Development of Dual Volume Cryogenic Hydrogen Storage System

摘要: We are developing cryogenic capable pressure vessels with thermal endurance at least 5 times longer than conventional liquid hydrogen (LH2 ) tanks that can eliminate evaporative losses in routine use while providing high storage weight and volume performance. The generation 2 vessel, installed onboard a Toyota Prius hybrid experimental vehicle, has demonstrated the longest driving distance on single LH2 tank hold time without losses. In addition to presenting basic concept recent progress vessels, this paper describes potential for greatly exceeding density of vessel through conformable dual containers better occupy box-shaped spaces vehicle. present design analysis shows promise delivering unprecedented Future work will focus demonstrating technology vehicle.© 2010 ASME
