MIT researchers develop concrete foundations that act as energy storage

Material scientists at MIT have developed a method to transform standard concrete into a massive energy storage supercapacitor. By mixing cement and water with conductive carbon soot, researchers can create a microscopic electrical network within the hardening material.

This technology allows building foundations and road surfaces to store solar energy directly, offering a potential alternative to expensive and resource-intensive lithium-ion batteries. Unlike traditional batteries, which require minerals like nickel and cobalt and pose fire risks, this concrete-based system utilizes common construction materials to store enough electricity to meet daily power demands.

In a related trend toward integrated renewable energy, researchers are also advancing photovoltaic technology to turn building facades into power plants. New developments in cell technology and materials allow solar modules to be integrated into facades, mimicking the appearance of wood, stone, or brick, which expands energy generation opportunities beyond traditional rooftop installations.
