Hydrogen storage capacity of commercially available carbon materials at room temperature

Abstract: The hydrogen storage capacity of five types of commercially available carbon materials with different nanostructures was measured at up to 8 MPa at room temperature using an apparatus based on a volumetric method with an error of less than 0.04 wt %/gr. The highest storage capacity of 0.43 wt % was obtained for purified HiPco™ single-walled carbon nanotubes (SWNTs). In the SWNTs, the hydrogen density in pores with a diameter of less than 1 nm was estimated to be a 0.022 g/ml, which corresponds to 31% of the de… Show more

“…[3] Since the SSA for two sides of a graphene sheet is 2620 m 2 /g [5] -2965 m 2 /g [6] , ~3 wt.% appears to be the limit for low-temperature, ambient pressure storage. This, along with low measured hydrogen uptake at room temperature, [3,7] and numerous errors in the measurements of hydrogen uptake by carbon nanostructures, led to loss of confidence in carbon's potential for hydrogen storage.…”

“…A lot of new carbon materials such as carbon nano tubes (CNTs), activated carbon, and hydrogenated nano-structural graphite (C nano H x ) have been researched to create more efficient hydrogen storage materials. [4][5][6][7][8][9][10][11][12] Among these new carbon materials, we have paid attention to hydrogenated nanostructural graphite. C nano H x is synthesized from graphite by the ball-milling under H 2 gas atmosphere.…”

“…Algumas dessas aplicações encontram-se atualmente em fase comercial, ao passo que outras estão ainda em fase de testes, como discutido criticamente num artigo de revisão publicado na revista Science 7 . Em particular, a utilização dos NC para armazenamento de hidrogênio é tema ainda controverso 29 . Atualmente, o alto custo, a falta de controle sobre o processo (tipo, comprimento e diâmetro do nanotubo formado) e limitações ao processo de purificação constituem sérios obstáculos para a maioria das aplicações dos NC.…”

“…Além disso, esse material deve ser estável ao longo da ciclagem de hidrogênio e possuir características termodinâmicas e cinéticas adequadas tanto para o transporte como para o desenvolvimento de dispositivos portáteis 29 , os quais poderiam ser aplicados para mover veículos com células a combustí-vel 38 . A tecnologia dos nanotubos de carbono representa uma nova fronteira para o armazenamento de hidrogênio, especialmente se esses materiais puderem ser modificados para armazenar grandes quantidades de hidrogênio à temperatura ambiente.…”
