A High Efficiency, Reversible Flow Battery
System for Energy Storage
Scott Barnett, Robert J. Braun, and Robert J. Kee
Summary: A solid oxide fuel battery for high efficiency energy storage
Description: The invention relates to a reversible solid oxide electrochemical cell that may
operate in two modes: power generation (discharge mode) and electrolytic fuel production
(charge mode). A thermal system that utilizes a solid oxide fuel battery and is inclusive of
selection of operating conditions that may enable roundtrip efficiencies exceeding 80% to be
realized is disclosed. By leveraging existing solid oxide fuel cell technology, the system concept
is applicable to energy storage applications on the kW to MW scale, and is limited by the size of
the fuel storage tank which may be tailored to specific applications.
