Special Issue Information

Dear Colleagues,

Carbon capture, utilization, and storage (CCUS) technologies comprise a set of proposed technological solutions that seek to trap carbon dioxide, the main form of carbon carrier molecule responsible for the greenhouse effect, before its release into the atmosphere. The aims and functions of CCUS manifest as either preventive measures that lock carbon dioxide underground or in other suitable media (carbon capture and storage, CCS), or as redirecting processes that feed it to augmented industrial cycles for manufacturing products with positive financial impacts (carbon dioxide utilization, CDU). Following recent policy initiatives and in view of the larger picture unfolding at the global theater, this Special Issue aims to elucidate the main points, considerations, and dynamics that drive modern CDU initiatives, focusing on processes for converting CO2 into fuel products and other industrial chemicals of value. The issue covers all studies related to CCUS technology with an emphasis on CDU for the industrial production of fuels and chemicals (e.g., blue hydrogen, concrete, formate and formic acid, methanol, petrochemicals, urea), CDU involving biological processes (e.g., biogas synthesis via bacterial fermentation, algae production for biofuel synthesis, and biomineralization), and processes that classify as power-to-liquid (e.g., methanol) or power-to-gas (e.g., hydrogen, methane) by utilizing surplus renewable electricity.

Cement production is responsible for about eight percent of global CO2 emissions. A potential use for CO2 is the production of synthetic fuels through power-to-X (PtX) processes. For this purpose, a potential analysis is performed in which the possibilities for CO2 avoidance and CO2 capture and utilization (CCU) in the cement manufacturing process are evaluated. Based on the potential analysis, three scenarios for the development of the German cement industry until 2050 are developed and displayed in geo-referenced form, yielding potential locations for PtX plants. Results show that it is unlikely that cement can be fully replaced by alternative construction methods or new types of binders from today’s perspective. Measures to reduce CO2 emissions in cement production are limited, especially due to the restricted possibilities to replace limestone as feedstock. In an intermediate scenario, CO2 emissions in cement production decrease by 35% until 2050 compared to the average value from the 2014–2018 reference period. For CCU to be introduced at cement plants, the additional costs must be compensated, either through revenues from CO2 certificates or economic and regulatory incentives. Full article

Addressing escalating energy demands and greenhouse gas emissions in the oil and gas industry has driven extensive efforts in carbon capture and utilization (CCU), focusing on power plants and industrial facilities. However, utilizing CO2 as a raw material to produce valuable chemicals, materials, and fuels for transportation may offer a more sustainable and long-term solution than sequestration alone. This approach also presents promising alternatives to traditional chemical feedstock in industries such as fine chemicals, pharmaceuticals, and polymers. This review comprehensively outlines the current state of CO2 capture technologies, exploring the associated challenges and opportunities regarding their efficiency and economic feasibility. Specifically, it examines the potential of technologies such as chemical looping, membrane separation, and adsorption processes, which are advancing the frontiers of CO2 capture by enhancing efficiency and reducing costs. Additionally, it explores the various methods of CO2 utilization, highlighting the potential benefits and applications. These methods hold potential for producing high-value chemicals and materials, offering new pathways for industries to reduce their carbon footprint. The integration of CO2 capture and utilization is also examined, emphasizing its potential as a cost-effective and efficient approach that mitigates climate change while converting CO2 into a valuable resource. Finally, the review outlines the challenges in designing, developing, and scaling up CO2 capture and utilization processes, providing a comprehensive perspective on the technical and economic challenges that need to be addressed. It provides a roadmap for technologies, suggesting that their successful deployment could result in significant environmental benefits and encourage innovation in sustainable practices within the energy and chemical sectors.
