Researchers at MIT are exploring the potential of creating concrete that can function as a battery or supercapacitor, offering a novel approach to energy storage. By adding conductive carbon black to the concrete, they have achieved a proof-of-concept material that can store 300-watt hours per cubic meter. This technology could revolutionize energy storage in various applications, from building foundations to grid storage and even roads. While there are challenges to overcome, the possibilities are intriguing and could have a significant impact on our energy infrastructure.
