Publication Overview

In April 2013, the first commercial-scale, steam methane reformer hydrogen production facility incorporating vacuum-swing adsorption carbon capture gas separation technology began full-scale operation at Air Products’ facilities located on the site of the Valero Port Arthur Refinery in Texas, USA. This report summarizes the experience of Air Products and its partners that will provide valuable insights to other petroleum refining and petrochemical industrial facilities that wish to reduce their lifecycle greenhouse gas emissions through CCUS.

Publication Summary

This project was a remarkable achievement. To date, carbon capture industrial facilities that have been constructed elsewhere have primarily utilized amine absorption carbon capture technology. This facility stands alone as a leading example of a pioneering alternative technology that was developed at record speed to enable carbon capture from steam methane reformers. Air Products and Chemicals Inc. (Air Products) responded to a request for Phase 1 proposals under the Industrial Carbon Capture and Storage (ICCS) Program of the US Department of Energy (DOE) in mid-2009. Initially, it conducted basic engineering for a BASF aMEA amine-based absorption technology, that had been commercially proven, to capture CO2 from both of its steam methane reformer (SMR) hydrogen production facilities located at the Valero Port Arthur Refinery in Texas. The two facilities (Port Arthur 1 and Port Arthur 2) were originally put into service in 2000 and 2006, respectively, and were designed to produce hydrogen, steam and power with high energy efficiency to provide “over the fence” utilities to the Valero Refinery, as well as hydrogen to supply other customers along Air Products’ Gulf Coast Connection Pipeline. i However, towards the end of Phase 1, Air Products determined that the ideal solution would be to rapidly develop and upscale vacuum swing adsorption (VSA) technology for capturing CO2 from the SMRs’ water gas shift reactor to avoid significant energy penalties and improve economics. At that time, VSA gas separation technology had not been used on a large scale for CO2 separation and purification. This proposal was approved by DOE and Air Products’ Port Arthur SMR Project proceeded to Phase 2 in June 2010.

The Role of Indices in Assessing the Maturity of CCUS Technologies and their Readiness for Deployment

  • 1 February 2024
  • Industry Insights

This study was undertaken on behalf of IEAGHG by Foresight Transitions Ltd. While a technology may be technically mature, it has become increasingly clear that the technology may not necessarily be considered commercially ‘bankable’ by investors. In this study, the potential for an index or indices to provide that confidence was explored. The findings from the study will be of interest to the broader energy community but, in particular, should benefit technology developers, CCUS end users, investors and policymakers.

Methologies and Technologies for Mitigation

  • 1 December 2023
  • Industry Insights

The driver behind this study is to develop a report built on the on the previous IEAGHG report on methods of leakage mitigation (2007/11). The proposed study should focus on current mitigation and remediation methods that may be applied or considered in site specific conditions in the event of unpredicted CO2 migration. Each geological storage site will have an adaptive site specific monitoring plan, based on a risk assessment. Detection of a significant irregularity may involve supplementing the monitoring program, in order to detect a possible leak and if necessary engaging mitigation measures.

Review of Constructability and Operational Challenges faced by CCUS projects

  • 9 September 2020
  • Industry Insights

IEAGHG has commissioned several technical studies linked to large CCS projects1. Although constructability and operational challenges have been identified in previous IEAGHG reports, some aspects were unique due to the locations where the large CCS projects were implemented. These included the status of the initial facilities and other techno-economic and financial aspects of the specific CCUS projects. IEAGHG identified the need to provide a guide on constructability and operation for new CCS users. The objective of this study is to collect information from CCS projects to support the decisions during the transition from the planning to the execution phase. This study analysed a complete list of large CCUS projects from which relevant experience could be extracted. The projects were divided into three categories: operating projects; under construction or at advanced development; and cancelled projects. Based on the analysed projects, this study has delivered an assessment of potential key areas for success, and a decision tool guide for future projects

