The IEAGHG PCCC series accelerates global progress in carbon capture, utilisation and storage (CCUS), direct air capture (DAC) and bio-energy with carbon capture and storage (BECCS) by providing a trusted forum for sharing cutting-edge R&D, real-world operational insights and lessons from pilot-to-commercial-scale projects. By bringing together researchers, technology developers, industrial operators and policymakers, it helps align innovation with deployment needs, reduces technical and financial risk, and promotes the development of standards and best practices. The conference strengthens collaboration across sectors, informs policy and investment decisions with credible data and supports the scale-up of advanced capture technologies. Ultimately, this helps to enable faster, more cost-effective, and reliable deployment of carbon-removal and emissions-reduction solutions worldwide. Building on this strong track record, the PCCC-8 technical programme comprised 115 oral presentations delivered across three parallel streams comprising a total of 24 technical sessions, marking the first time the series has run three streams and representing an increase of around 40% in oral presentations compared with PCCC-7, underscoring the breadth and depth of the conference. A further 26 posters complemented the oral sessions providing additional opportunities for technical discussion. In total, PCCC-8 attracted 240 delegates from 24 countries, making it the largest PCCC to date. The presentations were selected by the PCCC-8 Technical Committee from a pool of 166 abstracts across the spectrum of post combustion capture technologies. In total, nine keynote speakers anchored the programme, providing strategic and technical perspectives that complemented the content of the technical sessions. The support of the conference sponsors, including TotalEnergies, The Shell and Technip Energies Carbon Capture Alliance, MHI, Honeywell, Axens and ION Clean Energy, was instrumental in making PCCC-8 a success. Their contributions helped to ensure that the conference could offer affordable registration fees for delegates, while maintaining a robust technical programme and an excellent overall experience. Special thanks are also due to all those involved in the organisation of PCCC-8, whose efforts enabled a productive and well-run event.
The 2nd meeting of the Network of National CCUS Centres of Excellence (NNCCE) convened national and regional CCUS centres and partner organisations from across the Global South to share updates since the first meeting in August of 2025 and to advance a practical objective of sharing information resources that can support capacity building and accelerate progress across the network. The meeting was held online on 5 February 2026 and followed a structured format of concise contributions from participating organisations, followed by discussion on shared needs, opportunities, and follow-up actions.
Data Analytics projects often suffer from low data availability, inconsistent data formats and data models. In mobility data projects this especially means there are inconsistent attributes for specifying time and space dimensions. Also, non-data
This chapter deepens the issue of “cost-benefit analysis of critical reviews” on the basis of practical experiences. It differentiates between direct and indirect advantages and also gives magnitudes of the financial costs of a review with three external experts in relation to the total cost of a life cycle assessment. Interestingly, regardless of the objective and scope of individual studies, there are recurring issues that can be conflicting in the review process. Against this background, the chapter provides practical advice on how to ensure a favourable relationship between expenditure and benefits of the review.
Inorganic sulfur (S) species including pyrite (FeS2) and sulfates may co-exist with organic matter (OM) in source rocks. Their inter-related effects on hydrocarbon generation and decomposition, and the S-34 isotope fractionation during thermal maturation remain unclear. In this study, four groups of hydrothermal experiments (kerogen with pyrite, kerogen with pyrite and gypsum, kerogen with pyrite removal, and kerogen with pyrite removal and gypsum) were conducted at 330-450 C and 50 MPa using a gold-tube system. These experiments showed that pyrite and gypsum had limited effect on the determined vitrinite reflectance (%Ro) and H/C of kerogens under hydrothermal conditions. However, the presence of gypsum led to the occurrence of TSR accelerating the decompositions of oil and hydrocarbon gases. TSR also resulted in the apparent increase of gas dryness and sourness, and the enrichment in C-13 and H-2 of methane. Experimental data confirmed that an equilibrium isotope effect (EIE) was responsible for the small S-34 fractionation between H2S and its precursor OM-S during thermal cracking of OM-S. The higher yields and more negative S-34 isotopic ratios (delta S-34) of H2S in the pyrolysis of kerogen with FeS2 revealed that the decomposition of S-34-depleted FeS2 contributed to H2S generation at elevated temperatures. Additionally, delta S-34 of pyrolysis products (i.e., oil, H2S and residual kerogens) become much more enriched with TSR. Mass balance calculations suggested that the evolution of delta S-34 of H2S from TSR in closed systems proceeded in two stages: the kinetic isotope effect (KIE) dominates the S-34 fractionation in the early stage of TSR; and S-34 exchange between sulfate and H2S is more influential in the latter/higher T stage of TSR. These conclusions may provide additional insights for understanding of S-34 isotope fractionation both in hydrothermal settings and in organic-rich shale with multiple S sources.
