氢(qing)(qing)以其(qi)(qi)纯净形式不(bu)燃烧碳，不(bu)产生热灰(hui)烬，并且(qie)几乎(hu)没有辐(fu)射热。氢(qing)(qing)极易(yi)燃，但是当氢(qing)(qing)泄漏时，它会迅速上升(sheng)到大气(qi)(qi)中，因此燃烧时间更少(shao)。氢(qing)(qing)气(qi)(qi)作为高度(du)压缩的气(qi)(qi)体，与其(qi)(qi)他(ta)任(ren)何燃料一(yi)(yi)样，需(xu)要(yao)明确的使(shi)用规则。氢(qing)(qing)已(yi)经(jing)(jing)使(shi)用了很长一(yi)(yi)段时间，不(bu)幸的是，仍然存在(zai)着(zhe)一(yi)(yi)种(zhong)误解，即缺乏对氢(qing)(qing)气(qi)(qi)已(yi)经(jing)(jing)在(zai)市场上的了解以及一(yi)(yi)种(zhong)有希望的能帮助工(gong)业和运输业脱碳的能源(yuan)载(zai)体的认(ren)识(shi)。下面氢(qing)(qing)气(qi)(qi)生产厂家介(jie)绍关于(yu)氢(qing)(qing)气(qi)(qi)的储存、压缩和运输指(zhi)南。氢(qing)(qing)原子氢(qing)(qing)很难(nan)存储，因为其(qi)(qi)能量密(mi)度(du)非常低。它是简单，轻(qing)的元素-比氦轻(qing)。氢(qing)(qing)气(qi)(qi)的能量密(mi)度(du)比天(tian)然气(qi)(qi)小(xiao)，能量密(mi)度(du)比汽油(you)(you)小(xiao)2700倍。按重(zhong)量计算，氢(qing)(qing)气(qi)(qi)所含(han)能量是汽油(you)(you)的。宁夏各种(zhong)规格(ge)氢(qing)(qing)气(qi)(qi)价格(ge)是多少(shao)
