Environmental and economic evaluation of the high-pressured and cryogenic vessels for hydrogen storage on the sedan

This paper carried out the environmental and economic evaluation for the hydrogen storage technologies on the sedan with Type 3 and Type 4 high-pressured and cryogenic vessels based on life cycle analysis (LCA) method. It is found that Type 4 high-pressured vessel manufacture emits minimum greenhouse gas (GHG) with 5539 kgCO2 eq, which is lower than Type 3 high-pressured vessel of 7219 kgCO2 eq and cryogenic vessel of 135 000 kgCO2 eq in their whole life cycle. The economic analysis shows that Type 4 high-pressure vessel has the lowest cost of 10.4 US$/kgH2 and the minimum energy consumption of 5.2 kWh/kgH2, which is lower than Type 3 high-pressure vessel and cryogenic vessel. With this result, Type 4 high-pressure vessel is a promising choice for hydrogen mobility on the sedan regarding its environmental impact and economic performance.
