The application of CO2 capture by liquefaction has been investigated for an integrated gasification combined cycle (IGCC). Two configurations of the process are developed–one supplying CO2 at conditions suitable for pipeline transport and the second one producing liquid CO2 suitable for ship...
The improvement in thermal efficiency for coal to power processes is increasingly important due to concerns on CO2 emissions. This paper presents a systematic study on direct combustion coal to power processes with respect to thermodynamic, technical and economic factors. Traditional exergy analysis...
Four different post-combustion capture technologies are compared for the same NGCC (electric efficiency 58.1% without CO2 capture). The technologies are aqueous amine, polymeric membranes, a low temperature sorbent and Ca-looping. The effect of 40% Exhaust Gas Recirculation (EGR) is compared for all...
Eramet Norway Sauda, Hydro, Gassco/Equinor and Haugaland Næringspark (HNP) have joined forces in a CCS cluster to evaluate benefits from cooperating on transport of captured CO2 to a storage terminal. Total CO2 emissions in the cluster were in 2022 1.5 million tonnes, which can be expected to...
Denne rapporten oppsummerer funn og analyse fra CLIMIT idéstudie «Haugaland CCS». Studiet har tatt utgangspunkt i hydrogenproduksjon fra naturgass med CO2-fangst ved Haugaland Næringspark, og kartlagt potensiell regional bruk av hydrogen i tillegg til stor-skala eksport. Hydrogen for avkarbonisert...
The Natural gas Combined Cycle (NGCC) with post combustion capture using liquid solvents may in some cases be of interest to design with a flexible steam bottoming cycle, so that it can operate both with and without CO2 capture. It is then important that the choice of the low pressure (LP) steam...
Aluminum production contributes to global CO2 emissions both due to the production process itself and due to the generation of electric power required for aluminum production. A concept is presented for increasing the CO2 concentration in the aluminum exhaust from ∼1% to ∼5% through the feeding of...
A technical evaluation of CO2 capture technologies when retrofitted to a cement plant is performed. The investigated technologies are the oxyfuel process, the chilled ammonia process, membrane-assisted CO2 liquefaction, and the calcium looping process with tail-end and integrated configurations. For...
Reactive absorption of CO2 with MEA (monoethanolamine) has been established as the preferred reference technology in benchmark studies of novel post combustion CO2 capture technologies. However, recent advances in solvents tailored for CO2 capture warrant an updated reference for consistent...
This paper evaluates the potential of post-combustion CO2 capture from a natural gas combined cycle (NGCC) through the use of solid sorbents at high temperatures. Experimental deactivation and residual sorption capacity parameters for various sorbents reported in the literature, as well as from own...
Calcium looping is a post-combustion technology that enables CO2 capture from the flue gases of industrial processes. While considerable studies have been performed at various levels from fundamental reaction kinetics to the overall plant efficiency, research work on techno-economic analyses of...
A novel hybrid concept is proposed, combining Pd-alloy membrane and low temperature separation technology, to produce pure H2 from gasified coal and capture the main part of the generated CO2. 75% of the H2 produced from gasification and water-gas shift is separated from the shifted syngas through H...
CO2 Capture and Storage (CCS) is today seen as a key technology to cut carbon emissions in many hard-to-abate sectors such as energy-intensive processing industries and the waste sector. Although CO2 capture is technically possible, key challenges for realizing CCS persist. Over the past decade, CCS...
A main hurdle for realizing the IGCC with CO2 capture is the lack of gas turbines capable of burning hydrogen in an environmental-friendly, yet energy-efficient manner. With currently proposed combustion schemes an efficiency penalty is caused by the preparation (separation and compression) of the...
An investigation is made of two different integration options for a MEA post-combustion CO2 capture unit in a natural gas combined cycle (NGCC). Thereafter, a study is made of the part load operation of the NGCC with and without CO2 capture. The considered integration options were (1) steam...
A consistent and transparent benchmarking methodology is required for comparison and ranking of different technologies for CO2 capture, and also for evaluation of different means of integrating novel capture process units into power cycles. A novel benchmarking methodology is presented in this work...
The ECCO project has been a three-year collaboration project under the EU 7th framework program for research. The main objective of ECCO has been to facilitate strategic decision making regarding early and future implementation of CO2 Capture and Storage (CCS) value chains. The ECCO project has...

Capture conditions for CO2 vary substantially between industrial point sources. Depending on CO2 fraction and pressure level, different capture technologies will be required for cost- and energy-efficient decarbonisation. For decarbonisation of shifted synthesis gas from coal gasification, several...
Aluminium smelting plants typically emit 1.5 tonne of CO2 per tonne of aluminium produced. However, the CO2 concentration in the exhaust is very low, typically below 1%, since large quantities of air are employed for cooling of the electrolytic cells and for cooling of the raw gas before gas...
