Glycerin Powers into the Propulsion Picture

Maine Maritime Academy Receives a $1.4 Million U.S. DOT Research Grant to Develop a Marine Engine Testing and Emissions Laboratory. The Marine Engine Testing and Emissions Laboratory (METEL) at Maine Maritime Academy (MMA) is working on several initiatives to implement viable emissions reduction technologies for the marine industry. Funded by a $2.8 million grant from the U.S. Department of Transportation, the METEL laboratory was developed to address environmental sustainability needs in transportation. Working with a Maine startup company, Sea Change Group LLC (SCG), the METEL team is helping to develop and implement a fuel that combines glycerin with diesel fuel to lower both operating cost and emissions for marine diesel engines.

EPA to Move Forward with Domestic Emissions Standards

With the International Maritime Organization's (IMO) adoption of new emissions standards for large diesel ships and their fuels, EPA can now move forward with a domestic rulemaking action under the Clean Air Act. When fully implemented, this will help reduce harmful emissions by 80 percent or more from large diesel ships, including those that are foreign-flagged operating in U.S. waters. As emissions decline from other transportation sources, ship emissions will become a larger part of the nation's pollution inventory. In 2001, oceangoing vessels contributed nearly six percent of nitrogen oxide (NOx), more than 10 percent of particulate matter (PM), and about 40 percent of sulfur dioxide (SOx) to the nation's air pollution from mobile sources.
