Connie and Travis Jones pose with their 2003 natural gas powered Honda Civic and natural gas home refueling station located on the garage wall of their home in Chandler, Arizona, October 3, 2013.Home refueling units, which tap into a house natural gas main and compress the fuel so it can fill a vehicle tank overnight, have been available for years. With natural gas at $1.40 per equivalent gallon, it costs the Joneses $30 to drive their Honda Civic GX 1,200 miles (1,930 km) each month, about $130 less than an average gasoline car covering the same distance.

Natural gas powered cars

October 4, 2013

Home refueling units, which tap into a house natural gas main and compress the fuel so it can fill a vehicle tank overnight, have been available for years.



But even though the fuel is cheap and units have to meet safety standards like other household appliances, home refilling is uncommon in the United States, held back by the upfront expense of buying and installing new units, and a lack of natural gas cars. The cars themselves generally cost about $10,000 more than comparable conventional vehicles. (Reuters)
