7th International Workshop on Offshore Geologic CO2 Storage

Overview

The 7th International Workshop on Offshore Geologic CO2 storage was held in Port Arthur, TX, on September 17-18th, hosted by the Port Arthur Chamber of Commerce and co-organized by the University of Texas and the IEAGHG. There was around 60-70 in-person attendees, with over 200 participants joining online.

Summary

This workshop was established 8 years ago to promote knowledge sharing about oshore geologic CO2 storage. The first workshop was held in 2016 in Austin, Texas, followed by workshops in Beaumont, Texas (2017), Oslo, Norway (2018), Bergen, Norway (2020), New Orleans, Louisiana (2022), and Aberdeen, UK (2023). Over the years, the workshop has grown to involve over 30 international CO2 storage projects from countries like Norway, the Netherlands, and the United States.


There is a lot of storage potential offshore and there are many benefits to oshore storage. Often close to the industrial areas where a lot of the sources are and many legal aspects such as pore space ownership is more straightforward. Port Arthur was chosen as this year’s as it is a large energy hub with rapid developments in CCS.


With over 20 oshore CCS projects, both commercial and research-focused, discussed in presentations representing 12 countries, key topics included challenges and solutions related to depleted oil and gas fields, shipping for offshore injection, public engagement strategies, risk management concerning potential leakages, challenges associated with CO₂ phase changes, well risk management exercises, CO₂ stream analysis, and regulatory frameworks.

The 7th International Workshop on Offshore Geologic CO2 Storage kicked off with a warm welcome from hosts Joe Tant, CEO of the Port Arthur Chamber of Commerce, and Dr Betty Reynard, president of the Lamar State College, Port Arthur. With 742 energy facilities, Port Arthur is the energy hub of Texas, the region is proud of its success and proud to be part of the energy sector and has a close relationship with the facilities and keen to be part of the future direction of energy transition.

Insurance Coverage for CO₂ Storage Projects

  • 16 August 2024
  • Industry Insights
  • Storage

This report is a focused review of recent developments regarding insurance coverage for carbon dioxide (CO₂) geological storage projects. It seeks to address the following: what companies are offering or planning to offer insurance to CO₂ storage projects, what is the scope and duration of the coverage offered, and does coverage extend to the transportation of CO₂ to the project site? This work and report was prepared by Franz Hiebert.

  • Storage

This Technical Review provides an overview of 22 CO₂ storage sites from around the world. These include CO₂-EOR, commercial scale storage sites and a number of pilot and demonstration storage sites in both depleted hydrocarbon reservoirs and saline reservoirs. Its primary aim is to provide a convenient source of collated information with a specific focus on technical information that are in the public domain.

The 6th International Workshop on Offshore Geologic CO₂ Storage was held in Aberdeen on 13-14 September. Organised with the University of Texas and hosted by the University of Aberdeen. The loca on was very appropriate as we were co-hosted and sponsored by Storegga who leads the Acorn project nearby in Scotland. This project had been recently announced by the UK government as a Track 2 Cluster project. This 6th workshop had 190 delegates (60 in-person and 130 virtual) from 35 countries, with a good mix of industry, researchers and regulators.

Components of CCS Infrastructure – Interim CO₂ Holding Options

  • 27 November 2023
  • Storage
  • Transport

This work, undertaken on behalf of IEAGHG by TNO and SINTEF, provides an overview of temporary / interim CO₂ storage, or ‘holding’, options (also called buffers) and investigates the role of buffer storage and its potential to create flexible and robust carbon capture and storage (CCS) chains. The report looks at current and emerging buffer technologies, conducts simulations to demonstrate the temporary storage required for given flow-rate scenarios and discusses the impact of buffer capacity on transport costs. In the report, the storage requested in the chain for normal operation is presented as " temporary storage" and storage to give buffer capacity is presented as " buffer storage". This report has focussed on buffering at the emitter site. The results of this study will benefit CO₂ storage site project developers, operators, financiers and regulators.
