再エネ主力電源化に必要な蓄電ポートフォリオを、電気・機械・電気化学・熱・化学の各方式横断で体系的にレビュー。572件の引用リザーバーと549件の文献コーパス、100件の手法検証済み文献を基盤とする。応答時間・放電持続時間・サイクル負荷・立地・気候・系統制約・収益設計により適性が決まり、万能な方式は存在しないと結論。劣化・安全性・デジタル制御・循環性・銀行可能性をライフサイクルで統合し、Storage-to-System Evidence Matrixを提案する。
English
This review synthesizes electrical, mechanical, electrochemical, thermal, and chemical storage for renewable-dominant grids using a transparent evidence architecture (572-record citation reservoir, 549-study bibliometric corpus, 100 method-verified references). It finds no universal storage option dominates; suitability depends on response time, discharge duration, cycling duty, siting, climate, grid constraints, and revenue design. Degradation, safety, digital control, circularity, and bankability are treated as coupled lifecycle considerations, and a Storage-to-System Evidence Matrix is proposed to link duration, services, risk, and finance.

📄 Abstract（原文）
Renewable-dominant power systems require storage portfolios that deliver flexibility, adequacy, resilience, affordability, safety, and responsible resource use across timescales. This review synthesises electrical, mechanical, electrochemical, thermal, and chemical storage using a transparent evidence architecture comprising a 572-record citation reservoir, a 549-study bibliometric corpus, and 100 method-verified references for critical analysis. Technology suitability is shown to depend on response time, discharge duration, cycling duty, location, climate exposure, grid constraints, and revenue design; consequently, no universal option dominates. Batteries and power devices support rapid regulation and daily balancing, whereas pumped hydro, compressed-air, thermal, flow-battery, hydrogen, and hybrid systems address longer scarcity periods with distinct efficiency, siting, safety, and cost trade-offs. The synthesis treats degradation, operational safety, digital control, circularity, and bankability as coupled lifecycle considerations rather than isolated topics. It proposes a Storage-to-System Evidence Matrix linking duration, eligible services, risk, degradation, digital readiness, circularity, resilience, maturity, and finance. Priority actions include duration-aware valuation, representative demonstrations, harmonised safety standards, degradation-linked warranties, interoperable digital architectures, and closed-loop supply chains. Storage planning should therefore optimise service-matched portfolios against verified system needs and lifecycle constraints, strengthening reliable and equitable net-zero electricity transitions.
