日前,隶属美国能源部的萨凡纳河国家实验室(Savannah River。National Laboratory,SRNL)成功研发出了一套便携式电源系统,为该产业的未来发展铺平了道路。SRNL新电源系统的研发,与三氢化铝(alane)的使用不无关系。三氢化铝质地较轻,而且与液态氢相比,相同体积的三氢化铝储存的氢是前者的两倍,因而对于便携式的电池系统而言,它是最好的选择。事实上,氢的能量超过任何燃料,每千克可发出33千瓦时的能量。然而,业内所面临的挑战是需要找到一 Recently, the Savannah River National Laboratory (SRNL), part of the U.S. Department of Energy, successfully developed a portable power system that paved the way for the industry’s future. The development of the new SRNL power system is not tied to the use of alane. Aluminum trihydrate is light and, compared to liquid hydrogen, the same volume of aluminum trihydride stores twice as much hydrogen as the former, making it the best choice for portable battery systems. In fact, the energy of hydrogen exceeds any fuel, giving 33 kWh per kilogram of energy. However, the challenge in the industry is to find one
