Soil-Powered Fuel Cell Makes List of Best Sustainability Designs

A newly designed soil-powered fuel cell that could provide a sustainable alternative to batteries was recognized as an honorable mention in the annual Fast Company Innovation by Design Awards.

Terracell is roughly the size of a paperback book and uses microbes found in soil to generate energy for low-power applications. 

Previous designs for soil microbial fuel cells required water submergence or saturated soil. Terracell can function in soil with a volumetric water content of 42%

Terracell placed in Fast Company’s list of the best sustainability-focused designs of 2024.
