Radiative Cooling and Cold Storage

Researchers from the University of Colorado, Boulder (CU-Boulder) will develop Radicold, a radiative cooling and cold water storage system to enable supplemental cooling for thermoelectric power plants. In the Radicold system, condenser water circulates through a series of pipes and passes under a number of cooling modules before it is sent to the central water storage unit. Each cooling module consists of a novel radiative-cooling surface integrated on top of a thermosiphon, thereby simultaneously cooling the water and eliminating the need for a pump to circulate it. The microstructured…

Scalable Architecture for EV Power Electronics

The University of Colorado, Boulder (CU-Bolder) and its project team will develop new composite SiC power converter technology that achieves high power and voltage conversion (250 VDC to 1200 VDC) in a smaller package than ever achieved due largely to improved switching dynamics and reduced need for large passive energy storage components. Also, utilizing higher system voltage in vehicular power systems has been proven to enable vehicle manufacturers to use thinner and lighter wires and improve vehicle powertrain system efficiency. The team seeks to demonstrate the power converter as an on-…
