Over time, we need a way to reduce carbon dioxide emissions, to reduce global warming, in today's time and for the next 30 years. To meet this challenge, sustainable sources must be found that do not produce any carbon emissions when burning, such as hydrogen, which is one of the most abundant on the Earth's surface. Hydrogen is neither color nor smell and is also non-toxic, and can be used as fuel for cars instead of gasoline and diesel.
How does hydrogen work?
Hydrogen is an ideal alternative to achieving these goals. Cars that essentially burn liquid fuels to power the vehicle, which produce harmful gases, that increase global warming. They can be simply replaced by hydrogen cars, which can be filled into an in-car tube of the gas station,
so that the fuel cell in an electrochemical process integrates hydrogen with air oxygen, to produce electricity, engine operation and drive the wheels of the car, and water vapor is the only byproduct of this clean, environmentally friendly process.
Hydrogen Types:
Hydrogen is a type, or specifically, colour, albeit an invisible gas: green does not produce carbon emissions, blue produces natural gas, and black is a coal and oil plant. Japan adopts this type of gas and has recently announced that Australia will produce it.
There is also grey hydrogen that is extracted from natural gas, methane and emits in the atmosphere, as well as pink or red that is made through nuclear-powered electrolysis. This is in addition to turquoise extracted through methane pyrolysis process to produce hydrogen and solid carbon. There is also yellow that is manufactured through electrolysis using solar energy.
White is a natural geological hydrogen found in underground sediments. There are no strategies for exploiting this hydrogen at present.
"At the beginning of Africa, we need a framework that allows us to adopt technology that empowers us to use hydrogen," says Happy Camboli, Climate and Energy Advisor-Business Unit South Africa for the BBC. We are pushing for protectionism and infrastructure that allows us to adopt this clean energy locally, not just export it. "
Hydrogen Features:
Hydrogen-powered cars are characterized as producing no harmful emissions, and the only emission that results from this reaction is water vapor only.
In addition, hydrogen is much lighter than air, allowing it to spread rapidly, reducing the risk of explosions.
Energy from one kilogram of hydrogen is more than two times the energy from gasoline, which is polluting to the environment.
In addition to the speed of filling the hydrogen car, you can refuel in five minutes, for a distance of 500 kilometers!.
Hydrogen Fuel Future:
According to the U.S. Department of Energy, an estimated 10 million metric tons of hydrogen are produced annually in the United States, mostly using natural gas in a process called natural gas remodeling.
The hydrogen produced from the power-powered water dismantling process generated on renewable energy sources carries many economic and environmental benefits and is a clean technique for obtaining hydrogen fuels, but it needs electricity.
Researchers estimate that nearly 100 wind farms in the United States are ready to directly connect to water electrolysis systems, providing the possibility of using wind energy at night to dismantle water and produce clean hydrogen fuels.
Hydrogen has always been considered the fuel of the future, as it is a clean fuel whose burning does not produce environmentally damaging gases because it does not produce carbon dioxide, but rather oxidizes into water vapour, making it environmentally safe and possessing high energy.
By 2023, the global hydrogen market is expected to reach about $200 billion, and potential "clean" hydrogen energy markets include everything that depends on its operation on fuel, ranging from energy grid management to automotive fuel cells.
