Electric cars have become very popular over the past decade. Climate change risk and rising fuel prices have led to significant growth in the electric and hybrid automotive industry, which is certainly supportive of emissions, but vice versa in terms of energy sources.

The electricity used to charge most electric and hybrid cars often comes from non-renewable resources, and other renewable fuels are now being considered for future cars. So what kind of fuels can we see in the near future?

1. The sun

The car above may look like another world but do not be afraid, it is an example! Developers are now working on solar-powered cars that can efficiently absorb enough solar energy for travel. And, fortunately, most of the solar cars that are currently operating look like cars rather than flying saucers.

A.D. Founded in August 2021, 2016, Lighter, a Dutch automobile manufacturer, released one year of light for a solar powered vehicle. The vehicle can travel up to 450 miles per charge, thank you, it looks like the traditional cars you see on the road today.

Although the Lightyear One is indeed a big step towards normalizing solar-powered vehicles, the price point is quite different. Lightyear One currently costs around $ 150,000, far more than most people spend on cars. But like most technologies, the price of such vehicles has to be reduced from time to time.

2. Steam

Steam is a major source of renewable energy, as water is continuously produced in the atmosphere. Unlike other fuels mentioned here, steam was first used to drive cars hundreds of years ago. However, with the advent of the small commercial combustion engine, steam engines began to lose their popularity.

But with the advent of technology, steam engines can certainly come back. American company Cyclon Power Technologies is revolutionizing its steam engine and producing its own hurricane engine.

This engine, called the Schoell Eye, allows steam to be produced by heating and cooling water in a closed cycle. It burns heat by burning elements, but do not worry, such engines can burn renewable biofuels, which are environmentally friendly.

According to the company, their energy efficiency is more conducive to eco-production than conventional diesel or gasoline engines, which, if true, could lead us in the right direction in terms of caring for our environment.

3. Hydrogen

Hydrogen is the most abundant element in the universe. It plays a vital role in the water, in the air, and in living things. It can also be an excellent fossil fuel replacement in a car!

You may have heard about hydrogen fuel cells before. They are usually used for both portable and backup power access. The process itself is a bit scientific, but basically the anode and cathode divide hydrogen atoms into protons and electrons, and the latter can be used to generate electricity.

They are producing hydrogen-powered cars, including the Toyota Miray model below. The Mirai was originally the first hydrogen Toyota released in 2015.

However, like most alternative gasoline cars, myriad is not cheap. While not as expensive as the Lightyear One, it still comes with a new $ 67,000 (similar to some Tesla models). But that price could see a decline in the coming years.

4. Nitrogen

Nitrogen already has a myriad of industrial uses, but nitrogen can ignite the engine. In fact, at the end of the nineteenth century, there was a desire to use liquid nitrogen as fuel after it was first compressed into a form of gas. This liquid involves heating nitrogen to pressure gas, heating the piston or rotary engine.

There are currently no fully nitrogen-powered vehicles on the market, but liquid nitrogen engines are still being developed for this purpose. A specific model known as the Derman motor was introduced in the 1970s by the British inventor Peter Derman. Now Derman’s son is realizing his father’s idea.

However, not everything is smooth here. High levels of nitrogen in the atmosphere are involved in many environmental issues, including the production of toxic ammonia. Therefore, in order for liquid nitrogen engines to expand, scientists must find a way to avoid such hazards.

5. Biodegradable

Biodiesel and traditional diesel are two very different animals. Diesel is responsible for the emission of greenhouse gases, but biodiesel is derived from plants. A gallon produces four times less carbon than carbon dioxide.

So, exactly how is it made? Come on in, take a look and enjoy yourself! Oil, animal fats, and yolks can all be converted to biodiesel (and glycerin as a by-product) in a process called transfusion. Glycerin is separated from oil and grease to produce this alternative fuel.

However, biodiesel is not working properly as a permanent substitute for traditional fuels. It still produces carbohydrates (CO2) and must be made up of plant and animal nutrients, which, if the demand increases dramatically, will further damage the environment. But it is a great short-term solution for oil and gas as scientists and engineers produce other fuels and make them more accessible to the average person.

The future is bright for eco-friendly transport.

Gasoline and diesel cars now take over most of the vehicles on the road and damage our environment every day. But if all goes well with innovation and development, we will soon see a big shift toward alternative fuels.
