You take the high(drogen) road and Oklahoma'll take the CNG road. That's the situation in the Sooner State now that Governor Brad Henry signed the Oklahoma Energy Security Act, which tries to make the state less dependent on foreign oil, into law last week. The new law declares that 15 percent of the state's electricity has to come from renewable energy sources by 2015 and, more germane to our car-centered blog here, it "spells out goals to have CNG fueling stations located along the Interstate highway system in the states."

Specifically, Oklahoma will attempt to install a public compressed natural gas fueling station every 100 miles along all of the interstate highways in Oklahoma by 2015. By 2025, this number of stations will increase to one every 50 miles. The state's Department of Central Services is in charge of the program, and it's expected that public-private partnerships will be used to get the stations up and running. In April, Oklahoma became the fourth state where the only CNG-powered passenger car for private use in the U.S. went on sale. Thanks to Steve G. for the tip!
