If you are an IPP dealing with high operational costs and energy loss in solar fields — this project developed a fix-focus parabolic trough that increases annual electrical output by 24.5% and reduces solar field costs by 30%. It allows for dispatchable power at 555°C using molten salts.
High-Efficiency Solar Thermal Collectors for Industrial Heat and Power Storage
Imagine a giant magnifying glass that tracks the sun, but instead of moving the pipe that carries the heat, only the mirror moves. This keeps the heat-carrying liquid in one long, steady line, which stops leaks and saves money. It also uses a special salt that stays hot for a long time, acting like a giant thermal battery for the grid.
What needed solving
Traditional parabolic trough plants suffer from high heat losses, expensive flexible piping, and significant wind-load stress on structures, which increases both CAPEX and OPEX.
What was built
A fix-focus parabolic trough system with a detached absorber tube, biodegradable sandwich mirrors, and an automatic water-recycling washing device.
Who needs this
Who can put this to work
If you are a glass manufacturer dealing with fragile and inefficient solar mirrors — this project developed biodegradable thin-glass sandwich mirrors that increase optical efficiency by 2% due to better reflectivity.
If you are an O&M provider dealing with high water consumption and dust-related efficiency drops — this project developed an automatic mirror washing device that recycles about 90% of washing water and increases performance by 4%.
Quick answers
How does this technology reduce the initial investment cost?
It eliminates collector connection piping and all flexible connections in the solar field. Additionally, wind loads are reduced by 75%, allowing for lighter and cheaper steel structures, pylons, and foundations.
What is the industrial scale of the demonstration?
The project involves erecting and testing a 350m-collector with an aperture of 6.7m using molten salt at the EMSP.
Are there licensing or IP details available?
Based on available project data, specific IP or licensing terms are not mentioned; however, the project involves a consortium of 7 partners including 3 industrial entities.
How does it handle energy loss during non-productive hours?
The project is testing and optimizing an 'overnight drainage strategy' specifically to eliminate heat losses during the night.
What is the expected timeline for results?
The project period runs from 2023-10-01 to 2027-11-30, with major demonstration results expected closer to the end of the project.
Who built it
The consortium is well-balanced for commercialization, featuring a 43% industry ratio with 3 industrial partners and 4 SMEs. The collaboration spans 5 European countries (DE, ES, FR, IT, PT), combining the academic oversight of Universidade de Évora with practical research and industrial manufacturing capabilities.
