Transcript

  • 1. GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 2. Why Geothermal? Clean, renewable, efficient energy obtained from beneath the earth’s surface. GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 3. Why Geothermal?
    • Cost Benefits:
    • 30-70% annual energy savings
    • Lower operating cost
    • Re-use of waste heat
    • Reduced cost of emissions control
    • Rebates, grants, tax incentives
    • Environmental Benefits:
    • Use of renewable energy source
    • One of the most efficient heating and cooling solutions available
    • No reliance on fossil fuels
    • Eliminates CO health threats
    • Reduced CO2 emissions
    GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 4. Types of geothermal well systems Closed Loop Open Loop / Standing Column Well Direct Exchange / Open Diffusion GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 5. Closed Loop
      • Most common system
      • Wells typically installed 400’ to 500’ deep
      • Average tonnage = 150ft/ton
      • Contains environmentally safe water-antifreeze mix
      • Very little maintenance once installed
      • Well system not affected by environmental conditions, i.e. contamination
      • Wells not generally affected local geological conditions.
      • State & federal tax credits and/or grants typically apply.
    • Examples of Closed Loop Systems:
      • King Point Maritime Academy, NY
      • Internal Revenue Service buildings, Andover, MA
      • Many military bases through the U.S.
    GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 6. Open Loop / Standing Column Well
      • Usually installed where space is limited
      • Not applicable at all sites due to geological conditions (need bedrock)
      • Average tonnage = 100ft/ton (greater with bleed, approx. 10% gain)
      • More maintenance concerns – submersible pumps, water quality in wells, etc.
      • State & federal tax credits and/or grants typically apply.
    • Examples:
        • Harvard University, MA
        • Yale University, CT
        • Trinity Church, Boston, MA
    GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 7. Direct Exchange / Open Diffusion GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 8. Direct Exchange / Open Diffusion 1) A deep production well is drilled to an underground heat source 2) The pressurized steam or hot water is released and piped to a power plant, where its force turns a turbine
    • Some advantages of geothermal energy are no fossil fuel emissions and no nitrogen oxide emissions on the property.
    • Examples:
      • Nesjevellir Geothermal Plant, Iceland
      • Geysers Geothermal Plant, Sonoma and Lake Counties, CA
      • Steamboat Spring, Reno, NV
    GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 9. Conceptual Closed Loop Geothermal Design GS Environmental and Groundwater Associates GSEGA H ARRIS M ILLER M ILLER & H ANSON INC.
  • 10. Benefits of using geothermal at airports
    • Reduce / eliminate emissions
      • Carbon Monoxide
      • Nitrogen Oxides
      • Sulfuric Oxides
      • Volatile organic compounds and hydrocarbons
    • Quick return on investment
      • Airports typically operate 24/7
      • Large open areas help reduce number of heat pump units
      • Typical R.O.I. = 5-10 years
    • Heat runways / taxiways
      • Hydronic radiant heating – hot water circulates through a series of pipes within the ground, pavement, concrete, etc.
    • Airports have large open areas that can support buried geothermal systems
