When energy is needed in the form of heat, it is more economically beneficial to utilise direct solar thermal energy using solar collectors. Solar cells that directly convert sunlight to electricity are only able to make use of a small part of the solar spectrum, where maximum efficiency typically lies around 20%. Solar collectors are on the other hand in theory able to exploit the entire spectrum, with a maximum efficiency of 70-90 %.
Solar energy can, depending the specific temperature needed, be collected using planar solar collectors or concentrated solar power. Planar collectors are well suited for hot water production and space heating, while concentrated power can be used to produce steam and high-temperature heat for industrial use, power production or in CCS (carbon capture and storage). The exploitation of solar heat has a high potential to reduce industrial greenhouse gas emissions considerably through the replacement of fossil fuelled steam production.
SINTEF has broad competence within design of thermal systems for production, utilization and storage of solar heat, both at component and system level, as well as insight into the industry's need for heat and steam. The need for heating in one process is commonly combined with the need for cooling in another, and SINTEF has a long history within design of heat-driven cooling processes suited for system integration.
