“…Thermal energy storage could be the key to overcoming fossil fuel dependency, which can be considered as a consequence of the difficulty of harvesting and storing energy from renewable sources [17]. In particular, the authors believe that seasonal energy storage will be a strategic technology to increase energy and food security [43,44] in the off-grid communities of circum-arctic countries.…”

Highlights-First-time design of borehole thermal energy storage in a subarctic climate -Best scenarios provide 50 % solar fraction and 60 % heat recovery at the 3 rd year -Annual savings of 7 000 l of diesel and 19 tonnes of equivalent CO2 are achieved -A novel type of borehole connection reduces advection heat loss by 60 % -Underground storage is a key technology towards energy and food security in the Arctic ABSTRACTThe development of renewable energy technologies in the Arctic faces technical barriers mainly related to extremely cold temperature. Moreover, storage issues to bridge the gap between supply and demand are more compelling than in temperate climates. Can underground thermal energy storage be efficiently used in such a cold environment to offer a viable seasonal storage alternative? This working hypothesis was tested by designing and simulating for the first time a borehole thermal energy storage facility in a subarctic climate. A system comprising a 1000 m 2 gross solar area and one hundred 30-m-deep borehole heat exchangers was simulated in TRNSYS to cover part of the heating demand of a pumping station that supplies drinking water in Kuujjuaq (Northern Québec, Canada). The Nunavik capital is characterized by more than 8000 heating degree days below 18 ºC and average spring-summer solar radiation of 4.6 kWh m -2 d -1 . Despite the presence of discontinuous scattered permafrost in the area, the study site is free of frozen ground, likely due to a talik that developed around a nearby lake. A number of scenarios reveal that solar fraction of 45 to 50 % and heat recovery of more than 60 % can be achieved by the 3 rd year of operation, resulting in annual savings of 7 000 l of regular diesel consumption. A 50-years life-cycle cost analysis demonstrates that a specific incentive program can guarantee similar net present cost and levelized cost of energy compared to the current dieseldependent situation, or better if electricity comes from renewable source. An additional 10 % loss of thermal energy occurs when groundwater advection is a factor. FEFLOW simulations demonstrate that square-shaped storage together with a newly-proposed borehole connection design can reduce advection heat loss by 60 % and improve the overall performance of the system. This work validates the technical viability of underground thermal energy storage in subarctic climates and indicates it could help reduce fossil fuel consumption in

“…Researchers in the different projects also cross-collaborate: for example, the engineers in SEQINEQ (energy) are looking at how to heat greenhouses more efficiently in collaboration with the nutritionists and geographers in NIQILIRINIQ (food security). These teams also work closely together to gain a better understanding of the particularities of greenhouses in a Northern context, in terms of both physical and social aspects (Lamalice et al 2018).…”

“…Further, environmental issues linked to greenhouse gardening were studied, as fertilization of the local soil used in the garden beds, greenhouse energy optimization to increase the length of the growing season, and mitigation of carbon dioxide emissions. Those questions and their results are discussed in Lamalice et al (2018). Although community greenhouses and gardening projects cannot solve the multiple issues linked to food insecurity in the region, they can be considered as one element of a community-based strategy to increase food independence in the North.…”

Adjusting to global climate and socio-environmental changes has become a major issue for many societies, especially in the Arctic. Many Inuit wish to better understand the changes taking place. In 2013, an international Observatory of Human-Environment Interactions (OHMi) was established in Nunavik to identify these changes, study their cumulative impact on the socio-ecosystem and to help develop adaptation measures to improve the well-being of Inuit communities. To this end, a team of academics and local Inuit partners joined forces to develop an integrated, interdisciplinary, collaborative research program. Using a participatory action research (PAR) approach, the OHMi Nunavik set the following research priorities: elder-youth knowledge transmission, northern agriculture, preservation of Inuit culture, language and identity, protected areas, mining employment, natural hazards and risks, and wildlife vulnerability. By strengthening the collaborations between multidisciplinary Canadian and French research teams, the OHMi Nunavik program integrates local and scientific knowledge both in planning the research and in disseminating the results. RÉSUMÉ L'adaptation aux changements climatiques et socio-environnementaux est devenue un enjeu majeur pour de nombreuses sociétés, notamment dans l'Arctique. De nombreux Inuit souhaitent mieux comprendre les changements qui se produisent. En 2013, un Observatoire international sur les interactions Homme-Milieu (OHMi) a été mis en place au Nunavik pour identifier ces changements, étudier leur impact cumulatif sur le socio-écosystème et pour aider à élaborer des mesures d'adaptation afin d'améliorer le bien-être des communautés inuit. À cette fin, une équipe d'universitaires et de partenaires Inuit locaux ont uni leurs forces pour développer un programme de recherche concerté, intégré et interdisciplinaire. En utilisant une approche de recherche-action participative, l'OHMi Nunavik a défini les priorités de recherche suivantes: transmission des connaissances entre les aînés et les jeunes, agriculture nordique, préservation de la culture, de la langue et de l'identité inuit, aires protégées, emplois dans les mines, risques naturels et vulnérabilité de la faune. En renforçant les collaborations entre les équipes de recherche multidisciplinaires canadiennes et françaises, le programme de l'OHMi Nunavik intègre les connaissances locales et scientifiques dans la planification de la recherche et la diffusion des résultats.
