A new study from Purdue University shows that buses that have been running 10 percent biodiesel are reducing pollution without any loss of fuel economy.
This press release from the school says the report, prepared by Gregory Shaver, an assistant professor of mechanical engineering, doctoral student Dave Snyder and undergraduate Chris Satkoski, found that upping that mix to 20 percent would have even greater results:
The university’s Technical Assistance Program at the Purdue Research Park arranged for the engineers to prepare the study for IndyGo Public Transportation Corp., which provides mass transit in Indianapolis. The report was presented to Indianapolis Mayor Greg Ballard earlier this month at Purdue’s Ray W. Herrick Laboratories in a visit organized by the university’s Energy Center.
The report compared bus operations in April 2006 and April 2007 to determine the impact of switching from standard diesel fuel, referred to as B0, to B10, which contains 10 percent biodiesel. IndyGo switched its entire fleet to B10 in 2007.
“In our assessment, we would recommend going to B20,” Shaver said. “We also saw a significant benefit to using the diesel-electric hybrid buses, so we would recommend increasing the number of hybrids in the fleet. The best bang for your buck might be running B20 in hybrid buses, depending on the initial cost of hybrids compared to standard buses.”
The researchers say switching to B20 could save Indianapolis 360,000 gallons a year, while significantly reducing its carbon footprint.


The National Biodiesel Board has teamed up with two companies to launch a pilot program to show how much lower emissions are using biodiesel. NBB, along with Chicago-based Indigenous Energy, LLC, developers of emissions tracking systems, and Los Angeles-based States Logistics, a fleet and logistics company using clean technology, to put together the six-month over-the-road test.
Senator Saxby Chambliss of Georgia is proud that his home state is playing a role in the production of alternative, domestic fuels.
“Continuing to develop renewable energy is a key component of President Bush’s strategy to reduce America’s dependence on foreign oil,” Dorr said. “This meeting is an opportunity for business owners, citizens and agricultural producers to discuss the best ways to harness the untapped renewable energy resources in rural areas.”
Iowa-based Renewable Energy Group has announced it has the technology to produce biodiesel from algae on a commercial scale.
Lake Erie Biofuels, the Pennsylvania biodiesel maker with a 45-million gallon a year biodiesel refinery on the shores of Lake Erie (so it’s not just a clever title) is reportedly considering building a pipeline from its plant to the ports of Erie, PA… but company officials aren’t saying much about the project.

This December, the Federal Trade Commission’s new rules on labeling of biodiesel pumps kicks in. Basically, pumps that dispense greater-than-5-percent biodiesel blends will have to have a label indicating that pump’s blend.
