The Clean energy for EU islands secretariat has published two new technical assistance reports offering insights into emerging clean energy technologies for the Aran Islands, Ireland. The publications provide examples of how islands can harness advanced solutions to support their transition towards renewable, low-carbon energy systems.
The first report, Aran Islands – Battery Energy Storage Overview, outlines the role of battery energy storage systems (BESS) in promoting energy flexibility and grid stability. It describes the key components of battery storage solutions – including battery modules, power conversion systems and energy management systems – and discusses how such systems can capture surplus renewable electricity for use when generation is low. As renewable penetration grows, this kind of storage is seen as a vital tool for reducing reliance on fossil fuels and improving local energy resilience. The report also summarises cost considerations and offers real-world examples to help island authorities assess the feasibility of battery systems in their energy planning.
In parallel, the second publication, Aran Islands – Airborne Wind Technology Overview, explores an innovative class of renewable energy technology: Airborne Wind Energy Systems (AWES). These systems use tethered aircraft operating at high altitudes to access stronger and more consistent wind resources than traditional wind turbines can reach. By converting high-altitude wind into electricity via ground-based generation systems, AWES can offer improved spatial flexibility and potentially lower material costs. The report explains different system configurations, operational principles, cost forecasts, and the advantages and limitations of airborne wind approaches, positioning them as a potential complement to conventional wind power in island settings.
Both reports form part of the secretariat’s ongoing technical assistance to EU islands, underlining its commitment to providing practical, evidence-based resources to support clean energy transitions.
The secretariat, established by the European Commission, works to help island communities overcome energy sector challenges through expert advice and capacity building, contributing to broader EU goals on clean energy and carbon neutrality.
