Stations to Operate 24/7 to Support Expanded Chicago Deployment of
Clean, Green, Cost-Efficient Natural Gas-Powered Taxis, Vans, Shuttles—

Chicago, Illinois (June 16, 2011) — Clean Energy Fuels Corp. (Nasdaq: CLNE), North America’s leading supplier of natural gas fuel for transportation, hosted a ceremony today to mark the opening of two public access compressed natural gas (CNG) fueling stations in Chicago. Part of a planned Chicagoland network, the new natural gas stations will support growing fleets of taxis, paratransit vehicles, service vans, refuse trucks and shuttle buses powered by clean, green, domestic natural gas.

Chicago’s Taxi Medallion Management (TMM) operates over 800 vehicles in Chicago. They currently have vehicles in both Yellow and Checker taxi affiliations. Michael Levine, the owner of TMM and chairman of both Taxi Affiliation Services LLC and American United Taxi Affiliation, Inc., entered into two 15-year contracts with Clean Energy to build and operate the two CNG fueling stations, and supply fuel to the initial TMM CNG fleet of up to 100 vehicles. Included are Ford Transit Connect and Chevy Impala taxis as well as MV-1 paratransit vehicles. In addition to serving the TMM fleet, the stations are open 24/7 for public access.

Located at 540 West Grenshaw Street and 3145 North Western Avenue, the CNG station sites were selected for their proximity to downtown Chicago’s business, hotel, shopping and financial districts.

Government officials and business leaders attended the June 16th reception and ribbon-cutting ceremony at the new Clean Energy West Grenshaw Street station site. Among speakers at the event were T. Boone Pickens, author of the “Pickens Plan” to enhance US energy security, and Michael Levine, Owner, TMM.

Mr. Pickens commented, “Our continuing dependence on OPEC oil is a critical threat to our economy and our national security. The only way to address that threat is to replace their more expensive, dirtier diesel/gasoline with cleaner and cheaper domestic fuels. There are several options, and domestic natural gas is one of them. If we don’t start using our abundant domestic supplies of natural gas for transportation, we are going to go down as the dumbest generation ever.”

TMM’s Levine said, “Taxi Medallion Management has always been committed to providing the best possible service to our drivers and to the community at large in Chicago. To that end we have updated our fleet of vehicles, we have added the latest technology to enhance the taxicab rider’s experience, and now we are taking the next step in metropolitan taxicab evolution, the deployment of alternative fuel vehicles. Our new CNG- powered fleet will drastically reduce the impact of rising fuel prices on our drivers. It will benefit the city by reducing carbon emissions, and it will help begin the process of reducing our nation’s dependency on foreign fuel sources.”

Supporting the local deployment of alternative-fueled cabs, the City of Chicago’s Department of Environment has implemented a Green Taxi program, which reimburses taxi companies that purchase vehicles powered by alternative fuels or hybrid vehicles. Chicago cab companies receive from $9,000 to $14,000 for purchasing a CNG car, and $2,000 for purchasing a hybrid car. The program operates on a first-come, first-serve basis and continues until December 31, 2011.

Delivering considerable fuel savings, often over $1.50 per gallon equivalent when compared to diesel or gasoline based on current market conditions, CNG fuel also produces up to 30% lower greenhouse gas emissions in light-duty vehicles and 23% percent lower emissions in medium to heavy-duty vehicle applications. U.S. Department of Energy reports estimate that 98% of the natural gas consumed in the U.S. is sourced in the U.S. and Canada.
