Compact machine turns air into ready-to-use gasoline

Aircela's technology combines direct air capture with on-site fuel synthesis, providing fossil-free gasoline that is fully compatible with existing engines and infrastructure.

The process begins by drawing in ambient air and using a water-based solution containing potassium hydroxide to efficiently capture carbon dioxide. As air flows through a specially designed chamber, the liquid sorbent absorbs carbon dioxide from the atmosphere, which is then regenerated for repeated use. Next, the system uses renewable electricity to split water into hydrogen and oxygen through electrolysis. The hydrogen is retained for the fuel synthesis process, while the oxygen is safely released into the environment.

The captured carbon dioxide and generated hydrogen are then combined to create methanol, which is subsequently converted into gasoline using established chemical processes. The resulting gasoline contains no sulfur, ethanol or heavy metals, making it fully compatible with existing engines and infrastructure. Each Aircela unit can produce approximately one gallon of gasoline per day from around 22 pounds of captured carbon dioxide with a storage capacity of up to 17 gallons. This innovative machine enables users to generate fossil-free gasoline on site using only air, water and renewable electricity.

Unlike traditional synthetic fuel projects that rely on large, centralized plants, Aircela's approach is modular and distributed. Each unit can produce gasoline on site, making it suitable for off-grid locations, ports, islands or emergency situations. This design allows users to access cleaner fuel without the need to alter their vehicles or fueling routines.

The process developed by Aircela is intended to be carbon neutral, as the carbon dioxide released when the gasoline is burned is balanced by the amount captured during production. The gasoline works with current engines and fueling systems, so there is no need for costly upgrades. Distributed production reduces reliance on centralized refineries and long supply chains. In addition, the fuel's purity, free from sulfur and additives, helps lower harmful emissions beyond just carbon dioxide.

Aircela plans to begin initial deployments of its machines in the fall of 2025, with a focus on off-grid, commercial and industrial users. The company's goal is to increase production, reduce costs and make the technology widely available. While the current output is modest, Aircela aims to provide a practical, climate-aligned alternative to fossil fuels that does not require people to change their vehicles or daily habits.

Aircela's gasoline-from-air machine shows that sometimes the best solutions are the ones that fit right into our daily routines. Instead of requiring new cars or major changes, this technology lets people keep using what they already have, just with cleaner fuel. Watching carbon pulled from the air and turned into gasoline on the spot feels like a practical step toward a more sustainable future. 

As Aircela gets ready to roll out these machines, it will be interesting to see how this approach might help ease the transition to cleaner energy for everyone.
