Comparison of Energy Efficiency and Carbon Dioxide Emissions of Gas Turbine Cogeneration with Steam Absorption Chillers versus Conventional Chilled Water Generation

Abstract

Malaysia government committed to reduce greenhouse gas emission by 45{%} by 2030. This target was set with 35{%} on unconditional basis and 10{%} on conditional basis upon receipt of climate finance funding, technology transfer and capacity building developed countries. This paper demonstrate how cogeneration district cooling power plant helped to mitigate greenhouse gas emission by comparing fuel efficiency and carbon dioxide emissions of the cogeneration district cooling plant and a conventional electrical chiller plant which electricity was imported from the power grid. The GT Pro simulation is used to estimate the efficiency and the carbon dioxide emissions from the power plant. Results and analyses indicate that the cogeneration district cooling plant consumed 30.47{%} less primary energy and emit 44.43{%} less of carbon dioxide as compared to the conventional power plant. Hence, the adoption of cogeneration district cooling plant will definitely help the nation goal to reduce greenhouse emission intensity by 35{%} to 45{%} by 2030.
