Veolia Transportation, a major public transporation manager in the U.S., has announced it is converting some 300 taxis to run on propane autogas. Earlier this spring, the company organized a big to-do that included Baltimore Mayor Stephanie Rawlings-Blake and U.S. Sen. Ben Hardin.

“MotorWeek,” a long-running PBS show that features automotive and alternative transportation fuel news from accross the country, was able to film part of the event. Autogas for America Founder and Alliance AutoGas President Stuart Weidie was also on hand, and optimistic about the future of the industry. “What we’re seeing is exponential growth in terms of the adoption of propane autogas in fleets. They realize that it’s got these positive benefits,” he said.
