Abstract Amid a relentless global climate crisis, the 28th Conference of Parties (COP28) spotlighted Direct Air Carbon Capture (DACC) as key intervention to mitigate escalating temperatures and CO 2 levels. The Intergovernmental Panel on Climate Change (IPCC) underscores urgency this challenge, stipulating need for robust removal strategies. It sets daunting yet crucial target: capture 85 million metric tons by 2030, 980 2050, achieve net-zero emissions (IEA, Executive Summary—Direct 2022—Analysis. https://www.iea.org/reports/direct-air-capture-2022/executive-summary ). Despite imperative, existing 19 operational DAC facilities globally face significant barriers, including prohibitive costs stringent regulations, which impede their large-scale application (Ozkan et al.). Current status pillars direct air technologies. Iscience (2022). While COP28 stopped short delineating definitive roadmap DAC, article addresses vital aspect technology: processes’ substantial energy heat requirements, are integral efficiency economic viability. This illuminates pathways future technological evolution cost optimization through an in-depth analysis these thereby charting course toward more effective scalable infrastructure. Graphical abstract Highlights With atmospheric exceeding 420 ppm, clock is ticking crisis. offers revolutionary approach directly remove excess , acting critical tool in our fight sustainable future. However, current systems challenge high consumption. Continuous fan operation intake sorbent material regeneration, consuming nearly 2000–3000 kWh per ton captured, major contributors. Optimizing processes crucial. Advancements efficiency, system design that minimizes parasitic losses, seamless integration with renewable sources slashing DAC’s demands. By reducing its carbon footprint enhancing viability, advancements can unlock full potential become game-changer combating change securing cleaner planet. Discussion Given requirements DACC processes, what innovations necessary make efficient economically viable? Considering demands most promising avenues enhance technology's scalability cost-effectiveness? How limitations be overcome scale up effectively? What role could play meeting facilities, how might impact overall process? do technologies influence location infrastructure needs, particularly relation sinks? or currently being explored optimize challenges they terms implementation scaling? achieving targets, policy regulatory frameworks designed support development deployment energy-efficient solutions?

Direct Air Capture (DAC) for Achieving Net-Zero CO2 Emissions: Advances, Applications, and Challenges

Eng—Advances in Engineering, Год журнала: 2024, Номер 5(3), С. 1298 - 1336

Опубликована: Июль 4, 2024

Carbon dioxide (CO2), as the primary greenhouse gas, has significant impacts on global climate change, leading to severe and irreversible adverse consequences for ecosystems human environments. To address issue of excessive CO2 emissions, efforts in recent years have yielded progress development clean energy sources promotion carbon capture, utilization, storage (CCUS) technologies. Conventional capture techniques are limited addressing atmospheric excess effectively, they target only high-concentration emissions require implementation at specific emission points. Direct air (DAC) technology emerged a promising solution due its flexibility deployment, avoidance land competition, ability legacy emissions. Additionally, DAC offers opportunities producing synthetic fuels, thereby reducing reliance traditional fossil fuels aiding gas This study provides comprehensive review technology, encompassing principles, technological advancements, real-world applications, challenges, future research directions. By offering insights into current state potential this aims guide scaling up ultimately contributing achieving neutrality or even negative
