With the automotive industry's impact on the environment and soaring gas prices, drivers are increasingly considering alternative fuels. While gasoline and diesel are still the most popular, alternative fuels like hydrogen, electricity, ethanol, and natural gas are becoming more common. Many alternative-fuel vehicles, such as hybrids, can use gasoline, but is it possible for alternative-fuel vehicles to run on gasoline alone?
Can a car with alternative fuel drive on gasoline?
| Characteristics | Values |
|---|---|
| Can a car with alternative fuel drive on gasoline? | Yes, gasoline cars can be retrofitted to LPG (liquefied petroleum gas) or Autogas and become bifuel vehicles, allowing drivers to switch between LPG and gasoline during operation. |
| Types of alternative fuels | Hydrogen, LPG, CNG (compressed natural gas), ethanol, biodiesel, electricity, compressed air |
| Hydrogen | Hydrogen can fuel two types of cars: fuel cell vehicles and vehicles with an internal combustion engine engineered to use hydrogen instead of gasoline. |
| LPG | LPG is a low-pressure liquefied gas mixture composed mainly of propane and butane, which burns in conventional gasoline combustion engines with less CO2 than gasoline. |
| CNG | CNG is high-pressure compressed natural gas, mainly composed of methane, that is used to fuel normal combustion engines instead of gasoline. CNG combustion produces the least amount of CO2 of all fossil fuels. |
| Ethanol | Ethanol is an alcohol-based fuel made from renewable materials like crops (corn, barley, wheat, sugar cane). It is often added to gasoline in the summertime to help cut emissions. E10 (10% ethanol and 90% gasoline) is the most common blend, but E85 (15% gasoline and 85% ethanol) is also available for flex-fuel engines. |
| Biodiesel | Biodiesel is a byproduct of biodegradable, non-toxic resources like vegetable oils, animal fats, and recycled restaurant grease. It comes in blends (e.g., B5) and pure form (B100). Biodiesel-powered vehicles emit CO2, but this is offset by the CO2 absorbed by the feedstock crops. |
| Electricity | Electric cars use electric motors and batteries, offering a cleaner alternative with zero tailpipe emissions. Plug-in hybrids (PHEVs) have larger batteries and can run on electricity alone for limited distances. |
| Compressed air | Compressed air can replace gasoline or diesel in combustion engines, driving the pistons and producing power. Cars using compressed air have electric motors to compress air into high-pressure tubes, but they are not considered fully electric as the motors don't directly power the wheels. |

Hydrogen-powered cars
HFCVs can be divided into two types: fuel-cell vehicles and vehicles with internal combustion engines engineered to use hydrogen instead of gasoline. In fuel-cell vehicles, the hydrogen and oxygen combine in a chemical process within the fuel cell to create electricity, powering the electric motors. This type of vehicle is considered a series hybrid, or fuel-cell hybrid electric vehicle (FCHEV), as it combines characteristics of both electric and hydrogen power.
The other type of HFCV, a hydrogen combustion engine vehicle, uses an internal combustion engine similar to a gasoline-powered car but with hydrogen as the fuel source. This variation is less common, as most HFCVs focus on utilising hydrogen's zero-emission potential through the fuel-cell system.
The driving experience of an HFCV is comparable to that of an EV, although HFCVs may struggle with acceleration due to the steady power output of hydrogen fuel cells. To address this, some manufacturers include a supplementary battery to assist with acceleration and other high-power demands.
As of mid-2022, there were approximately 17,000 hydrogen-powered vehicles on US roads, all located in California, which is the only state with a comprehensive network of retail hydrogen fuelling stations. The limited availability of fuelling infrastructure and the relatively low number of vehicles currently in operation pose challenges to the widespread adoption of hydrogen-powered cars. However, companies like Toyota, with its Mirai model, remain committed to promoting hydrogen power as an alternative to battery-electric vehicles.

