Resumo:
Integrating intermittent renewable sources with energy storage systems is an effective strategy to enhance energy network reliability and ensure power availability. This study examines three different energy storage technologies: Compressed Air Energy Storage (CAES), hydrogen, and lithium-ion batteries. These systems are coupled with photovoltaic panels and applied to a residential building in Lyon (France) and Rio de Janeiro (Brazil). The analysis spans a full year of operation and is evaluated using a 4E approach, assessing energy, exergy, exergoeconomics, and environmental impact. In terms of efficiency, CAES and hydrogen systems exhibit similar performance, except in the trigeneration configuration, where hydrogen demonstrates superior results. From an economic standpoint in both Rio de Janeiro and Lyon, when compared to business as usual, the hydrogen system incurs the highest costs (+260.9% and +244.1%), followed by CAES (+206.4% and +197.8%) and the lithium-ion batteries (+71.0% and +67.6%). Regarding environmental impact, CAES and lithium-ion batteries effectively reduce CO2 equivalent emissions in both cities, with greater benefits observed in Rio de Janeiro. In contrast, the hydrogen system only becomes viable when biogas replaces natural gas, as the system's performance improves significantly, substantially reducing the cost of avoided CO₂ emissions. With this configuration, all systems are able to avoid emission, notably in Rio de Janeiro, with 24.3 tons, 50.0 tons, and 26.1 tons for CAES, hydrogen and lithium-ion batteries. In Lyon, the values are lower with 2.45 tons, 15.3 tons and 1.49 tons. Overall, all three systems show promising potential, but their feasibility depends on cost reductions and efficiency improvements of its components.
