World’s first living cement can store electricity and power buildings from within

SMRTR summary

Danish researchers created living cement by embedding bacteria that store electricity within standard concrete. The innovative material, which outperforms traditional cement-based storage, can recover its performance when supplied with nutrients through a microfluidic system. This breakthrough could transform buildings from passive structures into active energy storage systems, potentially allowing walls and foundations to store renewable energy without relying on scarce battery materials.
