1. A device for pumping liquid hydrogen comprising, arranged in series:
an inlet for the liquid hydrogen to be compressed;
a first compression component, forming a first compression stage, comprising at least one assembly that comprises a piston that is translationally movable in a sleeve;
a second compression component, forming a second compression stage, comprising at least one assembly that comprises a piston that is translationally movable in a sleeve; and
an outlet for supercritical hydrogen,
further comprising a thermalization circuit comprising a first upstream end connected to a liquid hydrogen source, and at least one downstream end ensuring a thermal exchange between the liquid hydrogen and a shell,
wherein: the first compression component is configured for compressing the liquid hydrogen into a supercritical state,
wherein the second compression component is configured for compressing the supercritical hydrogen supplied by the first compression component to a pressure ranging between 200 and 1000 bar,
wherein the piston of the at least one assembly of the first compression component is translationally movable in the respective sleeve at a determined movement speed,
wherein the piston of the at least one assembly of the second compression component is translationally movable in the respective sleeve at a determined movement speed,
wherein the determined movement speed of the piston of the at least one assembly of the first compression component is independent of the determined movement speed of the piston of the at least one assembly of the second compression component,
wherein the first compression component and/or the second compression component is arranged in the shell forming a heat shield that is thermalized by a cooling fluid, and
wherein the thermalization circuit comprises a portion connecting the shell to a compression chamber of the first or second compression components and configured to transfer at least some of the liquid hydrogen that has thermally exchanged with the shell to the compression chamber of the first compression component.
