Associate Professor Daniel Suess from MIT is conducting research on ancient enzymes to find sustainable alternatives for fuel production and carbon capture. By delving into the chemical principles of early cellular processes, particularly focusing on metalloproteins like iron-iron hydrogenase, Suess aims to understand electron transfer and hydrogen generation in cells. His work also seeks to offer eco-friendly substitutes for carbon-burning methods and tackle environmental issues. Suess's research on these ancient biochemical pathways not only enhances the understanding of enzyme functions but also has the potential to revolutionize carbon capture and nitrogen-to-ammonia conversion processes. Through this exploration of nature's biochemistry, Suess envisions discovering novel solutions to mitigate greenhouse gas emissions and utilize Earth's chemistry for contemporary necessities.
