Forget cooking with gas -- Clean Energy Fuels is driving with gas. Natural gas, that is. The company owns and/or supplies about 260 natural gas fueling stations across the US and Canada. These enable Clean Energy's 480 fleet customers to tank up their more than 25,200 fleet vehicles with compressed natural gas (CNG) or liquefied natural gas (LNG). Clean Energy also helps customers buy natural gas vehicles and obtain government incentives. The company buys CNG from local utilities and produces LNG at its two plants (in California and Texas) with a combined capacity of 60 million gallons a year.
