The effect of greenhouse gas (GHG) emission causes a rapid change in our earth's temperature. Fossil fuel contributed up to 65% of total GHG in 2014. Renewable energy has come to the solution of the global warming problem. Hydrogen is accepted globally as clean energy because its emission is water. Due to its low-density, hydrogen is stored in several ways, which are liquid hydrogen, liquid organic hydrogen carriers (LOHCs), and ammonia. Ammonia is the most efficient form of hydrogen. Hence, the utilization of ammonia as fuel in vehicles is still rare. Therefore, a new design for an ammonia pressure vessel is needed. Polyethylene terephthalate (PET) and polypropylene (PP) are proposed as liner material, while carbon and glass fiber are used as an option to overwrap the liner. A clear assessment must be done from every sector of safety for an ammonia pressure vessel as a fuel tank storage. Based on Regulation No.67 United Nations Economic Commission for Europe (UNECE), It should not be leak after the impact test. The finite element method proposed to analyze and get the optimum material composition for the ammonia storage system. Based on minimum damage and plastic deformation in vessels, stacking sequence [90/±90/90]3s of CFRP-PET is the best choice. In practical, however, that stacking sequence cannot be used. From the burst test simulations, the optimum composite thickness is 12 plies for both material composition of PET-CFRP and PET-GFRP with the stacking orientation of [±57]6s, [90/±43]4s, respectively. Six plies are the optimum thickness for [0/±82]4s of PP-GFRP, and four plies are the optimum thickness for [±51]6s of PET-CFRP
