5 Alternative Fuels that Will Reenergize the Transportation Industry

The transportation industry relies heavily on diesel to help it successfully transport products from manufacturers to consumers via trucks worldwide. Technology has been instrumental in reducing the number of empty miles driven, and finding an alternative fuel source is the next step for eco-conscious companies.  As concerns about the longevity of fossil fuels grow, the search for a more sustainable fuel is intensifying.

There are more than 222 million licensed drivers in the U.S. today and the amount of fuel needed to power their vehicles is astronomical. The transportation of people and goods accounts for about 25% of all energy consumption worldwide. Gasoline is a byproduct of fossil fuels, of which the earth has a limited supply. The discovery of an alternative to gasoline is vital to preserving our modern way of life and avoid running out of fuel altogether.

Fortunately, scientists and engineers are already tackling this problem. The switch toward alternative forms of fuel is still in its infancy, but researchers are working tirelessly to create cleaner, more sustainable energy sources. Below are just five potential forms of less harmful and more sustainable fuel that have the potential to replace gasoline and introduce a new wave of cleaner, more efficient vehicles:


There are currently three types of electric cars: battery electric vehicles (BEV), plug-in hybrid electric vehicles (PHEV) and hybrid electric vehicles (HEV). According to The Guardian, there are already over 3 million electric and plug-in hybrid cars on the road today. Electric cars are known to be environmentally and economically friendly as they drastically reduce harmful emissions and save users all of the money they would have spent on fuel.

However, electric vehicles are restricted to a specific number of miles they can drive before they need a recharge (the average is about 100 miles). Outside of major cities charging stations are difficult to come by, making electric vehicles less than ideal for lengthier trips. In order for electric trucks to become a viable option for the supply chain, a solution to the limited range needs to be found. Once electric vehicles are able to carry heavy loads for longer stretches of road, the logistics industry will have a new, viable option for shipping.


Ethanol fuel consists of the same alcohol that is in most cocktails. It originates from plant matter including algae, trees and corn. Ethanol fuel is renewable and much better for the environment than gasoline as it produces less carbon dioxide, hydrocarbon and oxides of nitrogen emissions.

The production of ethanol can support farmers and create agricultural job opportunities. Ethanol production can also be domestic, which helps reduce dependence on foreign oil. Gasoline is often blended with a high percentage of ethanol to create a cleaner-burning fuel because of its higher octane levels.

A transition to fuel made only of ethanol would be simpler than other options because newer trucks are consistently manufactured with the ability to burn ethanol-mixed gas and wouldn’t have a problem burning pure ethanol. Since many gas stations are already selling a blend of gas with ethanol in it, potential infrastructure problems are not as likely if the industry ever makes the switch.

The point of concern with transitioning shipping entirely to ethanol fuel is the effect it would have on crop prices. Utilizing crops as fuel rather than as food would drastically increase the price of corn and other produce. In order to have ethanol completely replace gasoline, a significant amount of the world’s forests and free spaces would have to be dedicated to farmland.


Biodiesel is a renewable fuel made from vegetable oils and animal fats and can be used before cooking or recycled even after use in cooking. It is non-toxic, biodegradable and emits less harmful chemicals into the atmosphere. Biodiesel can work in any diesel engine, making for an easy integration into the transportation industry.

Although there are many positives to biodiesel fuel, it still presents its fair share of challenges. For one, it is much less powerful than regular diesel and gasoline fuels. Biodiesel is reportedly 10% weaker than traditionally used fuel types. The storage of biodiesel fuel can also cause some major problems over time. When it’s stationary for an extended period of time, biodiesel tends to thicken which can clog filters and create corrosion.


Hydrogen is a popular and highly innovative alternative to gasoline. Fuel cell vehicles are technically considered electric vehicles, but they rely on a mixture of oxygen and hydrogen to produce electricity rather than a traditional battery. These cars are similar to gasoline and diesel vehicles as they are refueled in the same conventional manner and share the same long-distance driving range, allowing them to drive further and faster than battery-powered electric vehicles.

A vehicle with a fuel cell and electric motor running on hydrogen can be two to three times more efficient than gasoline. These vehicles discharge zero harmful emissions, only water. Hydrogen fuel can be produced domestically from nuclear power, natural gas, biomass and renewable powers like wind and solar energy.

The biggest problem associated with hydrogen fuel is cost. The fuel cells required to power hydrogen-fueled cars are very expensive, and there are very few gas stations that currently offer hydrogen as fuel. Should the transportation industry ever decide to make the switch to hydrogen-powered trucks, the eventual ROI could make it worth it.

Natural Gas

Natural gas is a fossil fuel mostly comprised of methane. This alternative to traditional fuels can be produced domestically and is less expensive than gasoline. Natural gas could cut back on greenhouse gas emissions by 10% as well.

The reason natural gas hasn’t supplanted gasoline as the preferred fuel type is because of the limited number of vehicles on the market with the capability to utilize it. Making trucks natural gas-friendly would be a very costly investment for the trucking industry. There are very few fueling stations that provide natural gas and it provides fewer miles-per-tank than vehicles running on gasoline or diesel.

92% of the U.S. transportation sector uses petroleum products such as gasoline or diesel for fuel. These resources won’t last forever and soon we will have to find a new way to fuel our cars, trucks, boats and airplanes. Our economies are powered by supply chains, and whatever fuel becomes the fuel of choice in the future will have to work for the supply chain industry, not only for personal drivers. While some alternative fuels are already being implemented, research is still being done to develop a fuel that is truly sustainable, efficient, and environmentally friendly.
