Renewable Energy Optimization Strengthened by Linwei Wu’s Analytical Contributions to Hybrid Geothermal-Biomass Systems

A hybrid geothermal–biomass system integrates multigeneration heating, cooling, and power through thermodynamic and economic optimization. Using exergy analysis and particle swarm optimization, the study reveals performance trade-offs, identifies key efficiency losses, and demonstrates how biomass integration can enhance renewable energy flexibility and system-level decision making.

New York, NY, United States, December 22, 2025 — Traditional geothermal systems face persistent challenges, including low output temperatures and strict location dependence, limiting broader renewable-energy deployment. The research addresses these constraints by proposing a biomass-boosted geothermal configuration that integrates double-effect and single-effect absorption refrigeration cycles with water-heating functions. Through biomass combustion supplementing geothermal heat, the hybrid system enables combined electricity, cooling, and heating generation, expanding functional capabilities beyond those of conventional geothermal plants.

To evaluate system performance, the study develops comprehensive thermodynamic and economic models supported by exergy analysis and multi-objective optimization. The framework incorporates Particle Swarm Optimization algorithms to compare outcomes under varying operational parameters. Modeling results show that increasing the superheated geofluid temperature from 250°C to 350°C reduces fixed capital investment from $5.19 million to $4.51 million but simultaneously lowers net present value from $5.5 million to $3.268 million, illustrating critical trade-offs between cost and long-term economic output.

Under optimized operating conditions, the system achieves a net power output of 759.4 kW, a cooling load of 10,111 kW, and a heating output of 2,870 kW. Component-level exergy assessments identify the combustion chamber, desorber units, and air preheater as major sources of exergy destruction, with the geothermal subsystem responsible for 58.53 percent of total losses. These results indicate that the combustion chamber, desorber units, and air preheater account for the highest exergy destruction, while the geothermal power subsystem contributes 58.53 percent of the total.

These experiences underscore capabilities in data preparation, modeling, and cross-functional analytical support across operational and research contexts.

Through thermodynamic, exergy, and techno-economic analyses supported by multi-objective optimization, the study provides a detailed assessment of the geothermal–biomass multigeneration system’s performance. The results show how changes in operating conditions shape net power output, cooling and heating capacity, exergy efficiency, and economic indicators such as fixed capital investment and net present value. This analytical framework clarifies the system’s operational behavior and supports informed configuration decisions within hybrid renewable-energy designs.
