FULL FUEL CYCLE EMISSIONS OF GREENHOUSE GASES FROM COAL FIRED POWER STATIONS

摘要

Coal-fired power stations produce around 30% of Australia’s total Greenhouse gas (GHG) emissions (Environs Australia, 2001 & ABS, 1998). These emissions arise from the various stages of mining, preparation, transportation, utilisation and waste disposal in the full fuel cycle. All these stages involve emissions relating to (1) the construction of infrastructure and facilities and (2) operation of the facilities. This paper looks at various scenarios for Australia’s future power generation systems and assesses their impact on GHG emissions. These scenarios include cogeneration and co-firing options, as well as integration with renewable energy systems based on solar, wind and biomass.
