Clean Energy Fuels (CEF) signed a deal with General Electric (GE) to purchase its natural gas vehicle fueling assets in an effort to expand what it describes as “America’s Natural Gas Highway.”

CEF is owned on a 20.8 percent basis by T. Boone Pickens, energy magnate and owner of the hedge fund, BP Capital. Andrew Littlefair, President and CEO of CEF, described the deal as one of the “most significant milestones in Clean Energy’s history.”
