A two-phase heat transfer system includes an evaporator unit configured to receive heat from a source, a liquid line fluidly connected to the evaporator unit, a vapor line fluidly connected to the evaporator unit, and a condenser. The condensing unit includes a thermal capacitance device and a condenser integrated with the thermal capacitance device. Methods of forming a thermal storage unit include preparing a honeycomb core to receive a phase change material, metallurgically bonding end pieces to the core, to thermally link the end pieces to the core, and bonding the end pieces together to form a seal for holding the phase change material within the core.
