CO2 Capture
Contact person
Solvent technology
Overall objective:
To enhance CO2 capture efficiency by increasing cyclic capacity through solvents engineered into liquid-solid phase change in the presence of CO2 at process conditions and to develop a dynamic model to be used for evaluation of solvents under transient conditions.
Contribution to one or more of the overall goals/objectives of BIGCCS
A tangible objective of BIGCCS is 50% reduction of CO2 capture cost; increased cyclic capacity of CO2 absorbent is directly coupled to capture cost reduction. Dynamic model of a capture process will enhance the reliability. This task contributes to the scientific and technological objective of BIGCCS by knowledge development through high quality research which has been disseminated through conferences and journal publications. This task currently hires a PhD candidate in line with the recruitment objective of BIGCCS.
Achievements thus far
- Absorbents that improve capture efficiency due to precipitation at process condition have been identified. Characterization studies have been carried out on the precipitate and the precipitating systems. Initial results have shown that precipitation at process condition results to significant reduction in energy number.
- A dynamic process flowsheet model has been developed in Matlab and also linked to the CO2SIM (SINTEF in-house simulation tool for absorption based processes) framework. Dynamic pilot plant campaign is being concluded.
Innovative membrane technologies
Overall objective:
To develop dense inorganic membranes for pre-combustion decarbonisation processes, e.g., steam-methane reforming, and hybrid membranes for post-combustion CO2 separation.
Contribution to one or more of the overall goals/objectives of BIGCCS
The membrane technologies investigated are core components in several of the pursued CO2 capture schemes. Therefore, membrane performance in terms of flux, selectivity and stability under realistic operation conditions directly address the overall project goals related to capture rate, cost reduction and fuel-to-electricity efficiency.

Hydrogen Combustion Technologies
The overall objective of the task is to provide clean and efficient solutions for CO2 capture technologies based on combustion of hydrogen and hydrogen-rich synthetic gaseous fuels
Task 1.3 contributes to the overall objectives of BIGCCS through:
- Advancement in the fundamental understanding of the physical processes that characterize combustion of hydrogen, including flame propagation and pollutant formation, at both laminar and turbulent conditions, as opposed to combustion of more conventional gas turbine fuels (natural gas, fuel oil).
- Optimization of the hydrogen fuel injection method and of its mixing pattern within the oxidant stream, while still conserving operational safety and fuel efficiency.
- Acquisition of detailed knowledge about flame propagation and stabilization characteristics, with specific focus on flashback (upstream flame propagation against the direction of the main reactant’s flow), for hydrogen-air flames.
- The close collaboration with world-renowned combustion research groups at Sandia National Laboratories (Livermore, California), DLR (Stuttgart, Germany), TU Munich (Munich, Germany) and Princeton University (Princeton, New Jersey) strengthen considerably the scientific level and the international visibility of the research performed within the task.
Addressing point 1) is of fundamental importance to improve the confidence in the utilization of hydrogen-rich mixtures as main fuel for large-scale, clean and highly efficient power generation with minimal CO2 footprint. Solving the issues related to point 2) and 3) above will enable the deployment of pre-combustion CO2 capture schemes based on new, highly efficient (no fuel dilution with N2 required!) hydrogen combustion equipment for gas turbine engines.This is a necessary step within the pre-combustion route to CCS because using existing combustion equipment is presently hindered by the peculiar combustion properties of hydrogen (high reactivity, high diffusivity) compared to more traditional hydrocarbon fuels, for which existing equipment has been designed.
Task 1.3 achievements so far:
- Flashback of hydrogen-air turbulent flame in ducts is characterized, using Direct Numerical Simulation (SINTEF/Sandia NL) and high-definition laboratory experiments (TU Munich), a previously unknown feature of near-wall flame propagation is discovered and severe limitations of a widely used boundary layer flashback model from Lewis and Von Elbe are exposed.
- A novel analytic flame channel-flashback model is proposed and validated (SINTEF/Sandia NL).
