  1. Energy and South Carolina Trish Jerman September 2008

  2. S.C. Energy Office Mission To increase energy efficiency and diversity, enhance environmental quality and save energy dollars for South Carolina.

  3. Programs • Transportation Alternatives • Renewable Energy • Energy Efficiency • Energy Education and Outreach • Radioactive Waste Disposal • Energy Planning and Forecasting

  4. South Carolina energy overview • No conventional energy resources -- no coal, no oil, no natural gas and no uranium. • Highly dependent on coal and nuclear power for electricity, and oil for transportation fuel.

  5. S.C. energy statistics • Spend nearly $20 billion on energy annually • Rank 15th nationally in total energy consumption per capita

  6. S.C. total energy consumption

  7. S.C. total energy consumption by fuel type South Carolina United States

  8. S.C. total end-use energy consumption by sector South Carolina United States

  9. Electricity in South Carolina South Carolina: • Spent $5.5 billion on electricity in 2007. • Is 5th in nation in electricity consumption per capita. • Is 10th highest in the U.S. in average residential electricity bill. • Averaged just under eight cents per kWh in 2007 across all sectors, 16th lowest in the country.

  10. Electricity generation by fuel source South Carolina United States

  11. Natural Gas According to EIA, more than ¼ of S.C. households use natural gas as primary home heating source Cleanest burning of the fossil fuels

  12. Emissions – Pounds per billion Btu of energy input Source: EIA

  13. Recent Growth in Natural Gas Production in the Lower 48 States Breaks with Historical Trends

  14. Natural gas reserves growing • Total U.S. proven natural gas reserves have grown about 10% over the last 10 years

  15. Onshore production increasing • Nearly 65% increase in production from “unconventional” sources. • Gas shale production has increased more than 200% from 1998-2007. • Actual “unconventional” production regularly beats EIA yearly outlook estimates.

  16. Abundant onshore supply This map shows 23 prominent gas shales in North America.

  17. Current shale estimates • In 2007, a natural gas assessment stated that U.S. shales contain roughly 1,680 trillion cubic feet (Tcf) of natural gas. • That represents an 88-year supply assuming 2007 production levels.

  18. S.C. served by two large pipelines Southern Natural Gas Transcontinental Natural Gas (TRANSCO) Natural Gas – Transport

  19. Southeastern Natural Gas Pipelines TRANSCO Southern

  20. Liquified Natural Gas • Why? • Reduces volume by more than 600 times (600 tankers instead of 1 LNG tanker) • Where? • Generally from areas with large discoveries: Algeria, Indonesia, Malaysia, Nigeria, Qatar, and Trinidad • Shipped to Elba Island near Savannah

  21. Liquified Natural Gas • Elba Island serves Eastern U.S., esp. Southeast • First LNG facility in U.S. to accommodate two tankers

  22. *in-service in mid-2010 *approximately 190 miles of 42-inch and 36-inch diameter, natural gas pipeline. *compressor station will be constructed later, to increase capacity in 2012

  23. Renewable energy options in S.C. Biomass-to-Energy Wood wastes Switchgrass Landfill gas Animal and human waste Wind Offshore Small-scale, land-based Solar Small-scale hydro Hydrogen

  24. Landfill gas • Currently, landfill gas is one of most successful forms of renewable energy in South Carolina. • Santee Cooper now has 17.1 MW at four sites; projects 42 MW in the future. • BMW utilizes landfill gas to produce the equivalent of 4.8 MW of electricity. • Enoree Landfill in Greenville County is generating 3.2 MW of electricity which is being sold to Duke Energy. • Kimberly-Clark constructed 3 MW-equivalent landfill gas project in Aiken Co. • FujiFilm starting project in Greenwood. • Another 75 MW of energy may be possible.

  25. Future of renewable energy • Attractive state incentives exist for biomass, but more needs to be done to encourage solar for businesses • Biomass such as wood waste, agricultural products and by-products, and landfill gas most viable renewable options right now • Solar, offshore wind, tidal and wave action are potentially abundant sources of energy in near future

  26. Energy for transportation • 13thin the nation in per capita motor fuel consumption. • In 2007, we used 3.2 billiongallons of motor fuel, costing $8.7 billion

  27. Growth rate of oil consumption, 1990-2005 • United States – 22% • World – 25% • South Carolina – 31%

  28. Alternative transportation fuels Compressed natural gas (CNG) Propane Hydrogen The Central Midlands Regional Transit Authority (CMRTA) operates six natural gas vehicles which currently refuel on Flora Street in Columbia. 83 other vehicles in SC also run on CNG. Columbia will soon be getting a hydrogen fuel-cell powered bus.

  29. Advantages Nearly 87% of U.S. natural gas used is domestically produced 60-90% less smog-producing pollutants 30-40% less greenhouse gas emissions Less expensive than gasoline Disadvantages Natural Gas-Powered Vehicles • Limited vehicle availability • Less readily available than gasoline & diesel • Fewer miles on a tank of fuel

  30. Natural Gas-Powered Vehicles • Dual Fueled vehicles – Require two separate fueling systems, take up cargo space • Dedicated vehicles – Honda GX CNG is the only model available now • Mileage 24/36 28 mpg equivalent combined • Retrofits possible

  31. CNG and Hydrogen • Natural gas is principle source of hydrogen for the foreseeable future • CNG fueling stations likely will be the pathway to the H2 fuel infrastructure in the future • Many equipment manufacturers are the same for CNG and Hydrogen vehicle systems and fueling • Compression: CNG & C-H2 • Liquefaction: LNG & L-H2 • Biogas is a renewable source of H2

  32. Biofuels Ethanol (E85, substitute for gasoline) & Biodiesel (B20, substitute for diesel) Reduce air pollution Create jobs in South Carolina Save money Decrease dependence on foreign oil Expansion of biofuels depends on development of feedstocks that are not used for food Arundo donax (Giant Reed) may be a useful bioenergy crop to produce cellulosic ethanol and/or energy.

  33. Ethanol and biodiesel feedstocks • Ethanol is made from: • Corn • Sugarcane, barley, sweet potatoes, etc. • Cellulose (wood chips, switchgrass, etc.) • Biodiesel is made from: • Soy oil • Canola oil • Animal fats • Waste cooking oil • Jatropha seeds • Chinese tallow tree • Algae
