Isdammen er Longyearbyens eneste drikkevannskilde, noe som gjør situasjonen sårbar. Høsten 2025 bestilte lokalstyret en helhetlig tilstandsanalyse av drikkevannskilden. Analysen inngår i lokalstyrets arbeid med å sikre en trygg og stabil vannforsyning til Longyearbyen i møte med både klimaendringer...
Et glasstak består av komplekse systemer med profiler, isolerruter og drenering, og krever derfor helhetlig planlegging fra tidlig prosjektfase. Av Kristin Elvebakk og Luise Schlunk, seniorrådgiver i SINTEF Glasstak kan gi flotte, lyse rom, men stiller høye krav til prosjektering. Både fukt, snø...
Norske smelteverk importerer over én million tonn kull og koks årlig etter at kullproduksjonen på Svalbard er avviklet. Avhengigheten reiser spørsmål om klima, etikk, forsyningssikkerhet og konkurransekraft i metallindustrien. Forskere peker på at kull fra Svalbard, brukt i en overgangsfase...
Arktis er i en ny og krevende sikkerhetspolitisk situasjon. Donald Trump vil ha Grønland. Svalbard kan dermed komme i spill, for en uforutsigbar Vladimir Putin kan fort få blod på tann. Norge må derfor styrke nærværet på Svalbard. Økt norsk bosetting og aktivitet på Svalbard er avgjørende for å...
The transition to electric vehicles is a cornerstone of global efforts to reduce carbon emissions, and dynamic wireless charging is instrumental in facilitating this shift by providing continuous charging capabilities. Renewed interest in this technology has emerged due to its reported advantages...
The electrification of heavy-duty vehicles requires megawatt-scale charging infrastructure, but distribution grid constraints and high investment costs pose significant challenges. This work presents a decision-support framework for evaluating and optimizing conditional connection agreements (CCAs...
Carbon capture, utilization, and storage (CCUS) play an increasingly important role in climate mitigation strategies by addressing industrial emissions and enabling pathways toward net-negative emissions. A key challenge lies in determining the pathway of captured CO2, whether through permanent...
Demand response can enable shifting the heat demand profile of consumers in district heating to improve utilization of variable waste-heat sources. Yet, effective demand response may rely heavily on the heating supply, the buildings and their heat control, and the participating share of the building...
Biochar and pesticides are likely to be increasingly used in combination in agricultural soils, yet their combined effects on climate change mitigation remain unexplored. This study presents an 8-month incubation experiment with different soil types (silt loam and sandy loam), biochars (corncob and...
This paper presents a design methodology for integrating an electrical energy storage unit into a hardware-in-the-loop (HIL) test rig for wave energy converters (WECs). Typically, the power production from WECs is characterised by pronounced fluctuations at low frequency and high peaks compared to...
Efficient capture and utilization of CO2 is the key to achieving carbon peak and neutrality. This study used the radial basis function neural network and extreme gradient boosting regression to build the regression models about CO2 adsorption uptake based on variable temperature and pressure swing...
This paper presents a simulation-based investigation of compatibility between grid forming converters with different control system implementations when operating in the islanded ac-grid of an HVDC-connected offshore wind farm. A system configuration with two HVDC-terminals connected to separate...
In Europe, most of the CO2 that needs to be captured is expected to be stored offshore due to the lack of social acceptability for onshore CO2 storage. This means that in the coming decades, infrastructure to transport several hundred million tonnes of CO2 from coastal locations to offshore storage...
Large language models (LLMs), such as ChatGPT and Gemini, have rapidly become an integral part of daily life, driven by their advanced conversational capabilities and versatility. Despite widespread adoption, understanding of users’ perceptions regarding the balance between beneficial assistance and...
This study investigates the potential of machine learning (ML) tools to enhance sub-hourly photovoltaic (PV) power simulations in high-latitude locations with snowy conditions. A comparative analysis was conducted between calibrated physical PV model chains and ML tools to assess their ability to...
This study examines how PV system orientation and design affect energy generation, self-consumption, and cost savings in a Nordic climate. Five different PV systems are analysed from the monitoring data of a Plus-Energy school in Oslo. The analysis shows that roof-mounted systems achieve higher...
The transport sector accounts for around 25 % of global energy use, considering both fuel production and consumption. To mitigate climate change, a fast decarbonization of transport is therefore often seen as a necessity, as advocated by the International Energy Agency in its Net Zero by...
Digestate, a key byproduct of anaerobic digestion (AD), holds residual methane potential (RMP) that must be stabilized or recovered to prevent greenhouse gas emissions after field use. Thermal hydrolysis (TH), typically a pretreatment for AD, improves biogas production. This study assesses RMP in...
Amidst the growing significance of renewable energy, this paper examines the asymmetric effects of renewable energy on electricity prices and transmission flows in the Nordics using hourly electricity data. Employing a novel panel asymmetric fixed-effects method, we quantify the non-linear impact of...
