Jafarbeigi & Ayatollahi (2025): An innovative technique and laboratory protocol for CO₂ storage in water disposal wells and monitoring asphaltene deposition

Ehsan Jafarbeigi and Shahab Ayatollahi, IN: Nature – Scientific Reports, https://doi.org/10.1038/s41598-025-32916-9

Injecting CO₂ into water-disposal wells is a promising strategy for geological carbon storage. However, this process can destabilize asphaltenes in residual oil blobs—primarily of the emulsified type—trapped within the porous rock, leading to precipitation that threatens storage integrity and operational safety. This study introduces a novel high-pressure laboratory apparatus and protocol designed to directly quantify asphaltene precipitation during CO₂ injection into oil-in-water emulsions, which represent water-flooded formations.

Martirosian et al. (2025): Alignment of international standards for carbon dioxide removal (CDR) using Carbon Capture and Storage (CCS): Comparative analysis of the EU Carbon Removal and Carbon Farming (CRCF) Regulation against the Integrity Council for the Voluntary Carbon Market (ICVCM) and Article 6.4 of the Paris Agreement

Natasha Martirosian, Murali A Thoppil, Evangelos Mouchos, Joanna House, Julian Smart, Injy Johnstone, Luka Štrubelj and Isabela Butnar, IN: University of Bristol, https://doi.org/10.71706/92435e1c-c500-43ce-be95-1007565ebc7a

Achieving net-zero climate goals requires carbon dioxide removal (CDR). Doing this with credibility and trust requires robust standards for measuring reporting and verification of removals. In the UK context, the UK government has commissioned the British Standards Institution (BSI) to develop standards for Bioenergy with Carbon Capture and Storage (BioCCS) and Direct Air Capture with CCS (DACCS), with detailed methodological approaches under development. To inform this process, this report critically compares three international protocols: The Carbon Removal and Carbon Farming (CRCF) Regulation EU 2024/3012 (and related regulations) is assessed against the the Integrity Council for the Voluntary Carbon Market (ICVCM) Core Carbon Principles and Article 6.4 of the Paris Agreement.

Kloesel et al. (2025): Carbon Dioxide Reduction and Removal toward Net-Zero: A Needed Change of Narrative

Katrina Kloesel, Vittoria Bolongaro, Paolo Gabrielli, Viola Becattini, Marco Mazzotti, IN: Industrial & Engineering Chemistry Research, https://doi.org/10.1021/acs.iecr.5c00684

This work provides a simple physical framework to analyze the challenges related to achieving a net-zero carbon dioxide (CO₂) emission target, with a specific focus on CO₂ management solutions based on CO₂ capture and storage (CCS), biomass use with CCS, and direct air capture of CO₂ from the atmosphere with permanent storage. The framework is based on a simplified schematic of the Earth system, a simple mathematical model of such a system, and a graphical representation of it (called a scenario diagram), where the states of the Earth system can be mapped, from the net-positive world of today to any net-zero and net-negative future scenario.

Bataille et al. (2025): Defining ‘abated’ fossil fuel and industrial process emissions

Christopher Bataille, Alaa Al Khourdajie, Heleen de Coninck, Kiane de Kleijne, Lars J. Nilsson, Igor Bashmakov, Steven J. Davis, Paul S. Fennell, IN: Energy and Climate Change, https://doi.org/10.1016/j.egycc.2025.100203

There is scientific consensus that limiting warming in line with the Paris Agreement goals requires reaching net zero CO₂ emissions by mid-century and net negative emissions thereafter. Because of the entrenchment of current fossil fuel energy and feedstock demand estimated in almost all global modelled scenarios, “abated” fossil fuel and industrial process and product use (IPPU) CO₂ emissions, using carbon capture and storage (CCS) technologies to perform carbon management, are likely to be part of any transition. In addition to fossil fuel combustion, this will be primarily in cement & lime kilns, chemical production, and possibly waste incineration and iron and steel making, in processes producing maximally concentrated CO₂ waste streams. Abated fossil fuel and IPPU CO₂ emissions in the context of recent commitments, however, requires consideration of capture rates for fuel processing and end-use, permanence of storage, reduction of upstream production and end-use fugitive methane, and sufficient means to sequester residual emissions. Based on an assessment of evolving CCS technologies in existing sectors and jurisdictions, criteria are proposed for defining a benchmark for “abated” fossil fuel and IPPU emissions as where near 100 % GHG abatement is to be eventually achieved, with N₂O and fluorinated gases considered separately.

