In 2019, Air Company gained public attention when it produced vodka (伏特加) from carbon in the air, in order to reduce the amount of the harmful greenhouse gas in the atmosphere. Today, the company has begun using the same process to make fuel (燃料) for airplanes.
Air Company’s clean aircraft fuel, which was recently tested, could some day help the airline industry achieve its goal of net zero carbon emissions (排放) by 2050. Currently, the airline industry accounts for about 3% of total global carbon emissions each year, and mainly uses traditional, fossil-based fuels.
A number of producers of clean aircraft fuel have come out in recent years, many of whom use something like plant material and cooking oil. But Air Company’s production process starts by pulling harmful carbon emissions out of the air.
The company first harvests carbon, mostly from industrial settings. It then takes water, separates the hydrogen from the oxygen, and puts the carbon together with the hydrogen and other mixtures. After that, it distills (蒸馏) that solution down. The final products are ethyl alcohol (乙醇) to make the company’s vodka and other products such as perfume, as well as paraffin, which forms the basis of its aircraft fuel.
By the time a plane has flown using Air Company’s fuel, it will have given off the same amount of carbon dioxide (CO2) back into the atmosphere as was acquired to make the fuel.
“Already, some of the world’s biggest airlines are supporting Air Company’s dream. They have agreed to buy millions of gallons of its fuel in the coming years.” The company manager says, “However, to get to those large industrial markets like aircraft fuel, traditionally known as the hottest industry to get green, is a long way to go. It’s going to take time, money and effort.”
