Researchers have devised a novel approach to capturing carbon dioxide from the atmosphere, leveraging clean and cost-effective geothermal energy. Published in Environmental Research Letters, their study demonstrates the potential for large-scale carbon dioxide removal systems powered by a combination of direct air carbon dioxide capture technologies (DACC) and geothermal energy. Carbon dioxide emissions, primarily from fossil fuel combustion, contribute significantly to greenhouse gas accumulation and climate change. To address this challenge, efforts have focused on developing methods to extract carbon dioxide directly from the air or at the source of emissions.
Martina Leveni, lead author of the study and a postdoctoral scholar at The Ohio State University, spearheaded the investigation into integrating direct air carbon dioxide capture with geothermal energy to enhance efficiency. Known as Direct Air CO2 Capture with CO2 Utilization and Storage (DACCUS), this method harnesses geothermal energy stored in deep saline aquifers to power carbon capture systems. The captured carbon dioxide is stored underground, while a portion is recirculated to extract geothermal heat, providing renewable energy for the system's operation.
The researchers conducted a case study focused on the U.S. Gulf Coast region to illustrate the viability of their proposed system. With abundant geothermal resources and favorable geological characteristics for carbon storage, the Gulf Coast presents an ideal setting for deploying DACCUS. While the system requires initial priming, it holds promise for significantly reducing carbon dioxide emissions by 2030 and could potentially scale up to multiple installations across the region by 2050. This innovative approach underscores the importance of integrating new technologies to combat climate change effectively and highlights the potential for addressing emissions while advancing renewable energy solutions.
