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.
