The long read: Scientists at Argonne develop new kind of thermal battery
Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed a new kind of thermal battery that can greatly increase the energy efficiency and cost-effectiveness of many industrial processes and shows great promise for use in the solar industry. Liz Thompson reports that Argonne’s Thermal Energy Storage System (TESS) can rapidly capture and store surplus heat so that it can be used as needed. With its pioneering modular design and material advancements resulting in greater efficiency, TESS is a big step forward in thermal battery technology.
