Or even 'an LNG terminal'.
It does depend on the reader knowing what LNG stands for, but that would vary depending on your target audience.
Where I live it's well known, because we have extensive gas deposits (and oil to a lesser extent), and the various production industries are a major source of employment. I imagine it's noticeably less familiar in other regions of the US, as it's primarily used just as a storage and transportation method for natural gas.
Here, we're just starting to see the first talk of it eventually being publicly available as motor fuel.
