Alternative Fuels

The Objective of the Cleaner Fuels & Technologies Workgroup is to share information and seek funding for a variety of projects including: Cleaner Fuel Use, Engine Retrofitting and Fuel Reduction.

There are three primary approaches to reducing diesel emissions:

Cleaner Fuel Use

Heavy duty vehicles pollute the air we breathe because their fuel is, typically inherently dirty. A "cleaner fuel" is a cleaner-burning replacement for regular diesel fuel, whether it is a modified form of the same fuel or an outright alternative to diesel. Unlike retrofit devices, the use of cleaner fuels reduces harmful air pollutants before they are combusted in the engine.

The Collaborative is fuel neutral and supports "cleaner" forms of diesel fuel and alternatives to diesel fuel.

Engine Retrofit

Diesel engines retrofitted with after-treatment air pollution control devices can achieve considerable emissions reductions. Many of these devices significantly reduce emissions on stationary and mobile diesel engines. The Collaborative broadly defines diesel engine retrofits as engine replacements, repair, retrofit (after-treatment controls) or repower.

The term “retrofit” is most often used to describe exhaust aftertreatment devices. While exhaust aftertreatment technology represents a very promising category of solutions for in-use emissions reduction, it is only one of a number of options. In addition to cleaner fuel use and idle reduction technologies and practices, here are some other opportunities to reduce diesel emissions:

Fuel and Idle Reduction

Heavy duty vehicle/vessel idling provides heat or air conditioning inside the vehicle/vessel for driver/occupant(s’) comfort, keeps the engine and fuel warm during cool weather, and provides electrical power for onboard applications. While this can often best be accomplished simply through behavioral changes by the drivers, there are certainly relevant technologies to reduce idling-related air pollution:

West Coast Collaborative Medium & Heavy-Duty Alternative Fuel Infrastructure Corridor Coalition (WCC AFICC)

The mission of the WCC AFICC is to accelerate the modernization of west coast transportation corridors by deploying alternative fuel infrastructure for medium and heavy-duty vehicles and equipment in synergy with other investments. Public-private collaboration to plan projects, leverage funding, and construct modernized corridors with alternative fuel infrastructure will create jobs, increase domestic fuel supply diversity, reduce emissions, improve public health and support more robust medium and heavy-duty fleet operations.

In 2018, the WCC hosted a series of AFICC webinars focused on medium and heavy-duty alternative fuel infrastructure needs in Oregon and Washington. This webinar series also included informational briefings regarding medium and heavy-duty natural gas, propane, plug-in electric and hydrogen fuel cell electric technologies and related infrastructure.
