Special Issue Information

Dear Colleagues,

Despite the great progress of renewable energy sources, more than 80% of global primary energy use is currently fossil-based. Global energy-related CO2 emissions increased by nearly 1% in 2022, reaching an all‐time high of approximately 37 billion tonnes (Gt). It is necessary to achieve net zero CO2 emissions from the energy sector by 2050 in order to stabilize global average temperatures below 1.5 ºC and ensure they are above pre-industrial levels by 2100. In this context, in addition to improving energy efficiency, fuel switching to low-carbon sources and boosting renewable energy, carbon capture and storage or utilization is a critical area where accelerated action in the coming decades is crucial to accomplish the ambitious mitigation goals. Carbon capture is one of the fastest growing topics in sustainable chemistry and separations science, owing to the impacts that anthropogenic CO2 are having on the climate. Enormous efforts within the scientific community have widely focused on CO2 capture from large stationary sources such as electricity-generating power plants in order to minimize emissions. The capturing of CO2 from other industrial sources (e.g., cement, steel, refineries, etc.) and also from ambient air has attracted rapidly increasing attention. The use of the captured CO2 as feedstock to produce value-added products beyond a compressed pure gas for geological storage has also been an attractive topic for research. Many catalytic applications such as artificial photosynthesis, photocatalysis, synthesis of chemistry building blocks, fuels and pharmaceutical compounds have been proposed.

This Special Issue will compile selected publications elaborated by internationally renowned researchers on this multidisciplinary research field, covering novel advances in process optimization, modelling, reactor design and high-performance materials for the capture of CO2.

To achieve net-zero emissions by the year 2050, carbon capture, utilization, and storage technologies must be implemented to decarbonize sectors with hard-to-abate emissions. Pressurized chemical looping (PCL) with a novel reactor design called a plug flow with internal recirculation (PFIR) fluidized bed is proposed as an attractive carbon capture technology to decarbonize small- and medium-scale emitters. The objective of this work is to examine the solid circulation rate between redox reactors in a cold flow chemical looping facility using an energy balance approach. The effects of static bed height, weir opening height, purge configuration, and gas flow rate on solid circulation rate were investigated. It was determined that parameters that greatly affected the total gas momentum, such as the fluidization ratio or number of purge rows, tended to also have a large effect on solid circulation rate. Parameters that had a small effect on total gas momentum, such as bed height, did not have a measurable effect on solid circulation rate. It was noted that parameters that posed a restriction to solids flow, such as a vertical purge jet or the weir itself, decreased the solid circulation rate compared to similar tests without restrictions.

Carbon capture and storage (CCS) is a critical technology for mitigating greenhouse gas emissions and combating climate change. CCS involves capturing CO2 emissions from industrial processes and power plants and injecting them deep underground for long-term storage. The success of CCS projects is influenced by various factors, including the regional pressure dissipation effects in subsurface geological formations. The safe and efficient operation of CCS projects depends on maintaining the pressure in the storage formation. Regional pressure dissipation, often resulting from the permeability and geomechanical properties of the storage site, can have significant effects on project integrity. This paper provides a state-of-art of the impact of regional pressure dissipation on CCS projects, highlights its effects, and discusses ongoing investigations in this area based on different case studies. The results corroborate the idea that the Sleipner project has considerable lateral hydraulic connectivity, which is evidenced by pressure increase ranging from <0.1 MPa in case of an uncompartmentalized reservoir to >1 MPa in case of substantial flow barriers. After five years of injection, pore pressures in the water leg of a gas reservoir have increased from 18 MPa to 30 MPa at Salah project, resulting in a 2 cm surface uplift. Furthermore, artificial CO2 injection was simulated numerically for 30 years timespan in the depleted oil reservoir of Jurong, located near the Huangqiao CO2-oil reservoir. The maximum amount of CO2 injected into a single well could reach 5.43 × 106 tons, potentially increasing the formation pressure by up to 9.5 MPa. In conclusion, regional pressure dissipation is a critical factor in the implementation of CCS projects. Its impact can affect project safety, efficiency, and environmental sustainability. Ongoing research and investigations are essential to improve our understanding of this phenomenon and develop strategies to mitigate its effects, ultimately advancing the success of CCS as a climate change mitigation solution.
