Just like the fracking revolution happened while the fedgov was out pimping batteries, windmills, and solar, I think CNG will find it way into vehicles quite nicely.
Locomotives are a perfect application, and I suspect they will be a big user eventually. Plug in a gas tank car behind the engine and away you go.
Great point on Wash state and LNG availability. (The network is east - west at first, but being built quickly.)
Look at HDMI technology for cold weather. It is a high pressure system for heavy duty engines. Westport Innovations is the company that has that technology. I think it is available on many trucks. This technology produces more power than spark ignited nat gas engines, which are good for medium duty.
There are lots of advances in natgas infrastructure and technology.
I think there is a chance that the energy density is different from what you post. Are you sure you are quoting LNG and not CNG?
Regards,
I just checked LNG has a little more than half the energy density of diesel...
You are absolutely correct, that will impact range.
(unless more space is used for tanks)
