Application of renewable and hydrogen energy in the Arctic by the example of modernizing the energy system of the Arctic settlement of Khatanga

Abstract

The primary objective of this article is to assess the use of modern technologies for energy supply to facilities located in the Arctic zone. The focus is on carbon-free energy technologies, including energy storage systems based on the hydrogen cycle. Hydrogen storage systems make it possible to implement long-term cycles of seasonal energy storage from renewable sources, the seasonality of which is more pronounced in the Arctic regions.At the moment, there is a sufficient number of works devoted to the use of various carbon-free technologies in the Arctic, but all of them are devoted to work on the energy supply of narrow-profile facilities, as a rule, Arctic stations. Therefore, the authors of this article decided to consider the use of the hydrogen cycle to ensure a functioning Arctic settlement of Khatanga, with a population of about 5 thousand people. This paper will provide an economic assessment of the project to modernize the energy system with the introduction of renewable sources, as well as hydrogen storage. Together with the assessment, an analysis is provided of the sensitivity of the economic indicators of the project's effectiveness depending on various conditions associated with the location of the system in the Arctic region.
