Westport, 12% owned by T. Boone Pickens, only trades in Toronto right now under symbol WPT. But the company, which makes fuel systems for commercial vehicles that allows them to run on liquefied or compressed natural gas, is involved with a project at the port of Long Beach, Calif., that will convert the older trucks being used there to newer, cleaner models.
Clean Energy is also part of the Long Beach initiative, but its business is in turning nat gas into a usable fuel. The company has its own liquefied natural gas plant, is building another, and has 175 fueling stations in the U.S. and Canada, including one at the Long Beach port. There are plans to build two more in the area.
