Bionic Hydrogen Battery

Festo’s BionicHydrogenBattery system presents a novel biotechnological approach to hydrogen (H₂) management. It utilizes Thermoanaerobacter kivui bacteria to convert H₂ and carbon dioxide (CO₂) into formic acid (CH₂O₂), a stable liquid facilitating energy-efficient storage and low-risk transport. This fully automated process operates under mild conditions (approx. 65°C and 1.5 bar), contrasting with traditional energy-intensive hydrogen storage methods. The same bacteria can also reverse the process to release hydrogen on demand.
