簡介目錄

據估計，2026年全球熱能儲存市場規模為58億美元，預計到2032年將達到102億美元，2026年至2032年的複合年成長率為9.9%。

熱能儲存正成為轉型為柔軟性、可再生和電氣化能源系統過程中的關鍵要素。這項技術可以將能量以熱能或冷能的形式儲存，並在需要時釋放，從而幫助工業設施、建築、區域供熱網路和發電工程適應能源供需的波動。熱能儲存還可以透過將能源消耗轉移到電費較低的非尖峰時段，來減少對高成本電時段的依賴。

該市場涵蓋顯熱儲能、潛熱儲能和熱化學儲能技術。目前，顯熱儲能系統佔據最大市場佔有率，這主要歸功於水、熔鹽、混凝土、岩石、陶瓷、耐火磚和導熱油等材料的商業性及其相對較低的成本效益。潛熱儲能利用相變材料在熔化和凝固過程中吸收和釋放熱量。熱化學儲能則利用可逆的化學反應或吸附反應，實現更高的能量密度和更低的待機損耗，但其商業性應用仍處於起步階段。

市場的一個重大轉變是熱能儲存技術在工業熱能電氣化中的應用日益廣泛。熱能儲存電池可以將低成本的可再生能源轉化為持續的蒸氣或高溫製程熱。當最終用途是熱能而非電能時，這為化學電池儲能提供了一種替代方案。同時，熔鹽儲能仍在集中式太陽熱能發電中發揮重要作用，而冷凍水和冰儲能則繼續為商業建築、園區、資料中心和區域冷卻提供支援。

市場促進因素

工業熱能的電氣化正在為熱能儲存創造重要的全新應用。即使再生能源生產和價格波動，工業生產過程通常需要持續的蒸氣或高溫熱能。熱能儲存技術使工業用戶能夠在電價低廉時將熱量儲存在系統中，並在整個生產週期中釋放這些儲存的熱量。這使得電力採購與熱能消耗的時間分離，從而有望提高工業電氣化的經濟效益。
工業熱能儲存系統正日益普及，並且已商業化應用。採用耐火磚、陶瓷介質、混凝土、鹽以及其他固體或液態熱能儲存材料的系統，即使在熱能儲存期結束後也能持續加熱。這為需要蒸氣或高溫製程熱的能源密集產業創造了新的機會。
可再生能源發電的減少和電價的波動進一步凸顯了儲熱提案的價值。風能和太陽能發電可能會經歷電價低迷甚至為負值的時期，隨後又會迎來電價高企的時期。儲熱技術可以在電價低迷時期吸收電力，並在之後提供熱能。能夠在不中斷用戶熱負載的情況下調整充電時間，對於工業設施和區域供熱系統而言是一項重要的營運優勢。
熱能儲存還可以用於支援需量反應和電網調節。它能夠在根據電力市場狀況調整充電的同時，維持對終端用戶的供熱。這使得儲能的價值超越了單純的能量轉移。
聚光型太陽熱能發電（CSP）持續推動熔鹽儲熱的需求。熔鹽是目前最成熟的高溫儲熱技術之一。聚光型太陽熱能發電發電廠利用儲熱系統，在陽光直射期結束後仍能持續發電。中國不斷擴大的聚光太陽能發電專案建設週期，對儲存槽、熔鹽堆場、熱交換器、泵浦、蒸氣發生設備及相關控制設備產生了顯著的需求。
太陽熱能發電與8-16小時儲熱結合的大型專案正在拓展熔鹽系統的現有市場。這為熔鹽系統奠定了堅實的商業性基礎，而新型熱電池技術則為其開闢了更多工業應用領域。
建築物和區域供熱系統需要靈活的暖氣和冷氣。冷凍水箱和冰蓄冷系統使商業建築、園區和資料中心能夠將冷凍負載從用電高峰時段轉移出去。同樣，熱水儲存可以為區域供熱網路和熱泵系統提供支援。這些應用具有直接儲存熱能而無需將其轉化為電能的優勢。
新一代相變材料和熱化學材料的開發進一步拓展了建築級緊湊型儲熱的可能性。這些技術能夠實現更高的能量密度，並且適用於空間有限的應用場景。

