LNG – Liquefied Natural Gas
• Natural gas is cheaper and cleaner (> 10KWh/m3). • Minus 161 0C it condenses into colorless, odorless, non-toxic, non-
corrosive and non-carcinogenic liquid. • Occupies only 1/600 of the volume of its gaseous state • Natural gas is measured in MMBtu3. • The first LNG plant was built in West Virginia in 1912.
HUGE Environmental Benefit
In comparison with heavy fuel oil, natural gas has a much smaller impact on the climate, the environment and health.
LNG supply chain consists of
1. exploration, 2. production, 3. liquefaction, 4. shipping and storage together with regasification.
• The number of LNG importing countries has tripled
over the past 15 years.
• Recently, a total of 7 new regasification terminals were
completed worldwide.
• Three of these were onshore terminals: • in Japan (Hachinohe and Shin-Sendai) and Indonesia (Arun, which was
converted from a decommissioned liquefaction plant).
• The other four were FSRUs completed in new LNG markets: • in Egypt (Ain Sokhna BW and Ain Sokhna Hoegh), Jordan (Aqaba)
and Pakistan (Engro).
