The following presentation will be based on preliminary results obtained in the KPN project A GREEN Sea. On the background of the project objective, “identify, mature and evaluate new technologies and concepts for acid gas removal (AGR) avoiding CO₂ emissions to air and use of harmful chemicals...

We present an approach for assessing the effect of using scenario tree approximations of limited size to represent the probability distribution of uncertain variables in stochastic hydropower scheduling models. The aim of reducing the size of the tree is to reduce the computation time. The scenario...

Stress-induced electrochemical degradation (SIED) structures are likely initiated at the surface of the conductor screen of insulated XLPE cables with stranded aluminum conductors due to water ingress and corrosion. In time such structures initiate severe vented water treeing which...

I denne rapporten diskuterer vi om det er en miljøgevinst av å øke den installerte effekten (MW) i norsk vann¬kraftproduksjon. Dersom en installerer nye aggregat med større kapasitet vil en få økt kraft¬produksjon som følge av redusert flomtap og bedre virkningsgrad. Dette gir en miljøgevinst siden...

Biomass is the only renewable carbon source and can therefore be used for production of fuels and chemicals which are made from oil and natural gas today. Biofuels seem to be a promising alternative for today's fossil fuels since they can substitute more or less directly fossil fuels in the existing...

I Samkjøringsmodellen kan man spesifisere prisavhengig forbruk. Dersom prisen øker reduseres van¬lig¬vis forbruket. Denne forbruksresponsen har vært momentan i den forstand at prisen i inneværende uke er avgjørende for forbruksnivået. I denne rapporten dokumenteres en ny funksjonalitet hvor forbruks...

This report is deliverable number D 3.2.8 in the CREATIV project. In a time of fewer resources and rising energy prices savings in energy costs are an important goal for the food industry. This study analyses the potential of cold thermal energy storage applying an indirect carbon dioxide system to...

This report gives guidelines for risk based maintenance and reinvestment management of electricity distribution assets. The report is one of the deliverables from the RISK DSAM project, and presents a summary of important results from the project. The aim of the report is to provide insight in risk...

Det har oppstått betydelige skader på ledninger og andre komponenter i et koblingsskap til en generator pga. varmgang i tilkoblingsledninger fra viklinger til tilkoblingsskinner i skapet. Skapet var tett og uten kjøling. To parallelle ledere på 185 mm2 ble belastet med en merkestrøm på 1905,3 A og...

CO₂ kann in verschiedenen kältetechnischen Anwendungen vorteilhaft eingesetzt werden, sei es als Kältemittel in Kaskadesystemen auf der Niedertemperaturseite, in Wärmepumpenanlagen zur Heißwasserbereitung sowie in herkömmlichen kältetechnischen Anlagen, wobei auch der Einsatz als Kälteträger in...

IEA WIND R&D Task 25 on "Design and Operation of Power Systems with Large Amounts of Wind Power" collects and shares information on wind generation impacts on power systems, with analyses and guidelines on methodologies. This paper summarizes the main results from the report published on January...

Targets are set for a massive installation of offshore wind. In Europe alone the industry suggests 40 GW by 2020 and 150 GW by 2030 as viable. The development is ongoing, but in an early stage. Only approx. 2 GW of offshore wind have so far been installed in Europe, and all relatively close to shore...

Transmission lines are critical infrastructures, but frequently contested especially at the local level, bylocal communities. The role of public engagement in processes pertaining to specific transmission lineprojects is an under-researched, yet important topic that this paper seeks to discuss by...
