UPS first in industry to purchase hydraulic hybrid vehicles
As part of a public-private partnership to increase the commercial availability and use of alternative fuel vehicles, UPS announced its first purchases of a little-known technology – the hydraulic hybrid vehicle – that promises dramatic fuel savings and environmental benefits.
The technology, originally developed in a federal laboratory of the Environmental Protection Agency, stores energy by compressing hydraulic fluid under pressure in a large chamber.
Disclosing the results of its road testing on Detroit routes for the first time, UPS and the U.S. Environmental Protection Agency (EPA) said the prototype vehicle had achieved a 45-to-50 percent improvement in fuel economy compared to conventional diesel delivery trucks. UPS believes similar fuel economy improvements and a 30 percent reduction in CO2 are achievable in daily, real-world use. The EPA believes the technology can perform equally well in other applications such as shuttle and transit buses and refuse pick-up trucks.
UPS will deploy the first two of the new HHV’s in Minneapolis during the first quarter of 2009.
UPS’s current “green fleet” totals more than 1,600 low-carbon vehicles, including all-electric, hybrid electric, compressed natural gas (CNG), liquefied natural gas (LNG) and propane-powered trucks.
