As the need for renewable energy is heightened, energy storage and distribution solutions must be developed. Hydrogen is an abundant energy source with the highest gravimetric energy density of all materials. It can be utilised in fuel cells to generate electricity, with only a water vapour by-product. For hydrogen storage and re-fuelling stations for vehicles, hydrogen compression is required to improve the volumetric energy density in storage tanks. It is proposed that sodium borohydride (NaBH4), a hydrogen carrier, could be utilised to transport and chemically compress hydrogen for refuelling stations. Chemical compression of hydrogen to over 1000 bar has been demonstrated in this study using either hydrolysis or methanolysis of NaBH4. Interest has been growing to improve the cost of closed-cycle regeneration of this borohydride energy carrier. A cost and efficiency analysis of the NaBH4 regeneration cycle using green energy demonstrates that it may be cost competitive with alternative methods of hydrogen transport, including using liquid hydrogen, ammonia, or liquid organic hydrogen carriers.

使用硼氢化钠化学压缩和输送氢气
随着对可再生能源需求的增加,必须开发储能和配电解决方案。氢是一种丰富的能源,在所有材料中具有最高的重量能量密度。它可用于燃料电池发电,只有水蒸气副产品。对于车辆的储氢和加氢站,需要对氢进行压缩以提高储罐中的体积能量密度。有人提出,氢载体硼氢化钠 (NaBH 4 ) 可用于为加氢站运输和化学压缩氢气。在这项研究中,使用 NaBH 4的水解或甲醇分解证明了氢气的化学压缩至超过 1000 bar. 人们越来越关注提高这种硼氢化物能量载体的闭式循环再生成本。对使用绿色能源的 NaBH 4再生循环的成本和效率分析表明,它可能与其他氢运输方法(包括使用液态氢、氨或液态有机氢载体)相比具有成本竞争力。