Science – Tangparitkulet al. (2025): CO₂ storage infrastructure and cost estimation for bioenergy with carbon capture and storage in Northern Thailand

Suparit Tangparitkul, Thakheru Akamine, Romal Ramadhan, Vorasate Thanasaksukthawee, Chetsada Tapanya, Thanapol Tantisattayakul and Premrudee Kanchanapiya IN: Carbon Capture Science & Technology, https://doi.org/10.1016/j.ccst.2025.100425

The current study evaluated CO₂ storage infrastructure in Northern Thailand’s onshore saline formations to support BECCS deployment and contribute to the nation’s decarbonization goals under its Nationally Determined Contribution. The geological storage potential, CO₂ plume migration, storage containment, and cost estimates of the Lampang and Nong Bua Basins were comprehensively assessed. Numerical simulations were performed to evaluate storage capacities and containment mechanisms, incorporating reservoir heterogeneity and geomechanical constraints.

Otabir et al. (2025): Geochemical Impacts of CO2 Mineralization in Carbonate and Basalt Formations: A Critical Review on Challenges and Future Outlook

Prince N. Y. M. Otabir, Aaditya Khanal, Fatick Nath IN: Energy & Fuels, 2025, https://doi.org/10.1021/acs.energyfuels.4c04424

Although sandstone reservoirs have been widely used for Carbon capture and storage (CCS) due to their favorable properties, their effectiveness is limited by slow mineral trapping. This review explores carbonate and basaltic formations as alternative CO2 storage solutions. Basalt formations contain highly reactive minerals that promote rapid CO2 mineralization. Pilot studies have demonstrated successful mineralization within 2 years. Carbonate formations also show promise for efficient CO2 trapping. However, several challenges must be addressed. These include complex interactions between CO2 and rock substrates, difficulties characterizing carbonate formations, and variable behavior in basalt formations under different conditions. This review comprehensively reviews and analyzes the current state of the art on the dissolution and mineralization processes in carbonate and basalt formations.

Berlianti et al. (2024): Evaluation of Potential Use of Multi-Level Sprayer and Electronic Controlling in Simple Wet Scrubber for CO2 Removal and Water Usage Efficiency Enhancement

 Berlianti Berlianti, Indra Agus, Rahmi Berlianti IN: Journal of Advanced Research in Applied Sciences and Engineering Technology, 51(1), https://doi.org/10.37934/araset.51.1.218228

The work evaluates whether applying a multi-level sprayer with electronic control can reduce the value of CO2. The study’s objective is to assess the potential utilisation of multi-level sprayers and electronic control in determining the efficiency of a basic wet scrubber for removing CO2 generated from burning garbage, particularly dry waste like paper, with the additional goal of minimising water usage. The system will be built in a small and simple wet scrubber with dimensions of 60 cm in height and about 40 cm in length and width. CO2 value and water usage in the wet scrubber will be measured.

Nature – Wijaya et al. (2024): Basin-scale study of CO2 storage in stacked sequence of geological formations

Nur Wijaya, David Morgan, Derek Vikara, Timothy Grant, Guoxiang Liu IN: scientific reports, 14, https://doi.org/10.1038/s41598-024-66272-x

Commercial scale decarbonization through carbon capture and storage may likely involve many CO2 storage projects located in close proximity. The close proximity could raise concerns over caprock integrity associated with reservoir pressure buildup and interference among adjacent projects. Commercial-scale injection will also require large prospective CO2 storage resource and high injectivity in the targeted storage formations. To accommodate the need for both large resource and high injectivity, project operators could consider injecting CO2 into a stacked sequence of formations. This analysis investigates the benefits of injecting CO2 into a vertically stacked sequence of saline formations, over injecting the same amount of CO2 into a single saline formation, in addressing these challenges.
