Hybrid Plasma-Based Energy Generation System: A Disruptive Approach to Sustainable Power and Hydrogen Production

Abstract The transition to sustainable and high-efficiency energy systems is imperative in addressing the global energy crisis, climate change, and geopolitical uncertainties. This paper presents a novel hybrid plasma-based energy generation system, designed to surpass the limitations of conventional nuclear and renewable energy technologies by integrating: 1. High-efficiency plasma-to-electricity conversion: Leveraging advanced plasma discharge mechanisms to achieve efficiencies exceeding 85%. 2. Residual thermal energy utilization for hydrogen production: Employing thermochemical processes to significantly reduce the energy intensity of hydrogen generation. 3. Large-scale energy storage through hydroelectric reservoir integration: Enhancing grid stability and mitigating intermittency challenges inherent to renewables. Computational simulations, thermodynamic modeling, and techno-economic analyses reveal that the proposed system achieves an energy density 15.6 times higher than conventional nuclear power plants, while operating with zero carbon emissions. Additionally, the integration of hydroelectric storage solutions optimizes energy dispatchability, reducing reliance on grid-based storage and fossil-fuel peaker plants. Economic feasibility assessments indicate that the system enables a rapid return on investment (ROI) of approximately 1.5 years, compared to the 10+ years typically required for nuclear infrastructure amortization. The lower capital cost per installed megawatt, coupled with modular scalability, positions this technology as a competitive alternative for large-scale power generation, particularly in industrial applications and national energy grids. The results underscore the disruptive potential of this technology in energy security, decarbonization, and long-term sustainability. This hybrid plasma system presents a viable pathway toward continuous, high-density, and cost-effective power generation, aligning with global energy transition strategies and the urgent need for carbon-neutral industrial solutions.
