Exactly. These days there are several companies. In fact a very well-known Canadian company, now owned by a U.S. company but headquartered in Chilliwack, British Columbia, called IMW Industries, is one of the world leaders in natural gas refuelling stations. They provide anything from a small-scale refuelling station that has one receptacle all the way up to these large-scale, multi-point refuelling stations for big waste fleets or transit fleets. They can be installed on a pipeline, just like the one for residential.
