Molten Salt Thermal Energy Storage Market - Forecasts from 2025 to 2030

The Molten Salt Thermal Energy Storage Market is anticipated to climb from USD 1.554 billion in 2025 to USD 3.128 billion by 2030, with a 15.02% CAGR.

The global molten salt thermal energy storage (TES) market is poised for substantial growth during the forecast period, driven by escalating energy consumption due to population expansion, supportive government policies promoting renewables, and declining costs per kilowatt for energy storage. Molten salt TES, primarily utilized in concentrating solar power (CSP) systems, offers a reliable method for storing thermal energy, enabling electricity generation during non-sunlight hours. This technology provides a distinct advantage over photovoltaic systems by facilitating dispatchable power, enhancing grid stability and renewable integration. However, competition from alternatives like battery and pumped hydro storage presents notable restraints.

Market Drivers

A key driver is the integration of molten salt TES in CSP technologies, including central receiver direct-storage and parabolic trough indirect-storage plants. These systems capture solar radiation and store it thermally, supporting continuous power output. Innovations such as self-aligning heliostat technology, developed by research teams in the US and Europe, are enhancing CSP performance while reducing costs. In China, advancements like AI-integrated systems mitigate cloud-related risks at high altitudes, improving operational efficiency. The environmental benefits of molten salt, which is approximately 33 times cheaper than lithium-ion batteries, align with global sustainability goals. For instance, Sweden's commitment to phasing out fossil fuels for electricity generation by 2040 underscores the rising demand for low-carbon storage solutions. Increased R&D investments are further propelling market expansion by optimizing TES for scalability and cost-effectiveness.

Market Segmentation

The molten salt TES market is segmented by technology (direct and indirect storage), application (CSP plants, industrial processes, and others), and geography (North America, South America, Europe, Middle East and Africa, Asia-Pacific). CSP applications dominate, with indirect TES parabolic trough plants prevalent in utility-scale deployments, offering extended storage durations of over seven hours at full capacity.

Geographical Outlook

The Asia-Pacific region is expected to lead market growth, with China and India as primary contributors. China's substantial investments in renewables have positioned it as a major adopter of molten salt TES, leveraging its vast solar resources for large-scale CSP integration. India is advancing its clean energy agenda through ambitious renewable targets, fostering demand for efficient storage to balance intermittent solar output. Other regions, including North America and Europe, are witnessing steady adoption, supported by technological innovations and environmental regulations.

Challenges

The market faces restraints from competitive substitutes, including battery storage and pumped hydro systems, which offer flexibility and rapid deployment in certain applications. These alternatives may limit molten salt TES penetration in scenarios requiring quick response times or decentralized setups, necessitating strategic differentiation through cost and performance advantages.

Competitive Landscape

Major players such as Torresol Energy Group, BrightSource Energy, Inc., Acciona AS, Abengoa SA, Yara International ASA, ENGIE Group, ACWA Power, Lanco Group, and KVK Energy Ventures Ltd. are intensifying competition through joint ventures, mergers, and acquisitions to expand global footprints. These strategies enable access to emerging markets and collaborative R&D for next-generation TES solutions.

The molten salt TES market is set for accelerated growth, propelled by renewable energy mandates, cost reductions, and technological advancements in CSP integration. Asia-Pacific's dominance, led by China and India, highlights regional opportunities, while innovations address efficiency challenges. Overcoming competition from alternative storage technologies will be crucial for stakeholders to capitalize on the shift toward sustainable, dispatchable solar power.
