New energy storage research from NREL, a U.S. Department of Energy national laboratory, has demonstrated a way to store and reuse heat underground to meet the heating demands of cold regions like ...

Researchers designed a novel heat pump that uses sound waves to move thermal energy, producing additional heat. The team from China produced an unprecedented amount of heat with their system, and ...

Phase change materials (PCMs) represent a pivotal class of substances that store and release thermal energy through reversible transitions between solid and liquid states. Their ability to absorb or ...
