The PHP has many possible applications within NASA. These include distributed cooling systems for zero boil off cryogenic storage tanks, in particular for actively cooled shields that may be used to eliminate the need for internal mixing with spray bars. The PHP could also be used to provide distributed cooling for radiation shields and large optical elements used in infrared space science missions.
There are also Missile Defense Agency applications, such as surveillance systems incorporating LWIR focal planes that require cooling of focal planes and optics to temperatures less than 40K. In addition, there are many commercial applications such as cooling superconducting power lines, superconducting magnets for power generation and energy storage and MRI magnets for medical applications.
