A method for transitioning between fuel cell and electrolysis modes in a Reversible Solid Oxide Fuel Cell (RSOFC) system includes measuring and recording sensor data indicating a status of components associated with an RSOFC system coupled to an electrical power grid, the system comprising an RSOFC unit, a hydrogen compression system, a hydrogen storage system, and a water supply, determining a state of the RSOFC system based on the sensor data through a conditional logic algorithm, and transitioning the RSOFC system between the fuel cell mode and the electrolysis mode based upon the sensor data and the system state.
