I have a diesel truck. I want to use CNG as a part of fuel. Using 50% CNG 50% diesel I will need about 2 GGE to drive around. I am thinking about a AC compressor boosting pressure from 2psi (my service pressure) to 150-200 psi. Then use a hydraulic cylinder to boost pressure to 1200 Psi. I don't need 3000 Psi. 1200 Psi will give me 2GGE.

Now my options to buy York auto AC compressor and couple it with electric motor (explosion proof) OR 2 ton R22 AC Copeland sitting around....

York is a real beast but Copeland has electric motor and will make no noise...

AC compressor can easily deliver 200 Psi. Also all AC compressors spit oil. This oil will help to lubricate and seal hydraulic cylinder. I will need to add oil separator (high pressure like scuba...)

So this is one of my projects right now......
