Well how about CNG for home use, anything other than propane.
The technical issues of CNG are far easier. I don’t know the economics would work out better than propane.
There is significant expense in providing the high pressure tanks at sufficient volume. It might become more economical with more CNG vehicle fueling stations as more providers of CNG move into an area.
In my opinion, it is one more reason to promote LNG exports, it will actually bring more propane, ethane and the like onto the domestic supply market.
