The (B)pack by (B)energy is a portable energy storage system designed to store biogas when connected to a biogas digester. The storage pack’s modular design operates through pressure equalization between the backpack and any biogas digester. The backpack straps allow transport of the (B)pack to facilitate the sale of biogas. When used for cooking the (B)pack is connected to a biogas stove and the gas is pushed out by placing a weight on the bag.
