3 Global coal-fired electricity generation (TWh) Improve efficiency, then deploy CCS Decrease generation from subcritical Install CCS* on plants over supercritical Increase generation from high-efficiency technology (SC or better) *CCS (Post-combustion, Oxyfuel, Pre-combustion CO 2 capture) Subcritical HELE Plants with CCS* Supercritical USC IGCC * CCS fitted to SC (or better) units. 8/14/2014 Energy technology roadmaps OECD/IEA 2012

4 Mt CO 2 reductions from Gt CO 2 reduction by 2050 Reduction of CO 2 emissions from 2010 in the 2DS Reducing electricity from coal-fired power generation driven by policy and regulation Decreasing CO 2 intensity factor driven by technology development 8/14/2014 Technology improvement coupled with targeted policy and Energy technology roadmaps regulation are essential to realise the 2DS target in OECD/IEA 2012

5 Capacity (GW) Contribution from efficiency improvement Share of SC or better (r-h axis) Efficiency improvement achieved by reducing generation from Energy technology roadmaps inefficient units and increasing generation from HELE units. 8/14/2014 OECD/IEA 2012

6 Capacity (GW) Best practice technology to be adopted Potential for capacity growth in coal-fired power generation is Energy technology roadmaps seen mostly in non-oecd countries such as China and India. 8/14/2014 OECD/IEA 2012

7 CO 2 intensity factor (gco 2 /kwh) HELE technologies reduce the CO 2 /kwh for capture Subcritical SC USC Advanced-USC 90% Case with CCS Efficiency (LHV,net) Increasing plant efficiency is important to reduce the cost of CO 2 8/14/2014 abatement. Energy technology roadmaps OECD/IEA 2012

8 Average CO 2 intensity factor in 2DS (gco 2 /kwh) Share of CCS (1=100%) Impact of efficiency improvement on CO 2 abatement Efficiency in 2DS 33% 34% 37% 42% 43% Efficiency improvement CO 2 abatement by CCS 8/14/2014 Raising efficiency significantly reduces the CO 2 /kwh emitted Energy technology roadmaps OECD/IEA 2012

9 Maximum steam temperature ( C ) Advanced technology is essential Advanced-USC 700 o C Demonstrations are being planned from Supercritical Ultra-supercritical Subcritical Ultra-supercritical plants are currently operating in various Energy technology roadmaps countries, particularly in China. 8/14/2014 OECD/IEA 2012

10 The challenge of advanced USC Boiler tube/piping C 700 C/ 30-35MPa C Steam turbine rotor/shaft Boiler Steam turbine ~ Generator - Nickel-based super-alloys - Ferrite/Austenitic alloys 8/14/2014 Nickel-based super-alloys will enable plant components to Energy technology roadmaps withstand temperatures of 700ºC and beyond. OECD/IEA 2012

11 IGCC+CCS may be cost competitive Integrated gasification combined cycle power generation With the latest 1500 C-class gas turbines, efficiencies of 50% (LHV, net) may be achievable, with cost-competitiveness will Energy depend technology on sufficient roadmaps numbers of plants being deployed. 8/14/2014 OECD/IEA 2012

12 Moisture reduction important Advanced lignite pre-drying in pulverised coal combustion RWE Power Vattenfall 8/14/2014 The steam cycle is optimised for maximum efficiency. Energy technology roadmaps OECD/IEA 2012

13 Recommended actions for the near term By 2020, CO 2 emissions from coal-fired power generation must already have peaked to be consistent with the 2DS. Greater efficiencies must be achieved in the power generation sector. Deploying supercritical and ultra-supercritical technologies, both available now, will be important. Even higher efficiencies will be achieved as A-USC and more advanced IGCC become available. Power generation from low-grade coals, such as lignite, can be much more efficient. CCS must be developed and demonstrated rapidly if it is to be deployed at a scale sufficient to achieve the 2DS. 8/14/2014 Energy technology roadmaps OECD/IEA 2012
