How Much Hydrogen Does a Hydrogen Fuel Vehicle Consume per 100 Kilometers?

[AngelinaFitz]

For sedans, approximately 1 kilogram of hydrogen is consumed per 100 kilometers. Here are some relevant details: Density: Hydrogen has a very low density. Even when stored as a liquid in cryogenic tanks or as compressed gas in cylinders, the amount of energy that can be stored in these spaces is quite limited, making hydrogen vehicles more constrained compared to other types of vehicles. Additionally, hydrogen should not be allowed to leak extensively into the atmosphere, as it could potentially damage the ozone layer. Some research has explored using special crystalline structures to store hydrogen in higher-density environments, which could also enhance safety. Extraction: Hydrogen must be extracted from fossil fuels or other energy sources, leading to energy loss (since the conversion from other energy sources to hydrogen and back to energy is not 100% efficient). Because every energy source has its drawbacks, transitioning to hydrogen involves political decisions regarding how to generate this energy.
