Hydrogen is current potential for new energy applications. Thus, Methods of hydrogen storage have been widely discussed for the advancement of hydrogen and fuel cell power technologies since the problem of hydrogen storage has become the bottleneck for adoption of hydrogen as energy carrier. The objective of this research is to record the detailed experiment procedure to synthesize and characterize the adsorbent developed from sugarcane bagasse. The scope of project work includes the synthesis of adsorbent produced from environmentally friendly agriculture waste - sugarcane bagasse which consists of high cellulose content, and followed by the characterization of the new series of chemically activated carbon. Important findings and discussion of the research work are also discussed. Activating agent of ZnCl2, KOH and NaOH solutions with different concentration were used for chemical activation before undergoing the carbonaceous stage. The sample is washed with distilled water before characterization is performed. Effect of type of activating agent and its concentration on the porosity development were discussed. Characterization criteria of porosity, pore size distribution, surface roughness using SEM and carbon content using EDX analysis were discussed in Chapter 4. The SEM images show that the smooth, spongy and uniform pore structure is obtained by activation ofKOH and NaOH solutions if compared with ZnCk activated carbon. Other criteria such as specific surface area, micropore surface area, pore volume, density, and pyrolysis condition that will affect the hydrogen adsorption were also discussed in literature review and discussion.
