(ZEN Report;, Research report, 2022)This document outlines the definition, key performance indicators (KPI) and assessment criteria for the Research Centre on Zero Emission Neighbourhoods in Smart Cities (ZEN Research Centre). This third version of the ZEN ... -
The unequal distribution of household carbon footprints in Europe and its link to sustainability
(Peer reviewed; Journal article, 2020)The distribution of household carbon footprints is largely unequal within and across countries. Here, we explore household-level consumption data to illustrate the distribution of carbon footprints and consumption within ... -
Shifting economic activity to services has limited potential to reduce global environmental impacts due to the household consumption of labour
(Peer reviewed; Journal article, 2020)The tertiary (or 'service') sector is commonly identified as a relatively clean part of the economy. Accordingly, sustainable development policy routinely invokes 'tertiarization'—a shift from primary and secondary sectors ... -
A Numerical Investigation of Turbulent Combustion in Pool Fires using OpenFOAM
(Master thesis, 2022)Brann er en faretype som kan p˚aføre store økonomiske tap og føre til tap av liv. Økt kunnskap rundt nøyaktig modellering av brann er ett av de første stegene for ˚a f˚a en bedre innsikt i dens mekanismer og gir bedre ... -
A Techno-Economic Model for Benchmarking the Production Cost of Lithium-Ion Battery Cells
(Peer reviewed; Journal article, 2022)In response to the increasing expansion of the electric vehicles (EVs) market and demand, billions of dollars are invested into the battery industry to increase the number and production volume of battery cell manufacturing ... -
Nullutslippsnabolag i smarte byer: Definisjon, vurderingskriterier og nøkkelindikatorer: Versjon 3.0
(Research report, 2022)Denne rapporten beskriver definisjonen, nøkkelindikatorer og vurderingskriterier som benyttes i forskningssenteret for nullutslippsområde i smarte byer (ZEN senteret). Denne tredje utgaven av ZEN-definisjonen bygger på ... -
Dispersion of light traveling through the interstellar space, induced and intrinsic Lorentz invariance violation
(Peer reviewed; Journal article, 2021)Theoretical models and experimental observations suggest that gamma-ray bursts (GRB) and high-energy neutrino bursts travelling through the interstellar space may reach the Earth at different speeds. We propose and study ... -
Heat to Hydrogen by Reverse Electrodialysis—Using a Non-Equilibrium Thermodynamics Model to Evaluate Hydrogen Production Concepts Utilising Waste Heat
(Peer reviewed; Journal article, 2022)The reverse electrodialysis heat engine (REDHE) is a promising salinity gradient energy technology, capable of producing hydrogen with an input of waste heat at temperatures below 100 °C. A salinity gradient drives water ... -
A time-quantitative analysis of calorie flows within the global food supply and the calorie footprint of nations - opportunities for increasing food availability and enhancing food security.
(Master thesis, 2022)Motivert av interessen for å finne måter å øke tilgjengeligheten på mat for å mate befolkningen i 2050 samtidig som den møte den økende globale etterspørselen etter avlinger til andre formål, presenterer dette arbeidet en ... -
An environmental assessment of the electrification of construction machinery
(Master thesis, 2022)En rask overgang til mindre utslippsintensive teknologier er nødvendig for å dempe effektene av klimaendringer. Byggeaktiviteter er en betydelig kilde til utslipp over hele verden, og en stor bidragsyter til dette er den ... -
Towards a LCA Database for the Planning and Design of Zero-Emissions Neighborhoods
(Peer reviewed; Journal article, 2022)The integration of science-based knowledge on greenhouse gas (GHG) emissions into practice-based neighborhood design and planning is key to inform and implement climate mitigation strategies. LCA is a method that is commonly ... -
Spatial variation in household consumption-based carbon emission inventories for 1200 Japanese cities
(Peer reviewed; Journal article, 2020)Given that national pledges are likely insufficient to meet Paris greenhouse gas (GHG) reduction targets (Fawcett et al 2015 Science 350), increasingly actors at the city and state level are looking for options on how local ... -
Influence of geometrical parameters on the hysteresis of flutter onset in confined configurations
(Peer reviewed; Journal article, 2022)The interaction between a flow and a flexible structure can provide fascinating insight into the vortex shedding phenomenon and any propagation and mixing characteristics, which relate to a plethora of applications such ... -
Numerical approaches for thermochemical conversion of char
(Peer reviewed; Journal article, 2022)This paper gives a review of the current state of the art for numerical simulations of char conversion. In particular, it presents models that have been developed to describe the physical and chemical phenomena that ... -
Estimating CO2 Emissions for 108,000 European Cities
(Peer reviewed; Journal article, 2022)City-level CO2 emissions inventories are foundational for supporting the EU's decarbonization goals. Inventories are essential for priority setting and for estimating impacts from the decarbonization transition. Here we ... -
Performance Improvements of Standalone Liquid Air Energy Storage
(Doctoral theses at NTNU;2022:375, Doctoral thesis, 2022)Due to the threat of climate change, our energy systems tend to adopt lower-carbon energy sources, such as renewables. In addition, our energy systems are likely to follow another trend from very large centralized industrial ... -
Geo-referenced building stock analysis as a basis for local-level energy and climate mitigation strategies
(Peer reviewed; Journal article, 2022)A geo-referenced building stock model was used to analyse the energy and climate performance of the Knowledge Axis in Trondheim, Norway, by 2050. Strategies for energy upgrades, construction of more energy-efficient new ... -
Monitoring and simulating material cycles and emissions at multiple scales: Case studies for aluminium
(Doctoral theses at NTNU;2022:386, Doctoral thesis, 2022)Metal cycles form the backbone of our modern societies but are also responsible for a large part of the anthropogenic greenhouse gas (GHG) emissions. The transition towards a more sustainable socio-economic metabolism will ... -
Evaluation of MBTSA technology for CO2 capture from waste-to-energy plants
(Journal article; Peer reviewed, 2022)Moving bed temperature swing adsorption (MBTSA) is a promising technology for CO2 capture from flue gases. In a MBTSA unit, a selective adsorbent material is circulated between a low-temperature stage where it removes CO2 ... -
