Scientists are developing a pioneering method that could help remove pollution from the air, and here's how it works

Researchers have Discover A clean and relatively inexpensive way to capture global warming carbon from the atmosphere.

A team from Ohio State University has developed a method to Collecting Direct Carbon Capture (DACC) technologies use geothermal energy, and she says the process could help create large-scale carbon dioxide capture and storage systems. The researchers summarized their findings in Environmental Research Letters.

Although a potentially planet-saving technology, DACC could be just that belovedAs explained in the university’s report published on the Tech Xplore website. It also requires energy To operate – If the system uses traditional fossil fuel energy, this adds more geoheating gas to the atmosphere.

the new styleDirect Air Carbon Dioxide Capture with Carbon Dioxide Utilization and Storage (DACCUS) proposes to use heat stored underground within deep saline aquifers to produce renewable energy for DACC systems, according to the Tech Xplore publication.

The system will do it through isolation The carbon that is captured from the air into these geological formations – some of it could be carbon dioxide Circulate it To extract geothermal heat, which can be used directly or converted into electricity, according to the report.

DACC, along with other technologies like carbon capture and storage (CCS), is a way scientists are working to reduce the amount of this planet-warming gas in the atmosphere.

For example, a startup in Iceland is injecting carbon dioxide from a nearby power station into basalt rock after mixing it with groundwater, speeding up a process that normally takes thousands of years in just two years.

Likewise, nature-based solutions can help with this task. Some scientists are turning to carbon farming to manage agricultural land with the aim of improving the amount of gas stored in the soil. Others are looking to seaweeds, which provide approximately $88.3 billion in carbon storage services each year.

“Carbon removal technologies are particularly useful in mitigating climate change because we can capture types of emissions that are difficult to reduce in other ways,” said Martina Levini, lead author of the study and a postdoctoral researcher at Ohio State. Per Xplore Technology. “So we thought, can we combine technologies that could be useful to each other to achieve this goal more efficiently?”

Authors too Designed A case study to illustrate how their technology works in the US Gulf Coast region, which they say has the right geology to make it work safely.

The team says their system could be up and running 2025 And this method can begin with carbon removal 2030This is according to a report by Tech Xplore. They also estimate that as many as 25 DACCUS systems will be operating in just one of the Gulf Coast's 27 geological formations by 2050.
