Liquefied natural gas — methane chilled until it can be shipped as a liquid — has been pitched in some quarters as a cleaner intermediate step on the way to renewable electricity. We disagree. In Hawaii’s specific context, building out LNG import terminals, storage, and regasification infrastructure would be both economically wasteful and environmentally counterproductive.
The lock-in problem
LNG infrastructure has a thirty- to forty-year operational lifespan. Hawaii’s renewable mandate hits in 2045. The math does not work: any LNG plant built today would either become a stranded asset within twenty years, or it would be used to justify pushing the renewable deadline back. Both outcomes are bad.
The methane footprint
Methane is roughly 80 times more potent than carbon dioxide as a greenhouse gas over a 20-year horizon. Even small leaks at extraction, liquefaction, shipping, and regasification stages erode the alleged climate benefit relative to the heavy fuel oil it would replace.
Better alternatives exist
Solar plus battery storage is now consistently cheaper than new fossil generation in Hawaii’s procurement auctions. Demand response, energy efficiency, and offshore wind round out the toolkit. We do not need a new bridge — we need to keep building the road we already started.
