Alternative Fuels and Advanced Technology VehiclesOverview The purpose of these Alternative Fuel and Advanced Technology Vehicle resources is to encourage, educate, and equip fleets with the right resources to advance the choice in using alternative fuels, alternative-fueled vehicles and advanced technology vehicles. The Maryland Department of the Environment (MDE) has several programs that help Marylanders clean the air. The programs are geared towards vehicle maintenance and inspection, mass transit, and partnering with other organizations to provide alternative fuel infrastructure and emissions-reduction capabilities.Alternative Fuels (AF) Alternative fuels are any fuels other than petroleum based fuels. Some examples of alternative fuels are: compressed natural gas (CNG), biodiesel, electricity, ethanol, liquefied petroleum gas (propane), methanol and hydrogen.More Information on Alternative FuelsAdvanced Technology Vehicles (ATVs) An Advanced Technology Vehicle utilizes new or emerging technology to achieve improved fuel economy and reduced emissions. Common examples include gas-electric hybrid vehicles, electric vehicles, and fuel-cell powered vehicles as well as vehicles that employ other new technologies that increase fuel efficiency.More Information on Advanced TechnologyFunding Sources A variety of resources are available to assist with the purchase and infrastructure of low-emission, advanced technology, and alternatively fueled vehicles.More Information on Funding SourcesAdditional Links Links to information and programs related to Alternative Fuels, Alternative Fuel Vehicles and Advanced Technology Vehicles.Additional Links
