Problem
Industrial steam generation and thermal energy storage rely heavily on fossil fuels, and existing concentrated solar power (CSP) systems are often too expensive, land-intensive, and inefficient for widespread adoption. Parabolic trough designs, in particular, require costly manufacturing and maintenance while leaking significant amounts of inbound sunlight, limiting their economic and practical viability.
Solution
DoSun Power provides a patented solar collector that maximizes inbound thermal energy capture through a mirrored collector tube design, achieving temperatures greater than 500°C during peak sunlight with 85% efficiency and roughly 3kW per unit. The system uses durable steel frames and acrylic lenses, making it robust and inexpensive to produce while reducing the land footprint to just 2x2 square meters per unit—about one-sixth the area of standard CSP installations. Each unit is remotely controllable and can be powered on or off as needed, while modular construction allows multiple units to be connected in series for scalable energy output. The technology is specifically designed to decarbonize steam generation and improve thermal battery efficiency throughout the day, offering a cost-effective alternative to conventional solar thermal systems.
Target Audience
Primary customers are industrial facilities and energy providers seeking to decarbonize steam generation, as well as operators of thermal battery systems looking to increase efficiency and reduce land requirements for solar thermal installations.
