(Undated) -- Federal officials are moving ahead with plans to promote the shipment of goods by zero-emission trucks up and down the West Coast. Authorities say the U.S. Department of Transportation is giving Washington, Oregon and California 102-million dollars to create a network of charging and fueling stations to power battery and hydrogen fuel-cell semi-trucks traversing the three states. Officials say major hubs would be built in San Diego, Los Angeles, San Francisco, Portland and Seattle.
