Breakthrough photo voltaic know-how to assist produce emissions-free cement
Clinker manufacturing
Clinker is produced by fusing limestone, clay, and different supplies in a rotary kiln at temperatures nearing 1500°C. Polluting fossil fuels are historically used to warmth the kiln and are answerable for roughly 40 p.c of the direct CO2 emissions of the method.
Synhelion’s breakthrough know-how delivers high-temperature course of warmth past 1500°C.
“Cement produced with photo voltaic power is an thrilling know-how with super potential to cut back the carbon footprint of cement manufacturing,” stated Fernando A. González, CEO of CEMEX.
“Attaining our web zero carbon purpose by 2050 would require relentless innovation reminiscent of this to find and scale breakthrough applied sciences.”
Shut-up of Synhelion’s photo voltaic receiver, which offers the required course of warmth to decarbonize clinker manufacturing.
The brand new challenge will have a look at strategies to cut back carbon dioxide emissions, decrease course of temperatures, and improve the effectivity of clinker formation utilizing photo voltaic power.
“Few renewable applied sciences are able to producing warmth on the temperatures wanted to course of uncooked cement feedstock,” stated Nathan Schroeder, Sandia researcher and principal investigator for the Photo voltaic MEAD challenge.
“This challenge will advance our understanding of the way to use concentrating photo voltaic know-how to collect and ship the warmth to present cement manufacturing amenities and could have crosscutting relevance to different ore processing industries reminiscent of refractory, ceramics, and battery manufacturing.”
