Light metal hydride-based hydrogen storage system: Economic assessment in Argentina
Motivated by the high potential for hydrogen production from renewable resources in Argentina, the economic feasibility of employing light complex metal hydrides as hydrogen storage materials for mobile applications in Argentina is explored for the first time. Three main costs are analyzed: green H-2, H-2 storage system based on Mg(NH2)(2)-LiH and storage tank. Considering the production of H 2 by electrolysis using wind energy, a cost of similar to 5 USD/kg H-2 is obtained. The cost of hydride matrix is crucial and competitive values are viable only if the synthesis route starts from Mg-0 and Li-0, allowing reducing the total hydride matrix cost from similar to 2200 to similar to 4900 USD. The cost of a modular configuration tank with 4 kg of H-2 capacity is estimated to be similar to 5300-6700 USD. A cost ratio higher than of 2:1 is obtained between storage systems based on amides and high pressure systems. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
