The hybrid buses of today incorporate the normal internal combustion engine propulsion system along with the electric propulsion system. These hybrid buses are known for using diesel - electric fuel are are also referred to as hybrid diesel - electric buses. Recently studies have shown that these hybrid buses reduce greenhouse pollution by using small amount of biodiesel (20%) and relying more on electricity.
There are hybrid buses being manufactured and used. They are diesel electric hybrids and although they do not completely eliminate emissions they do lower the emissions produced by such engines.

Hybrid buses are becoming more common in metropolitan areas. Cities such as San Francisco, Phoenix and Baltimore have a hybrid fleet. An article at USA Today talks more about this trend: http://www.usatoday.com/news/nation/2008-01-21-masstransithybrids_N.htm
Transit systems are greening their fleets with hybrid buses. These vehicles release fewer green house gases and get better fuel efficiency. The buses use 50,000 gallons less diesel than regular buses. Environmentalists say that soot emissions have dropped over 95% and nitrogen oxides emissions are down close to 60% for each bus. You can save money on your commute and clean the air by taking a hybrid bus to work.
Used in trucks and buses. This type of braking system of pneumatic and hydraulic hybrid vehicles.
Allison Transmission manufactures fully automatic transmissions for commercial vehicles, military vehicles, and hybrid propulsion systems for transit buses.
In recent history for buses in London a Hybrid Technoligy bus has been brought out but unfortunately nobody is sure if it is Carbon fuel cell, H2o powered or solar.
