储氢研究进展

氢能是21世纪主要的新能源之一。作为一种新型的清洁能源,氢的廉价制取、安全高效储存与输送及规模应用是当今研究的重点课题,而氢的储存是氢能应用的关键。储氢材料能可逆地大量吸放氢,在氢的储存与输送过程中是一种重要载体。本文综述了目前所采用或正在研究的主要储氢材料与技术,如高压气态储氢、低温液态储氢、金属氢化物储氢、化学氢化物储氢、吸附储氢、金属有机骨架储氢等,比较了各种储氢的优缺点,并指出其相关发展趋势。

Progress of Research on Hydrogen Storage

Hydrogen energy is one of the most important new energies in the 21st century. As a new type of the clean energy, low cost hydrogen-production, safe and high-efficient storage and transport, and large-scale utilization techniques have been received much attention. Hydrogen storage technology is the linchpin in hydrogen application. Hydrogen storage materials, which are important carriers during hydrogen storage and transport, can absorb and desorb hydrogen reversibly. In this paper, most used or under-research hydrogen storage materials and technologies such as high-pressure gas storage, low-temperature liquid storage, metal hydrides, chemical hydrides, adsorption/absorption of hydrogen, and metal-organic-frameworks (MOF) are reviewed. The advantages and disadvantages of vaious hydrogen storage technologies are compared. The trend of the hydrogen storage technology is also introduced.
