Abstract
This study explores the technical feasibility of an integrated system, utilizing a low-temperature proton exchange membrane fuel cell (PEMFC) powered by hydrogen derived from steam reforming of ethanol. The aim is to address the energy needs of isolated Amazonian communities, traditionally reliant on diesel generators, which pose environmental and health hazards. As photovoltaic systems gain popularity, their environmental impact, particularly with batteries, has raised concerns. To mitigate these challenges and achieve energy autonomy, a fuel cell and battery-based system is investigated. To optimize the overall system performance and economic conditions, the best parameters for designing and operating the system were determined by analyzing different scenarios using a developed numerical simulator for hybrid generation systems. This energy storage system could supply nine equivalent SIGFI45 users with 15 kWh (C100) or two SIGFI45 battery banks. A better solution is using this energy storage system with photovoltaic system excluding the custom monitoring, management, and control subsystem (SMGC) using a charge controller like any conventional PV off-grid system. In this case, the battery charge controller prevents overcharging the batteries. This integrated system serves as an advanced energy storage solution, promoting renewable energy adoption in remote regions of Brazil.
