Here is another way that I tried where I copied the formula from the web;

Net Gravitational Acceleration g' -0.315072129 m/s2
1-p'/p -0.032128514 m/s2
Object Density p 996 kg/m3
Fluid Density p' 1,028 kg/m3
Buoyant Force Fb 1,013,473 N

The idea was that I could back in F=MA and multiply the Buoyant Force * g' * the mass and come up with the energy potential. Should I put in m' - the differential mass - instead of the mass?
This was the last attempt that I made before posting the thread. I think that I am applying what you said but I am not quite sure. Does this method accomplish the Energy Density method of calculating Buoyant energy?
