1 What Kind of Electric Power Plant Do We Want for Glades County? (Global Warming & Sea Level Rise Issues) John Capece, Ph.D. Agricultural Engineer December 21, 2006

2 This would be the first U.S. ultra-supercritical pulverized coal (USC-PC) combustion system. It is a cleaner, more efficient process than older pulverized coal technologies. Presentation Objective – USC or IGCC Coal Power Florida Power & Light (FPL) plans to build a coal-fired power plant for completion by 2012 in Glades County, Florida between Hwy 78 and Hwy 27, a few miles northwest of Moore Haven. This power plant will have an expected operating life through 2050.

3 To facilitate carbon dioxide capture and sequestration in the coming decades, many people are advocating using an even more advanced coal technology – IGCC (Integrated Gasification Combined Cycle). This presentation explains the rationale for IGCC, while recognizing that an even better long-term solution to the power needs of our society is the promotion of renewable, distributed energy systems (solar, tide, wind, conservation, etc.). Presentation Objective - I.G.C.C.

6 Electric Power Sources in Florida Why use Coal? Why use Coal? –To balance sources. –Natural gas is risky because of hurricanes. –Large domestic coal supply. (some imported) –No military risk to secure fuel supplies. –Efficient rail transport from Appalachian Mountains. Problems with Coal Problems with Coal –Mining impacts in Appalachia –Mercury & other emissions –Carbon Dioxide emissions

7 CO2 and Temperature Historical Trends

8 Atmospheric Carbon Dioxide Trend

9 CO2 and Temperature Historical Trends We have increased CO2 concentrations beyond any levels ever experienced by modern man. Absent other offsetting factors, temperatures will continue to rise, following from CO2 increases. You will see CO2 pass the 400 ppm level in the next 10 years

10 The Relationship between CO2 and Temperature However, during the past 20,000 years, CO2 followed from temperature, This would match a climate model in which the climate process was being driven by changes in incident solar radiation and changes in the earths reflectance. Probable explanations of CO2 following temperature are out- gassing from warming oceans, CO2 from warming soils, etc. This demonstrates a feedback loop between temperature and CO2/methane that should cause even greater concern today as a magnifier of the current trend. Global Warming asserts that temperature is now following from CO2.

11 The Relationship between CO2 and Temperature Possible causal factors for past glacial & warming cycles: (short term cycles – within the past 700,000 years) (long term cycles – millions of years) solar radiation intensity cycles ocean circulation disruptions ocean circulation disruptions albedo (Earths reflectance) feedback from snow & ice albedo (Earths reflectance) feedback from snow & ice volcanic activity (release of gases) continental plate movements (tectonics) continental plate movements (tectonics)

22 The Major Global Re-insurance Companies See it Coming (Lloyds, Swiss Re, Zurich Re, Munich Re, etc.) Swiss Re: In a carbon constrained imminent future, greenhouse gas emissions will become financial liabilities on many companies balance sheets. The Swiss Re report projected a likely worldwide doubling of losses from weather related causes within ten years to $150 billion dollars US annually. (It is and will continue to affect insurance rates in Florida.) The Climate Change Performance Index, introduced by Germanwatch and Climate Action Network Europe (CAN Europe), compares the climate protection efforts of 56 industrialized and rapidly industrializing countries, that together make up more than 90% of global carbon dioxide emissions. Sweden is the leader, and the USA ranks among the bottom five.

23 Relative Risks Climate change is perhaps the most serious risk faced by our society. History demonstrates that some risks are underestimated by an order of magnitude: Tsunami (ex:Indonesia), Floods (ex:Bangladesh), and Earthquakes (ex:China). Ten-thousand Hundred-thousand Ten-million Hundred-million

24 Are we building our population and quality of life by unsustainably consuming our foundation assets? 6.6 billion people Stable, optimal climate Stable communities Stable agriculture We can follow and survive in an extreme consumption model only if we constantly seek and find new resources and aggressively develop and use new technologies. But it does come at a cost in the form of loss of heritage (ecosystems, species, landscapes, cultural diversity, etc.) Stable eco-systems

25 Carbon Dioxide from Electric Energy Production FPL emits 20% less CO2 than the industry average. This partially reflects the fact that other U.S. regions & companies use more coal, while FPL uses more natural gas. FPL emits 20% less CO2 than the industry average. This partially reflects the fact that other U.S. regions & companies use more coal, while FPL uses more natural gas.

26 Soot & Global Dimming Particulate Matter & Other Emissions (including coal soot) Particulate Matter & Other Emissions (including coal soot) –Estimated to have reduced Global Warming by half, so far. –Reduced incident solar radiation by 5 – 10% worldwide. Is clean coal actually better coal…from a global warming perspective? Is clean coal actually better coal…from a global warming perspective? – High CO2 emissions. – No more soot emissions to offset the CO2 effect.

27 Pulverized Coal vs. Coal Gasification Pulverized Coal – Ultra Super Critical Pulverized Coal – Ultra Super Critical –Burn coal dust to heat water and make steam. –Use steam to drive a turbine. –Steam turbine generates electricity. Gasification – IGCC (Integrated Gasification Combined Cycle) Gasification – IGCC (Integrated Gasification Combined Cycle) –Integrated Gasification and Combined Cycle. –Cook coal to make coal gas. –Burn coal gas in a turbine to make electricity (like a jet engine). –Use the hot coal gas combustion exhaust to heat water and make steam. –Use steam to drive turbine. –Steam turbine generates additional electricity.

28 The most advanced pulverized coal plant (Ultra Super-Critical) is more efficient. USC has 44% Efficiency

34 Pulverized Coal vs. Coal Gasification Gasification – IGCC Gasification – IGCC –Provides easier opportunity to capture CO2. –Cheaper than pulverized coal if CO2 capture is required. Pulverized Coal – USC (without CO2 Capture) Pulverized Coal – USC (without CO2 Capture) –Plants are cheaper to build. –Plant operations are simpler, cheaper, and more reliable. –Plants are smaller and require less land.

The MOU also calls on the federal government to provide financial support for the development of IGCC plants.

44 HR-5049 (in 109 th Congress) a CARBON TAX will be imposed to reduce greenhouse gas emissions How much will the tax be? ($16/ton, phased) $0.50 per gallon of gasoline = $200 per tonne C The amount of a C-tax affects coal & natural gas. The tax has little or no effect on nuclear, solar, wind and other renewable energy sources.

45 Passage of carbon tax framework legislation is likely in the next (110 th ) Congress. Then new chairs of the environment & energy committees sent President Bush a letter immediately after the election.

46 Effects of Carbon Taxes to Achieve CO2 Reduction

47 Other Nations Take Action on Carbon Dioxide

48 U.K. Government Official Policy Statements Climate change is the greatest market failure the world has ever seen.Climate change is the greatest market failure the world has ever seen. The investment that takes place in the next years will have a profound effect on the climate change that happens in the second half of this century and in the next. Extensive carbon capture and storage will be necessary to allow the continued use of fossil fuels without damage to the atmosphere. If we take no action to control emissions, each tonne of CO2 that we emit now is causing damage worth at least $85. Action on climate change will create significant business opportunities, as new markets are created in the low-carbon energy technologies and other low-carbon goods and services.
