Electric vehicles are clean and efficient, but limited in the distance they can travel between battery charges. Capstone microturbines are used in hybrid electric vehicle (HEV) applications as a range extender, acting as an onboard battery charger for increased fuel economy, quieter operations, reduced emissions, and higher reliability. Thus, the need for daytime battery charging or battery swapping is eliminated.

Capstone Products

Powered with batteries charged by an onboard Capstone C65 MicroTurbine, the ECObus combines the maneuverability of a standard bus and the on-the-fly continuous power of an electric trolley or streetcar. "Urban transport must be green, comfortable and economical. That's why when creating a new ecobus, we drew our attention to Capstone microturbines. Microturbines enable increased mileage without refueling (the reduction of fuel consumption reaches up to 40%). Absence of oil and cooling fluids resulted in simpler maintenance and extended maintenance intervals, which significantly reduced our operational costs. At the same time, ecological features of microturbines ensure a low noise level and low NOx and CO emissions. Ecobuses obtain sheer benefits for use in resort areas and densely populated cities where ecological features of transport are of the highest priority."
