1 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques EGTEI - Emerging technologies/ techniques for LCPs up to 2030 (LCP > 500 MWth) Pierre Kerdoncuff (French Agency for Environment and Energy Management)

2 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 2

3 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 3 EGTEI was mandated by UN ECE to:  Initiate some work on emerging technologies/techniques in order to assess what could be done technically and economically to reduce air emissions from large combustion plants (LCP) up to 2030 Improvement in the modelling by:  Replacing the current assumption with information from the technical improvements of existing technologies and abatement techniques  Considering the impacts and costs of emerging technologies/techniques on emission reduction over time

4 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 4 Objective of the LCP2030 subgroup  Provide technical and economical information for modelling work on: Emerging technologies and abatement techniques Emerging applications of existing abatement techniques Improvement of existing technologies and abatement techniques “Emerging” techniques or technologies: not yet commercialized or in a early stage of commercialization

5 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 5 Focus on:  Their techno-economic characterisation (environmental performances, efficiency and CO 2 impact, costs, rate of penetration,…)  LCP > 500 MWth  Primary and secondary measures. Combinations of primary and secondary measures or combinations abating several pollutants at a time may also be considered.  PM, SO x, NO x and CO 2 abatement

6 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 6 Methodology:  Identification of documents and studies: IPPC BREF on LCP EU-project “Assessment of the air emissions impact of emerging technologies” 2003/2004 Documents on Carbon Capture and Storage (CCS )  Proposition of a list of potential technologies/techniques and review by the experts in order to identify technologies / techniques to be analysed with high priority  Collect of information from LCP2030 subgroup experts or from interview of other experts

7 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 7 Experts:  Industrial experts: EDF, RWE npower, EDIPOWER, BOT Gornictwo i Energetyka SA…  Administration experts: ENEA, ECN, Swedish EPA, Federal Environmental Agency Austria, Finish Environment Institute…

8 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 8 Main views of the experts on emerging technology

9 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 9  IGCC (Integrated gasification combined cycle) The net efficiency for existing IGCC plants operating on coal is around 43% (LHV basis). IGCC could reach 50% efficiency around 2015. Investment is estimated between 1 and 1.5 M€/MWth (demonstration plant). A study from IEA considers the specific investment of IGCC is about 20% higher than that of pulverized combustion. IGCC technologies could be commercially available around 2020 with CCS.

10 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 10  Oxy-combustion Oxy-combustion enables the capture of CO 2 by direct compression of the flue gas without further chemical capture or separation. Several 10 to 50 MW mock-up plants worldwide are planned up to 2010, with 100 to 500 MW units possible around 2015. Oxy-combustion technologies could be commercially available around 2020. Oxy-combustion process leads to the decrease of NOx emissions.

11 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 11 Main views of the experts on emerging abatement techniques

12 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 12  Flowpac (Alstom) Flowpac is a promising end-of-pipe desulphurisation (wet FGD) technology using a bubbling technology instead of circulation pumps. Flowpac results in a low capital cost. The electrical consumption is lower in the Flowpac (1.3% of the power capacity) than in the classical wet FGD (1.7/1.75%). The system is currently implemented in oil-fired plants (< 340 MWe) and needs to be demonstrated with coal- fired plants.

13 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 13  CO 2 abatement techniques There are three types of CO 2 capture processes: post- combustion, oxy-combustion, pre-combustion CO 2 capture and storage (CCS) in power plants is being demonstrated in a few small-scale pilot plants. Large- scale demonstration plants with CCS are planned by around 2015 with the objective of developing CCS by 2020 CCS costs are highly project specific. The objective is to reduce CCS costs to below 25€/tCO 2 avoided by 2030.

14 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 14 Main views of the experts on improvement of existing technologies

15 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 15  One of the ways of reducing the emissions of CO 2 from fossil fuel fired power plants is to improve the overall efficiency of plants. Because of the penalty of CO 2 capture, CCS makes sense only for highly efficient plants.  The improvement of the following existing technologies were considered by the experts: Coal-fired power plant Combined Cycle Gas Turbine (CCGT)

16 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 16  Coal-fired power plant Sub-critical coal-fired power plants can achieve efficiencies of up to 40% and supercritical and ultrasupercritical of up to 45%. From 2020, coal-fired power plants with advanced steam cycle (350 bar, 700°C) could reach efficiency of above 50%. The challenge is the development of materials (nickel based alloys).

17 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 17  Combined Cycle Gas Turbine (CCGT) The average efficiency of a 400 MWe combined cycle gas turbine (CCGT) is about 58%. In 2015, efficiency of 62% could be commercially available. In 2035, CCGT should reach, commercially, an efficiency of 70% by improving the component efficiencies and using new materials.

18 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 18  Combined Cycle Gas Turbine (CCGT) The increase of efficiency will follow the increase of the capacity of units. At present, the CCGT units (F technology) have a capacity of 430 MWe (in CCGT configuration). Technology of the H generation has a capacity of 530 MWe. Experts assess that the CCGT units could reach capacities of 600 to 700 MWe in the future. The most recently build plants are able to reach 20 mg/Nm 3 without SCR.

19 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 19 In the report, more information is available on:  Emerging applications of existing abatement techniques (SO 3 injection to reduce PM emissions)  Costs and performances of abatement techniques of existing installations  Impact of energy efficiency increase on CO 2 and pollutant emissions  Impact of energy efficiency and plant sizes on costs  …

20 Workshop of St Petersburg - 27 th October 2009 Expert sub-group on Emerging Technologies/Techniques 20 Future work:  Some technologies/techniques (e.g. catalytic combustion), were considered as outside the scope of the LCP2030 subgroup which considered only power plants with capacities higher than 500 MWth.  Future work of the subgroup will consider lower capacities of the large combustion plants (> 50 MWth).
