The ideal fuel would be pure hydrogen. Other factors that need to be considered in assessing the merits of different fuels are the moisture content and the ease of extraction, transportation and utilization. Coal and petroleum seem to have organic origins. We are more certain of coal’s plant-derived origin, although the exact mechanics of the process are not always agreed upon. Most believe in an organic origin for petroleum. Most fuels come directly or indirectly from carbohydrates, vegetable matter which is the result of photosynthesis occurring in green plants.

Hydrogen Storage Hydrogen can be stored as a gas, liquid, or as a part of a solid metal, polymer or liquid hydrid. Studies have indicated that large-scale storage could take place with gaseous hydrogen underground in aquifers, depleted petroleum or natural gas reservoirs or man made caverns from mining operations. One of the obstacles in using hydrogen as an automotive fuel is storing it safely and efficiently on board vehicles. Although it is possible to store hydrogen as a high pressure gas in steel containers, disadvantages exist because of the weight of the storage containers and the safety hazard in the event of an accident.

In an enclosed space, the vented hydrogen also presents a risk because of hydrogen’s wide flammability limits. Hydrogen explosions are rare, but any combustible gas in an enclosed space can be a safety problem. One solution is to burn off the escaping hydrogen and use this energy for heating or cooling. It can also be used to power a fuel cell. Stationary liquid hydrogen storage tanks that are used in laboratories are able to keep the hydrogen in a liquid state for several months. It should be possible to build vehicular storage tanks that would maintain hydrogen in a liquid state for several weeks.
