  • Technologies to reduce carbon emissions
    • Carbon capture and storage
      • Capturing  CO2 released by FF's and burying it deep underground.
        • Expensive due to process and technology.
        • the carbon could potentially leak slowly up.
      • This must be given high priority as we know FF's will continuously be used.
    • Hydrogen fuel cells
      • Combine hydrogen and oxygen produce energy, heat and water. will always supply energy as long as oxygen is supplied and does not need to be recharged.
      • They are reliable for supplying energy to buildings and transport.
      • Challenge is finding a cheap and easy source of H - it does not occur naturally as a gas. (always combined with other elements).
      • Can offer a real prospect of reducing carbon emissions.
    • Using these would promise much less disturbance to the carbon cycle.
