New Delhi. Union Transport Minister Nitin Gadkari had said that he is trying to show people that it is possible to run vehicles on green i.e. green hydrogen without releasing toxic gases. Even India is ready for the National Hydrogen Mission for the production of this clean energy. Know about this in 5 Point Explainer (5-Points Explainer) ..
1.What is Hydrogen and how is it helpful?
Hydrogen is the fuel of stars, it contains a lot of energy. It is found in abundance in the universe. But on Earth it is found in the form of complex molecules such as water or hydrocarbons. Hydrogen is not a source of energy like any fossil fuel or renewable energy source, such as sunlight and wind. Rather it is a carrier of energy. That is, it can be produced for use, it can be separated or stored. No matter how it can be used, water is formed when it burns. The World Energy Council says that the energy obtained by burning one kilo of hydrogen is three times more than the burning energy of one kilo of gasoline. After this water is made. Then there is the hydrogen fuel cell which is a type of electrochemical cell that converts the chemical energy of hydrogen and water into electricity. The waste that remains from this is water. A fuel cell can produce energy as long as it is getting a supply of hydrogen and water.
2. How many colors of hydrogen?
There are many ways to separate hydrogen, due to these methods, its color gets different. According to the World Energy Council, 96% of hydrogen is produced from fossil fuels. The hydrogen released during this is called gray or gray hydrogen. However, this process is not as expensive as others. But a lot of carbon dioxide is released in it. That is why when carbon dioxide is stopped from being released through the Carbon Capture and Storage (CCS) process, this hydrogen turns from gray to blue i.e. blue hydrogen. But this process is very expensive.
Apart from this, there is another color of Hydrogen, Turquoise. In its production gas is produced through the process of methane pyrolysis. in which solid carbon is produced. But this type of production is still in the experimental stage. Similarly pink hydrogen is produced by the electrolysis process of water. The only difference is that atomic energy is used in it. Similarly, when hydrogen is made using solar energy, it is called yellow hydrogen.
3. What is Green Hydrogen, How Beneficial?
Green Hydrogen is what the government is working for. It can be obtained from any kind of renewable energy, Green Hydrogen can be obtained through electrolysis of energy from renewable energy sources. However, its process is very expensive and it has not yet been started on a commercial scale. Green Hydrogen is a fuel that has zero carbon emissions. Meaning no matter how much you burn it, it will not cause pollution.
4. What is the government doing for Green Hydrogen?
On August 2021, Prime Minister Narendra Modi announced the NHM (National Hydrogen Mission), which aims to make India a global hub of Green Hydrogen. In a program in April this year, the then Petroleum Minister Dharmendra Pradhan had also said that hydrogen fuel has attracted policy makers only to curb carbon emissions. However, there is still a lot of expansion to be done in NHM. The ministry has told that several pilot projects are going on in this regard, under which 50 buses in Delhi are being run by mixing hydrogen with CNG. There is a plan to implement it in the whole country.
5. There is still a challenge in the use of hydrogen energy
Technological development for the production of Green Hydrogen will cost a lot. But the fall in the prices of renewable energy and fuel cells has increased the enthusiasm for investment in this sector. Reports suggest that this year the Center has approved a pilot project for research and development at a cost of Rs 800 crore between 2021 and 2024. Along with this, now private companies are also being encouraged to invest in it. At present 14 projects are going on.
