British startup Bactery has developed a battery that generates a continuous, low-level flow of electricity using naturally occurring soil microbes [1, 2].
The technology represents a potential shift toward sustainable energy by leveraging the biological activity already present in the earth. If successful, these reactors could provide a constant power source for remote sensors or electronics without the need for traditional chemical batteries or solar panels.
Product design engineer Ewan Comfort‑Keir said the company is focused on ensuring the technology is versatile. The reactors are designed to operate across different geographic regions and environments, regardless of the specific land composition [1].
"Our goal is to make these reactors work and produce power in every single soil type on the planet," Comfort‑Keir said [1].
Bactery is utilizing the natural metabolic processes of bacteria found in soil to draw electricity [1, 2]. This method turns the ground itself into a power plant by capturing the electrons released by microbes during their normal biological functions [1].
Because the system relies on existing microbial life, it avoids the environmental waste associated with the disposal of conventional batteries. The startup is currently working to refine the reactors to ensure steady output across diverse soil chemistry, and moisture levels [1].

This development signals a move toward 'energy harvesting' from the environment, reducing reliance on rare-earth metals used in traditional batteries. While the electricity output is currently low-level, the ability to generate power in any soil type could revolutionize agricultural monitoring and environmental sensing in remote areas where replacing batteries is impractical.
