I agree that the larger the area enclosed by the coil, the larger the storage capacity relative to the current and number of turns. I think the storage capacity of a superconductive coil is simply equal to the energy of the magnetic field created by the coil, which would be proportional to the product of the current, the area enclosed, and the number of turns; at least for a Helmholtz-style coil.
