Energy is stored in the compression of a metastable degenerate Fermi electron gas contained in a compressed metallic base material subjected to a magnetic field in a high pressure cell. Heat energy is introduced to increase the energy of the compressed metastable degenerate Fermi electron gas. The increase in energy causes the magnetic field to increase so that the metastable degenerate Fermi electron gas is further compressed. Absorption of heat results in a decrease in the temperature. Energy can be withdrawn from The system by allowing the metastable degenerate Fermi electron gas to expand against the compressing magnetic field. To prevent development of fissures, the metallic base material is precompressed to provide an allowance for the volume of a metastable Fermi electron gas bubble to be created later.
