What Are eFuels? 4 Modern Use Cases of Electrofuels

As more people grasp the urgency of the world’s climate crisis, innovators are pushing the boundaries of energy production to create cleaner, greener power sources. One such innovation is electrofuels—also known as eFuels or synthetic fuels. eFuels are fuel alternatives that mimic fossil fuels without adding additional carbon emissions to the atmosphere.

So what are eFuels, and how can we use them to power the world without sacrificing climate health? This guide will introduce you to eFuels, describe some advantages, and explore a few prime opportunities for widespread integration.

What Are eFuels?

Electrofuels are traditional fuel alternatives that can replace fossil fuels. eFuels are usually made from captured carbon dioxide (or carbon monoxide) and can significantly decrease the emissions profile of the machines they power.

eFuels have a few unique characteristics:

  • They have the potential to achieve carbon neutrality because they emit as much carbon dioxide as was used to make them
  • They’re often derived from plant or microorganism processes like photosynthesis
  • They’re designed to be interchangeable with fossil fuels powering machinery and vehicles

How Are eFuels Produced?

Currently, eFuels are produced primarily with the help of plants.

  1. Plants use captured carbon dioxide from the atmosphere (or collected hydrogen from water electrolysis processes) as energy for photosynthesis.
  2. As plants photosynthesize, they create stored chemical energy to sustain their growth.
  3. The stored chemical energy is extracted, processed, and refined to create carbon-based fuels for various uses.

Types of eFuels: Power-to-Gas and Power-to-Liquid

Currently, there are two distinct types of eFuels: power-to-gas (PtG) and power-to-liquid (PtL) fuels.

While both are derived from the processes above, their classification depends upon the kind of product each procedure creates. To that end, both liquid and gaseous fuels can be produced via plant-based processes.

Advantages of Electrofuels

eFuels provide significant potential advantages for the planet, businesses, and individual consumers via closed-loop energy production, carbon neutrality, and simple transition.

Closed-Loop Energy Production

Instead of purchasing fuels, manufacturers could conceivably capture the CO2 emissions from combustion-based production processes to create a renewable, closed-loop for fuel production.

Carbon Neutrality

Since eFuels are made from emitted carbon, the emissions produced when they’re combusted are neutralized, meaning they emit the same amount of carbon captured to make them.

Simple Transition

Electric vehicles are a current solution to traditionally-fueled vehicles but require a mechanical and infrastructure investment. eFuels are, in theory, an immediate replacement for fossil fuels that work with current combustion engines.

4 Modern Use Cases of Electrofuels

eFuels could find a place in numerous sectors. Let’s explore four potential applications.

Road Transit

As mentioned above, eFuels could completely replace fossil fuels in road transit. The following vehicles may be powered entirely by eFuels one day:

  • Personal passenger vehicles
  • Commercial transport trucks
  • Two-wheeled personal vehicles, like motorcycles and mopeds

Consumers can continue to operate their personal vehicles. However,  with the help of eFuels, road transit could pose a lesser environmental threat.


Airplanes—used for commercial transit, military applications, and shipping—are the largest carbon emitters in the US transportation sector.

But, if eFuels are integrated throughout the aviation sector, the US could reduce its total carbon emissions profile by about three percent. While that may not sound like a staggering impact, any reduction in nationwide emissions will help us reach carbon neutrality.


Fossil fuels power many modern heating systems. Replacing household fossil fuels with eFuels could significantly reduce the climate impact of household heating at scale, leading to:

  • Reduced at-home emissions
  • Lower energy costs
  • Closed-loop energy production at home

Industrial Operations

Fossil fuels still dominate industrial processes throughout the US. In addition, large-scale manufacturing depends on traditional fuel methods since sustainable technologies aren’t yet available at a transitionable scale.

Since eFuels could, in theory, replace fossil fuels overnight, they could also solve widespread industrial emissions and significantly reduce manufacturing’s climate impact.
