日本語
本レビューは2018〜2025年の100以上の研究を統合し、集光型太陽熱発電（CSP）の進展を評価。ナノ流体や相変化材料による熱貯蔵の効率向上、PV・地熱・水素等とのハイブリッド化でCO2排出を最大90%削減可能と示す。ライフサイクル評価では排出量が50g CO2/kWh未満、2050年には18gまで低下見込み。一方、実証不足や環境影響、社会的受容性が課題。
English
This review synthesizes over 100 studies (2018-2025) on Concentrated Solar Power (CSP), highlighting advances in thermal storage via nanofluids and phase-change materials, and hybrid systems with PV, geothermal, biomass, and hydrogen that can cut CO2 emissions by up to 90%. Life-cycle assessments report GHG emissions below 50 g CO2/kWh, potentially approaching 18 g by 2050. Challenges remain in scale-up, environmental impacts, and social acceptance.

📄 Abstract（原文）
Concentrated Solar Power (CSP) technologies are increasingly seen as vital for decarbonizing high-temperature industrial processes and providing dispatchable renewable electricity. This review consolidates findings from more than 100 peer-reviewed studies (2018–2025), focusing on recent progress in CSP, particularly in thermal energy storage (TES), nanomaterial-enhanced heat transfer fluids, hybrid systems with other energy sources, and socio-environmental impacts. It shows that nanofluids containing Ti₃C₂ and CuO can boost thermal conductivity by up to 85%, while nanoencapsulated phase change materials (PCMs) improve energy density and cyclic stability. Current research hotspots are oxide- and MXene-based nanofluids, whereas in-situ molten-salt nanofluids and nanoencapsulated PCMs exhibit stronger breakthrough potential but still face scale-up, stability, corrosion, and toxicity constraints. Hybrid CSP systems integrating photovoltaics, geothermal energy, biomass, desalination, and hydrogen production demonstrate higher exergy efficiencies, water-energy synergies, and CO₂ emission reductions of up to 90%; however, much of the evidence base remains dominated by modeling rather than long-duration demonstration under practical operating conditions. Life Cycle Assessments report greenhouse-gas emissions below 50 g CO₂/kWh, with projections to approach 18 g CO₂/kWh by 2050. Social benefits include job creation, decentralized electrification, and support for energy sovereignty in off-grid and remote communities. Nonetheless, challenges remain regarding biodiversity impacts, water consumption, land use, nanomaterial and molten-salt pollution risks, and culturally sensitive deployment. Overall, CSP’s future depends on modular, hybrid, multi-generation systems designed with local stakeholders, supported by robust policy frameworks and environmental safeguards, and evaluated through scenario-based metrics that capture dispatchability rather than static daytime cost alone.
