Here is a video which is pregnant with real world ideas about where to go with the Holmlid technique and SPR (surface plasmon resonance). I think the "future will be small" for dense hydrogen - in the sense of merging with microlithography for high value products.
https://www.youtube.com/watch?v=3J9aUQSK_QE&html5=1 Since Holmlid has found that green laser light works to densify hydrogen on a catalyst, we can assume that SPR for iron oxide is in resonance with this light 532 nm. Sometimes 266 nm (UV) harmonics are seen from YAG lasers - so the precise stimulant for making dense deuterium could be in this range and supplied by a semiconductor diode. If the dense material is applied to a chip and diode array, and the shelf life is adequate, it could be arguably possible to make a battery or heat source which will last a very long time. Heck, one microgram of dense deuterium represents about 30 kWhrs of thermal energy. If converted to electricity via TEG at low 10% efficiency, that could power an iphone or laptop into the next decade :-) There is probably (hopefully) a safer but less efficient way to use dense hydrogen than nucleon disintegration.
