This research aims to evaluate the economic feasibility of hydrogen transportation in Greenland, focusing on compressed gas via pipelines and liquefied hydrogen via maritime routes. The study employs a comprehensive methodology that includes economic analysis of production, liquefaction, and transportation costs. This approach integrates a wide range of methods available in the literature and considers various components of the hydrogen supply chain, going beyond the typical focus on transportation strategies alone. Results indicate that pipelines are more cost-effective for shorter distances (<1,500 km) and higher demand, whereas shipping is better suited for longer distances and larger volumes. A case study of transporting hydrogen from Paamuit to Nuuk revealed that for a production capacity of 40 t/d, the cost of pipeline transport was 1.3 USD/kg, whereas for shipping it was 2.7 USD/kg. These findings contribute significantly to the development of a hydrogen economy and highlight Greenland's potential as a competitive player in the global green hydrogen market. The research provides valuable insights for decision-makers in planning efficient and economical hydrogen transportation strategies. Læs mere

Various benefits are anticipated in relation to implementation of renewables in Arctic communities, a fact that is driving interest in an appraisal of the state of energy production in the Arctic toward a transition from fossil fuel generated electricity and heating, to an Arctic energy system based on renewable energy sources. To understand and promote the potential for increased implementation of renewable energy solutions, it is important to investigate the role of key factors such as the economy, infrastructure and technology for the transition process. This article is based on an explorative study and analysis of how these three key factors are driving and challenging implementation of renewables. It aims at contributing to the debate on how to promote renewables in the four Arctic areas: Alaska, Canadian Arctic, Greenland and Russian Arctic. Key findings are discussed and recommendations to tackle some of the identified challenges are provided. Læs mere