Enabling CCS Clusters

  • 1 February 2018
  • Industry Insights

It is widely considered that deployment of carbon capture and storage (CCS) for clusters of energy intensive industries (EIIs) will become vital for meeting long-term greenhouse gas (GHG) reduction targets, and is a cost effective way for doing so, according to organisations such as the International Energy Agency (IEA) and Intergovernmental Panel on Climate Change (IPCC). In addition, it will be important to develop the related finance mechanism quickly to prevent carbon leakage, i.e. businesses transferring operations to places with less stringent GHG emission standards. Recent evidence highlights there might be different needs and challenges in deployment of industrial clusters, compared to those involving power generation. IEAGHG’s Technical Report 2015/03 “Carbon capture and storage cluster projects: review and future opportunities” reviews 12 CCS cluster projects and finds that the most successful clusters are currently based on CO2-EOR in North America. This is to be expected as EOR provides a commercial benefit to investors in such activities.Further requirements for ICCS clusters include: generating confidence for per-investment in CCS infrastructure, new methods to attract international investment and systematic development of CCS cluster business plans. However, more information is necessary regarding the transferability of conclusions for CCS clusters based on power generation incentives, such as a UK Contract for Difference (CfD), to those involving multiple industry sectors, and especially EIIs.This study examines the economic and commercial arrangements needed to enable the global deployment of industrial CCS clusters. Over a period of eight months, with significant input from stakeholders from industry, government and the investment community, the project has identified the key enablers to unlock private investment in ICCS and developed four business models, which are expected to work in various regions around the world including North America, Europe, Australia and China.

ReCAP Project Understanding Cost of Retrofitting

  • 1 August 2017
  • Costs of CCUS
  • Industry Insights

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.

IEA CCS Build Out Unit

  • 1 June 2017
  • Industry Insights

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.

  • Capture
  • Costs of CCUS

This study primarily presents a comparative analysis of steelmaking pathways to cost-effectively decarbonise a steel mill, taking a life-cycle perspective on associated environmental impacts. The roll-out of clean steel technologies is envisioned to have a significant implication for support infrastructure. Therefore, a secondary objective of the study is to gain insights into the primary energy and infrastructure implications associated with large-scale deployment of different steel decarbonisation pathways. Clean steel production will likely be more expensive than steel produced today; this poses additional economic strains on steel producers and consumers. Consequently, a third objective is to estimate the price premium that clean steel could command in existing and future markets. Further, this study formulates recommendations for key stakeholders to support the sector and outlines recommendations for further work.

  • Policy & Regulation
  • Utilisation

Over 4 billion tonnes of cement are produced each year, equating to approximately 8% of global anthropogenic CO2 emissions, and this industry will continue to grow with the expansion of the built environment at a time that emissions need to be reduced. The utilisation or reduction of CO2 within cement, concrete and building materials could be a valuable way to contribute to emissions reductions in the sector , but there are several barriers, including the current state of standards, regulations and policies. This study will provide useful information for the technical and research community, the CCUS industry, the construction industry, and policymakers, providing an unbiased and non-prescriptive evaluation of international standards and testing relevant to novel carbonaceous building materials to address some of those barriers. The market potential for CO2 utilisation processes in the construction industry is also investigated, and the methods for certifying and measuring embodied carbon content of carbonated building materials is evaluated and the challenges therein.

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.

Classification of Total Storage Resources and Storage Coefficients

  • 1 November 2023
  • Storage

The CO2 Storage Resources Management System (SRMS) is a classification scheme to quantify, classify and categorise CO2 storage resources. It comprises ‘total storage resources’, which are understood as maximum (theoretical) storage quantities that could ever be accommodated in the subsurface. Comprising maximum mobile CO2 in structural/stratigraphic traps, maximum residually trapped CO2 in other parts of the formation, and maximum dissolution potential in remaining formation water. ‘Storable quantities’ are understood as accessible from one or several current or future projects. It is the sum of capacity, contingent and prospective resources. The concept of ‘storage coefficient’ ‘E’ is the ratio of the subsurface volume of CO2 storable quantities to either the total storage resources or the pore volume. The calculation is arguably complicated as E is impacted by lithological heterogeneity, trapping structures, boundary conditions, injection rates, well spacing, fluid properties etc. Due to its complexity, there is much controversy on how to estimate E, with some arguing it should not be used at all and that reservoir simulation is a better path. However, estimates for E are used in most regional mapping studies. This study explores storage resource classification schemes and their evolution in understanding, the calculation of storage resources and the storage co-efficient. This is explored in terms of calculating E for CO2 storage sites, through flow modelling and analytical solutions.