Electric vehicles
Battery technology is improving steadily, and EVs are becoming more affordable. Charging networks have grown across the country, making both daily driving and long-distance travel in EVs feasible. However, they are far from perfect. If you're thinking of purchasing an EV, here are some things you should know:
Charging
It takes roughly 10 hours to fully charge a drained 60-kilowatt-hour (kWh) EV battery with a Level 2 240-volt charger. Your EV likely comes with a Level 1 120V charger, which may take almost 40 hours to charge the same battery. The actual time depends on several factors, including battery size, the max charging rate of the onboard charger, battery level, and the speed and power level of the charger.
Range
The range of an EV depends on several factors, including speed, payload, tires, driving conditions, and HVAC usage. The faster you go, the more the electric motor works, drawing down the battery. More weight (passengers and cargo) places a larger load on the motor. Low air pressure and worn tires reduce traction, lowering miles per charge. Stop-and-go driving, hard acceleration, extreme temperatures, and severe weather conditions also affect range. Running the air conditioning, heater, defroster, or heated steering wheel will quickly drain the battery.
Battery Degradation
An EV's battery slowly loses capacity as it ages. New EV lithium-ion batteries may last 12 to 15 years in moderate climates. In reality, EV batteries should outlast the life of the vehicle. Fast-charging on a Level 3 connection causes more heat buildup and degrades batteries faster than a Level 2 connection. Charging the battery above 80% or letting it dip below 20% also causes more wear and reduces battery life.
Cost
The average EV cost $65,291 in September 2022, almost $17,000 more than a comparable internal combustion engine (ICE) vehicle. However, EVs require less basic maintenance, such as oil changes and other engine services, which can save owners $1,300 a year compared to a midsize ICE vehicle driven 15,000 miles a year. Many new EVs also qualify for federal tax incentives of up to $7,500. Additionally, electricity typically costs less than fossil fuels, decreasing the overall cost of EV ownership.

Gas-electric hybrids
Hybrid vehicles come in many forms, from cars to pickup trucks, SUVs, minivans, and even sports cars. They combine a gasoline engine with one or more electric motors, with power coming from a traction battery pack. This combination can be used to increase fuel efficiency or performance.
A conventional hybrid is fuelled with gasoline, while a plug-in hybrid uses both gasoline and electricity and can be plugged in to charge the battery. A hybrid does not need to be plugged in—its battery is charged through regenerative braking and by the internal combustion engine. The electric motor can allow for a smaller engine, improving fuel economy without sacrificing performance.
A plug-in hybrid electric vehicle (PHEV) can be plugged in and will run on electricity for 20 to 40 miles before the gas engine kicks in, extending the range for an additional 300 to 500 miles. An electric vehicle (EV) runs solely on electricity and has no tailpipe emissions.
The world of alternative fuels is diverse and includes compressed air cars, ethanol, hydrogen fuel-cell vehicles, and natural gas vehicles. Compressed air cars use the expansion of air in high-pressure tubes to drive the engine's pistons, with electric motors on board to compress the air. Ethanol is often added to gasoline in the summertime to cut emissions and can also be used in flex-fuel engines that run on either standard gasoline or E85 ethanol. Hydrogen fuel-cell vehicles use a hydrogen fuel cell to generate electricity, with water vapour as the only byproduct. Natural gas vehicles (NGVs) run on high-pressure compressed natural gas (CNG), which is mainly composed of methane and produces less CO2 than gasoline.

Compressed air cars
A compressed-air car is a vehicle powered by pressure vessels filled with compressed air. The expansion of the compressed air as it is released from high-pressure tubes drives the engine's pistons. The car may be powered solely by air or combined with other fuels such as gasoline, diesel, or an electric plant with regenerative braking.
Compressed-air cars are emission-free and do not require a connection to the electric grid. They can be powered by a wind turbine or other renewable energy sources, which directly drive an air compressor or hydraulic pump. The materials used to make them can be almost entirely eco-friendly and recyclable, and they do not have messy batteries or tailpipe scum. The factory making them is the only possible source of pollution. Another advantage of compressed air cars is their air-conditioning system, which uses a heat exchanger on the air tanks to provide free air conditioning without the need for hazardous refrigerants or complicated compressors.
Despite these challenges, there is ongoing development in the field of compressed air vehicles. Zero Pollution Motors (ZPM) plans to produce the first compressed air-powered car for sale in the United States by mid-2024, with earlier production scheduled for Europe. The AIRPod vehicle, developed by MDI, is a small, affordable, zero-pollution car with a futuristic design, marking a turning point in urban mobility. Tata, an Indian automotive company, has also partnered with MDI to develop an air-powered car.

Natural gas vehicles
CNG vehicles store natural gas in tanks under pressure, while LNG is stored as a liquid, giving it greater energy density than CNG. The driving range of NGVs is generally less than that of comparable diesel or gasoline vehicles due to the lower energy density of natural gas. However, extra storage tanks can be added to increase the range, although this additional weight may reduce cargo capacity.
NGVs are popular in regions or countries where natural gas is abundant and where there are tax incentives for natural gas-powered vehicles. As of 2017, there were 24.5 million natural gas vehicles worldwide, with China, Iran, India, Pakistan, Argentina, and Brazil leading the way. In Latin America, almost 90% of NGVs have bi-fuel engines, allowing them to run on either gasoline or CNG.
Gasoline cars can be retrofitted to become bifuel NGVs, allowing the driver to switch between CNG and gasoline during operation. Dedicated NGVs, on the other hand, are designed to run only on natural gas, while dual-fuel NGVs use natural gas but require diesel fuel for ignition assistance.
