UNIVERSITY PARK, Pa., Sept. 15 -- Pennsylvania State University issued the following news release:
UNIVERSITY PARK, Pa. - Storing energy as heat is a proven pathway to address the challenge solar power faces when it's dark or cloudy outside by enabling the capture, storage and on-demand release of thermal energy. The process, called high-temperature thermal energy storage (TES), however, can be prohibitively expensive. Researchers at Penn State have found that steel slags - a rock-like waste byproduct of the steelmaking process - may potentially serve as a low-cost, heat storage candidate for TES applications.
They published their first-phase findings of a three-phase project today (Sept. 15) in Solar Energy. The first phase focused on id...
