South Korea has increasingly expanded the adoption of renewable energy, especially solar power. Smart farms are one example of renewable energy applications but require both electricity and heat demand. Previous studies have shown that the target smart farm does not achieve 100% energy self-sufficiency rate under current conditions. Therefore, renewable energy-based autonomous energy systems and their operational strategy are required to reduce grid dependency with full energy autonomy. This study proposes a scenario-based energy autonomy framework that integrates life-cycle assessment and techno-economic analysis for smart farms with coupled electricity and heat demands using measured operational data. Analysis results indicated that the proposed energy autonomous scenario could reduce CO<sub>2</sub> emissions by up to approximately 92% compared to a centralized grid-based system. It also improved economic viability, lowering the LCOE from $0.435 to $0.287/kWh compared with the existing operating model. Sensitivity analysis identified electricity and wood pellet prices as the most influential economic factors. Consequently, a 60% solar-40% biomass configuration provides the optimal balance between environmental performance and economic efficiency.

The two-step solar thermochemical technology provides a promising path for sustainable fuel production from H<sub>2</sub>O and CO<sub>2</sub> with concentrated solar energy. However, current solar-to-fuel efficiency is still far from commercial requirements, due to two main limiting factors: (1) severe sensible heat loss due to temperature swings between reduction and oxidation steps; (2) discontinuous utilization of solar energy during solar periods caused by alternating two-step reactions. To address this issue, a novel solar thermochemical system consisting of dual solar reactors combined with heat exchange devices is proposed in this study. This design not only enables simultaneous reduction and oxidation during solar periods for uninterrupted fuel production, but also, through the application of heat exchange devices, facilitates effective recovery of sensible heat between reduction and oxidation phases and from waste high-temperature gases and solid metal oxides, thereby reducing heat losses. Results show solar-to-fuel efficiency increases by 112%–389% compared to conventional systems, and can reach 26.07% at the reduction temperature of 1993 K.
