– Oregon State University has conducted a study that explores the potential of vanadium for carbon scrubbing in direct air capture (DAC) technology.
– Vanadium peroxide molecules have shown promise in their reactivity for binding carbon dioxide (CO2), and their unique properties allow for the relatively low release temperature of captured CO2, which could lead to energy and cost savings in carbon capture processes.
Oregon State University researchers have made progress in advancing direct air capture (DAC) technology with a new study focused on the potential of vanadium for carbon scrubbing. DAC involves capturing carbon directly from the air, and carbon filtering facilities are still in the early stages of development. The study found that vanadium peroxide molecules exhibit optimal reactivity, making them promising candidates for binding carbon dioxide (CO2). This binding is a crucial step in enhancing technologies for atmospheric carbon removal.
May Nyman, leading one of nine DAC projects funded by the U.S. Department of Energy, spearheaded the research. Her team’s focus on vanadium found that it effectively binds CO2 with the aid of alkali cations for charge balance. Attempts with other metals or substituting alkali compounds yielded less favorable results. Vanadium’s unique properties also allow for the relatively low release temperature of captured CO2, which could result in energy and cost savings in carbon capture processes. The research, published in Chemical Science, involved collaboration with scientists from Pacific Northwest National Laboratory and the University of Oregon.
The study highlights the importance of exploring new frontiers in carbon capture research and the potential for DAC technology to play a role in mitigating climate change. DAC technology is still in its early stages of development, but advancements like this study provide hope for the future of carbon removal and emission reduction efforts.
