| 摘要： | LLNL is 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. These pressure vessels can be fueled with ambient temperature H2 and/or LH2. When filled with LH2, these vessels contain 2-3 times more fuel than compressed H2 tanks at room temperature. LLNL has demonstrated the concept onboard two vehicles. The generation 2 vessel, installed onboard a Toyota Prius hydrogen hybrid, demonstrated the longest driving distance on a single LH2 tank and the longest LH2 hold time without evaporative losses. The generation 3 vessel, now under construction, promises to maximize packaging efficiency by minimizing insulation thickness while still providing acceptable thermal endurance. |
