One idea I've thought of is to convert a N2 cryogenic tank to LNG. I found one other thread on another forum on this topic but unfortunately it didn't have much information. They said it should work. I would still need to the correct fittings to refuel but those are available.
What other modifications would be required to convert a N2 tank to LNG? Is it technically feasible? Practical?
I appreciate any input on this topic. This is not my area of expertise yet, I am learning more about these LNG systems there is just not as much information readily available like for CNG systems. In order to carry out this experiment I need LNG but my budget is restricted to less than $10k so I'm trying to find a solution.
Thank you for looking!
