Yes, I'm aware that this has been suggested before, but I still have hope for a TPT Cold Fusion system.
Palladium (PLDM)
Color: Bright grey.
Pressure tolerance: Invulnerable.
Melting point: 1555 degrees celsius.
Resists acid corrosion: No.
Blocks pressure: Partially.
Electrically conductive: Yes (with NSCN or PSCN; absorbs energy similar to VIBR but only with SPRK and doesn't explode).
Unique factors:
Can absorb a large amount of HYGN. When charged with NSCN, HYGN absorption is increased. Upon increased apsorption and saturation, absorbed HYGN begins to fuse and the process heats the PLDM to about 1000 degrees celsius. Fused HYGN is expelled from PLDM as NBIS (explained below). If PLDM is melted, expels all absorbed HYGN. If charged with PSCN, safely releases stored HYGN.
NBIS - Noble gas isotope. Identical to NBLE, but has an extremely short half-life of about 1 second and decays into HYGN (1 pixel of NBIS ---> 1 pixel of HYGN) unless quickly introduced to NEUT (2 NEUT + 1 NBIS = 1 NBLE).
Shouldn't it be HYGN instead of HYDR? Other than that, this is an interesting idea.
sounds like an interesting way to store hydrogen. could there be a way to release it? like leading pipe away from the paladaim? just to say, it sounds like spnge for hygn. just sayn'. perhaps if you tack on some other wonderful idea, then it will be perfect. is it flammable when hygn is "inside" it btw? oh, and a potential use is sorting oxygn and hygn from electrolysis. i currently have no more ideas, so... ill add to this later.
As I said before, I added this to my mod (not the new stuff, but your older suggestion).
