You've convinced me. (I was surprised to learn, though, that there's a public CNG station less than a mile from my house.) Makes me wonder why a large chunk of the buses in Boston use CNG. Hopefully they shift over to EV as battery tech matures.I wrote up an analysis of cng cars on my blog.
They are inferior to EVs.
If you have a fleet and need to build infrastructure you are much better off building EV infrastructure.

make that 12.8 kWh.You can buy a home CNG filling unit that will cost you about $6000 installed. It can refill your car in about 16 hours. But it uses 800watts to do that, so in 16 hours it would consume 12.8kW of electricity.
Would be easier to understand if you state the miles per year and your home tariff for electricity and natural gas.If you refill exclusively at home, you will spend $932 per year on fuel ( $857 on the CNG and $75 on the electricity to run the compressor! ).
make that 34 kWh.The Leaf is rated at 34kW per 100 miles, so $448 per year in electricity.

Perhaps it is too much to ask people go hybrid and then even use an alternative to conventional gasoline. Or car manufacturers think so.I still don't understand why we don't see diesel or CNG hybrids... Basically only gas.
Adding a hybrid drivetrain to a CNG car should increase its' range and efficiency just like it does for gasoline vehicles.

But diesels are extremely efficient in a narrow rpm range so I would think they would be perfect for the type of hybrid where the engine is acting purely as a generator and not driving the wheels (like on a Prius). Stopping and starting a diesel and running it cold is very expensive efficiency-wise but once you get it running and warmed up it uses very little fuel.Diesels are expensive, hybrids are expensive, diesel-hybrids are expensive squared.
