It’s been a long road for fuel cell cars to get to where they are now, a possible option. It all started back in the 1980s when fuel-cells themselves had to be physically shrunk to fit into a normal car, not the back of a van. Then they had to make them affordable and the fuel able to be widely available. All of these obstacles have been overcome yet fuel cell cars still have not been mass adopted.
That is because they were not found to be very efficient. To produce the gas, compress it, and transport it is costly. However, there is a special little fuel cell car called Rasa that is drastically more economical and its creator has come up with a more efficient hydrogen distribution system too. The car and the system around are both part of a grand plan by the company Riversimple, founded by Hugo Spowers, former motor racer and mechanical engineer of race cars.
