Content Inside: West Coast Diesel Emissions Reduction Collaborative Bio-diesel in Small Watercraft
Working with leaders from government, the private sector, and environmental groups the West Coast Diesel Emissions Reduction Collaborative (Collaborative) encourages projects that reduce diesel emissions. The Collaborative seeks to fund projects that are regional in scope, leverage other funds, result in real measurable reductions/results, and create momentum for future reductions. This document describes a potential Collaborative project in the Marine Sector: Bio-diesel in Small Watercraft. Project at a Glance Projected total emissions reductions of NOx, PM2.5, Sulfur, and/or GHG is 30 percent over the life of the project. Project will benefit entire air shed of greater Puget Sound region, with surrounding population of approximately 2 million. Project will ultimately reduce emissions from Navy and other diesel powered marine vessels operating in the waterways of greater Puget Sound. Projected direct fuel savings of 10 percent Bio-diesel may not be classified as a hazardous material resulting in storage and transportation requirements having additional cost savings. Problem Statement Sustainable operation of diesel powered marine vessels on Puget Sound waterways is essential to meeting the mission requirements of the U.S. Navy and other government and private maritime organizations. Increasingly, these organizations are turning to alternative fuels such as bio-diesel to operate with lower engine emissions of particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), hydrocarbons (HC), and sulfur oxides (SOx). Marine engines comprise some of the least regulated sources of diesel emissions in the U.S. Global trade and port activity are increasing, while controls on land-based air emissions are tightening, making the share of total air emissions represented by the marine industry a growing target for regulation. Bio-diesel is the first and only alternative fuel to have a complete evaluation of emission results and potential health effects submitted to the U.S. Environmental Protection Agency (EPA) under the Clean Air Act Section 211(b). Bio-diesel is a nontoxic and biodegradable fuel made from organic fats and oils. Bio-diesel can serve as a replacement or enhancer for petroleum diesel. Bio-diesel can be blended with petroleum diesel when used in existing diesel engines with little or no modification to the engine. In blends as low as 20 percent volume (B20) bio-diesel has been shown to substantially reduce particulate and other emission pollutants and improves engine wear. Sulfur emissions are essentially eliminated with pure bio-diesel, which contains no sulfur. However, the absence of detailed government specifications and quality assurance procedures for military grade Bio-diesel hamper efforts for expanding it use. Proposed Actions Navy Region Northwest (NRNW) is initiating the use of bio-diesel in selected diesel engines. NRNW intends to evaluate bio-diesel in several applications including small watercraft (i.e. tug boats), power
