Innovations in Carbon Capture and Storage/Utilization (CCS-CCU): Sustainable Engineering and Biotechnological Perspectives

Dear Colleagues,

The imperative to address climate change has propelled Carbon Capture, Utilization, and Storage (CCUS) technologies to the forefront of sustainable solutions. These encompass various strategies to capture carbon dioxide emissions, repurpose the captured CO₂, and securely store it. As the global carbon landscape evolves, ongoing advancements in CCUS processes and materials are vital. Innovative capture methodologies, utilization pathways, and secure storage techniques synergize to revolutionize emission reduction efforts. Amidst escalating climate change concerns, this Research Topic aims to explore recent strides in CCS/CCU technologies, focusing on both engineering and biotechnological advancements shaping carbon management's future.

This Research Topic aims to tackle the challenge of advancing CCUS technologies to effectively reduce carbon emissions. The goal is to examine current gaps and opportunities, emphasizing novel approaches to enhance efficiency, scalability, and sustainability, particularly in advanced engineering and biotechnological domains. These solutions are critical for technology development, deployment risk mitigation, and the promotion of comprehensive understanding of CCUS processes.

This Research Topic encompasses recent CCS/CCU technology advances, emphasizing advanced engineering and biotechnological solutions. Authors are encouraged to explore innovative capture methods, CO₂ utilization pathways, and secure geological storage techniques. Potential themes include the following:

• Advances in CO₂ capture technologies such as Absorption, Membrane Separation, Adsorption, Calcium Looping, Algae-Based Carbon Capture, Microbial Electrosynthesis, and Bioenergy with Carbon Capture and Storage (BECCS).
• Novel CO₂ utilization strategies including chemical conversion, carbonate precipitation, concrete carbonation, mineralization, algae cultivation, and biotechnological processes for converting CO₂ into valuable products like biofuels, chemicals, and materials.
• Developments in CO₂ transportation methods, infrastructure planning, safety protocols, and integration with utilization and storage systems.
• Sustainability and Environmental Impact Assessments evaluating the environmental benefits, carbon footprint, and potential drawbacks of innovative and biotechnological CCS/CCU approaches via life cycle assessments (LCA).
• Industry and Market Integration Studies examining the integration of innovative CCS/CCU technologies into the existing industrial processes, market trends, and commercialization opportunities.

We welcome original research articles, reviews, and case studies presenting scientific insights, technological innovations, and practical applications. This Special Issue fosters interdisciplinary discussions and encouraging collaborations among researchers, engineers, and CCUS experts towards a sustainable, low-carbon future.
