Enel's CCS Project Current Status Overview

  1. 1. Enels CCS ProjectCurrent Status OverviewStefano MalloggiRoma, 18 ottobre 2011
  2. 2. Uso: AziendaleZEPT Post-combustion capture and storage demo project Project goal To retrofit one 660 MWecoal fired unit of Porto Tolle Porto Tolle power station with CO2 P2 Porto Tolle capture equipment and start CO2 undergroundstorage by the end of 2015 P1 2
  3. 3. Uso: AziendaleP.To Tolle demo projectMain features of the demo plant • Flue gas flow rate: 810.000 Nm3/h • Capacity: 1 Mt of CO2 per year (250 MWe equivalent) • Capture technology: post combustion ammine based Porto Tolle P2 • CO2 removal efficiency: 90% Porto Tolle • Storage: deep saline aquifer off-shore (about 100 km from the power plant) • Plant in operation: by the end of 2015 P1 3
  4. 4. Uso: Aziendale ZEPT Post-combustion capture and storage demo project General planning (*) 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 Capture process testsPhase 1 Technology follow-up at lab scale Design and construction of a Operation of the capture pilot plantPhase 2 10.000 Nm 3 /h pilot plant and pilot tests on transport & injectionPhase 3 Geological studies for site selection Geological storage site characterization and preparationPhase 4 Feasibility study, design and construction of a CCS demo plant (*) time schedule subject to be modified in relation to P.to Tolle Power Station authorization procedure 4
  5. 5. Uso: Aziendale CCS – The main activities in progress•1 Feasibility study of P.to Tolle demo project • Selection of the capture technology • Development of the FEED(*) for transport pipeline and injection infrastructure • Selection and assessment of the storage site • Development of the financing plan•2 Sorbent characterization • Pilot scale test of MEA sorbent (*) Front End Engineering Design 5
  6. 6. Uso: Aziendale1 P.To Tolle demo project - Feasibility Analysis Selection of the capture technology Front End Engineering Design Power Unit Capture Compression and Injection Deep saline - Process Flow Diagrams e Process & Instrumentation Diagrams transport aquifer - Mass & energy balance CO2 path - Detailed design of: main components and Cap rock – 1 km key items, civil works, electric system and automation impermeable layer CO2 - Materials - Plant general lay out and lay out of piping Work flow - Quantities and weights Selection of the process and conceptual design - Planning of engineering and mounting development - Investment cost (construction Selection of the potential technology providers by engineering, R&C international level survey system, components, piping, civil works, BOP, mounting, ecc) and O&M cost Definition of a scoring matrix and selection of the top 4 by evaluation (chemicals, ee, water, spare parts, ecc) a question&answer procedure Development of 4 FEED and• selection of the BAT for capture and compression section• Test of the sorbent used by the selected tecnology provider on the 10.000 Nm3/h pilot plant of Brindisi 6
  7. 7. Uso: Aziendale 1 P.To Tolle demo project - Feasibility Analysis Selection and assessment of the storage sitePre-screening completed. Selected areservoir with an estimated capacity of 200Mt of CO2(*) Activity Flow chart 1. Data Porto Tolle assessment Power plant and base line 4. Appraisal well 2. Geological construction and site modeling injection test and appraisal well design (2013) 3. Risk analysis(*) able to storage the total CO2 mass rate of the power Activities instation for 25 years progress The activities are carried out in collaboration with eni and italian/international scientific institutions (INGV, OGS, CESI, IFP, Schlumberger) 7
  8. 8. Uso: Aziendale 2 CO2 capture pilot plant HighlightsActivities Main features Start up and commissioning July 2010 Three experimental campaigns performed:  baseline tests with MEA 20%wt  parametric tests with MEA 30-40% wt  reclaiming tests  emission measures Numbers:  2500 h of operation  Flue gas flow: 10.000 Nm3/h  5000 ton of CO2 captured  Capture capacity: 50-60 t CO2/day  Capture efficiency: 85-95%  More than 200 visitors in six months (after  Absorption temperature: 45-50 ºC inauguration)  Desorption pressure: up to 2.5 barg  CO2 purity: >99%,vol  SO2 at capture section inlet: < 20 mg/Nm3  8 particulate at capture section inlet: < 0,25 mg/Nm3
  9. 9. Uso: Aziendale 2 Brindisi pilot plant - MEA test results ~17% ~26% MEA 20% MEA 30% MEA 40% Gj/ton CO2Gj/ton CO2 MEA 20% MEA 30% MEA 40% Campaign Gj/ton CO2 % MEA 20 % 4,1 0 Solvent flow rate - mc MEA 30 % 3,4 - 17 MEA 40 % 3,02 - 26  MEA 40 % reduction over 25% compared to MEA 20 % and over 15% respect to MEA 30% 9
  10. 10. Uso: Aziendale 2 Reduction of the energy impact increasing the capture process performance New technology development path Ammine based sorbents (now in Brindisi pilot and in PT demo in the future) • In the first phase the research activities 14 LIQUID will be focused on the ammine based SORBENT sorbents (used in P.to Tolle application) 12 Mid-Long term • In the second phase the objective willLoss of efficiency (%) 10 tecnologies (ex. solid be to characterized and select 2nd sorbents, membrane, ion ic liquid, hydrates) generation sorbents potentially suitable 8 for improving the capture process 6 New sorbents (dual performances. The goal is to reduce the phase, ammino-acid, new energy impact of CCS on the generation ammine mix, ammonia) 4 unit in the range 40%-50% (for commercial plant built after 2025) 2 Technologies Enel conseders of interest in the short-mid term period 5 10 15 20 years The different sorbents will be tested on the pilot plant of Brindisi since 2011 with the aim of verifying the energy penalty (mid term objective: reduction of 40%) 10
