Catalyzing Commercialization: New System Freezes Food Faster at Lower Cost

July
2018
Catalyzing Commercialization
In the U.S., 70% of consumed food passes through a cold chain, an uninterrupted series of temperature-controlled storage and distribution activities. Globally, maintaining these cold chains consumes one-sixth of all electricity generated and produces 30 billion metric tons of CO2 per year. Traditional vapor-compression heat pumps have low efficiencies, use refrigerants with a high global warming impact, and are unable to provide dynamic cooling capacity. A new technology will dramatically change this picture by first complementing, and eventually replacing, vapor-compression cycles.

The ChE in Context
Nada Marie Anid
According to the U.S. Dept. of Energy’s (DOE) Advanced Manufacturing Office, manufacturing contributes almost $2.2 trillion per year to the U.S. gross domestic product and employs 9% of the nation’s workforce. For every dollar spent in manufacturing, $1.81 is added to the U.S. economy. Moreover, the manufacturing sector accounts for 30% of U.S. energy use and about 75% of all U.S. patents.
