Conversion kits are cheap, tanks aren't... I sold my CNG powered Tempo when I discovered that my existing tank was (supposedly) a time bomb and a like replacement tank was $4000 ... or a bargain basement one was $1290 for 2GGE.

Whatever is cheapest is right.

The country we live in believes that the KeystoneXL pipeline is about jobs and energy indepedence . . not the fact that the majors have enlarged/modified the refineries at Port Arthur to sell the resulting product overseas.

Life in Nigeria and Ecuador = what it will be like here socially & politically as time goes further on. It ain't gonna be pretty. The cost won't be borne by producers nor offset in other ways.

We drill till we die, baby. The U.S. ain't exempt from history or larger trends.
Today's low cost is meaningless long-term. It's access and affordabilily. Do what's cheapest.

Good Grief.
Two 120L cryogenic LNG tanks (stainless steel, double wall with high vacuum insulation to keep the liquid fuel below -260F for extended periods of time) - $15K each. Hydraulic powered LNG pumps - draws LNG from tanks, pressurizes it to 4000-4500 psi and evaporates it using engine coolant for heat - $5K each. CNG accumulator (carbon fiber) - $8K. Six fancy fuel injectors - $1200 each, lots and lots of R&D - priceless. Oops, this turned into a plug for Mastercard.

It's a factory option for Kenworth and Peterbilt right now, more OEMs to come.

In fleet that basically runs 24-7, $80K per truck will be absorbed into fuel savings relatively quickly. Plus, they get to play the green card to attract customers and get government grants.
