Less Carbon, More Chill Novel Refrigeration Approach Uses PCMs To Freeze, Cool Perishables

A technology developed by Oak Ridge National Laboratory works to keep food refrigerated with phase change materials, or PCMs, while reducing carbon emissions by 30%. More than 100 million household refrigerators in operation across the United States consume up to 2 kilowatts of electricity daily. These refrigerators contribute to energy … [continued]

Reused Car Batteries Rev Up Electric Grid

When aging vehicle batteries lack the juice to power your car anymore, they may still hold energy. Yet it’s tough to find new uses for lithium-ion batteries with different makers, ages, and sizes. A solution is urgently needed because battery recycling options are scarce. Researchers at Oak Ridge National Laboratory have … [continued]
