Abstract
Integrated local multi-energy systems are recognized as a promising bottom-up alternative to achieve the ambitious energy and climate goals set by the European Commission for 2030. The nature of integrated multi-energy systems presumes a very complex interaction of different aspects from various energy sectors, which historically functioned more or less independently. Therefore, configuration and development of an integrated local energy system under the energy community concept is an extremely demanding task, requiring a sound interdisciplinary knowledge base. The present study shares results from an activity in H2020 project eNeuron aiming to cover this gap, by introducing the Integrated Local Energy Community definition and providing a deep-dive review of multiple factors influencing the future development of these emerging systems, reviewing the three levels: political priorities, technical overview and limitations plus barriers.
