E-fuels: All types of fuel in liquid or gas form produced from renewable or decarbonized electricity are called e-fuels. Like e-methane, e-kerosene, e-methanol are called e-fuels.
The journey is becoming very expensive due to the expensive petrol-diesel. On the other hand, they are also causing air pollution. Both the issues are very important for any country or government. Because it is directly affecting the pockets of common people as well as health. In such a situation, e-fuels are becoming the first choice as its alternative. Work on e-fuel is progressing rapidly all over the world. It is also getting success to a great extent. Talking about India, the government is promoting ethanol fuel (e-fuel) a lot. At present, more than 10% of the use of ethanol (ethanol fuel price) is being done in the country. The government has set a target of 20% by 2025. In such a situation, we need to understand what is e-fuel?

What is E-fuel?
E-fuels, or electrofuels, are synthetic fuels that are produced using renewable energy sources, such as wind, solar, or hydroelectric power. The basic idea behind e-fuels is to use electricity from these renewable sources to create a fuel that can be used in existing internal combustion engines, without requiring any modifications to the engines themselves.
The production of e-fuels typically involves the electrolysis of water to produce hydrogen, which is then combined with carbon dioxide to create a liquid or gaseous fuel. The carbon dioxide used in the process can be captured from the atmosphere or from industrial processes, which helps to reduce greenhouse gas emissions.
One potential advantage of e-fuels is that they can be used in existing infrastructure, such as pipelines and gas stations, without requiring significant changes. This could make them a more practical alternative to electric vehicles, which require significant investments in charging infrastructure.
However, e-fuels also have some significant drawbacks. They are currently more expensive to produce than fossil fuels, and require large amounts of renewable energy to produce. Additionally, they may not be as efficient as other renewable energy technologies, such as batteries or hydrogen fuel cells.
Overall, e-fuels are an interesting technology with the potential to play a role in the transition to a low-carbon economy. However, their cost and efficiency will need to improve significantly in order for them to be a competitive alternative to other forms of renewable energy and transportation technologies.
Gas e-fuels: includes liquid H2 generated from renewable hydrogen and e-GNL generated from e-methane.
Liquid e-fuels: This includes e-fuels such as e-methanol and e-crude, also known as synthetic crude oil. These are produced from e-kerosene and e-diesel.
Gas or Liquid Form: Synthetic Ammonia
E-fuel is very important for climate. The production of synthetic e-fuel has taken many years. Its use is being greatly encouraged all over the world. Because they do not affect the climate. In India too, a lot of work is being done in this regard. Prime Minister Narendra Modi (PM Modi) had said in the 26th United Nations Climate Change Conference (COP-26) in June that India will become Zero Carbon Emission by 2070. For this, an investment of 10000 billion dollars has also been talked about.
Preparations for e-fuel at the global level
Worldwide, a lot of work is being done for e-fuel in the direction of reducing carbon emissions. In this direction, the world's first commercial e-fuel plant is being built in southern Chile. Experts believe that in the coming days, fuel will be made by mixing electricity, water and air almost everywhere in the world. Because geopolitics tension has a great impact on the prices of Crude Price and Natural Gas, due to which the common people have to bear the brunt. Along with this, it also affects economic growth.
Use of E-fuel in India
In India, the use of ethanol has increased in vehicles as well as in planes. Fuel is being prepared by extracting ethanol from spoiled food grains like sugarcane and wheat, broken rice, agricultural residues. This will reduce the pollution coming out of vehicles. Actually, India is adopting the pattern of Brazil and America in this direction. Since e-fuel is better for the engine than petrol-diesel. Because it increases the life of the engine. This can increase its demand among the common people. However, the cost of e-fuel is quite high as compared to others.
How is e-fuel prepared?
According to science, e-fuel is a type of hydrocarbon (i.e. which is made up of hydrogen and carbon) and to use it as a renewable energy, hydrogen and oxygen are separated with the help of water. The hydrogen is then later separated from the carbon dioxide. When it filters out from the air in the process, it turns into methanol. It is then converted into gasoline with the help of ExxonMobil licensed technology. This is called e-fuel.
How many types of E-fuel are there?
There are two types of e-fuel. One is gas e-fuel and the other is liquid e-fuel. (Keep these things in mind to buy scooty at low cost) In gas e-fuel, liquid H2 generated from renewable hydrogen and generated from methane gas There are e-GNLs. In addition, liquid e-fuel consists of methanol and e-crude.
Benefit of using E- fuels
There are several potential benefits of e-fuels:
1. Carbon neutrality:
E-fuels have the potential to be carbon-neutral, meaning that they don't contribute to greenhouse gas emissions that cause climate change. The carbon dioxide that is released when e-fuels are burned is offset by the carbon dioxide that was captured during their production, so the net emissions are zero.
2. Compatibility with existing infrastructure:
E-fuels can be used in existing infrastructure, such as gas stations and pipelines, without requiring significant modifications. This could make them a more practical alternative to other low-carbon technologies, which often require new infrastructure to be built.
3. Energy storage:
E-fuels can potentially be used as a form of energy storage, since they can be produced using excess renewable energy and stored until they are needed. This could help to address the problem of intermittent renewable energy sources, such as wind and solar power, which can't always produce energy when it is needed.
4. Decarbonizing hard-to-electrify sectors:
E-fuels can potentially be used to decarbonize sectors that are difficult to electrify, such as aviation and shipping. These sectors require high-energy-density fuels, which are difficult to provide using battery technology alone.
5. Reduced dependence on fossil fuels:
E-fuels can help to reduce dependence on fossil fuels, which are a finite resource and contribute to climate change. By using renewable energy to produce e-fuels, we can create a more sustainable energy system.
Overall, e-fuels are an interesting technology with the potential to play a role in the transition to a low-carbon economy. However, their benefits will need to be weighed against their cost and efficiency, as well as their impact on the environment and energy systems.
Where is E-fuel being used the most?
Although the use of e-fuel is slowly starting all over the world, but e-fuel is being used the most in Brazil. The main reason for this is also believed that they have three times more land than India. Apart from this, vehicles are also running on e-fuel in Sweden and Canada. In Canada, subsidy is also being given by the government on the use of ethanol.
