H2S removal technologies for maturing oil fields with sea water injection
(Master thesis, 2018)Enhanced oil and gas recovery is often performed with seawater injection in the well as pressure compensating mean. With it, potential challenges arise. Microbiological souring is considered a major contributor to the ... -
Habitat fragmentation amplifies threats from habitat loss to mammal diversity across the world’s terrestrial ecoregions
(Peer reviewed; Journal article, 2021)Global biodiversity is increasingly threatened by anthropogenic environmental change. While there is mounting evidence that habitat loss is a key threat to biodiversity, global assessments typically ignore additional threats ... -
Happier with less? Members of European environmental grassroots initiatives reconcile lower carbon footprints with higher life satisfaction and income increases
(Journal article; Peer reviewed, 2020)Scientists and policymakers recognize the need to address consumption and lifestyles in order to reconcile environmental and development agendas. Sustainability-oriented grassroots initiatives emerge bottom-up to create ... -
Harnessing thermoelectric power from transient heat sources: Waste heat recovery from silicon production
(Journal article; Peer reviewed, 2017)Thermoelectric generators (TEGs) are compact and robust devices for converting heat into electrical power. In this work, we investigate the response of a bismuth-telluride based TEG to the transient environment of a silicon ... -
Headline Environmental Indicators Revisited with the Global Multi-Regional Input-Output Database EXIOBASE
(Journal article; Peer reviewed, 2018)Environmentally extended multiregion input‐output (EEMRIO) databases are used to quantify numerous environmental pressures and impacts from a consumption perspective. However, for targeted communication with decision makers, ... -
Health benefits, ecological threats of low-carbon electricity
(Journal article; Peer reviewed, 2017)Stabilizing global temperature will require a shift to renewable or nuclear power from fossil power and the large-scale deployment of CO2 capture and storage (CCS) for remaining fossil fuel use. Non-climate co-benefits of ... -
Heat and mass transfer in gas-solid packed beds
(Doctoral theses at NTNU;2018:137, Doctoral thesis, 2018)The present thesis probes the heat and mass transfer phenomena in packed bed of particles. The gap in literature for realistically packed dense particle packings is explored, following which a new methodology to study ... -
Heat Capacity Measurements of Porous Materials at Cryogenic Temperatures
(Master thesis, 2012)In the search for new technology, new materials are prerequisite for major breakthrough. One of these classes of functional materials is the metal-organic framework (MOF). The MOFs offer higher surface areas because of its ... -
Heat Exchange in a Fluidized Bed Calcination Reactor
(Master thesis, 2008)Sorption Enhanced Steam Methane Reforming (SE-SMR) is a novel way of reforming natural gas to high purity hydrogen gas with in-situ CO2 capture by the introduction of a CO2 sorbent. The process is carried out in two steps. ... -
Heat generation and conduction in combined ultrasound imaging and therapy transducers
(Master thesis, 2017)In this thesis, the heat sources and heat transfer in high power, multifrequency transducers to be used for both ultrasound imaging and mediation of drug delivery, are studied. Electrical energy is converted into acoustic ... -
Heat pump systems adapted to highly-insulated office buildings - Comparison between simulations and field measurement
(Master thesis, 2016)The temperature in the atmosphere is rising as a cause of human influence, and it was found that the building sector in 2012 emitted 18.4 % of the greenhouse gas (GHG) emissions on the planet (Pachauri et al., 2014). A ... -
Heat pump/chiller system for centralized kitchens in India
(Chapter, 2020)A heat pump unit using CO2 as working fluid is designed to meet not only a part of the heating demand in the centralised kitchen at The Akshaya Patra Foundation, Bengaluru, India, but also the entire cooling demand to ... -
Heat Pumping Systems for Chilling of Fish - Use of Impingement Freezer for Super Chilling
(Master thesis, 2010)Superkjøling er en teknologi som åpenbart har klare fordeler. Det å kunne forlenge holdbarheten samtidig som en bevarer kvaliteten og i tillegg øke effektiviteten på produksjonen, vil gi en gevinst for både forbruker og ... -
