Buses are ideal for natgas. They are always running and mostly in urban areas where their green attributes are welcome or mandated.
I believe that the Boston area has a large fleet of natgas buses. I recall that they formerly had pressure vessels for compressed natgas. I think they are now LNG fueled with smaller tanks. They don't vent to atmosphere because the vapor is consumed by the engine faster than it is created: even on hot summer days. I'll bet that some of the air conditioning energy comes from the LNG evaporator as well.
The LNG terminal that receives the shipments from Yemen is located next to a large bus maintenance facility. Only a small percentage of the imported LNG is used to fill buses. The rest is vaporized and supplies the pipelines.
30 miles away in my town of Tewksbury, MA is another CNG and LNG fuel station. The Lowell Regional Transportation Authority fuels their fleet there. It wouldn't surprise me if there were more than 100 of these stations around the country, many of them in CA.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
