Most renewable energy technologies are now at the commercial level: Their innovation stage is over. Careers now tend to be more in construction, factory production, logistics, or sales. However, in one solar technology, there is still the need for the innovative. In Tower Concentrated Solar Power (CSP), where a solar field of heliostats encircles a solar receiver atop a central tower, innovation is still needed to reduce heliostat costs to enable deployment growth. The heliostats account for about 30% of the cost. “There’s still a need to continue innovation in heliostats,” noted Rebecca Mitchell, a researcher at the Concentrating ...

The recycled concrete aggregate produced met the requirements for typical structural applications.

RESEARCHERS at the Indian Institute of Technology Madras have developed a treatment process involving solar thermal energy to recycle concrete debris from construction sites and demolitions. A team of researchers from IIT Madras has developed a treatment process involving solar thermal energy to recycle concrete waste.

“De pequeña me gustaban mucho las matemáticas, los juegos de lógica, los retos matemáticos, los libros de resolver enigmas... En la casa de mis abuelos había un cuento, ‘Las aventuras de la Mano Negra’, en el que un grupo de niños y niñas se reunían para resolver un caso policiaco, siguiendo pistas. Y a mí me fascinaba imaginar que era una de esas niñas”, dice Lidia Roca, y sonríe con sus recuerdos. “Bueno, al final, supongo que esas ganas de resolver misterios tienen algo que ver con el método científico...”. Lidia nació en Madrid, pero un mes después su familia ...

This paper reports on the development of a hierarchical control strategy for a multi-generation solar plant. The plant includes a linear Fresnel reflector, an organic Rankine cycle, an absorption chiller, a thermal storage tank, circulation pumps, and valves. The hierarchical control strategy consists of three successive layers in addition to a wireless monitoring system. The first layer is a supervisory control layer which is responsible for selecting the appropriate operating mode of the plant depending on the current state, user demand, and weather data. The second layer is concerned with determining the reference temperature for the maximum yield from the ...

On its completion, the project will have the largest thermal storage capacity in the world of 15 hours, allowing for energy availability around the clock. The production capacity of clean energy in Dubai has reached 2,027 megawatts (MW) using photovoltaic solar power (PV) and concentrated solar power (CSP). This is about 14 percent of Dubai’s total power production capacity of 14,517 MW. Saeed Mohammed Al Tayer, MD and CEO of Dubai Electricity and Water Authority (DEWA), made the announcement during his visit to the Mohammed bin Rashid Al Maktoum Solar Park, which DEWA is implementing. This is ...
