TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Future exploration spacecraft will need to operate in extreme thermal environments, with highly variable conditions for heat rejection by thermal radiation. Thermal storage is a critical technology for these missions, since it enables the spacecraft's thermal management system to be sized for average conditions instead of the least favorable. We propose a new technology for thermal storage based on an innovative, non-venting phase-change heat exchanger. Creare's technology overcomes some of the key limitations of phase-change heat exchanger technology. Our design maximizes the amount of phase-change material, eliminates large thermal resistances due to the poor thermal conductivity of the phase-change material, and accommodates differences in solid vs. liquid volume without a heavy structure. In Phase I we will prove the feasibility of this approach through thermal, fluid, and structural analysis; assessment of critical trade-offs; proof-of-concept demonstrations; and design of a prototype phase-change heat exchanger sized to meet requirements for future space exploration missions. In Phase II we will design, build, and demonstrate operation of the prototype phase-change heat exchanger.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Creare's technology can replace paraffin or water ice phase-change heat exchangers or water evaporation and venting systems that have been slated for use on future lunar orbiters. These spacecraft face extreme changes in thermal radiation environment each orbit, and Creare's technology can significantly reduce the mass needed for thermal storage. The technology could also be useful for rovers or planetary bases in which the thermal control system must be designed for highly variable conditions.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Phase-change heat exchangers built using Creare's technology can be used as part for thermal control systems in terrestrial vehicles, where systems must be compact, lightweight, and highly efficient. The basic heat exchanger technology has extremely broad applications. It can be applied using a wide range of materials and configurations. Heat exchangers built using the technology we propose can be used for applications including cryogenic recuperators, aircraft environmental control systems, and high-temperature recuperators for gas turbine engines.
