Special Issue Information

Dear Colleagues,

Currently, increasing anthropogenic emissions of CO₂ are identified as the major driver of global warming. Carbon dioxide capture, utilization, and storage (CCUS) technology is broadly recognised as one of the near-term to mid-term solutions, which plays a key role with respect to climate change mitigation.

This Special Issue titled “Carbon Dioxide Capture, Utilization, and Storage (CCUS)” invites articles that address state-of-the-art technologies and new developments for CCUS, including but not limited to precombustion carbon capture, post-combustion carbon capture, oxy-fuel or chemical looping combustion, CO₂ conversion to generate synthetic fuels, biomass thermal conversion, CO₂ storage, BECCUS, and other negative emission technologies. Articles that engage with the latest research topics with respect to CCUS are particularly encouraged, such as direct air capture, electrochemical and thermochemical CO₂ catalytic reduction, biological conversion of CO₂, etc. Moreover, articles that discuss and drive the research directions of CCUS would be of particular interest.

Breathing Planet Earth: Analysis of Keeling’s Data on CO₂ and O₂ with Respiratory Quotient (RQ), Part II: Energy-Based Global RQ and CO₂ Budget

by Kalyan Annamalai

Energies 2024, 17(8), 1800; https://doi.org/10.3390/en17081800 - 09 Apr 2024

Abstract

For breathing humans, the respiratory quotient (RQ = CO₂ moles released/O₂ mols consumed) ranges from 0.7 to 1.0. In Part I, the literature on the RQ was reviewed and Keeling’s data on atmospheric CO₂ and O₂ concentrations (1991–2018) were used in the estimation of the global RQ as 0.47. A new interpretation of RQ_Glob is provided in Part II by treating the planet as a “Hypothetical Biological system (HBS)”. The CO₂ and O₂ balance equations are adopted for estimating (i) energy-based RQ_Glob(En) and (ii) the CO₂ distribution in GT/year and % of CO₂ captured by the atmosphere, land, and ocean. The key findings are as follows: (i) The RQ_Glob(En) is estimated as 0.35 and is relatively constant from 1991 to 2020. The use of RQ_Glob(En) enables the estimation of CO₂ added to the atmosphere from the knowledge of annual fossil fuel (FF) energy data; (ii) The RQ method for the CO₂ budget is validated by comparing the annual CO₂ distribution results with results from more detailed models; (iii) Explicit relations are presented for CO₂ sink in the atmosphere, land, and ocean biomasses, and storage in ocean water from the knowledge of curve fit constants of Keeling’s curves and the RQ of FF and biomasses; (iv) The rate of global average temperature rise (0.27 °C/decade) is predicted using RQ_Glob,(En) and the annual energy release rate and compared with the literature data; and (v) Earth’s mass loss in GT and O₂ in the atmosphere are predicted by extrapolating the curve fit to the year 3700. The effect of RQ_Glob and RQ_FF on the econometry and policy issues is briefly discussed. Full article

Abstract

This publication discusses the experiments and findings of project ROCCS (Establishing a Research Observatory to Unlock European Coal Seams for Carbon Dioxide Storage), which aimed to investigate the potential for carbon dioxide storage in coal seams. The project involved large-scale ex situ laboratory tests, where CO₂ was injected into an experimental coal seam using a high-pressure reactor at the Central Mining Institute in Poland. The reactor simulated underground conditions, and the experimental coal seam measured 3.05 m in length with a cross-section of 0.4 × 0.4 m. Parameters such as gas flow, temperatures, and pressures were monitored during the experiments. In the study conducted, the sorption capacity of coal from the Polish mine “Piast-Ziemowit” for CO₂, at a sorption pressure of 30 bar, was determined to be 4.8% by weight relative to the raw coal mass. The data collected from these ex situ tests can support the design of a potential commercial-scale CO₂ storage installation. Full article

A Novel Multi-Phase Strategy for Optimizing CO₂ Utilization and Storage in an Oil Reservoir

Abstract

In this paper, an innovative multi-phase strategy is developed and numerically tested to optimize CO₂ utilization and storage in an oil reservoir to support low carbon transition. In the first phase, the water-alternating-gas (WAG) injection is conducted to simultaneously store CO₂ and produce crude oil in the reservoir from the respective injection and production wells. In the second phase, the injection and production wells are both shut in for some time to allow CO₂ and water to be stratigraphically separated. In the third phase, CO₂ is injected from the upper part of the reservoir above the separated water layer to displace water downwards, while fluids continue to be produced in the water-dominated zone from the lower part of the production well. Lastly, the production well is finally shut in when the produced gas–water ratio (GWR) reaches 95%, but CO₂ injection is kept until the reservoir pressure is close to the fracture pressure of its caprocks. The numerical simulations show that implementing the proposed multi-phase strategy doubles CO₂ storage in comparison to applying the WAG injection alone. In particular, 80% of the increased CO₂ is stored in the third phase due to the optimized perforation. In addition, the CO₂ injection rate in the last phase does not appear to affect the amount of CO₂ storage, while a higher CO₂ injection rate can reduce the CO₂ injection time and accelerate the CO₂ storage process. In the proposed strategy, we assume that the geothermal energy resources from the produced fluids can be utilized to offset some energy needs for the operation. The analysis of energy gain and consumption from the simulation found that at the early stage of the CO₂-WAG phase, the energy gain mostly comes from the produced oil. At the late stage of the CO₂-WAG phase and the subsequent phases, there is very little or even no energy gain from the produced oil. However, the geothermal energy of the produced water and CO₂ substantially compensate for the energy loss due to decreasing oil production. As a result, a net energy gain can be achieved from the proposed multi-phase strategy when geothermal energy extraction is incorporated. The new multi-phase strategy and numerical simulation provide insights for practical energy transition and CO₂ storage by converting a “to be depleted” oil reservoir to a CO₂ storage site and a geothermal energy producer while enhancing oil recovery.

Abstract

Coal fly ashes (COFA) are readily available and reactive materials suitable for CO₂ sequestration due to their substantial alkali components. Therefore, the onsite collaborative technology of COFA disposal and CO₂ sequestration in coal-fired power plants appears to have potential. This work provides an overview of the state-of-the-art research studies in the literature on CO₂ sequestration via the mineralization of COFA. The various CO₂ sequestration routes of COFA are summarized, mainly including direct and indirect wet carbonation, the synthesis of porous CO₂ adsorbents derived from COFA, and the development of COFA-derived inert supports for gas-solid adsorbents. The direct and indirect wet carbonation of COFA is the most concerned research technology route, which can obtain valued Ca-based by-products while achieving CO₂ sequestration. Moreover, the Al and Si components rich in fly ash can be adapted to produce zeolite, hierarchical porous nano-silica, and nano-silicon/aluminum aerogels for producing highly efficient CO₂ adsorbents. The prospects of CO₂ sequestration technologies using COFA are also discussed. The objective of this work is to help researchers from academia and industry keep abreast of the latest progress in the study of CO₂ sequestration by COFA. Full article