市場限制因素

熱能儲存的經濟效益受溫度、儲存時長、能源來源、安裝條件、使用者熱負荷等因素影響顯著。採用水或熔鹽的大規模儲能系統需要相當大的物理空間。高溫系統還需要有效的隔熱、耐火材料以及熱膨脹控制。
熔鹽系統在運作和材料方面都面臨挑戰。某些熔鹽在溫度低於其工作範圍時會凍結，因此需要精確的溫度控制和伴熱。高溫下腐蝕也是一個問題。這些要求增加了系統的複雜性，並對材料和運行控制提出了更高的要求。
相變材料存在技術限制。相分離、導熱係數低、循環過程中的性能劣化都會影響其性能。開發人員必須在能量密度、可靠的傳熱性能和長期穩定性之間取得平衡。熱化學系統在材料選擇、反應器設計、可逆反應和循環耐久性方面還面臨更多挑戰。
工業整合可能會增加專案的複雜性。蓄熱系統必須與現有的蒸氣、熱油、熱風或其他製程熱網路連接，且不得中斷生產。因此，系統的價值不僅取決於其蓄熱容量，還取決於其與客戶現有製程的整合效率。
此外，如果目標是“電能到電能的轉換”，那麼儲熱的吸引力可能會降低。這是因為在將電能轉換為熱能以及將儲存的熱能轉換回電能的過程中都會產生損耗。除非需要長期儲熱和保障電網穩定性來支援電能的再轉換，否則直接利用熱能通常能帶來更大的經濟效益。

Thermal energy storage is becoming an important component of the transition toward flexible, renewable, and electrified energy systems. The technology enables energy to be stored as heat or cold and released when required, helping industrial facilities, buildings, district-energy networks, and power-generation projects manage variable energy supply and changing demand. Thermal energy storage can also reduce dependence on high-cost electricity periods by shifting energy consumption toward lower-price hours.

The market includes sensible heat, latent heat, and thermochemical storage technologies. Sensible heat systems currently account for the largest share because water, molten salt, concrete, rocks, ceramics, refractory bricks, and thermal oils are commercially established and relatively cost-effective. Latent storage uses phase-change materials to absorb and release heat during melting and solidification. Thermochemical storage uses reversible chemical or sorption reactions and offers higher energy density and lower standby losses, although commercial deployment remains at an earlier stage.

A major shift in the market is the growing use of thermal storage for industrial heat electrification. Thermal batteries can convert low-cost renewable electricity into continuous steam and high-temperature process heat. This creates an alternative to storing electricity in chemical batteries when the end-use requirement is heat rather than electricity. At the same time, molten-salt storage remains important for concentrated solar power, while chilled-water and ice storage continue to support commercial buildings, campuses, data centers, and district cooling.

Market Drivers

Industrial heat electrification is creating a major new application for thermal energy storage. Industrial processes often require continuous steam or high-temperature heat, even when renewable electricity production and electricity prices fluctuate. Thermal storage allows industrial users to charge a system when electricity is inexpensive and discharge stored heat throughout the production cycle. This separates electricity procurement from the timing of heat consumption and can improve the economics of industrial electrification.
Industrial thermal batteries are increasingly being deployed at meaningful commercial scale. Systems using refractory brick, ceramic media, concrete, salt, and other solid or liquid storage materials can provide continuous heat after the charging period. This creates opportunities across energy-intensive industries that need steam or high-temperature process heat.
Renewable-energy curtailment and electricity-price volatility are strengthening the value proposition. Wind and solar generation can create periods of low or negative electricity prices followed by higher-price periods. Thermal energy storage can absorb electricity during these low-cost periods and deliver heat later. The ability to shift charging without interrupting the customer's thermal load provides an operational advantage for industrial facilities and district-energy systems.
Thermal storage can also support demand response and balancing. Charging can be adjusted according to electricity-market conditions while maintaining heat availability for the end user. This increases the value of storage beyond simple energy shifting.
Concentrated solar power continues to support molten-salt storage demand. Molten salt is one of the most established high-temperature thermal storage technologies. Concentrated solar power plants use thermal storage to extend electricity generation beyond periods of direct solar availability. China's expanding CSP construction cycle is creating significant demand for storage tanks, salt inventory, heat exchangers, pumps, steam-generation equipment, and associated controls.
Large projects combining solar-thermal generation with eight to sixteen hours of storage are expanding the established market for molten-salt systems. This provides a strong commercial base while newer thermal battery technologies develop additional industrial applications.
Buildings and district-energy systems require flexible heating and cooling. Chilled-water tanks and ice storage allow commercial buildings, campuses, and data centers to shift cooling loads away from peak electricity periods. Hot-water storage can similarly support district heating networks and heat-pump systems. These applications benefit from the ability to store thermal energy directly without converting it back into electricity.
The development of next-generation phase-change and thermochemical materials is further expanding the potential for compact building-level storage. Such technologies can provide higher energy density and support applications where available space is limited.

