98% purity is fine. This will not flow through regen passages so not
terribly concerned about impurities coking walls. Our back up plan is to
liquify it from CNG using LN2, but I would rather not.

My information is likely out of date but when I last looked the only pure
liquid methane plant in the country was across the street from Beale AFB in
Sacramento.
LNG is about 98% methane in most cases but it is as I recall typically
stored under self-pressurization at ambient temperatures, thus requiring
cooling for rocket use.

Seconding this. MIT Rocket Team is looking for anyone who would sell us
liquid methane, about 50L. We have a engine but we can't test it until we
find the methane...

All,
Does anyone have a source for liquid methane in Southern California?
Specifically a 75L+ dewar/tank delivered. I have found several LNG fueling
stations nearby, but they require a DOT certified tank and a search for DOT
certified tanks shows them costing $6K and up!
