The first lead is hybrids, cars that combine energy from an electrical motor and a combustion engine to move. Although they consume less compared to normal cars, they still require the same depleting fuel to move and generate electricity for their batteries. The second take is pure electric cars. Such cars have large lithium batteries, which provided power to the vehicle’s electric motor. However, this particular technology has a huge problem. It takes longer to fully charge the electric car batteries compared to filling up the tank with petrol.

Hydrogen gas canbe generated using a wide range of natural resources and man-made by products such as sewage sludge. It can also be created from water using natural renewable energy sources like solar and wind power. When compressed, it has a higher energy density than batteries, and is relatively easy to store and transport, therefore it also carries expectations for potential future use in power generation and a wide range of other applications. The Toyota Mirai is one example of what are now known as Fuel Cell Vehicles (FCV). The name Mirai means future in Japanese.
