What About Venting?

Question: I am concerned about too much pressure building up in the fuel tanks at your LNG plant, and you having to vent that gas into the air. How often will that happen?

Answer: Thanks for the question. As LNG warms up, it very slowly (over several months) changes from a liquid to a gas. This is called “boil off” and it increases pressure in the fuel tank. Typically if pressure gets to a certain point, the gas must be released (vented) into the air. However at our LNG facility, the boil off gas will instead be piped to our near-by back-up diesel plant and used to warm the building and the engines. That means we won’t need to do any venting.
