Passengers traveling through San Francisco International Airport will be doing their bit for the environment thanks to a new agreement to adopt green shuttle buses.

The airport has entered into a partnership with Hythane Company and BAF Technologies and netted a grant of almost $500,000 to operate 14 shuttles running on hythane, a blend of hydrogen and natural gas.

Awarded by the Bay Area Air Quality Management District, the grant is designed to encourage environmentally-friendly technology and should see a dramatic drop in emissions.

With parking lot, hotel and airline crew shuttles all set to run off the gas, San Francisco Airport should be a cleaner and greener place.

Nitrous oxides should fall by 56 percent while current levels of carbon dioxide should fall by 40 percent, with the project designed to demonstrate the potential for similar schemes elsewhere.

Roger Marmaro, President of Hythane, said the shuttles were an example of the innovative thinking needed “to move clean transportation projects forward”.

U.S. airports have long been leaders in green technology. Los Angeles International Airport (LAX) is one of the largest test sites for emission-free fuel cell vehicles in the country.

Employees at the airport use a range of fuel cell cars for general transport purposes. LAX boasts more than 400 green vehicles in its fleet.
