The aim of this work was to evaluate PSA processes for removal of CO₂ from NG at high pressure. For this, the study performed a techno-economic comparison of a PSA with an amine based solvent process and identified candidate materials for the PSA process.
The combined meeting of the IEAGHG Monitoring and Modelling Networks took place at the Edinburgh Centre for Carbon Innovation from the 6-8th July 2016. The meeting brought together leading experts from research and industry to discuss the latest work and developments, with around 60 participants from 11 countries participating.The theme for this meeting was ‘using the modelling-monitoring loop to demonstrate storage performance more effectively’. Sessions on monitoring included induced seismicity, novel monitoring techniques, monitoring costs, near-surface natural variability, monitoring CO<sub>2</sub>-EOR, wellbore integrity issues, modelling environmental conditions, updates from ongoing and closed projects, lessons from other industries, modelling reservoirs and overburden, pressure measurements and conformance in the monitoring modelling loop.
The study is a first stage assessment of a novel concept of transporting ethane from the USA in dedicated maritime carriers to Europe, which are modified from standard designs to be equipped to carry both ethane and CO<sub>2</sub>, so that CO<sub>2</sub> can be transported back (back hauled) to the USA for use in CO₂-EOR operations.
Over the past years a number of demonstration CCS projects have been developed around the world with the aim to provide valuable information, assist in the design of large CO<sub>2 </sub>capture plants and to advance the understanding of CO<sub>2 </sub>behaviour in the subsurface. The objectives of the CCS demonstration projects can be summarized as follows: <!-- wp:acf/columns {"name":"acf/columns","data":{"padding_top":"1","_padding_top":"field_columns_fields_padding_top","padding_bottom":"1","_padding_bottom":"field_columns_fields_padding_bottom","margin_top":"0","_margin_top":"field_columns_fields_margin_top","margin_bottom":"0","_margin_bottom":"field_columns_fields_margin_bottom"},"mode":"preview"} --> <!-- wp:acf/column-content {"name":"acf/column-content","mode":"preview"} --> <!-- wp:list --><ul> <!-- wp:list-item --><!-- wp:list-item --><li>Demonstrating the technical feasibility of a particular technology</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Gaining operational experience and economic information</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Gathering data to support the development of large scale projects</li><!-- /wp:list-item --><!-- /wp:list-item --></ul><!-- /wp:list --> <!-- /wp:acf/column-content --> <!-- /wp:acf/columns --> The purpose of this technical review is to provide an overview of the major on-going Demo CCS projects applied to SMR Hydrogen Plants with a focus on the CO<sub>2 </sub>capture system. In particular, the technical approach used for the design and execution of the Demo Plants and the relevant peculiarities are outlined.
The purpose of this report is to present a reference document that describes the technical basis and key assumptions to be used in evaluating the performance of the integrated oil refinery without and with CO<sub>2</sub> capture. The engineering and design basis, and various assumptions on feedstock, additives, products and by-products, and the specification of the CO<sub>2</sub> that are outlined in this report will be used as a reference for developing the refinery configurations to be developed in the study which will be published once the project is completed. Where applicable, information retrieved from IEAGHG document “Criteria for Technical and Economic Assessment of Plants with Low CO<sub>2</sub> Emissions” Version C-6, March 2014, are included.
The aim of the workshop was to review the representation of carbon capture and storage (CCS) and advanced fossil technologies in integrated assessment models (IAMs). IAMs are computer models and can range in the mathematical methods that underpin them, but largely they incorporate representations of the energy system, the economy and earth systems into one IAM. These computational models are then used at global, national and city scales to gain insights into energy and economic system dynamics under various constraints, e.g. from government policy, from socio-economics and from the environment. IAMs are widely used in energy and climate change mitigation scenario analysis to develop technology roadmaps and inform policy pathways.
This study compares the anticipated CCS build-out rates with those achieved in other sectors, where comparable technologies in those sectors have been used as analogues. In particular, it addresses whether the build-out rates for CCS, as depicted in Figure ES.1, are tenable, i.e. whether the claimed build out is possible once the programme is up and underway. It does not attempt to address the timing of when the build-out would begin or, more particularly, the veracity of the timing of the start of build-out as depicted in Figure ES.1.
The aim of this study was to characterise key countries and regions worldwide where carbon capture and storage (CCS) could play an important role in mitigation efforts, based on national circumstances and priorities. An additional objective was to identify how international frameworks, such as the UNFCCC, can support CCS and what these new architectures would mean with respect to development of nationally determined contributions (NDCs).
This report documents the subsurface processes that may enable CO₂ to potentially migrate from the storage reservoir to within the overburden sequence. The potential rates of migration for each migration pathway and the implications for leakage are discussed. Secondary trapping mechanisms within the overburden are also discussed within the report. The conclusions are focused on tying overburden characteristics to their impact on developing risk assessments. As well as specific pathway structures, five CO₂ storage projects were selected for this review and the characteristics of the overburden sequence that promote trapping and hinder migration at each site are a summarised. The projects chosen were the offshore Sleipner and Snøhvit CO₂ storage projects, the planned storage site in the Goldeneye Field, the onshore Ketzin pilot CO₂ injection project in Germany and the Field Research Station in Canada.
The main purpose of the study was to evaluate the cost of retrofitting CO₂ capture in a range of refinery types typical of those found in Europe. These included bo0th simple and high complexity refineries covering typical European refinery capacities from 100,000 to 350,000 bbl/d. The assessments performed in this report focused on retrofit costs including modifications in the refineries, interconnections, and additional CHP and utility facilities. The main focus of the study was on CO₂ capture from refinery Base Case 4, which was considered to be the most relevant reference for existing European refineries of interest for CO₂ capture retrofit. Considering the large number of cases (16) and their complexity, a hybrid methodology is used to evaluate the cost of the sections (CO₂ capture and compression, utilities, and interconnecting) of the concept. In this approach, four of the 16 capture cases were selected to represent a wide range of CO₂ capture capacity and flue gas CO₂ content. In each case, detailed assessments were undertaken. These detailed cost assessments form, based on subsequent scaling, the basis for the assessment of the other cases. The scaling equations have a larger purpose in that they can be used by refineries/policy experts to evaluate capital costs of retrofitting CO₂ capture to refineries of interest.

This technical review has been undertaken with the aim of providing a summary of the current status of research into greenhouse gas emissions in the natural gas supply chain. Although 90% or more of the CO<sub>2</sub> produced at gas fired power plants can be captured, emissions from the supply chain may reduce the near-zero-emission image of gas as an energy source.
