AURORA latest review paper, developed in collaboration with researchers from SINTEF and NTNU, provides a comprehensive analysis of the CESAR1 solvent system. It collects and evaluates existing experimental data, highlights knowledge gaps, and outlines the necessary next steps in research to optimize the use of this innovative solvent for CO₂…

This publication, prepared by our project partners Cybernetica and SINTEF Industry, is a proceeding from the 34th European Symposium on Computer Aided Process Engineering and the 15th International Symposium on Process Systems Engineering (ESCAPE34/PSE24), held in Florence, Italy, from June 2-6, 2024. Solutions for advanced control of CO2 capture processes…

The last step of the CCUS full chain is represented by geological storage, when the CO2 is injected, via injection wells, into the deep sub-surface at a carefully selected site (such as a saline aquifer or a depleted oil/gas field). This work describes the methodology and the results adopted by…

The non-proprietary CESAR1 amine blend has been widely studied for use as a solvent for post-combustion CO2 capture. 1–5 Despite of its relative popularity in the solvent market, there are still many knowledge gaps connected to the stability of CESAR1. The mixture of 2-amino-2-methyl propanol (AMP, CAS 124-68-5) and piperazine…

Read our project partner\'s presentation on \"Exploring CCUS chains in Belgium and Greece based on open-access CESAR1 solvent capture technology\", by Anette Mathisen – (SINTEF), Hanne Kvamsdal (SINTEF), Stephane Jouenne (Totale Energies), Sabina Bigi (Sapienza University of Rome).

Abstract Solvent degradation during the CO2 capture process is known to reduce capture capacity, increase corrosivity, emissions and solvent toxicity, and complicate operation of the plant. The wide variety in degradation compounds include charged species, typically referred to as heat stable salt (HSS), amides, acids, nitrosamines, small volatile organic compounds,…

Abstract Amine-based absorption is currently the most advanced and cost-effective means of postcombustion CO2 capture among the different technologies that can be used (Dutcher et al., 2015). Much work has been done to reduce energy consumption, which constitutes one of the major penalties to the absorption process. Therefore, when it…

Abstract The reduction of carbon dioxide (CO2) emissions is a major global challenge in the fight against climate change. Among the various technologies available for post-combustion CO2 capture, amine-based absorption is currently considered the most advanced and cost-effective[1]. However, the absorption process incurs a significant energy penalty, prompting research efforts…

A reason why aqueous ethanolamine (MEA) is still considered a benchmark solvent for CO2 capture by some, despite of its relatively high energy consumption and relative instability compared to other solvents, is the abundance of knowledge and public data on MEA performance and chemistry. With more than 50 identified degradation…

ABSTRACT AURORA is a three and a half year HORIZON Europe project funded by EU and kicked off in January 2023. The participants of AURORA represent the following six European countries: Norway (5 partners), United Kingdom (1 partner), Belgium (1 partner), France (2 partners), Italy (1 partner), and Greece (2…
