Integrated Techno-economic and Environmental Assessment of an Amine-based Capture
(Journal article; Peer reviewed, 2013)A systematic methodology for integrated techno-economic and environmental assessment of CCS value chains is presented and applied to assess the impact of the CO2 concentration on an amine-based post-combustion CO2 capture ... -
Integrated thermal storage and heat recovery of the CO2 refrigeration system for fishing vessels
(Chapter, 2020)The natural refrigerant CO2 is gaining an attraction for fishing vessels due to its compact units, negligible global warming potential (GWP), and non-toxic behaviour. Chilling and freezing onboard are energy-consuming ... -
Integrated thermal system for hydrogen and ammonia driven cruise ship
(Master thesis, 2022)Cruiseskipindustrien står overfor utslippsreguleringer på grunn av klimaendringer og global oppvarming. Tradisjonelt fossilt drivstoff som brukes til fremdrift og energibehov ombord på cruiseskip resulterer i et høyt ... -
Integrating ex-ante and prospective life-cycle assessment for advancing the environmental impact analysis of emerging bio-based technologies
(Peer reviewed; Journal article, 2023)Unlike the fossil-based alternatives, many emerging bio-based technologies are still at the early lab or pilot scale and are not representative of optimized industrial conditions. This makes a robust comparison of their ... -
Integrating impacts on climate change and biodiversity from forest harvest in Norway
(Journal article, 2018)Forest ecosystems provide a variety of services, from climate regulation to biodiversity conservation. Temporary land cover variations such as those related to forest management can contribute to climate change through ... -
Integrating LCA in the local energy planning for heat supply of buildings
(Master thesis, 2007)The objective of this study was to develop an approach to integrate LCA of different fuels and energy conversion technologies into the energy planning tool eTransport. Course LCA's for relevant energy commodities, ... -
Integrating life cycle and impact assessments to map food’s cumulative environmental footprint
(Peer reviewed; Journal article, 2020)Feeding a growing, increasingly affluent population while limiting environmental pressures of food production is a central challenge for society. Understanding the location and magnitude of food production is key to ... -
Integration of a cold thermal energy storage for air conditioning demand in a CO2 refrigeration system of a supermarket
(Master thesis, 2023)There is a significant transition in supermarket refrigeration, with a strong focus on reducing energy demand and installation costs. Generally, industry processes require cooling the most for short periods every day. The ... -
Integration of a Hydrogen Solution for Solving Power-Related Grid Problems
(Bachelor thesis, 2022)Elektrifisering og økende andel av fornybar energi har tydeliggjort behovet for nye energibærere. Dagens strømnett er designet for et økende behov på noen få prosent årlig. Dagens behov øker mye raskere enn dette. Den raske ... -
Integration of chemical looping combustion for cost-effective CO2 capture from state-of-the-art natural gas combined cycles
(Peer reviewed; Journal article, 2020)Chemical looping combustion (CLC) is a promising method for power production with integrated CO2 capture with almost no direct energy penalty. When integrated into a natural gas combined cycle (NGCC) plant, however, CLC ... -
Integration of Cold Thermal Energy Storage at a Pelagic Fish Processing Plant: A Modelling Approach
(Chapter, 2023)Energy intensive sectors such as food processing are paying more and more attention towards energy conservation and reducing their total carbon footprint. The energy demand of a pelagic fish processing plant has been ... -
Integration of gravity-fed evaporators in CO2 based heat-pump chillers
(Chapter, 2022)This study is carried out to model a gravity-fed evaporator for CO2 based heat-pump chillers. The gravity-fed evaporator loop consists of a separator, a downcomer, a heat exchanger, and a riser. The working principle is ... -
