Lower operating costs. Better efficiency. No harmful emissions when in use. The disadvantages of using a hydrogen car includes: The vehicle range is limited and it will be difficult to find hydrogen cars for sale in Wellington. It takes longer to fill the tank than an electric battery. Hydrogen cars are more expensive than regular gas-powered vehicles. People don't like that there aren't many places where you can get fuel for them yet either. They do not have as many charging stations around so they will need batteries in order to charge while driving or else they won't be able to go very far before needing a recharge which could take up some time if they're on their way somewhere important. In addition to this, there still needs to be further research done into how safe these types of vehicles really are, because at the moment people aren't quite sure what could go wrong with this technology and whether it could have any long-term effects on the environment or not. There may also not be mechanics who are experienced in handling such car repairs in Wellington. Until more research has been done into these new types of vehicles, they will continue to be quite expensive and many people won't want to invest in them yet, because it could end up being a waste of money if something goes wrong with their vehicle along the way. For now, hydrogen cars are better suited for commercial use rather than personal use as there aren't really any benefits that make using one over an ordinary gas-powered car or electric vehicle, apart from how clean they may seem compared to some other options out there right now.
