CO2 reduction using LNG cold energy.

Author(s) : IKEDA M.

Summary

The Osaka Gas Himeji LNG Terminal began operation in 1984 as a natural gas processing and supply base. In 2004, the terminal began to commercially operate a gas turbine combined cycle power generating unit (GTCC) with a rated output of 52 450 kW, thus launching a power retail business aimed at transforming the terminal into a multi-energy supply base. Himeji LNG Terminal boasts some 20 years of experience in utilizing LNG cold energy using natural gas processing/supply facilities and power generating facilities. By generating electric power without discharging CO2, the terminal has been helping to reduce energy consumption and environmental impact. In the period from when the terminal commenced operation to 2005, the cumulative amount of LNG applied to cold energy utilization reached approximately 60% of the total amount of LNG vaporized at the terminal. The cold energy obtained from this LNG was used to supply 53% of the electricity consumed at the terminal. As a result, the amount of CO2 emissions reduced by utilizing LNG cold energy reached approximately 264 000 t CO2. This paper introduces the outline of the following cold energy utilization facilities at Himeji LNG Terminal, such as the amount of utilized cold energy, efforts to promote cold energy utilization, the amount of power consumption reduced by utilizing cold energy, and the amount of CO2 reduction.
