Researchers at Penn State are repurposing steel slags as a low-cost option for high-temperature thermal energy storage (TES) to address the intermittency of solar power. The project involves evaluating the morphological structure of three types of slags for TES applications, with the goal of reducing steel slag waste. This research aims to find a solution to the challenge of storing solar energy for later use when sunlight is not continuously available, offering a promising avenue for sustainable energy storage solutions.
