Hydrogen based cars are the future of the automotive industry. They are better for the environment, more efficient, more powerful, and use an energy source that is renewable and readily available. Given the global environmental catastrophe that the world no face, to itch to a fuel source that does not negatively affect the environment is necessary.

Compared to petrol and electric based automotives, cars that rely on hydrogen-based fuel cells are way better for the environment. This is due to hydrogen fuel cells not generating greenhouse gas emissions when driven like petrol cars which use fossil fuels to run, instead producing only water and warm air resulting in reduced pollution as well as improving the air quality. According to the US environmental protection agency a typical petrol-based passenger vehicle releases 4.6 metric tons of carbon dioxide per year while hydrogen-based vehicles don’t produce any carbon dioxide. Although electric battery powered cars don’t produce harmful substances much like hydrogen-based cars, as of now they have a reliance on lithium tech for their batteries which are bad for the environment. Lithium-ion batteries are very harmful when being produced and are also very toxic and may leak while in landfill which could reach water supplies and ecosystems.

Hydrogen is also a renewable and readily available source of energy with hydrogen being the most abundant element in the universe. This means compared to petrol, which will run out at some point, hydrogen will last us a long time and be a fuel source we can always rely upon. Hydrogen based fuel cells are also more powerful and energy efficient then vehicles that use fossil fuels. Hydrogen fuel cells are a high density and efficient fuel source having the highest energy content of any common fuel by weight. For example, an average combustion-based power plant generates electricity at 33-35% efficiency compared to hydrogen fuel cells which generate electricity at 65% efficiency. Another upside to the use of hydrogen-based fuel cells is the fast rate of charging, where much like a regular combustion-based engine it can be refuelled and ready to go in no time only taking 5 mins to charge, unlike electric vehicle which can take 30 mins to several hours to get back up to max charge. 

Although hydrogen powered vehicles have downsides the good far outweighs the bad, and with the support of automotive companies trying to make hydrogen-based fuel cells the best it can be its safe to say that hydrogen powered cars are the future of automotives being a cleaner more efficient energy source and can be expected to be seen more in the future when more companies follow in Porsches footsteps and join the fight for producing cleaner more efficient engines in cars.
