Development trend of solar container heating

How has solar process heat changed in 2022?

Even if the total number of documented solar process heat systems has not increased, it is remarkable that after two years with relatively small systems, the average system size has more than tripled compared to the systems installed in 2022. The second change in the market concerns the types of collectors used.

Which market influenced the distribution of solar thermal collectors in China?

Similar to the distribution by type of solar thermal collector in total numbers, the Chinese market influenced the overall figures the most. 28% of all newly installed systems in China were thermosiphon systems, while pumped systems accounted for 72%. The share of thermosiphon systems has decreased in China for several years (Figure 51).

What is the market for solar thermal systems for industrial processes?

Although the market for solar thermal systems for industrial processes (SHIP) fluctuates in the number of systems installed per year and the annual installed capacity, it is a relatively stable market. Between 2017 and 2023, approximately 100 new SHIP systems with an average capacity of 1.1 MW commissioned each year.

What is solar heat for industrial processes?

In November 2019, the IEA Solar Heating and Cooling Programme defined solar heat for industrial processes (SHIP systems). This definition refers only to the collection and documentation of SHIP systems in this Solar Heat Worldwide report. All solar thermal systems, direct or indirect (via heat storage) connected to an industrial process.

Is solar thermal cooling still a niche market?

Solar thermal cooling is still a niche market, with over 2,000 systems deployed globally as of 2023. Due to changing distribution channels and B2B sales of the sorption chillers, tracking newly installed solar-driven systems is difficult and can only be estimated.

Can solar thermal systems be used for high-temperature industrial processes?

Electrification can be a solution for certain high-temperature industrial processes, such as steel production. For industrial low-temperature process heat up to 400°C, solar thermal systems are an excellent option. More than a thousand systems operating across various industry sectors worldwide impressively demonstrate this.
