Recently, we have proposed an experiment to test the persistence of the polarization in a fusion process, using a powerful laser hitting a polarized HD target. In the present contribution, we first examine new possibilities towards this goal, in view of recent developments of new polarized D samples presented in this conference. We then advocate that sizeable amounts of polarized DT fuel could be obtained by the Nuclear Dynamic Polarization (DNP) of DT molecules, if a successful protocol for the DNP of the HD analog isotopic molecule could be established. We suggest that a revival of an early HD DNP experiment performed more than forty years ago, should be undertaken, taking advantage of detailed polarized HD properties revealed by thoroughly repeated static polarization of HD targets during the last ten years.
