Molten salt tower CSP market seen reaching $3.39 billion by 2030

The Business Research Company says the molten salt tower concentrating solar power market is growing as utilities and governments look for dispatchable renewable electricity. The market is projected to rise from $1.96 billion in 2025 to $3.39 billion by 2030, driven by renewable adoption, solar capacity expansion and thermal storage demand.

Why it matters: - Molten salt tower CSP is one of the few solar technologies that can store heat and deliver electricity after sunset. - That makes the technology more relevant as power systems look for 24/7 renewable generation and grid stability. - The market’s expected growth signals rising interest in dispatchable clean power, not just daytime solar output.

What happened: - The Business Research Company published a new market report on molten salt tower concentrating solar power. - The report says the market will grow from $1.96 billion in 2025 to $2.19 billion in 2026. - The report projects the market will reach $3.39 billion by 2030. - The forecast implies an 11.3% CAGR from 2025 to 2026 and 11.5% CAGR from 2026 to 2030. - Asia-Pacific held the largest market share in 2025. - North America is projected to be the fastest-growing region during the forecast period. - The report covers Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, and the Middle East and Africa. - More information is available in the company’s sample request page and the full market report.

The details: - Molten salt tower CSP uses heliostats, or mirrors, to focus sunlight on a receiver at the top of a tower. - The receiver heats molten salt, which is then used to produce steam and generate electricity. - The system’s thermal storage lets it keep producing power when sunlight is unavailable. - The report cites government incentives, fossil fuel diversification, early pilot plants, advances in heat transfer fluids, and rising industrial electricity demand as recent growth drivers. - The report says future growth will be supported by utility-scale renewable targets, lower storage costs, hybrid renewable grids, demand for reliable renewable power, and investment in carbon-neutral energy infrastructure. - The report highlights technology trends including improved thermal storage, better heliostat field design, corrosion-resistant receiver materials, hybrid CSP-storage systems, and larger dispatchable utility projects. - The report includes market attractiveness scoring, TAM analysis, company scoring matrices, Excel forecasting dashboards, hotspots infographics, and updated graphics and tables.

Between the lines: - The market story is shifting from solar generation alone to solar plus storage, which is what makes the technology useful for baseload-style renewable power. - The strongest demand signals come from policy support and grid needs, not from cost competition with conventional solar panels. - Regional leadership in Asia-Pacific suggests the technology is still concentrated in markets willing to back large infrastructure projects. - North America’s growth outlook points to broader interest in firm clean energy, even if the technology remains niche.

What's next: - The market will likely track utility procurement, storage economics, and policy support for long-duration renewable power. - Continued investment in hybrid systems and thermal storage could determine whether molten salt tower CSP scales beyond pilot and demonstration projects. - The report frames 2030 as the key checkpoint for whether dispatchable solar can move from a specialized solution to a larger infrastructure segment.

The bottom line: - Molten salt tower CSP is emerging as a storage-backed solar option for grids that need clean power after dark, and the market outlook points to steady growth through 2030.
