You need to learn more. The NIMBYs and environMENTALists have put out a lot of false information, spreading a myth of false dangers.
LNG won’t ever burn, let alone explode. It has to be vaporized first to methane gas then mixed with air down to a 5~15% concentration. By the time that has happened during a leak, the vapor, which is much lighter than air, has risen up and away from the tanks.
Secondly, there is not LNG Inports or Exports in Houston. That is down at Freeport.
OK I am full of crap on this subject. It may have been an ammo ship that went up in the northeast. I know methane used to work in the coal mines. Also knew that the ratio had to be reached to explode it. But with the correct ignition source are you saying it can not ignite? First explosion releases the gas, delayed second explosion ignites the gas after the air fuel ratio is reached. Not possible?
