The growing vehicle fleet around the world has intensified the search of alternative renewable fuels and become an important area of research. Bio-ethanol is by many considered one of the most important alternatives to diesel and gasoline, mainly because it does not contribute to the greenhouse effect. - Advanced Diesels Bus
The advanced diesel bus uses advanced engine systems and aftertreatment emission reduction devices, usually in conjunction with lower sulfur fuel. - Cleaner Bus Fleets in New York City
The Department of Transport's bus system carries over 114 million people annually through a mix of local and express bus services provided by seven private, franchised bus companies. - CNG Bus
The compressed natural gas (CNG) bus uses a spark-ignition engine to burn natural gas, which contains mostly methane obtained from fossil resources. - CNG vs. Diesel buses in Perth, Australia
This is an explanation of the city of Perth's 1998 decision to run their bus fleet with diesel buses and low sulfur diesel instead of converting it to natural gas. The decision results from a study which compares clean diesel, CNG and LPG on environmental and economic reasons. - Conventional Diesels
Cleaner conventional buses meet more stringent emissions standards. - Electric Bus
The battery electric bus is powered by electrochemical batteries which are charged using electricity from stationary power plants. - Ethanol Bus
The ethanol bus runs on alcohol which can be produced from a variety of renewable biological resources. - European Automobile Manufacturers Association
- Fuel Cell Buses
The fuel cell bus employs a novel technology totally different from the internal combustion engine, which converts chemical energy directly into electric energy used to power the vehicle. - Georgetown University Fuel Cell Bus Program
The program is dedicated to support the development of fuel cell technology and assist industry in commercialization of fuel cells for transit applications. Its transit buses are demonstrated at various occasions in the U.S. - Hybrid Electric Bus
Hybrid electric vehicles (HEV) have two power sources. One converts fuel into useable energy, and the other, an electric motor powered by an advanced energy storage device, lowers the demand placed on the first power source. - LPG Bus
