This work presents the initial investigations of an Integrated Reforming Combined Cycle (IRCC) process with CO₂ capture using a membrane reformer. A geometrically generic 1-dimensional model of a membrane reformer has been implemented in Matlab 7.9. This model includes detailed balance equations for...

CO₂ capture and storage has a potential of reducing CO₂ emissions from large point sources such as fossil fuel power plants. CO₂ capture is associated with substantial capital expenditures, operational expenditures dominated by high energy use and potential operational restrictions on the underlying...

CEMCAP (http://www.sintef.no/cemcap/) is an EU Horizon 2020 project that aims at maturing CO₂ capture technologies suitable for retrofitting to existing cement plants by undertaking pilot-scale demonstration under industrially relevant conditions. Four capture technologies are being tested, analyzed...

The ongoing Preem CCS project investigates opportunities for CO₂ capture from the Preem refineries in Lysekil and Gothenburg, Sweden, with focus on the Lysekil refinery. The consortium members of this Norwegian-Swedish collaboration are Preem AB, Chalmers University of Technology, SINTEF Energy...

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...

A description is provided of the legal/regulatory situation, as of early December 2021, for CO₂ transport from Sweden/Preem AB to Norway/Northern Lights. CO₂ transport from Sweden to Norway for the purpose of geological storage under the seabed is since 2019 legal, thanks to the provisional...

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...

In view of the abundance of fossil fuels, hydrogen production with CO₂ capture could be a key transition technology for moving in the direction of a sustainable hydrogen-using society. An overview of technologies for hydrogen production from fossil fuels with CO₂ capture is provided in this paper...

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...

A description is provided of the legal/regulatory situation, as of early December 2021, for CO₂ transport from Sweden/Preem AB to Norway/Northern Lights. CO₂ transport from Sweden to Norway for the purpose of geological storage under the seabed is since 2019 legal, thanks to the provisional...

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...

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...

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...
