A cover, sample tray and base may form a hydrogen storage engineering properties analyzer. In at least one embodiment, the sample tray includes a plurality of cooling fins, each of which includes a sample well therein. A variety of hydrogen storage materials may be loaded into and unloaded from each sample well by way of a respective sample well opening. The combined cover and sample tray define at least one plenum which may be in fluid communication between a source of pressurized hydrogen gas and each sample well. The cooling fins may be received by a cooling chamber defined within the base and configured to receive a through-flow of heat-exchange fluid. Certain embodiments may include one or more pressure transducers in fluid communication between the plenum and hydrogen source, and thermal transducers connected to portions of the cooling fins.
