Plus you mention having larger cars, although possible, larger = heavier = uses more fuel.
Regarding compression, im running 11:1 on my car. Almost as high as you can go with 95RON fuel. i could go a bit further if i fill my gasoline tank with 98RON only.
2 of the points you make, depend on having a car that runs 100% on CNG, and although possible, it would limit the car quite a bit.
Down here we have a pretty decent network of CNG stations all over the country, you can drive to almost every major city without needing to use gasoline.
No way you are pulling 200 miles out of that puny tank. I have a 60liter tank, charged at 200bar, running on my 2liter engine, i can barely pull 85miles at 100kmh (60mph).
I'd love to get one of those home charging units though.
Dont get me wrong, CNG is great, but range aint one of it strongpoints.
@Coyote27981 My comparison was to electricity not to gasoline. and yes it does have greater range than electricity because you can refuel at cng fill station in the same time that it takes to fill w/gasoline. With electric you need to wait hours. Highly impractical for a long trip. However for the sake of comparison of cng vs gasoline the problem is the size of your tank NOT the CNG fuel source. The simple solution is to increase your tanks or capacity.
@ashonteibilly Wasnt talking about your post mate, just about the video.
BTW, tank capacity is not solved THAT easily, specially on small cars. i got my tank on the trunk, and ive lost about 60% of its total space. I mean, its great to be able to drive around cheap and clean, but cars have trunks for a good reason :P
I would love to have one of those home refill units, since i hardly use a full tank on my daily conmute. so having it full every morning would be great.
@Coyote27981 Third if you design the vehicle slightly larger, you can still have adequate trunk space. Most petrol powered cars place the gasoline tank under the trunk and/or under the rear passenger seat. A slight height adjustment(increase) in the vehicle design means you can place a(n) additional tank(s) where the gasoline tank would normally reside. If you design from the ground up specifically as a CNG vehicle you really don't have to lose much trunk space.
@ashonteibilly The problem is that current cng vehicle options are just vehicles that were designed on a gasoline model platforms. Actually tank/space problems can be solved easily w/ currently available technology in 3 ways. 1) Instead of using engines designed for gasoline, use diesel type engines w/ higher compression. This increases fuel economy >20%. 2) Design tanks that can hold higher PSI (i.e 4200 instead of 3600) this means more fuel in a tank only millimeters larger 3(see next post).
@heartlessvietboy It's just like any other gas appliance in your home. Even less dangerous if the garage is detached since that is not in your living quarters. Unless you have a basement garage, a typical garage is less air tight then your home and a vented garage with standard peak louvre vents also allows for the gas to escape and reduces pooling since natural gas is lighter that air. As for the electricity many gas furnaces use an electric ignition pilot light with a good safety record.
@heartlessvietboy Where's the electricity going to come from? Since the fastest growing segment of new electrical power generation is from natural gas fueled power stations, then I may as well just use CNG. Steel and carbon fiber tanks are cheaper than expensive batteries. I need to drive when it's cloudy and there is no wind, so I'm not relying on renewables, either .Electricity is impractical for larger vehicles as it can't supply the energy needed for long distance hauling or towing.
Electricity comes from Three-Magnet Generators aligned back to back. It's exactly how you use household magnets. When you hold 2 together they began to attract. When they attract, you add a third magnet to the center it begins to spin. When it spins it creates electricity.
@heartlessvietboy Magnets do not just continue turn by themselves & generate electricity just by adding a 3rd magnet. The magnets are attached to a spindle as part of turbine set up. The turbine needs an energy source to spin the magnets and generate the electricity. No energy in=no electricity out. In natural gas power stations the turbine turns typically from pressurized steam created by heat released from the combustion of gas. So in the end we are back to natural gas.

Having the home fueling option negates ANY savings by using CNG! $40 - $80 a month???? Plus installation? WOW!
Might as well stick with gasoline until we have more fueling stations.
ewsews.com has a conversion kit you can do yourself.

making a fuel cell would be such a better use of natural gas(i'm i believe at that point you'd have other options besides just natural gas)

But thats as long as you stay on the highways.

@summt5697 You have to increase the pressure to about 2000 psi .. it's about 4-800psi from the line.. so you need a compressor a high psi compressor.

How dangerous can it be for people to be using natural gas in their Garage? Let alone equipping it with electricity.

Love Honda's home Hydrogen station also.
Come on fuel cell vehicles !
