LONDON, UK, November 4, 2025 —Pace CCS, the global leader in carbon capture and storage (CCS) design, today announced the release of Version 1.1 of its industry-leading Pace CCS Corrosion Solution software.
This significant update provides enhanced capabilities for identifying and mitigating corrosion risks in CCS infrastructure, including improved predictions for gas phase and dense phase CCS pipelines and refrigerated shipping.The release comes at a critical time for the expanding CCS industry, where corrosion management remains one of the most significant technical challenges threatening pipeline integrity and project viability.
Pace CCS’s software is already relied upon by major CCS projects worldwide to ensure safe and corrosion-free operations.
Industry Context: Addressing a Critical CCS Challenge
Corrosion risks in carbon steel pipelines and wells arise due to aqueous phases induced by polar impurities in CO2 streams. Past CCS projects globally have experienced substantial corrosion-related challenges.The software specifically addresses key known issues:
- Identification of corrosion phases condensing under warm conditions in dense phase pipelines in the range of 35 to 60°C
- Quantification of the risk introduced by TEG dehydration systems
- Clarity on the relationship between water content and methanol
- Comprehensive predictions and chemical reaction prediction when mixing CO2 streams from different sources
What’s New in Version 1.1
The latest release introduces several groundbreaking capabilities that significantly impact risk assessment for gas phase and dense phase CCS pipelines and refrigerated shipping:
Improved thermodynamic model
Improved predictions of aqueous dewpoint and composition in the presence of polar molecules such as methanol and glycols.
Addition of amines
Expanded coverage of common CCS contaminants and their corrosive interactions.
Identification of water-soluble impurities
Enhanced detection of potentially corrosive compounds in CCS systems.
New laboratory data
Incorporates latest Pace CCS experimental findings on emergence of aqueous phases, improving prediction accuracy.Comprehensive Corrosion Prediction CapabilitiesThe
Pace CCS Corrosion Solution provides comprehensive and conservative predictions of all corrosion risk in CCS pipelines, storage vessels, and wells. The software incorporates advanced thermodynamic modeling fine-tuned for CO2 and polar compounds, reducing model uncertainty by up to 50% compared with typical thermodynamic models.The system leverages a genetic algorithm that can identify worst-case corrosion scenarios, processing millions of thermodynamic calculations to determine the most conservative design basis. This represents a novel approach in the field of corrosion prediction.The software’s capabilities include:
- Chemical reactions benchmarked to laboratory data, accurately predicting outcomes in 100% of cases
- Prediction of corrosion due to strong acids including sulfuric and nitric acid formation
- Assessment of corrosion due to free water during commissioning and transient operations
- Evaluation of solids formation from chemical reactions, including ammonium salts and elemental sulphur
- Analysis of corrosive aqueous phases induced by TEG, MEG, methanol, ethanol, propanol, and amines
- Consideration of over 4,000 possible chemical reactions between impurities in CO2 streams that can create corrosive compounds
Industry Applications and Impact
The Pace CCS Corrosion Solution supports multiple aspects of CCS development:
- Supporting development of a CO2 specification that ensures system integrity
- Supporting design by providing comprehensive understanding of corrosion risk
- Supporting operations by predicting the emergence of corrosive phases, including consideration of chemical reactions
