A Cleaner Way To Cool Refrigerated Trucks

Your produce and frozen foods could soon arrive at grocery stores in trucks that release fewer emissions. Northwest researchers are developing a clean technology to keep your food cool while it’s transported over hundreds of miles.

We’ve all seen semi-trucks idling outside grocery stores. They’ve got to keep their engines running to keep frozen foods frozen. Researchers at Pacific Northwest National Laboratory are working to replace the truck’s diesel cooling system with fuel cells. Fuel cells mix hydrogen and air to create energy. The byproduct is water. Researcher Kriston Brooks says that means fewer greenhouse gas and particulate emissions.

Brooks: “From the big picture of how much carbon dioxide we produce and other emissions, it’s pretty small. But it’s a start.”

Researchers will test the equipment in the summer by shipping groceries in California, Texas, and New York. Several grocery facilities already power their forklifts with hydrogen fuel cells.
