小型模組化反應器 (SMR) 市場成長驅動因素

隨著對清潔、可靠和靈活的能源解決方案的需求不斷增長，全球小型模組化反應器 (SMR) 市場正穩步發展。預計該市場規模在 2025 年將達到 59.6 億美元，2026 年將成長至 61.3 億美元，到 2034 年將達到 87.7 億美元，預測期內複合年增長率 (CAGR) 為 4.59%。 SMR 是一種緊湊型核反應堆，在工廠設計和製造，然後運輸到運作現場，為商業、工業和建築應用提供電力。 SMR 的最大輸出功率為 300 兆瓦 (MWe)，具有高可靠性、高效率和高適應性，使其非常適合現代能源需求。通用電氣是領先的先進模組化反應器解決方案供應商之一，其產品融合了最新的核子技術。

市場動態

驅動因素：

全球對清潔能源日益增長的興趣是小型模組化反應器 (SMR) 市場的主要驅動因素。各國政府越來越重視再生能源和低碳能源，這使得核能成為極具吸引力的解決方案。 SMR 能夠在提供可靠電力的同時，最大限度地減少對環境的影響。此外，工業領域的電力消耗成長也推動了公用事業、資料中心和製造工廠採用 SMR 進行發電。

限制因素：

一個關鍵挑戰是缺乏標準化的 SMR 部署許可和監管框架。設計審批、製造認證和部署成本方面的各種要求正在影響市場成長，營運商在各國都面臨監管審批的延誤。

機會：

全球對資料中心的需求不斷增長，為 SMR 帶來了巨大的機會。隨著人工智慧、雲端運算和高效能工業營運等因素導致電力消耗不斷成長，企業正在考慮採用小型模組化反應器（SMR）技術來高效穩定能源供應。根據國際能源總署（IEA）預測，資料中心預計將在2022年佔全球電力消耗的2%以上，到2026年這一比例將翻倍。

挑戰：

高昂的初始資本成本仍是主要障礙。技術進步、材料成本、勞動成本和通貨膨脹導致一些SMR項目的建設成本波動超過100%。例如，全球目前營運的四座SMR分別位於俄羅斯、中國和日本，其成本遠高於最初的預算。

市場趨勢：

由於其靈活性、低碳排放和可靠性，SMR技術在俄羅斯、中國和阿根廷等國家越來越受到關注。工業和科技公司正擴大採用SMR來確保安全、持續的能源供應。多模組小型模組化反應器 (SMR) 具有可擴展性和運行靈活性，可透過與再生能源整合，實現電網穩定。

新冠疫情的影響

由於工業停工、供應鏈中斷和勞動力短缺，新冠疫情阻礙了 SMR 市場的成長。製造延遲和部件運輸限制暫時阻礙了專案執行。然而，疫情後的復甦和對清潔能源解決方案的重新投資正在再次振興市場。

Growth Factors of small modular reactor (SMR) Market

The global small modular reactor (SMR) market is steadily gaining traction as the demand for clean, reliable, and flexible energy solutions rises. The market was valued at USD 5.96 billion in 2025, projected to grow to USD 6.13 billion in 2026, and expected to reach USD 8.77 billion by 2034, exhibiting a CAGR of 4.59% during the forecast period. SMRs are compact nuclear reactors, designed and manufactured in workshops, then transported to operational sites to provide electricity for commercial, industrial, and building applications. With outputs up to 300 Megawatt electric (MWe), SMRs offer high reliability, efficiency, and adaptability, making them suitable for modern energy demands. General Electric Company is among the key players providing advanced modular reactor solutions integrated with latest nuclear technology.
