US-based startup Aircela has unveiled an innovative device that can produce gasoline directly from the air. This device operates through a three-stage process. Initially, it captures carbon dioxide from the atmosphere. Subsequently, it electrolyzes water vapor to generate hydrogen. Finally, it synthesizes hydrocarbons using these two substances as feedstock, which are then transformed into methanol and, ultimately, into gasoline for output.

At present, the technology has certain limitations. Each unit can only produce about one gallon (approximately 3.8 liters) of gasoline per day, with a maximum storage capacity of 17 gallons. The targeted price range for this device is between $15,000 and $20,000, with the possibility of price reductions following mass production. Additionally, the device supports the operation of multiple units in parallel.

Energy conversion efficiency stands as a pivotal factor that restricts its economic feasibility. The goal is to achieve a full-process energy efficiency exceeding 50%. This technology is heavily reliant on sustainable energy sources as a fundamental prerequisite for its commercial viability, making it particularly well-suited for remote desert regions. Looking ahead, it's conceivable that car owners might even have the capability to produce gasoline right in their own homes.
