The internal combustion engine, whether driven by gasoline or diesel, has dominated the automotive landscape for more than a century.
Its current form, however, does not have an unlimited future because it is still primarily reliant on non-renewable fossil resources.
Due to shifting fuel prices, this model is unsustainable.
The government is also under constant pressure to develop cleaner fuels for cars, and has promised to ban the sale of new gasoline and diesel vehicles by 2030.
As a result, a variety of future fuels have been proposed to replace today's crude oil-fueled engines, all of which have one thing in common: the ability to run on nonrenewable fuels.
Cars' Best Alternative Fuels
Here are nine potential future fuels for your vehicle in the coming decades.
• Biofuel
• Electricity
• Steam
• Kinetic
• Heat
• Hydrogen
• Air
• Nitrogen
• LPG
Let's look at the finest car alternative fuels:
1. Biodiesel
Bioethanol (which can be used instead of gasoline) is made from corn and sugarcane, whereas biodiesel is made from vegetable oils and animal fats.
Both are meant to take the place of nonrenewable crude oil-based fuels.
The greatest biofuels are second-generation biofuels made from sustainable sources rather than those developed for food.
Many individuals believe they are the best medium-term solution for environmentally friendly fuels.
2. Electrical power
The electric car is powered by batteries and driven by a motor, Vehicles like the Nissan LEAF, the UK's best-selling green vehicle, are gaining appeal.
However, because to restricted battery efficiency, most have a maximum range of roughly 100 miles (and takes several hours to recharge).
Electric vehicle batteries are also highly pricey.
When compared to the range of economy batteries available for petrol vehicles, this is a small drawback.
Electric automobiles are now the most commercially available answer, with a wide range of models ranging from £5,000 to £400,000 on the market, with Tesla's Model S acting as a milestone example.
3. Steam Cars
Although steam cars have been present since the nineteenth century, models powered by internal combustion engines have subsequently overtaken them.
Some people believe they can repay the favour now.
They're 'external combustion engines,' which means the gasoline is burned outside of the engine, resulting in lesser emissions.
Several concepts for current high-power steam engines in automobiles have been proposed.
4. Dynamic
Brake energy regeneration systems are found in many electric vehicles (as well as a growing number of internal combustion engine vehicles) and convert braking energy into electric energy.
Such technologies are projected to become more common in the future in order to better harness a car's moving energy and use less gasoline overall.
Why not trade in your current vehicle for a more fuel-efficient model at RAC Cars if you're seeking for a cheaper alternative?
5. Warmth
Heat loses two-thirds of the energy produced by gasoline or fuel. Thermoelectric technology, which transforms heat into power, can help with this, and numerous car manufacturers are already working on it.
One approach that potentially reduce fuel use by 5% is to utilise thermoelectric panels to convert waste exhaust pipe heat into energy.
6. Hydrogen
Hydrogen can be utilised instead of fossil fuels in combustion engines. Hydrogen cars emit only water and have no toxic tailpipe emissions.
Critics contend that it diverts energy away from the hydrogen production plant and that there is currently no hydrogen recharging infrastructure.
BMW, on the other hand, sells hydrogen automobiles and recently stated that new hydrogen vehicles "will be marketed in the United Kingdom."
Hydrogen can also be used to power a fuel cell to generate electricity.
It is usually considered to be one of the greatest long-term energy sources for automobiles because it produces no pollutants and overcomes the limits of onboard batteries.
Fuel cell technology, on the other hand, is currently prohibitively expensive.
7. Compressed air
Compressed air can be used instead of gasoline to drive pistons and generate power in a combustion engine.
When held in 4500psi tanks, air has a substantially lower energy density, yet it creates no exhaust emissions.
Over the years, several concepts have been offered, and some car manufacturers, such as Tata, have even proposed mainstream air-powered vehicles.
8. Nitrous oxide
Heating liquid nitrogen kept in a pressurised tank produces high-pressure gas. Both a piston and a rotary engine can be powered by it.
Liquid nitrogen, on the other hand, is a less effective energy carrier than fossil fuels, and its production necessitates the use of electricity.
9. LPG Gas
LPG stands for liquefied petroleum gas, a sort of 'liquid gas' that can be used to power a variety of devices, including automobiles.
It was once purposefully burned and wasted, but it is now recognised as a versatile low-carbon fuel that can be put to good use.
LPG is only used to fuel less than 1% of cars on UK roads, despite its extensive use in homes and businesses.
According to UKLPG, the UK trade group for the LPG industry, there are roughly 1,400 LPG refuelling stations across the country, compared to approximately 8,500 filling stations altogether.
