Discover the latest advances carbon capture and storage research
An evaluation of various electrolytic hydrogen production pathways focusing on their technical, economic, and environmental aspects and comparing these with hydrogen production routes that involve fossil fuel with carbon capture and storage (CCS) abatement.
The 7th International Workshop on Offshore Geologic CO2 storage was held in Port Arthur, TX, on September 17-18th 2025.
CO2 leakage from geological storage is considered unlikely. However, it is important to understand environmental and health risks to ensure appropriate mitigation and monitoring is established.
This study presents a systematic review of waste-to-hydrogen (WtH) technologies and conducts analysis of the technological, economical, and environmental aspects of the most promising waste-to-low carbon hydrogen technologies for near-term commercial deployment.
This report evaluates progress, barriers, and knowledge gaps, and provides stakeholders, regulators, and investors with a comprehensive summary of current knowledge and understanding of subsurface carbon mineralisation in mafic-ultramafic reservoirs.
The aim of this study is to evaluate the value of direct air capture and storage (DACCS) in the energy transition (down to the regional level), accounting for key factors, including carbon removal eiciency, timeliness, durability, land footprint and techno-economic performance.
The main objective of this study is to raise awareness of the relevance, state of the art, challenges and opportunities of flow metering for carbon capture, utilisation and storage (CCUS). Flow metering of CO2 streams will be critical in supporting trade, protecting consumers, ensuring confidence, facilitating taxation, and meeting CO2 reduction goals and treaty obligations.
This report provides a key pillar to interested parties including policy makers, regulators, and the technical carbon capture, utilisation and storage (CCUS) / carbon dioxide removal (CDR) community on potential successful market strategies, including their pros and cons and their suitability for dierent economic and political realities, which may lead to the fast development of an efficient, safe, and accepted CCUS/CDR market sector.
IEAGHG’s 8th CCS Cost Network Workshop, hosted by Bechtel at their Energy Headquarters in Houston, the so-called Energy Capital of the World, took place on March 5–6, 2025. This invitation-only, in-person gathering convened around 50 leading experts from industry and academia, fostering a highly interactive forum for in-depth discussions on advancing real-world cost estimation across the CCS value chain. The workshop was opened with welcoming remarks from Bechtel’s Bill Elliot, Operations Manager, ET, and George Whittaker, CCUS Operations Manager, which set the scene for a workshop focused on sharing expertise, challenging assumptions, and identifying practical pathways to lower CCS costs.
The objective of the study was to review publicly available information on CO2 transport and storage (T&S) costs, to provide insights into how typical cost estimates are built up and to inform on areas of risk. Current information on T&S costs and the need for new or improved data would be explored.
The IEAGHG AI in CCUS Workshop, held virtually on 29–30 April 2025, was convened to foster a deeper understanding of the role artificial intelligence (AI) can play in advancing carbon capture, utilisation and storage (CCUS).
