Waste tyre gasification Processes: A bibliometric Analysis and comprehensive review
(Peer reviewed; Journal article, 2024)Waste tyres are a significant environmental problem due to their large volume and the difficulty of disposing of them safely. Waste tyre gasification is one of the key thermochemical routes for converting waste tyres into ... -
Gasskraftverk med CO2-håndtering - Studie av alternative teknologier
(Research report, 2002)Rapporten dokumenterer en studie som beskriver og sammenligner 12 ulike teknologier for gasskraftverk med CO2-håndtering. Merkostnaden for å fjerne CO2 i forbindelse med elektrisitetproduksjon er i studien beregnet til ... -
Towards a circular phosphorus economy in Norway - Strategies for integrating agriculture and aquaculture at multiple scales
(Research report, 2023)Phosphorus is a building block for all life and therefore plays an essential role in food production. Currently, large amounts of phosphorus enter the Norwegian food system from abroad in the form of mineral fertilizer, ... -
What Is the Impact of Accidentally Transporting Terrestrial Alien Species? A New Life Cycle Impact Assessment Model
(Peer reviewed; Journal article, 2024)Alien species form one of the main threats to global biodiversity. Although Life Cycle Assessment attempts to holistically assess environmental impacts of products and services across value chains, ecological impacts of ... -
Paving the way for sustainable decarbonization of the European cement industry
(Peer reviewed; Journal article, 2024)Cement production is a main source of carbon emissions. Decarbonization options exist, but their climate change mitigation potential, feasibility and environmental implications are still unclear. Here we assess 15 ... -
PV-to-Heat: Control and Monitoring Methods
(Master thesis, 2024)Mange afrikanske land har en økende befolkning og økonomi. Imidlertid er energiproduksjonen regelmessig ikke tilstrekkelig, noe som fører til strømbrudd i byene og distriktene har ikke tilgang til strøm. Mindre enn 10 % ... -
Water-Repellent Surfaces Consisting of Nanowires on Micro-Pyramidal Structures
(Peer reviewed; Journal article, 2019)Super-repellent surfaces are relevant for several practical applications, such as water collection and self-cleaning and anti-icing surfaces. However, designing surfaces that can maintain their super-repellency when the ... -
Radiative forcing geoengineering causes higher risk of wildfires and permafrost thawing over the Arctic regions
(Journal article; Peer reviewed, 2024)Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use an Earth System Model to analyse the response ... -

van der Waals induced ice growth on partially melted ice nuclei in mist and fog
(Journal article; Peer reviewed, 2023)Ice nucleation and formation play pivotal roles across various domains, from environmental science to food engineering. However, the exact ice formation mechanisms remain incompletely understood. This study introduces a ... -
Towards EU climate neutrality: Progress, policy gaps and opportunities
(Book, 2024)Based on an assessment of more than 80 indicators, we found that more efforts are needed across all sectors to achieve the EU climate objectives from 2030 to 2050, and particularly in buildings, transport, agriculture and ... -
Life cycle assessment of hard carbon production in Norway using biomass (sawdust) as precursor
(Master thesis, 2024)Hard karbonproduksjon har fått mer oppmerksomhet de siste årene på grunn av verdien i alkali-ion-batterier. Dens fordelaktige egenskaper i natriumion-batterier gjør det mulig for bat- produksjonen for å være mer bærekraftig ... -
Between the lines: Life cycle impact assessment models of collision and electrocution impacts of power lines on bird diversity in Norway
(Journal article; Peer reviewed, 2024)The expansion of the electric grid is inevitable. Renewable energy is on the rise, and new transmission lines must be built to link new electricity production facilities with the local network. In addition, higher electricity ... -
Relaxation phase during droplet impact on superhydrophobic surfaces with high contact angle hysteresis
(Peer reviewed; Journal article, 2023)The droplet impact process on a solid surface is divided into a spreading phase where the droplet reaches the maximum deformation followed by a retracting phase. However, in the case of surfaces with high contact angle ... -
A Hybrid Data-Driven Metaheuristic Framework to Optimize Strain of Lattice Structures Proceeded by Additive Manufacturing
(Peer reviewed; Journal article, 2023)This research is centered on optimizing the mechanical properties of additively manufactured (AM) lattice structures via strain optimization by controlling different design and process parameters such as stress, unit cell ... -
CO2 Capture and Enhanced Hydrogen Production Enabled by Low-Temperature Separation of PSA Tail Gas: A Detailed Exergy Analysis
(Journal article; Peer reviewed, 2024)Abstract Hydrogen from natural gas reforming can be produced efficiently with a high CO2 capture rate. This can be achieved through oxygen-blown autothermal reforming as the core technology, combined with pressure-swing ... -
