So does this new form of H take more energy to produce than it contains - like the H used for fuel today?
Unknown
Yes, unless triggered into a mode where nuclei actually fuse and release more energy than the storage process needs. Doing that repeatedly on demand is the unsolved trick. MUCH data exists that it happens sporadically....though that is denied by the hot fusion physics types.
Annihilation process—46% potentially useful energy from the mass conversion, with losses attributed to neutrino production. Aneutronic process—no neutrons produced or released.

It is NOT a primary energy source but itself. It takes application of high temps and pressures to achieve this H(0) state.
It may have applications in FUSION based reactors, where that could be considered a primary energy source were FUSION to be shown to actually work ...
