Carbon capture, utilization, and storage (CCUS) is an essential tool in our ability to reduce carbon emissions, curb rising atmospheric temperatures, and address climate change. While some CCUS technologies exist today, most have been limited to pilot-scale projects due to excessive cost driven in part by poor performance of materials used carbon capture technologies, including degradation, high energy penalties for regeneration, and other process challenges. Materials research is historically time-consuming and laborious, but new capabilities in artificial intelligence (AI) are enabling acceleration of the discovery process. IBM Research is employing its expertise in AI techniques including natural language processing, machine learning, and generative modeling to create a platform to enable rapid discovery of new materials with enhanced carbon capture performance.
Negative emission technologies that remove greenhouse gases from the atmosphere are an important and critical part of the response to climate change. In particular, a lot of technologies for direct capture of atmospheric CO2, called Direct Air Capture (DAC), have been proposed in recent years. Current DAC technologies are mainly focusing on sorbent-based systems. Recently, they have developed nanometer-thick membranes that exhibit extremely high CO2 permeability, and these membranes have been successfully demonstrated to separate and capture CO2 from even very low concentrations of CO2. Process simulation studies have shown that the membrane process is a potential new DAC technology candidate. Membrane separation is unique in its low cost, small footprint, and high size scalability compared to other conventional absorber-based capture technologies. Given these features, the m-DAC system has great potential for CO2 capture and can be used in a variety of locations and scenes, including urban areas where absorber-based systems are difficult to install.
Carbfix has developed a technology that rapidly and permanently transforms captured to stone underground with the objective of fighting climate change. We will not be able to meet our climate goals without bringing such technologies to the Gigaton scale. The technology accelerates a process that is already part of the carbon cycle on Earth and is therefore environmentally friendly in addition to being cost-effective and having near unlimited storage potential globally.

The U.S. Department of Energy’s Fossil Energy and Carbon Management (DOE-FECM) R&D Program is supporting the development of transformational cost-effective carbon dioxide (CO2) capture technologies throughout the power-generation and industrial sectors as well as carbon dioxide reduction (CDR) technologies. The Carbon Capture Program is leveraging this past research in materials, equipment and process development for both current and transformational CDR technologies, such as direct air capture (DAC) and bioenergy carbon removal and storage (BiCRS), while evaluating the opportunities in direct ocean capture and enhanced weathering. Accelerating the development and deployment of these climate-critical technologies will support the U.S. goal to achieve a carbon pollution-free electricity sector by 2035 and zero-carbon economy by 2050.
Negative emission technologies, such as direct air capture (DAC), are essential for mitigating climate change. They have developed a promising new approach to DAC that combines CO2 absorption with environmentally friendly amino acids or peptides, and (bi)carbonate crystallization with simple guanidines. The resulting process is very effective and energy-efficient compared to state-of-the-art DAC technologies.
