International G8-Expert Workshop on Clean Coal Technologies, Leipzig, 6th March 2007
Prof. Kurt Haege, Leipzig, 6th March 2007 2
Challenge of Climate Change(Source: 4th Assessment Report of IPCC, WG1, Feb. 2007)
The 2nd half of the 20th century was the warmest period of the last 500 years.The average sea level rise of the 20th century was 17 cm.
A Global solution with long term commitments is needed. ZEP takes an active role to accelerate governments and global institutions towards practical solutions.
WG1: The Physical Science Basis
WG2: Impacts, Adaptation and Vulnerability
WG3: Mitigation of ClimateChange
Prof. Kurt Haege, Leipzig, 6th March 2007 3
Future Role of Fossil Fuels
• Fossil fuels - global use will increase during the next decades
• The CLEAN COAL concept fits in the context of climate protection as well as security of supply
• The Technology platform ZEP wants to give a major thrust to the development of the CO2-free power plant.
Prof. Kurt Haege, Leipzig, 6th March 2007 4
Strategy on Climate Change
• Renewable energy sources
• Increased efficiency in generation and utilisation
• Options for the future: CO2 capture and storage
• Active partner in the international climate dialogue
ZEP Strategy:
Prof. Kurt Haege, Leipzig, 6th March 2007 5
ZEP Set-up and Vision
• Primary task to set strategic research agenda (SRA) and deployment document (SDD) as major input to EC FP7 (2007 - 2013)
• Advisory Council formed in June 2005
– 6 Generators: E.ON, Endesa, Enel, Energi E2, RWE, Vattenfall – 6 Equipment suppliers: Ansaldo, ALSTOM, Air Liquide, Foster Wheeler,
• Developing new concepts already identified, but not validated, fordemonstration by 2010-2015 and implementation beyond 2020
• Supporting long-term exploratory research into advanced, innovative concepts for implementation of next-generation technology by 2050
• Maximising cooperation at national, European and international level
• Strengthening and accelerating R&D priorities to support the Strategic Depolyment Document, informed by experience fromdemonstration projects and parallel R&D projects.
Prof. Kurt Haege, Leipzig, 6th March 2007 9
The Strategic Deployment Document outlines how to accelerate the market for efficient zero emission power production.
SDD Recommendations
• Kick-starting the CO2 value chain with urgent short- and long-term commercial incentive
• Establishing a regulatory framework for the geological storage ofCO2
• Gaining public support via a comprehensive public informationcampaign:
• Establishing robust RD&D funding under the FP7 and nationalprogrammes:- Improve energy conversion efficiency, reduce cost and reduce scale-up risk of CO2
capture technology
-Undertake EU-wide mapping of large CO2 sources and geological storage
-By 2008, establish a “Joint Technology Initiative” as part of a portfolio of mechanisms formaximising European co-operation.
Prof. Kurt Haege, Leipzig, 6th March 2007 10
A Three Phase Argumentation
• Reducing emissions and increasing efficiency in ecologically andeconomically optimised steps
– Modernisation of existing plants: SO2, NOx, dust, retrofit
– Construction of new state-of-the-art power plants
• Development of high-efficiency power stations with the aim to minimise consumption of resources and reduce specific emissions,particularly those of CO2
• New Technologies for CO2 capture and storage
Prof. Kurt Haege, Leipzig, 6th March 2007 11
Current Efforts to Increase Power Plant Efficiency
• COMTES 700: material and component test for 700 °C technology (joint project of VGB, generators, equipment suppliers and EU)
• Fluidised-bed drying process for lignite (RWE Power)
• CCGT-Project Irsching to increase net efficiency up to 60 % (Siemens, E.ON)
• Efficiency improvements by replacement of existing steam turbines by new turbines with 3D-designed blades (retrofitting)
• Further increasing of net efficiency of PC-boilers by development of materials for live steam parameters of 750 °C and more (COORETEC, BMWi)
+ 4 %(compared to 600/620 °C,
275 bar live steam)
percentage points
+ 4 %(43 → 47 % - net)
+ 1,5-2 %( 58 → 60 % - net)
+ 5 %(→ 55% - net)
Depending on individual case
Objectives: Efficiencies of more than 50 % for steam power plants and above 60 % for gas turbine plants
Prof. Kurt Haege, Leipzig, 6th March 2007 12
Main Technology Options for CO2Capture from Power Plants
Three technologies seem capable to fulfil the primary target to 2020
• All largely contain known technology and components
• All need optimization, scale up and process integration
• Power process efficiency increase is always a supporting activity
1. Close cooperation with EU to identify regulatory issues• Regulatory work DG TREN, ENV, …• Public funding for R&D (FP7, JTI,
EIB, …)
2. Coordinate between ZEP TFs, EC and national governments
3. Develop commercial incentives4. Ensure that CCS is introduced under
ETS5. Propose regulation corresponding to
GHG avoidance costs6. Map MS’ involvement and
disseminate best practice
PUBLIC COMMUNICATION
1. Develop and execute communication strategy• Educational task• Political debate/parliament
2. Push implementation of CCS in Member States
3. Involve NGO’s 4. Ensure transparency and
communication of results
Prof. Kurt Haege, Leipzig, 6th March 2007 23
• Less than 10 % heard of CCS.
• Before explanation only 13 % were positive, after explanation 55 % agreed.
• Public - even when they are concerned about climate change - do not immediately accept CCS. Those that were positive in general terms were neutral to negative about storage in their neighbourhood..
• Although the public worries about climate change it will accept only minimal energy price increases.
An early information campaign is necessary to get public support for the large scale implementation of CCS.
Public Acceptance of CCS(Source: ZEP – WG5)
Prof. Kurt Haege, Leipzig, 6th March 2007 24
Expected Support of EC/Politics (1)
• Clear commitment to coal as important part of the future energy mix
• Clear commitment to CCS as instrument for CO2 mitigation to stop climate change
• Support of efficiency increase to minimise consumption of resources and as pre-requisite of ZEP
• Create legal framework for geological storage of CO2: amendment of EU waste and water framework directive and amendment of national mining law
Prof. Kurt Haege, Leipzig, 6th March 2007 25
Expected Support of EC/Politics (2)
• Support and active cooperation in public relations to get the acceptance for ZEP
• Sufficient financial support of the ZEP recommendations within SRA and SDD to allow for the necessary R&D and to set out for 10 - 12 demo projects
• No preference for renewable energies within the European FP7
• Close collaboration in ETP-ZEP and in continuation of German COORETEC initiative
Prof. Kurt Haege, Leipzig, 6th March 2007 26
Summary
• Coal will remain its worldwide importance for electricity generation.
• Coal has to be used even more efficient and environmental friendly.
• Precondition is the large scale test of efficiency increasing technologies like integratedcoal drying and raised steam parameters as well as CO2 capture and storage.
• The necessary time-frame is about 10 to 15 years. Joint development projects make iteasier to be successful.
• CO2 capture and storage is a promising option to secure the future of power generation based on fossil fuels. It doesn’t reduce, however, the necessity of CO2 avoidance through further efficiency increases
• The technical feasibility of ZEP technologies is beyond dispute.
• The economic efficiency will depend on the polital frame-conditions.
