Cell-En is building a microbial fuel cell system that functions as a “wherever, whenever” off-grid power source by harvesting electrons generated when microbes break down organic waste. The platform, branded as “Cell-En Technology,” solidifies the power-generation core to boost output efficiency and enables local procurement of both microbes and nutrient feedstocks, supporting energy self-sufficiency while simultaneously reducing food and agricultural waste. The company envisions deploying its units to enhance community resilience against climate-related disasters by providing phase-free, sustainable electricity independent of existing grids. With the proceeds from its latest financing, Cell-En will scale the device for outdoor demonstrations, advance proofs of concept with corporate and municipal partners, pursue joint research with academic institutions, and expand hiring. Founded in August 2023, the startup’s microbial power technology was selected in July for the Tokyo Metropolitan Government’s FY2025 Next-Generation Renewable Energy Social Implementation Program. Cell-En has raised ¥150 million to date through a blend of equity and subsidies, and it is currently focused on maturing its prototype rather than generating revenue.
