The Martian environment is made up almost completely of co2. Astronauts might conserve half the fuel they require for a return trip house by making what they require on the red planet once they get here, Wu said.
” Its like a gasoline station on Mars. You might quickly pump co2 through this reactor and produce methane for a rocket,” Wu said.
UCs research study was published in the journal Nature Communications with collaborators from Rice University, Shanghai University, and East China University of Science and Technology.
Wu started his career in chemical engineering by studying fuel cells for electric automobiles however began taking a look at co2 conversion in his chemical engineering lab about 10 years earlier.

” I realized that greenhouse gases were going to be a big issue in society,” Wu stated. “A lot of nations recognized that co2 is a big problem for the sustainable advancement of our society. Thats why I think we need to attain carbon neutrality.”
The Biden Administration has set a goal of achieving a 50% decrease in greenhouse gas pollutants by 2030 and an economy that counts on renewable resource by 2050.
” That implies well have to recycle carbon dioxide,” Wu stated.
Wu and his trainees, consisting of lead author and UC doctoral candidate Tianyu Zhang, are try out various catalysts such as graphene quantum dots– layers of carbon simply nanometers huge– that can increase the yield of methane.
” Right now we have excess green energy that we simply get rid of. We can store this excess renewable resource in chemicals.”

Wu said the procedure holds promise to help reduce climate modification. However it also has a big commercial advantage in producing fuel as a by-product.
” The process is 100 times more productive than it was simply 10 years earlier. So you can picture that progress will come faster and faster,” Wu stated. “In the next 10 years, well have a great deal of startup companies to commercialize this strategy.”
Wus trainees are using various catalysts to produce not only methane however ethylene. Called the worlds essential chemical, ethylene is utilized in the manufacture of plastics, rubber, artificial clothes, and other items.
” Green energy will be really important. In the future, it will represent a substantial market. I desired to work on it,” Zhang said.

Synthesizing fuel from co2 ends up being a lot more commercially viable when coupled with renewable energy such as solar or wind power, Wu said.
” Right now we have excess green energy that we just toss away. We can save this excess renewable resource in chemicals,” he said.
The process is scalable for usage in power plants that can produce lots of co2. And its effective given that the conversion can occur right where excess carbon dioxide is produced.

Wu stated advances in fuel production from carbon dioxide make him more positive that humans will set foot on Mars in his lifetime.
” Right now if you want to come back from Mars, you would require to bring two times as much fuel, which is very heavy,” he stated. We can produce methanol from carbon dioxide and use them to produce other downstream products.

A gas station on Mars? Chemical engineers imagine the possibilities.
Engineers at the University of Cincinnati are developing new methods to transform greenhouse gases to fuel to address environment change and get astronauts house from Mars.
UC College of Engineering and Applied Science assistant teacher Jingjie Wu and his students used a carbon catalyst in a reactor to convert co2 into methane. Called the “Sabatier reaction” from the late French chemist Paul Sabatier, its a process the International Space Station uses to scrub the carbon dioxide from air the astronauts breathe and produce rocket fuel to keep the station in high orbit.
