  1. “ENCAP” Enhanced Capture of CO2 Status: July 2005 Dr. Ciattaglia

  2. Project costs : 22,2 Mio Euro (EC Contribution: 10,7 Mio Euro) • Start : March 2004 • Duration : 5 years • Some partners: • for power station operation: Vattenfall, RWE • for power station construction/turbines: SIEMENS, Alstom • for oxygen generation/supply: Air Liquide, BOC, Linde • for processing/engineering: Lurgi, Mitsui Babcock, Statoil, Linde • for material testing/developing: SINTEF, TNO, Uni Twente, IFP

  3. Project Overview • Progresses

  4. ENCAP targetsare the enhacement of CO2-capture efficiency and the reduction of CO2-capture costs. • Project goals • Development and optimisation of emerging CO2-capturetechnologies and • processes for power generation based on fossil fuels meeting the following • targets: • at least 90% CO2-capture rate • 50% CO2-capture-cost reduction • Reference: 50-60 Euro/t captured CO2.

  5. ENCAP timing consists of two main phases. • Project timing and structure • Timing: five years (2004-2008), 2 phases, start of project: March 2004 • Phase I: research and basic experimental activities on candidate technology concepts (months 1-30). • Phase II: research and large scale verification of one/two candidate technology concepts selected on the basis of Phase I results.

  6. ENCAP is structured in six sub-projects, SP. • Structure • RTD activities structured in 6 sub-projects (important participants): • SP1 Process and Power Systems (Vattenfall, RWE,Siemens, Alstom, Linde LE) • (definition of power plant processes, reference plants, bench marks) • SP2 Pre-Combustion Decarbonisation Techn. (RWE, Lurgi, Siemens, AirL) • (IGCC, IRCC, oxygen from an cryo ASU) • SP3 OxyFuel Boiler Technologies (Vattenfall, AirL., Mitsui Babcock Energy) • (coal, natural gas with oxygen from an cryo ASU) • SP4 Chemical Looping Combustion (Alstom, SINTEF, IFP,TNO) • (oxygen transport by metal oxides) • SP5 High-Temperature Oxygen Generation for Power Cycles (BOC, Statoil, • SINTEF, TNO, Univ. Twente, Linde LE), SP Leader: LINDE LE. • (membrane developments) • SP6 Novel Pre-Combustion Capture Concepts (Alstom, Siemens, AirL)

  7. SP5 is focussed on the development of high-temperature oxygen generation systems. SP5: High Temp. Oxygen Generation for Power Cycles Goals: identification, evaluation and ranking of promising high temperature oxygen generation process options, to be effectively integrated in power plant cycles with CO2 capture. Organisation: 2 phases phase I: development of three promising high temperature oxygen generation routes, based on ceramic materials and either O2-transport or O2-storage, to enable economic comparison and selection of the most promising option (first 18-months) phase II: further validation of the selected option

  8. SP5 is structured into five interacting work packages SINTEF TNO UTwente WP5.2 Oxygen separator membrane WP5.1 Oxygen process selection and integration WP5.5 Stability definition of materials Linde Siemens RWE WP5.3 CAR process TNO SINTEF UTwente BOC AP WP5.4 Oxygen transport membrane Statoil

  9. Project Overview • Progress

  10. A selection procedure for the identification of the most promising integration power plant scenario was defined • WP5.1 Oxygen process selection and integration • Definition of a stepwise procedure for the selection of one most promising power plant with integrated high T oxygen generation system (Milestone month 18). • First economic evaluation of preselected, most promising scenarios with integrated oxygen generation systems.

  11. Material screening, testing and characterisation were focused by WP5.2 and WP5.3. • WP5.2 Development and validation of oxygen separator membrane for power plant cycle applications • Selection of the basis composition CaTiFeO for the development of a membrane system dense layer + porous support. • Identification of the methodologies for membrane system manufacture. • WP5.3 Development of CAR process • Identification of new materials with oxygen recovery capacity exceeding by a factor 3-6 the standard CAR materials and allowing a decrease in the process temperature by about 200 °C. • Found the phenomenon of “restoration” of perovskite structures enabling thus extended material life time.

  12. Principle of the CAR Process(Ceramic Autothermal Recovery)

  13. The integration of the OTM unit in power plan was the main issue of WP5.4 • WP5.4 Reactive oxygen transport membrane system • Calculation and upgrading of a power plant concept with integrated OTM-reformer reactor or OTM separator • Feasibility study on OTM + reformer reactor • Data on material and on long term stability tests were collected before ENCAP • WP5.5 Stability evaluation of high temperature oxygen generation methods • Intensive work on WP5.3 materials • Experimental confirmation of the “restoration” phenomenon (SINTEF) • Stability tests (“accelerated life-time tests”, Twente)

  14. Month 18 is SP5 next critical milestone. Next steps for SP5 Month 18 Month 30 WP5.1 Process integration WP5.2 Oxygen separator WP5.3 CAR process WP5.4 Oxygen reactor WP5.5 Stability issues Phase 2: Validation of the selected process Design concept of a scaled-up test unit for this process Key Milestone: Selection process option
