Abstract
<title>Abstract</title> <p>As artificial intelligence advances, the demand for data centers has increased substantially, making their considerable energy consumption a significant challenge. In Japan, difficulties in securing land and power supplies in major metropolitan areas has prompted a shift in data center construction toward regional cities. However, in regions with insufficient power infrastructure, distributed power sources become essential. This study focuses on woody biomass, which, despite its stable supply capability, presents the limitation of low conversion efficiency. Therefore, this study uses combined cooling, heat, and power (CCHP) systems, improving efficiency by simultaneously supplying electricity and cooling. The primary objective of this study is to perform a comprehensive performance analysis focusing on the environmental impact and operational effectiveness of the proposed biomass-integrated CCHP system. Specifically, we conducted an energy utilization efficiency assessment, a business viability assessment based on data center operations, and an environmental impact assessment using life cycle analysis. Analysis results indicate that this system achieves approximately 7.3 percentage points higher efficiency than conventional systems. Regarding business viability, the system was found to generate approximately 1.89 times the profit over a five-year period compared to electricity sales alone. Furthermore, it was demonstrated that the proposed system reduces global warming potential by 82.3%. In conclusion, biomass-integrated CCHP and power systems represent an effective approach for achieving high efficiency, strong business viability, and low environmental impact, serving as a stable power supply solution for data centers in regional cities.</p>
