6 Average Coal-Fired Power Plant Efficiencies China, India, and USA Country Average Efficiency (HHV) (%) OECD 36 USA China ~30-32 India ~25-34 China s reported power efficiency is approaching OECD levels following rapid build up of new units over the last 5+ years India is improving too but not as fast as China owing to slower build up and the number of poor performing SEB stations, which represent about 2/3 of India s electricity generation 6

7 China is shifting rapidly to advanced coal technologies Average efficiency of coal-fired generation: 33.2% LHV Over 8,000 small, low-efficiency units <200 MW First 350 MW subcritical unit commissioned in 1982, first 600 MW subcritical unit in 1989 Has been building mostly large ( MW) subcritical units Focus shifted to add large supercritical and ultrasupercritical units 3% of existing (30 units) and 9% of planned capacity with goal of 50% of new capacity by 2020 Domestic units of 600 MW under demonstration and imported 1,000-MW units under construction Ultra-supercritical units 4 x 1000-MW units recently commissioned 7

8 India is adopting advanced technologies more slowly Average efficiency of coal-fired generation: 27.6% LHV Poor quality coal (>40% ash) limits performance Currently, 100% subcritical pulverized coal 135 x MW units since 1978 and 27 x 500 MW since 1984 commissioned by BHEL 1 st supercritical plant (3 x 660 MW) under construction at Sipat using South Korean technology Ultra-mega projects planned using 800-MW supercritical units 8

9 Environmental Regulations in China Focus on SO 2 and NOx New SO 2, NO x, and PM Emission Standards (1/1/04) SO 2, NO x, and PM standards within World Bank guidelines SO 2 standards, on par with OECD average, require use of low-sulfur coal and FGD controls Goal: FGD at 60% of thermal capacity by 2010 Government focus on developing cost-effective FGD systems NOx standards relatively modest compared to OECD Can be satisfied by Chinese low-nox burners but have begun importing SCNR and SCR systems PM emission standards require high-efficiency ESPs 9

10 China has installed SO 2 scrubbers at an astounding rate since China coal power Capacity (GWe) US. coal power China SO2 scrubber 100 US. SO2 scrubber Year 2006 and 2007 in China: Power plant addition 100 GW/yr Scrubber installation 100 GW/yr Slide Source: Professor Socolow, Princeton University 10

11 Environmental Regulations in India India does not have SO 2 or NOx stack emission standards for coal-fired power generation India does have PM emission controls and ambient air standards Government focus on improving overall coal conversion process: Reduce ash content of coal Build larger, more efficient units Renovate and modernize existing capacity Build plants closer to mines 11

12 Coal Technology Status in China and India Technology China India IGCC Gasifiers CFBC Yantai IGCC project under consideration for past decade. Several power and polygeneration projects being developed by major utilities. 37 on coal, 13 on petroleum and 1 on gas (25 Shell, 22 GE, 3 Sasol Lurgi, 1 GTI U-Gas) (35 Operating, 16 Planned) Many domestically built MW units $2.5-M DOE/USAID/NTPC feasibility study for 100-MW unit completed. Pursuing a demo project of about 100 MW by NTPC. BHEL developed domestic technology, tested at 6- MW scale. 6 operating on petroleum and petcoke (5 Shell, 1 GE) Technology acquired through licensing. Four domestically built 125-MW units, including 2 firing lignite. 250-MW unit under installation at Neyveli Lignite. CTL/ Polygeneration Supercritical Ultra Supercritical First phase of Shenhua s direct liquefaction plant in Inner Mongolia to start operation in 2008, producing 1.08 million tons of liquid products (diesel, LPG, and naphtha). Total production of two phases is 5 million tons. Also, developing two indirect liquefaction plants with Sasol Polygeneration under study by others, including Hunnan International Technopolis Shenyang (HITS) using coal and waste/garbage and Datang Power (4 plants) using coal Several dozen units commissioned First plant commissioned early 2008 (Huaneng s 4 x 1000-MW Yuhuan Plant) Under study; on January 2007, Investment Commission said go forward, but not a near-term project Original license from Combustion Engineering (USA, now Alstom); scaled up by BHEL. No units constructed yet, but first plant announced by BHEL and TNEB for 2 x 800 plant at Tuticorin, Tamil Nadu. First imported unit 1980-MW (3 x 660 MW) Sipat to be commissioned in 2008 by Doosan Babcock (Korea), which will burn 43% ash coal. Three other projects already awarded to IPPs through tariff-based competitive bidding. Many more supercritical units in pipeline. Initial tie-up with Babcock Borsig. Recently, licensed Alstom boiler technology and Siemens steam turbine technology up to 660 MW. BHEL plans to develop up to 800 MW. No units constructed yet. 12

13 Thermal Power Technology R&D Priorities China R&D and manufacture of >600-MW SC/USC p.c. units Import state-of-the-art control technology for NO x and SO 2 Introduce large-scale gasification and coal liquefaction Polygeneration of Fuels & Power Focus on Chinese manufacture to control costs by: transfer foreign technologies to select equipment manufacturers via licenses and joint ventures participating in international R&D projects India Introduce large (660-MW) SC and USC plants Promote utilization of IGCC and CFBC Renovate and modernize old units License foreign technology 13

14 Institutional Capacity for Fossil Fuel RD&D and Technology Adoption Much Greater in China than India Entities Involved in Fossil Fuel RD&D and Manufacture Research Institutes Universities Conventional Technology Manufacturers China Many (w/commercial companies) Many (w/commercial companies) Many India Few Few Two Advanced Technology Manufacturers Few One Government Funding for R&D Significant Limited Government Ministries Responsible for RD&D and Technology Adoption Responsibilities divided (MOST supports R&D and NRDC supports commercialization) Responsibilities overlap (Ministries of Coal, Mines, Power, Petroleum & Natural Gas, and Dept. of S&T) India Note: NTPC has broke ground on national Energy Technology Centre and BHEL has announced 300 crore ($75M) CCT R&D Centre 14

15 DOE s Office of Fossil Energy Advanced (Coal) Power Systems Goals 2010: 45-50% Efficiency (HHV) 99% SO 2 removal NOx < 0.01 lb/mm Btu 90% Hg removal 2012: 90% CO 2 capture <10% increase in cost of electricity (COE) with carbon sequestration 2015 Multi-product capability (e.g., power + H 2 ) 60% efficiency (measured without carbon capture) 15

16 2007 World Gasification Survey Highlights What is: 3 Sasol plants in South Africa account for over 30% of world gasification production China has 35 operating gasification plants (11 new since 2004) with total syngas output of about 18% of worldwide production What is Planned: 16 new plants planned for China - 7 in start up growing to almost 25% of worldwide production In terms of product, Fischer Tropsch liquids will have largest share of planned growth, most of which is from single gas-to-liquids project in Qatar 15% of worldwide production 16
