A Chilling Innovation

Beating the heat might become a little easier, thanks to a new material developed at PNNL that offers outstanding refrigerant capacity and high thermal conductivity. The novel material shows promise for many advanced chiller applications, including air conditioning in buildings, U.S. Navy vessels and automobiles, as well as for power generation. The tiny structure is a metal organic framework—or MOF—overlaid on a porous carbon material using a unique method developed by PNNL. While the material development was initially funded through PNNL’s Laboratory Directed Research and Development program, further development and synthetic methods to scale up production and enhance performance are being supported by the U.S. Navy Military Sealift Command and DOE’s Geothermal Technologies Office.
