While hydrogen technologies are rapidly taking advantage of the research results of the last years, some more effort is necessary to evaluate the impacts that such technologies have on the environment and on the use of existing energy resources compared to conventional technologies. In automotive applications, e.g., the adoption of fuel cell as power generator surely abates emissions during operation but still required an accurate evaluation of impacts during its production process. As a logical follow-up to that analysis, an LCA study about pressure vessels for hydrogen storage in vehicles was performed. The main scope of the study was the definition of parameters suitable for a comparison between gasoline/diesel tanks and hydrogen tanks for automotive applications. The vessels are made of aluminium and externally reinforced with a carbon fibre wrapping. The carbon fibre production process was particularly analysed in order to acquire reliable inventory data for the analysis.While hydrogen technologies are rapidly taking advantage of the research results of the last years, some more effort is necessary to evaluate the impacts that such technologies have on the environment and on the use of existing energy resources compared to conventional technologies.

The vessels are made of aluminium and externally reinforced with a carbon fibre wrapping. The carbon fibre production process was particularly analysed in order to acquire reliable inventory data for the analysis. From the analysis it can be noticed that the contribution of the materials production is generally more important than that of the work done on them. The contribution in terms of natural gas is mainly due to the oven where polymerisation occurs. For this reason no other energy mixes were analysed, as the data available on e.g. aluminium production are independent of the country mix.
