With oil production declining and air pollution, car manufacturers are looking to alternative fuels. But what will power the automobiles in future?
Fly into any major city all over the world and you’ll be greeted with a familiar sight: sheen of brown smog that floats over town. This smog comes mainly from automobiles. It brings carbon dioxide, the gas that’s principally accountable for climate change.
Authorities have been caused by the steady increase in pollution all over the world to create laws which will restrict the volume of greenhouse gasses that we can place into the atmosphere.
Many countries, including the USA, have mentioned energy autonomy as well as reducing pollution. Which is, having the ability to create energy, particularly renewable energy without needing to rely on imported petroleum either from unstable areas of the world or from regimes deemed unfriendly.
Do not worry, the automobile will not vanish. As you read, today’s scientists are studying the fuels of tomorrow. Many scientists believe that the hydrogen will be the fuel of future.
Hydrogen is being used in a variety of applications, including the production of household products like toothpaste and blasting rockets into space. Now, hydrogen is about to find its way into the family car after decades of development.
Advantages of hydrogen:-
Refuels faster than electric cars
More energy-rich per kilogram than petrol or battery-powered electric cars
Produces only water as exhaust
Disadvantages of hydrogen:-
Incompatible with current infrastructure
Difficult to store and transport
Very expensive to produce
High prices and difficulties with storage mean that a lot must be done to make hydrogen the fuel of the future although it is an incredibly promising fuel.
Hydrogen is a perfect fuel. The truth is, when scientists actually wanted a fuel that would go the distance, they turned to hydrogen to produce electricity on NASA’s Apollo missions — hydrogen was used as a propellant for the Saturn V rockets, while hydrogen fuel cells were used to power the electronic equipment inside the command modules — including the Apollo 11 mission that landed the first people on the moon in 1969.
As hydrogen is gasoline under standard conditions, it is usually compressed under high pressure, likewise to the liquid petroleum gas (LPG) that is popular in Aussie cabs and other high mileage vehicles. Hydrogen fuel cells are rather another animal while cabs combust LPG instead of petrol in an ordinary internal combustion engine.
They may be really fairly much like batteries, while fuel cells may seem fancy. Like batteries, fuel cells produce electricity, meaning that any automobile that runs off a fuel cell is really an electric car. Additionally like batteries, fuel cells combine two compounds that react to generate an electric current.
On the other hand, the significant difference with fuel cells is that, unlike batteries, energy is not stored by them. Instead, they’ve their “fuel” fed right into the battery “cell”, hence the term fuel cell. To simplify matters, think as batteries that eat out, rather than bring their lunch of fuel cells.
There are a number of scientists who claim that gasoline or electricity will be the fuel of future but the majority believes that hydrogen is the only element that can be the better replacement.
