7 h. ago Turning pollution into clean fuel with stable methane production from carbon dioxide

Carbon dioxide (CO2) is one of the world's most abundant pollutants and a key driver of climate change. To mitigate its impact, researchers around the world are exploring ways to capture CO2 from the atmosphere and transform it into valuable products, such as clean fuels or plastics. While the idea holds great promise, turning it into reality—at least on a large scale—remains a scientific challenge.

Over the past decades, energy researchers have developed various promising solutions to limit the emission of greenhouse gases and source fuels or other chemicals more sustainably. These solutions include so-called carbon capture technologies and electrolyzers, devices that can capture carbon dioxide (CO2) and convert it into other valuable products, such as carbon monoxide (CO), methanol (CH OH), methane (CH ) and various other compounds.

Southwest Research Institute produced a batch of blended sustainable aviation fuel (SAF) through a refinery process that started with electrofuels or e-fuels made from carbon dioxide and green hydrogen. A multidisciplinary team produced and characterized the SAF, along with two other commercially available fuels, before collecting emissions and particulate data to support the aviation industry's emissions goals.

Hydrogen fuel provides energy without producing carbon dioxide emissions, which makes it a promising option for decarbonizing the economy. The U.S. is a major producer of hydrogen, contributing around 10% of the global annual production, but the quantity of emissions produced when hydrogen is harvested depends on the method.

The ocean is Earth's largest carbon sink, absorbing about 25% of the CO released by human activities. However, this uptake contributes to ocean acidification and risks destabilizing marine ecosystems. Utilizing this carbon resource presents a sustainable alternative to fossil fuels to produce important chemicals and materials, such as plastics.
