Novel Nitrogen Hybrid Gas-Based Nanofoam System for Enhanced Geothermal Applications: Nanogeios and GEIOS Geothermal EQG Laboratory Validation Study

This paper presents comprehensive laboratory validation results for an innovative nitrogen hybrid gas nanofoam system engineered specifically for enhanced geothermal applications. The system, comprising a nitrogen gas matrix (95% by volume) with precisely engineered aluminum oxide (0.6-0.8% vol) and silica (0.3-0.5% vol) nanoparticles, demonstrates unprecedented improvements in both fracture stability and thermal conductivity under simulated geothermal conditions. Laboratory testing conducted between March and November 2024 at pressures between 80-140 MPa and temperatures up to 240°C revealed sustained fracture apertures of 3 mm with only 12% degradation over 15 weeks of continuous operation. Thermal conductivity measurements demonstrated consistent values of approximately 30 W/m·K, representing a 166-336% enhancement over conventional materials. The system maintained exceptional stability with Reynolds numbers exceeding 10⁴ and Weber numbers above 50, while achieving uniform particle distribution (CV <15%) and minimal coalescence rates (<0.1% per hour). These results validate the technology's potential for commercial-scale geothermal power generation, particularly for the planned 200 MW project implementation.

This paper presents laboratory validation results for an innovative gas-based nanofoam system engineered for enhanced geothermal applications. The study, conducted in 2024, demonstrates significant improvements in fracture stability and thermal conductivity through the integration of engineered nanoparticles within an inert gas matrix. Testing under simulated geothermal conditions showed sustained fracture stability with minimal degradation over extended testing periods, while achieving substantial thermal conductivity enhancements compared to conventional systems.
