Solar Power Generation Installed on Cement Plants: The
The cement sector accounts for 8% of global CO₂ emissions – that''s more than all trucks worldwide combined. With net-zero deadlines looming, solar power generation installed on
Location and DNI availability of the investigated plant A conventional cement plant (Kotputli Cement Works (KCW), an UltraTech Cement Limited manufacturing unit) at Kotputli, Jaipur, Rajasthan, was investigated for solar thermal application.
There is no way that a solar cement plant can run continuously throughout the whole solar day. Therefore, several assumptions/constraints and modifications are considered and included in this model. The model is considered a solar calciner, constructed and tested at the German Aerospace Centre (DLR).
Best approach to integrating the CST technology in a conventional cement plant is to use solar tower system with solar reactor at the top of the solar tower or preheater tower. Additionally, the use of non-conventional sources of energy in cement production reduces a lot of anthropogenic emissions to the atmosphere.
Scaling up solar reactors, transportation system for raw and calcined material, and storing of calcined materials are the major barriers. Conventional cement plant that is situated in a location with a DNI value of more than 438 (W/m 2) can use this solar design model. It must have adequate land for installing a large number of heliostats.
