Sustainable Energy Integration in Geothermal Exploration: Conceptual Design and Innovation

Geothermal drilling operations in remote areas are commonly powered by diesel generators, leading to high fuel consumption and substantial carbon emissions. This study explores the integration of a hybrid solar PV–diesel generator system to enhance energy sustainability at a geothermal drilling base camp in Indonesia. The system design considers local renewable energy potential and incorporates integration with existing equipment. The integration strategy is evaluated through a feasibility analysis considering system efficiency, energy yield, and environmental impact. Using Helioscope software for solar simulation and load analysis based on equipment specifications, the results show that the PV system can supply up to 35% of the daytime energy demand, reducing daily carbon emissions by 8% and enhancing generator performance through optimized load sharing. Despite the absence of battery storage, the system demonstrates significant environmental and operational benefits, while also highlighting the potential for further improvements through energy storage integration, smart control systems, and targeted energy management.
