北极高海拔地区的许多偏远土著社区依靠柴油或其他化石燃料发电，但进口燃料的高成本限制了家庭购买食物和足够住房的能力，进而削弱了北极地区的生活条件。虽然格陵兰公用事业公司 Nukissiorfiit 产生的能源大约 65% 来自可再生能源，但近 70% 的公共和私人电力和热能消耗是基于化石燃料的 Naalakkersuisut (2018) [1]。与社区合作实现向可再生能源的过渡可以加强当地能源自力更生，并以拥抱其文化遗产的方式建设技术能力。本文研究了格陵兰岛卡纳克狩猎/渔村采用太阳能的初步可行性，该村环境充满挑战，几乎没有风能或水力发电潜力。机组承诺优化模型用于评估可能的能源项目的可行性，其中包括 Qaanaaq 能源系统中的太阳能和储能以及柴油发电机混合系统。我们还考虑通过电热进行未来能源系统规划。我们发现，在各种经济条件下，太阳能和电池储能有助于降低卡纳克的发电成本。目前，即使考虑到未来资本成本的下降，氢存储也会增加卡纳克的能源成本。然而，绿色氢作为长期能源规划战略可能会对能源产生积极影响。
Many remote Indigenous communities in the high Arctic rely on diesel or other fossil fuels for their electricity generation, yet the high cost of the imported fuel limits households’ ability to afford food and adequate housing and in turn, undercuts living conditions in the Arctic. While roughly 65% of energy generated by the Greenlandic utility company Nukissiorfiit comes from renewable sources, nearly 70% of public and private energy consumption for electricity and heat is fossil-fuel based Naalakkersuisut (2018) [1] . A transition to renewable energy achieved in partnership with the communities could strengthen local energy self-reliance and build technical capacity in ways that embrace their cultural heritage. This paper examines initial feasibility of the incorporation of solar energy for the hunting/fishing village of Qaanaaq, Greenland, a challenging environment where there is little wind or hydropower potential. Unit commitment optimization models are used to assess the feasibility of possible energy projects that include solar energy and energy storage in Qaanaaq’s energy system, in hybrid systems with diesel generators. We also consider future energy system planning via electrified heat. We find that under a variety of economic conditions, solar and battery electric storage contribute to decreased costs to generate electricity in Qaanaaq. Currently, hydrogen storage is found to increase costs of energy in Qaanaaq, even considering future decreases in capital costs. However, green hydrogen may have positive impacts to the energy as a long-term energy planning strategy.
