24.3 Case Study of a Steel Plant. A steel plant consumes a huge amount of energy. Studies have been undertaken for many years on energy saving, and a great deal of equipment has also been introduced to significantly improve energy efficiency. Bisio and Rubatto (2000) studied the energy saving in coke-oven plants.

Steel, as a cornerstone of modern economies and a linchpin of the energy transition, is responsible for approximately 8% of global energy demand and 7% of energy sector CO2 emissions (IEA, 2020). The imperative of reducing these emissions by at least 50% by 2050 ( IEA, 2020 ) is challenged by the steel industry''s heavy coal …

A thermal energy storage system based on a dual-media packed bed is proposed as low-cost and suitable technology, using a by-product produced in the same plant, the steel slag, as filler material. The main objective of this system is to achieve a continuous heat supply from the inherent batch operation of the steel furnace.
