SRT is a small technology-oriented firm with a business focus on developing and licensing renewable energy technologies. It supports its R&D activities through internal resources, as well as grants and contracts from the federal government. Currently, SRT is developing an electrical energy storage and hydrogen production concept through cost-shar. In the SRT system, the hydrogen/bromine regenerative cell is used both as a fuel cell to generate electricity and as an electrolyzer to produce marketable hydrogen. Due to its reversible operation, it is used in an energy storage system, storing and dispatching electricity during off-peak and on-peak periods. Off-peak periods are those times of the. The possibility of using a reversible hydrogen/halogen cell for electric energy storage was first suggested in 1964. The proposed system includes a solid polymer electrolyte (SPE) cell, power conditioner and storage for hydrogen, bromine and hydrogen bromide. The hydrogen/bromine energy storage system has definite advantages over other battery syst.
