Hydrogen as a fuel is generating a lot of interest in the automotive sector, which is looking for greener and cleaner energy alternatives to power future automobiles. Several automakers are developing hydrogen fuel cell technology for car power, however
Green hydrogen is said to be the most carbon-free energy a vehicle can use. While lithium-ion batteries are also made in a way that releases carbon into the atmosphere, green hydrogen does not have this problem. The only thing that comes out of the exhaust when it's used as fuel is water. The vastness of hydrogen energy generation, on the other hand, is something that automakers see as a roadblock to the development of hydrogen-powered automobiles. The scarcity of hydrogen is also a source of concern.
Another advantage of hydrogen energy is that it takes less time to refuel or charge than lithium-ion-powered electric vehicles. In hydrogen vehicles, the battery packs are also substantially smaller. Aside from that, the hydrogen fuel cell saves rare metals like nickel and cobalt, which are needed in the creation of traditional lithium-ion batteries. In general, hydrogen is seen as a viable alternative to lithium-ion batteries in electric vehicles.
