This is the first time I've actually been able to write about something on AutoblogGreen that is happening right in my hometown. I see TARTA buses every day of my life, which makes sense because TARTA stands for Toledo Area Regional Transit Authority. According to their website, TARTA is running tests using low-sulfur diesel fuels and B20 biodiesel blends in their standard buses. Additionally, a system developed by H2 Engine Systems is being tested which injects a small amount of hydrogen into the air intake of a bus running B20. According to this article, drivers can feel the difference in performance when the hydrogen is being pumped in and when it's not. On a side note, isn't it kind of funny to think of a bus lapping a test track at relatively high speed? Anyway, the city has also installed a biodiesel filling station near where the buses are kept and the University of Toledo is assisting with the testing. I'll be sure to be on the lookout for the funny-colored buses running around town.
