Chemical engineer Jingxiu Xie is on a mission to transform the aviation industry by developing a sustainable solution to power air travel. By converting carbon dioxide (CO2) into kerosene, Xie aims to reduce the environmental impact of aviation, which contributes to approximately 2 percent of global CO2 emissions. The traditional production of kerosene from crude oil involves complex refining processes, but Xie's innovative approach simplifies the conversion process, making it more energy-efficient and environmentally friendly. Her research has already attracted funding and recognition, with the goal of achieving a one-step conversion from CO2 to kerosene. While this advancement holds promise for carbon-neutral aviation fuels, challenges like the high cost of green hydrogen and limited availability of sustainable energy sources pose obstacles to widespread adoption. Xie emphasizes the need for carbon-negative solutions to address climate change effectively and highlights the importance of reducing energy consumption in the aviation sector. Despite the current hurdles, Xie's work signifies a significant step towards a cleaner and more sustainable future for air travel.
