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...

...rørledninger kommer på plass. Hvis funnene våre åpner for kald CO2-fangst, kan de dermed bidra til å framskynde CO2-lagring i Nordsjøen, sier forsker Kristin Jordal. CO2-fangst basert på nedkjøling har flere mulige bruksområder. Figuren viser hvordan CO2 kan fjernes fra “gassifisert” kull – det vil si kull som...

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...
In order to be able to compare and possibly rank different technologies for CO2 capture, and different means of integrating novel process units into power cycles with CO2 capture, it is vital to apply a consistent benchmarking methodology. A benchmarking will then provide a snapshot of the...
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...
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...
A fully automated multi-disciplinary design optimization procedure for a Francis turbine runner has been developed in a previous task of the Horizon2020-HydroFlex project. The design optimization was limited to blade design, with the goal of improving the hydraulic efficiency and torque, and...
... The paper presents the work of the Norwegian engineer Ægidius Elling (ref. Figure 1), from his gas turbine patent in 1884 to the first gas turbine in the world producing net power in 1903. It traces the subsequent patents, until his final experiments in 1932. Focus is placed on an engineer with a...
... “Innovative reactors” (based on chemical looping, membrane separation or sorption-enhanced processes) in power processes for CO2 capture appear to behave in such a way that some unconverted fuel could remain in the captured CO2-rich stream. This has the double drawback of adding impurities to the...
The CCS Midt-Norge project phase 1 has been a collaboration between Franzefoss Minerals, Statkraft Varme, Elkem Thamshavn, Wacker Holla Metall, Equinor Tjelbergodden and SINTEF. CO2 emissions from the industries in the project are around 1.5 Mt/year. Power consumption for capturing and liquefying...
Rapporten gjør en etterevaluering av en investering på 1,7 milliarder (løpende kroner) i nytt togradiosystem (GSM-R) i Norge i perioden 2003-2008. Kriteriene er produktivitet i utbyggingsfasen, effekter av investeringen (måloppnåelse), ytterligere virkninger, fortsatt relevans, løsningens...
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...
The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative computed tomography (CT) of an OSAS patient, the pre- and post-operative...
