EPA Uses Webasto as Vehicle Heating Partner in Hydraulic Hybrid Project

The US Environmental Protection Agency (EPA) selected Webasto as its partner to provide idle-free cab heating for its Full Series Hydraulic Hybrid Vehicle (HHV) Yard Hostler prototype. (Earlier post.)

The EPA will introduce and exhibit the HHV Yard Hostler at the Word Maritime Day Parallel Event at Chelsea Piers in New York City on 16-18 October 2009.

With HHV technology, the stop-and-go fuel efficiency of yard hostlers is improved by 50 to 60% and CO2 emissions are reduced by more than 30%. The energy recovery technology used to stop the vehicle also reduces brake wear by 75%, increasing the net operating savings substantially.

It is estimated that the use of each high-efficiency yard hostler could save a terminal operator more than 1,000 gallons of fuel per year. When this technology is manufactured in high volume, it has the potential to recoup the hybridization costs from fuel and maintenance savings in three to five years. Hydraulic Hybrid Vehicles rely on proven innovative technology which has been successfully demonstrated in package delivery vehicles, shuttle buses, refuse trucks, light duty work trucks, and SUVs.

The Webasto technology—the Air Top 3500—used in the HHV Yard Hostler is already in mass production and is the country’s best-selling air heater line, offering idle-free heating of vehicle interiors and cargo spaces. Idle reduction is a key design feature of HHV technology and, without idle-free heating, that wouldn’t be feasible in the cold operating conditions prevalent at ports throughout much of the year, Webasto said.

The Air Top 3500 weighs only 13 lbs, produces up to 11,942 btu/hr and, at a full load, uses less than a pint of fuel each hour. WPNA is the North American subsidiary of the Global Comfort Solutions (GCS) Business Division of Munich, Germany-based Webasto AG, one of the world’s largest suppliers of vehicular parking and auxiliary heating and ventilation. In 2008 Webasto produced over one million heating systems, which are widely fitted to cars, trucks, buses and defense and specialty equipment globally.

I don't understand why any automaker hasn't yet proposed a pick up integrating this HHV with a diesel motorisation. It is a proven technology, doesn't require expensive batteries or rear-earth based electrical motor.

Sounds like it is too simple to seduce our auto industry

For quite some time now there exist vacuum panel insulation and Dewar flasks (thermos bottles). Use an insulated tank to store heat for many days. Foam glass could also work. ..HG..
