Researchers at the Pacific Northwest National Laboratory have developed hydrogen fuel cells they hope will replace diesel-burning refrigeration systems used to ship frozen foods. Researcher Kriston Brooks told Earthfix that the fuel cell is twice as efficient and emits water instead of greenhouse gasses or other particulates. Trucks outfitted with the new technology are being tested in New York, California and Texas.

“We wanted to verify that it would work in various climates in different times of year. Certainly it’s a lot more rigorous on a fuel cell and a (transport refrigeration unit) during the summertime,” Brooks said.

Hydrogen fuel cells have been applied to a number of applications, from portable cellphone chargers to trains.
