Are Hydrogen Powered Vehicles Such A Great Idea?
Hydrogen cars have been in the works since the late 1970s. There’s a reason for that. Unlike fossil fuels, there is a never-ending supply of hydrogen and the only exhaust emission is environment-friendly water vapor. While there were original concerns about nitrogen oxides being emitted, proper engine timing and optimized hydrogen concentrations were found to minimize or even eliminate the formation of nitrogen oxides, which cause acid rain and contribute to global warming, among other things. Currently there are two approaches to hydrogen cars: using hydrogen with fuel cells or with a modified internal combustion engine. Hydrogen cars that use both hydrogen and gasoline have two separate tanks that the driver can switch between easily. Nowadays having dual tanks, at least in the US, is a must as hydrogen refueling stops are still uncommon. Indeed, there are little more than 100 in the entire United States. This allows the car to run on regular fuel as needed. Not very “green”, but pra
