Conclusion
If one is looking for an electric-powered vehicle with no emissions, a hydrogen car might be a good option. However, there is currently considerable risk involved. The fuel is more expensive than gasoline, and building a new fuelling network from scratch has proven far more difficult and unreliable than automakers had anticipated.
If the hydrogen fuel isn't supplied at 10,000 psi, a hydrogen vehicle becomes non-functional. Electric passenger cars are likely to be more popular in the future. However, as both these options are costly, we should look into car insurance options before considering any of these two.
