A Way to Capture Carbon Dioxide in the Air Adapted from Information by The Ohio State University Geothermal energy can be being used to capture carbon dioxide (CO2) directly from the atmosphere. Thanks to a new study, research suggests integrating direct air capturing technologies with CO2 removal systems and geothermal power could supply sufficient energy to remove harmful levels of atmospheric CO2, while ensuring safe storage beneath the ground. “Carbon removal technologies are especially helpful in mitigating climate change because we can capture types of emissions that would be hard to cap in other ways,” said Martina Leveni, lead author of the study and postdoctoral scholar in civil, environmental, and geodetic engineering at The Ohio State University. CO2 is primarily emitted through human activities such as burning fossil fuels for heat, electricity, and transportation. Leveni’s innovative method uses natural heat from deep beneath the earth’s surface to power direct air CO2 capture (DACC) systems, creating a sustainable solution for capturing and utilizing CO2. Geologic formations containing sedimentary rock and saltwater are used to store CO2 removed from the atmosphere, which can be circulated to extract geothermal heat or it can be converted into electricity. Researchers created a case study to demonstrate the potential of their system in the U.S. Gulf Coast region, highlighting its sustainability for Direct Air CO2 Capture with CO2 Utilization and Storage (DACCUS) deployment due to ample geothermal resources. “The Gulf Coast also has the right geology to safely put CO2 underground and a decent enough heat flux that its geothermal energy could be sufficient to use,” said Jeff Bielicki, coauthor of the study and an associate professor in civil, environmental, geodetic engineering, and the John Glenn College and Public Affairs at The Ohio State University. For the geothermal heat extraction system to work effectively, it must first be primed with carbon from point sources, like factories that emit CO2 over a period of about five years until the DACCUS plant begins its extraction process. According to researchers, there is potential for as many as 25 DACCUS systems to be installed along the coast by 2050, which could significantly reduce carbon levels starting from 2030. “There’s a lot of work to be done to take into account, technological readiness and the policies needed to make that research happen,” said Leveni. GEO Petrobras Teams with a Geothermal Drilling Company Adapted from Information by the Society of Petroleum Engineers GA Drilling announced it has entered into a technical cooperation program with Brazilian national oil company Petrobras. In cooperation with Cenpes (Petrobras’ research, development, and innovation center) the partnership plans to use a next-generation downhole drilling system to reduce well construction costs and risk in challenging drilling applications. GA Drilling’s system enables the replacement of conventional drill pipe with reeled continuous tubing, thus minimizing pipe handling hazards, tripping times, and well control risk. The new technology includes sophisticated drilling automation and control systems, as well as real-time wireline communication to the surface which optimizes and drives the drilling process downhole at the rock face rather than at the surface. The partnership pairs Petrobras with GA Drilling’s technology, a downhole anchoring and drive system that will form the cornerstone of an advanced autonomous reeled drilling system. The collaboration aims to enable deep and complex offshore wells to be drilled from a light well intervention vessel rather than a more costly semisubmersible or drillship.