- A new fuel injection device, based on a porous steel support, a H2-selective membrane and a ceramic diffusor layer, is being investigated, both numerically and experimentally, in order to solve well-known issues related to hydrogen injection through conventional fuel injection methods (nozzles) and the concentrated point sources of the highly reactive fuel species (SINTEF/DLR).

Application to industry and offshore
Overall objective:
To assess and evaluate the potential for CCS in other industries and offshore.
Contribution to one or more of the overall goals/objectives of BIGCCS
- Assessments of advanced CO2 capture techniques to the benefit of other energy intensive industries and offshore applications
- Identifying industrial CO2 value chain that could potentially result in 50% cost reduction
Task 1.5 achievements thus far
- Developed methodologies for systematic process design and evaluation of industrial CO2 capture processes.
- Developed low temperature CO2 capture process for H2 production from coal that results in an efficiency improvement of 2% points and cost reduction of approximately 30%.
- Experimentally verified the potential for retrofitting refinery furnaces with oxy-combustion for a variety of liquid and gaseous fuels. Results indicate that furnaces can be retrofitted without an expensive rebuild.
- Numerical simulations performed that showed the potential for retrofitting existing furnaces to H2 combustion. The results indicate that, contrary to expectations, NOx emissions are reduced or remain the same. This has been preliminary verified in lab experiments. Detailed lab testing is ongoing.
Integrated assessment
Overall objective:
To evaluate the potential of CO2 capture technologies (solvents, sorbents, membranes) and, based on unit modeling and process simulations, point out the direction for further research on these capture technologies.
Contribution to one or more of the overall goals/objectives of BIGCCS
The conclusions from task 1.6 research have throughout the lifetime of BIGCCS been directly comparable to the tangible objectives of 90% CO2 capture rate and fuel-to-electricity penalty of 6 percentage points. Beginning from 2014, increased focus will also be on the requirements that must be put on CO2 capture for achieving a 50% CO2 capture cost reduction compared to most mature technologies.
Task 1.6 achievements thus far:
- Investigation of different means of CO2 enrichment in the exhaust of gas turbine-based power processes, including collaboration with Task 1.4 on gas turbine combustion with low oxygen concentrations.
- Investigations of calcium looping (Ca-looping) for post-combustion capture in natural gas combined cycles (NGCC). A systematic approach has been employed where different measures for process efficiency improvement have been applied, covering both power process and Ca-sorbent improvements. The best cases reach an electric efficiency penalty of around 6%-points, i.e. they respond to one of the BIGCCS objectives.
- The fundamental calculations for a novel thermodynamic benchmarking methodology have been conducted, meaning that the inherent thermodynamic penalties of CO2 capture have been determined (figure 1). The pillars in figure 1 show the minimum penalty for different CO2 capture routes and different fuel compositions imposed by the laws of thermodynamics. In addition to these penalties come the penalties imposed by technological constraints (e.g. materials limitations, process unit irreversibilities) and those imposed by economic constraints.
Looping technologies
Overall objective:
To increase the knowledge and technology basis in CLC reactor system design and oxygen carrier material development in order to bring CLC technology to the next level of maturity.
Contribution to one or more of the overall goals/objectives of BIGCCS
Recent studies indicate that one of the main benefits with CLC technology is the potential low CO2 capture efficiency penalty. As such, it contributes directly to one of the main objectives of BIGCCS which is to develop knowledge and technology with potential of penalty less than 6 %-points.
Task 1.7 achievements thus far
Based on material screening and testing the task has recommended an oxygen carrier material based on manganese oxide and calcium to be developed further within the project. The task has acquired flexible equipment for oxygen carrier particle production which is being used to formulate optimal production methodology. A fluidized bed reactor of about 3 kW power has been developed, specifically to be used for the first testing of new oxygen carrier materials. At a larger scale, of about 150 kW, the project has developed and built a second-generation fluidized CLC reactor system aiming at high fuel conversion and operational flexibility. At this size, results will be more realistic and contribute to higher confidence before technology up-scaling.
