CARBON CAPTURE AND UTILIZATION (CCU): A REVIEW OF EMERGING APPLICATIONS AND CHALLENGES

Abstract

As the global community grapples with the urgent need to mitigate the impacts of climate change, Carbon Capture and Utilization (CCU) has emerged as a promising and multifaceted strategy to address carbon emissions. This review paper provides a comprehensive examination of the current state of CCU technologies, focusing on both the emerging applications and the challenges inherent in their implementation. The first section offers an overview of diverse carbon capture methods, ranging from pre-combustion to direct air capture, highlighting key advancements in technologies such as chemical absorption, membrane separation, and adsorption. Subsequently, the paper delves into the various pathways of carbon utilization, exploring applications in the production of fuels, carbon-based materials, and chemical synthesis. Notable breakthroughs in power-to-gas technologies, utilization in construction materials, and industrial applications are discussed in detail. The core of the review is dedicated to unveiling the emerging applications of CCU, with a specific emphasis on its role in agriculture and soil enhancement, integration with renewable energy systems, and collaboration with other industries. The potential economic and environmental benefits of these applications are explored to underscore the transformative impact of CCU on sustainable development. However, the journey towards widespread CCU adoption is not without challenges. This paper identifies and analyzes technical hurdles related to efficiency, scalability, and cost-effectiveness. Additionally, it examines the regulatory, policy, and societal challenges that may hinder the seamless integration of CCU technologies. Case studies of successful CCU projects provide practical insights, emphasizing lessons learned and best practices. The paper concludes by outlining future prospects and opportunities in the field of CCU, emphasizing the need for continued research, development, and international collaboration. It calls for a concerted effort to overcome challenges and harness the full potential of CCU in contributing to global carbon reduction goals. This comprehensive review aims to serve as a valuable resource for researchers, policymakers, and industry professionals involved in climate change mitigation, providing a nuanced understanding of the current landscape, opportunities, and challenges associated with Carbon Capture and Utilization.
