Some automakers love the idea while some despise it, so let's take a step back and work our way up. 🚙 engineering
and reducing the carbon footprint. This is because no carbon compounds are released as byproducts when these vehicles run on hydrogen.Because hydrogen has a low volumetric energy density, it needs to be stored as a compressed gas in order to give the driving range of conventional vehicles. This requires a the use of high-pressure tanks capable of storing hydrogen at either 5,000 or 10,000 pounds per square inch .
Currently, the majority of hydrogen is extracted using steam reforming, which combines high-temperature steam with natural gas to extract hydrogen.water using electrolysis. This is more energy intensive, but can be done using renewable energy, which would eliminate a great deal of the emissions. However, the cost of producing hydrogen is still higher than that of gasoline , so will need to come down quite a bit before hydrogen engines can be cost-effective on a large scale.
