The broader/commercial potential of this I-Corps project is the development of a reusable metal hydride-based device for energy storage. The project will provide a compact and inexpensive cooling device for a wide range of markets. Potential applications of the metal hydride technology are in batteries, hydrogen storage materials, and thermal energy storage to harness excess energy and provide on-demand sustainable energy. Current metal hydride-based device storage devices largely work only at temperature extremes, which limit their application in conventional storage systems. Thus, strategies are needed to develop storage devices for use at ambient conditions. The proposed technology may provide an efficient method for energy storage that will be a key enabler for future clean energy technologies.This I-Corps project develops a cooling device that is driven by solid-gas reactions between a pair of alloys and hydrogen. Hydrogen storage by metal hydrides is accomplished by an intermetallic alloy phase that has the ability to absorb and store atomic hydrogen in interstitial sites of the metal lattice. Forcing the intermetallic alloy phase to release the absorbed hydrogen leads to an endothermic reaction which results in cooling. Various metal hydrides have been investigated to determine the hydrogen absorption/desorption pathways and to identify the thermodynamic requirements necessary for dehydrogenation reactions with an equilibrium close to ambient conditions. Preliminary results have shown that at ambient conditions the metal hydride can be recharged 10,000 times with only 10% loss of capacity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目的更广泛/商业潜力是开发一种可重复使用的基于金属氧化物的储能设备。该项目将为广泛的市场提供一种紧凑而廉价的冷却装置。 金属氢化物技术的潜在应用是在电池、储氢材料和热能储存中，以利用多余的能量并提供按需可持续能源。当前的基于金属叠层的器件存储器件主要仅在极端温度下工作，这限制了它们在传统存储系统中的应用。因此，需要开发用于环境条件下的存储装置的策略。该技术可能提供一种有效的储能方法，这将是未来清洁能源技术的关键推动因素。I-Corps项目开发了一种冷却装置，该装置由一对合金和氢之间的固气反应驱动。通过金属间化合物的储氢是通过具有在金属晶格的间隙位点中吸收和储存原子氢的能力的金属间合金相来实现的。迫使金属间合金相释放吸收的氢导致吸热反应，这导致冷却。已经研究了各种金属氧化物以确定氢吸收/解吸途径，并确定具有接近环境条件的平衡的脱氢反应所需的热力学要求。初步结果表明，在环境条件下，金属氢化物可充电10，000次，仅损失10%的容量。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
