Small-scale LNG: A reality today may be a game-changer for tomorrow

As an energy source, LNG is gaining ground compared to coal and oil, not only because it is cheaper, but also as a way to meet emissions reduction commitments by governments. As a transportation fuel, natural gas emits approximately 20%–30% less greenhouse gas than diesel or gasoline, and it emits 50% less greenhouse gas than coal when generating electricity (Fig. 1).

Global LNG consumption in 2017 was estimated at 285 MM
