一种新型储氢方法——水合物储氢的研究概况与发展方向

Hydrogen stored in hydrates——A novel hydrogen storage method

指出了氢能对人类可持续发展的重要意义,介绍了一种新型的储氢方法——采用水合物储存氢气的方法,主要从Ⅰ型、Ⅱ型、H型、半笼形等不同的储氢水合物结构展开论述,介绍了国内外采在水合物储氢方面的研究进展。这门技术还达不到实用的储氢密度,还处于起步研究阶段,不同研究者的研究结果有很大差异,所以为了提高这门技术还有很多工作有待进行。最后,从3个方面指出了今后应该进一步开展研究的重要内容。

A novel hydrogen storage method—hydrogen stored in hydrates is introduced.Hydrogen can be stored in different hydrate structures,such as structure Ⅱ（sⅡ）,structure Ⅱ（sⅡ）,structure H （sH）and semi-clathrate structure,etc.Related research works are reviewed comprehensively.Although the present results for hydrogen storage in hydrates can not meet the requirement of practical application,this technology is promising.Research results from different scholars are inconsistent,therefore,this technology needs to be improved through extensive research works.Finally,three directions for future study are suggested.
