Description

一种金属化合物储氢装置
技术领域
本发明涉及储氢技术领域，尤其涉及一种储氢装置。
背景技术
现有的储氢方式，通常采用压缩氢气至5000磅（340大气压）及10,000（680大气压），需耗能36兆焦耳/千克及47兆焦/千克，对应于30-40%氢的低热值（LHV），非常耗能。
结论利用压缩气体存储氢非常耗能。
发明内容
为了解决现有储氢方式存在的上述问题，本发明提供了一种金属化合物储氢装置。
本发明为实现上述目的所采用的技术方案是：一种金属化合物储氢装置，储氢罐1内设有金属化合物层2。
所述金属化合物层2为金属氢化物细粉。
本发明的金属化合物储氢装置，利用金属化合物储氢可低压储存并增加储存量─低压储存，解决传统高压储存之安全性疑虑。
附图说明
图1是本发明金属化合物储氢装置原理图。
图中：1、储氢罐，2、金属化合物层。
具体实施方式
本发明的金属化合物储氢装置如图1所示，储氢罐1内设有金属化合物层2，金属化合物层2为金属氢化物细粉。金属氢化物（LaNi4.25Al0.75）细粉反复吸氢和放氢动作，经过1周期（左图）和10个循环。吸收时金属氢化物扩大氢及释放后形成合金氢，其膨胀和收缩过程不能过度限制。若大量的金属氢化物粉末由于扩大限制或空间不足，压力将在容器壁上并可能最终变形或损坏容器。如何增加储存的氢密度是最关键的问题。使用合金氢存储氢是热驱动的过程。需在充放氢气过程把热量处理掉。充氢时传热比放电更苛刻，因为充气时间必须很短，而放电时间可延长几小时，一定要考虑氢化物容器的传热能力。
金属化合物储氢瓶规格：高储存密度：~120 grams/liter(金属化合物储氢)，~71grams/liter(液态储氢)，~0.09 grams/liter(传统钢瓶储氢)。低储存压力320psig(在环境温度条件下的金属化合物储氢压力)，5000 to 10,000 psig(高压钢瓶储氢)；若要达到使用金属化合物储氢钢瓶相同之储存量时，需要提高储存压力置15,000 psig.液态储氢可达相对低压，但其需要维持储存装置于-253°C (-423°F)之低温可多个串并联(例如60公斤氢储量，可串联8个8公斤氢储量罐)。
金属化合物储氢瓶规格/成本，充填时间(5kg为例)6-8mins (金属化合物储氢)3-5mins (高压钢瓶储氢)；金属化合物储氢罐重量百分比量产3.2 %/wt，实验室6.8 %/wt(超越US DOE 2025目标)。储存量3倍(300 psi金属化合物储氢罐储量对比10,000psi 高压罐储量)，金属化合物储氢罐成本每公斤约US55；量产后价格可降至非常便宜。
