A compressed air energy storage unit (100) having an electrical input and output circuit (4), compressor and expansion means and an artificially created compressed air reservoir (2), wherein the compressor and expansion means comprise a piston pump (200), the pistons of which consist of an electrically and thermally conductive liquid, e.g. galinstan, and which is switchable between pumping operation and generator operation. The invention further relates to a method for the production of a compressed air energy storage unit 100 of this nature, wherein at least some components are manufactured by 3D printing. |
