Hydrogen is cooled during storage in the form of a metal hydride. A storage tank or container with a metal hydride precursor is provided with at least one spiral cooling tube, configured with an elliptical cross-section. A coolant fluid is caused to flow within the spiral cooling tube. Hydrogen is combined with the hydride precursor to provide a metal hydride bed within the storage tank or container, and, while combining the hydrogen with the metal, heat is extracted through the spiral cooling tube. A swirling flow within the spiral cooling tube is used to improve the heat transfer in the system and enhance the hydrogen absorption process. Ferromagnetic nanoparticles in the coolant fluid are used within the spiral cooling tube. and electromagnets to establish a magnetic field interacting with ferromagnetic nanoparticles in the coolant fluid to establish flow and improve heat transfer.
