capture

    • Absorption/stripping process using MEA, physical absorbents …..

Towards Zero Emissions at the right price

Post combustion capture with exhaust gas recirculation
Post Combustion Capture with Exhaust Gas Recirculation

  • Allows increase in CO2 concentration in exhaust gas

Strategic trajectories
Strategic Trajectories

Flexible strategy to cover uncertain future

`Zero Emissions`




Value of CO2?





High efficiency combined with `Capture ready` concept?





FP7 - Importance of Energy

  • Energy RTD and D is a critical issue for future in Europe and world-wide

    • Wide range of drivers : Competitiveness, Market Need, Security of Supply, Environment, Global Climate Change, ……..

    • Needs to be a recognized identified theme in FP7

    • Needs to have a significant budget assigned in FP7

  • Portfolio approach needed in FP7 for Energy RTD and D

    • Non-nuclear energy programme needs to be comparable with that of Euratom/Nuclear

    • Renewable Energy, Hydrogen/FCs, Networks/T&D, Energy Efficiency, Storage ……… and

    • Clean use of fossil fuels (= near zero emission power generation)

Importance of a balanced approach to Energy RTD & D

Helicopter viewpoint
‘Helicopter’ Viewpoint

  • All measures will be required

    • different solutions in different parts of the world

  • Not one single winning technology

    • complementary actions

  • Broad portfolio approach necessary

    • energy efficiency, REN, fossil, nuclear

  • Development of energy technology will be essential

  • Clean use of fossil fuels: a critical transitionfor decades yet, in getting to a sustainable energy future

General issue demonstration and upscaling of technologies
General issue – Demonstration and Upscaling of Technologies

  • Small scale test rigs are readily available in EU

  • EU-Funding of Upscaling of Technology and

  • Large scale Demonstration of Technology

  • Need for energy infrastructure and demonstrator projects to

    • better deployment energy technologies,

    • reduce technical risks,

    • Show economical competitiveness

      • See e.g. U.S. with “FutureGen”, H-Class GT….
