“…Although it is important to examine the impacts of individual factors on community energy initiatives, community energy also needs to be explored from a more comprehensive context because its success is context-dependent. Recently, Sperling [19] took a more structured approach to exploring the internal and external contextual conditions that enabled success in Samsø, Denmark. Since communities are "embedded in and constituted by dynamics between socio-cultural, biophysical, economic, political, and legal subsystems", [31] (p. 5117) community initiatives can be promoted or discouraged by those conditions [25,30].…”

“…The structural context that enables these community activities has not yet been investigated, however. Sperling [19] argued for understanding the context of community energy initiatives: "these contextual factors and their interrelations should be understood in detail, if we want to make sense of the specific reasons for why community energy projects succeed or fail, as well as for decision makers and local practitioners to be able to design adequate policies and processes that can promote the former and prevent the latter" (p. 885).…”

While community energy initiatives are on the rise, community actions for energy transition in Asian countries have rarely been studied. While it is difficult for community energy initiatives to develop spontaneously in Seoul, there are some success stories there. This study places these successes in context. It analyzes municipal documents, including unpublished materials from municipal meetings, in order to examine how the Seoul Metropolitan Government (SMG) created enabling conditions for promoting community energy initiatives. This study also conducted interviews to explore unsolved issues related to the Energy Self-Reliant Village (ESV) program. The SMG encouraged collective action through financial, administrative, and informational support. Also, this study found that Seoul's ESV program fostered communities by raising the sense of locality and responsibility and community spirit through various educational programs. The ESV program supported the continuity of community by providing guidelines that relieved the burden on community members. The SMG played a significant role in promoting community engagement in energy transition by affecting internal and external conditions. This study provides meaningful insights that other municipalities, especially large urban areas, can follow to foster community actions for energy transition.

“…Moreover, on one of the resulting charts from [8], it could be seen that all the future scenarios modelled for the Åland Islands had between 2% and 28% of the energy curtailed, a much larger amount than in the present paper. Furthermore, this case study generated 78.1% of electricity from the variable energy sources, compared to the 38% for the case of renewable energy on Samsø island [16] and around 50% for the case of renewable energy on Reunion island [15]. In addition, the local integrated energy system without the import/export transmission capacity achieved a 57% share of the variable renewable energy generation, without the reported curtailed energy (modelled on a 1 h temporal resolution) [45].…”

“…However, the authors focused solely on the power sector and not on the whole energy system. Finally, Samsø island in Denmark achieved a 100% net renewable electricity supply by a set of different energy policies and a significant inclusion of the local population in the transition [16]. Their technical solution included around 38% of primary energy demand met by variable renewable energy sources, mostly by wind, while other sources in the power sector included biomass and straw [16].…”

Integrated Energy Planning with a High Share of Variable Renewable Energy Sources for a Caribbean Island

et al. 2018

Abstract:Although it can be complex to integrate variable renewable energy sources such as wind power and photovoltaics into an energy system, the potential benefits are large, as it can help reduce fuel imports, balance the trade, and mitigate the negative impacts in terms of climate change. In order to try to integrate a very large share of variable renewable energy sources into the energy system, an integrated energy planning approach was used, including ice storage in the cooling sector, a smart charging option in the transport sector, and an excess capacity of reverse osmosis technology that was utilised in order to provide flexibility to the energy system. A unit commitment and economic dispatch tool (PLEXOS) was used, and the model was run with both 5 min and 1 h time resolutions. The case study was carried out for a typical Caribbean island nation, based on data derived from measured data from Aruba. The results showed that 78.1% of the final electricity demand in 2020 was met by variable renewable energy sources, having 1.0% of curtailed energy in the energy system. The total economic cost of the modelled energy system was similar to the current energy system, dominated by the fossil fuel imports. The results are relevant for many populated islands and island nations.

Energy, exergy, and sensitivity analyses of underwater compressed air energy storage in an island energy system

et al. 2019

View full text Add to dashboard Cite

Summary An underwater compressed air energy storage (UWCAES) system is integrated into an island energy system. Both energy and exergy analyses are conducted to scrutinize the performance of the UWCAES system. The analyses reveal that a round‐trip efficiency of 58.9% can be achieved. However, these two analyses identify different directions for further improvement. The heat exchangers, expanders, compressors, electric motors, and generators account for the most exergy destruction. A sensitivity analysis is also conducted to investigate the importance of different input parameters on the round‐trip exergy efficiency of the UWCAES system. The results of both local and global analyses show that the round‐trip exergy efficiency is most sensitive to the isentropic efficiency of the expanders and compressors, and the efficiencies of the electric motors and generators. The impacts of the heat exchangers, the self‐discharge rate of the air accumulator, the inner diameter of the pneumatic pipelines, and the insulation thickness of the hot‐oil tank on the round‐trip exergy efficiency are shown to be highly nonlinear.
