Tradeoff analyses of the electrical power subsystem (EPS) utilizing various options such as nickel-hydrogen (Ni-H2) batteries, open-loop fuel cells, and regenerative fuel cells (RF/C) were conducted to determine the optimum evolutionary approach in the buildup sequence from an initial to an all-up growth space station. The analyses included all the interfacing subsystems that can be readily integrated with the EPS. These included the environmental control and life support subsystem (ECLSS), thermal control subsystem (TCS), and reaction control subsystem (RCS). The results show that the electrical power energy storage system design for the evolutionary stage is strongly influenced by: (a) new technology, (b) life-cycling cost, and (c) space station buildup architecture. This work was performed under Rockwell-sponsored IR D, Projects 316 and 317.
