Renewables in Antarctica: an assessment of progress to decarbonize the energy matrix of research facilities

Abstract

Abstract This paper tracks the progress of renewable energy deployment at Antarctic facilities, introducing an interactive database and map specifically created for this purpose. Goals, challenges and lessons learnt from these operations are also reported. The data and assessments presented are based on a literature review of government reports, academic articles, online resources, news outlets and interviews conducted with personnel of Antarctic stations. As of 2021, 29 facilities have incorporated renewables in their energy systems, but only one permanent and four summer stations use renewables to meet more than 50% of their energy needs. Four main goals behind the development of renewable energy systems have been identified: fuel cost savings; reduction of the greenhouse gas emissions footprint in alignment with national decarbonization targets; electricity supply for scientific equipment during the winter months; and the development and/or testing of new technologies. The extreme weather conditions and complex logistics of Antarctica put both solar and wind systems under huge stress, which generates operational, technological and budgetary challenges that are also explored in this work.
