Countermeasures for Environmental Issuesat Receiving Terminals
1. Reducing CO2 Emissions in the LNG re-gasificationprocess- Using ORV for the base load and SCV for peak shaving
2. Using cryogenic energy- Liquefied nitrogen and oxygen extracted from liquefaction and
separation of air, cold storage warehouses, cryogenic powerproduction, etc.
3. Reducing the environmental burden from LNG tankers- 75% reduction in SOx emissions of LNG tankers at berth using
BOG

Addressing global environmental issuesas energy suppliers will be essential to
further expand the LNG market.
