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...

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...

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...

Carbon Capture and Storage (CCS) and Carbon Capture Utilisation and Storage (CCUS) are increasingly vital in urban sustainability agendas for their role in mitigating climate change. CCS focusses on capturing CO₂ emissions from industrial and energy-related sources and storing them permanently...