Market Restraints

Thermal energy storage economics vary significantly according to temperature, duration, energy source, site conditions, and the customer's thermal load profile. Large water and molten-salt storage systems require substantial physical space. High-temperature systems also require effective insulation, refractory materials, and thermal-expansion management.
Molten-salt systems face operating and material challenges. Some molten salts can freeze when temperatures fall below their operating range, requiring careful temperature management and heat tracing. Corrosion can also become an issue at elevated temperatures. These requirements increase system complexity and require appropriate materials and operating controls.
Phase-change materials face technical limitations. Phase segregation, limited thermal conductivity, and cycling degradation can affect performance. Developers must balance energy density with reliable heat transfer and long-term stability. Thermochemical systems face additional challenges involving material selection, reactor design, reversible reactions, and cycle durability.
Industrial integration can increase project complexity. Thermal storage systems must be connected to existing steam, thermal-oil, hot-air, or other process-heat networks without interrupting production. The value of a system therefore depends not only on storage capacity but also on how effectively it integrates with the customer's existing process.
Thermal storage can also be less attractive when the objective is electricity-to-electricity conversion. Converting electricity into heat and then converting stored heat back into electricity introduces losses. Direct thermal applications generally provide a stronger economic case unless electricity reconversion is supported by long-duration storage or grid-stability requirements.

Technology and Segment Insights

The market is segmented by storage technology, storage medium, temperature range, application, energy source, and geography.
Sensible heat storage remains the largest technology segment. It accounts for approximately 72% of 2026 market revenue. The segment includes hot and chilled water, ice-assisted systems, molten salts, thermal oils, rocks, concrete, ceramic media, and refractory bricks. Its leading position reflects the commercial maturity of these materials, established engineering practices, relatively low material costs, and extensive field experience.
Latent heat and phase-change storage represents a smaller but established category. Phase-change materials store energy through melting and solidification and can deliver relatively stable discharge temperatures. These characteristics make them useful for building cooling, cold-chain applications, compact thermal storage, and selected industrial processes.
Thermochemical storage is the most advanced technology-development category but remains commercially smaller. Its principal advantage is high energy density combined with low standby heat loss. This makes it attractive for compact and potentially long-duration applications. However, materials and reactor complexity continue to limit broad commercial deployment.
By storage medium, the market includes water and ice, molten salt, concrete and cementitious media, refractory brick and ceramic media, rocks, sand and recycled mineral media, phase-change materials, and thermochemical materials.
Water and ice remain important for building HVAC and district-energy applications. Molten salt dominates established CSP storage. Solid materials such as brick, concrete, ceramics, and recycled minerals are gaining importance in industrial thermal batteries because they can provide high-temperature heat using relatively accessible materials.
By temperature range, the market covers below 50°C, 50-150°C, 150-400°C, 400-700°C, and above 700°C.

A 12 MWh power-to-heat plant with integrated thermal storage was also commissioned in Germany. Kraftblock and Tata Steel reached one year of operation for a 20 MWh high-temperature storage system in Jamshedpur.
Rondo Energy and Covestro also broke ground on a 100 MWh heat battery in Germany, demonstrating the movement toward larger industrial installations. Kyoto Group's 56 MWh molten-salt Heatcube in Hungary provides another example of thermal storage being combined with industrial steam and energy-market participation.
These projects indicate a transition from demonstration-scale installations toward larger commercial systems. As customers gain operational experience, suppliers are expected to focus increasingly on standardized designs, financing models, heat-as-a-service structures, and integration with renewable electricity.
