Energy system requirements of fossil-free steelmaking using hydrogen
Iron and steel is the industrial sector with the highest level of greenhouse gas emissions, accounting for approximately 7% of global CO 2 emissions (Philibert, 2017).Over
Pilot plant demonstrates iron-based hydrogen storage feasibility
Three cases are presented: no storage; with day–night storage (e.g. batteries in households); and with both day–night and seasonal storage (detailed calculation in ESI Notes
Driving to Net Zero Industry Through Long Duration Energy
The first pumped storage plant was built in Zurich in 1891 at the Limmat river followed by a second installation 1894 at lake Maggiore and a third one 1899 at the Aare river. The principle

6 FAQs about [Steel plant energy storage case]
What is a thermal energy storage system based on a dual-media packed bed?
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.
What is the waste heat recovery potential of a steelmaking site?
Waste heat recovery is another critical issue. Zhang et al. highlighted that the waste heat recovery potential for a steelmaking site with the crude steel output of 10 Mt/a is 4.87 GJ/t, equal to 26.08% of the total energy consumption.
Can battery storage be used to produce steel in an EAF?
The use of battery storage can therefore be a method of providing electrical power for the production of steel in an EAF. The use of batteries to provide energy tend towards fast response times, and the correct energy practical minimum, 1.6GJ of electricity (440kWh) is required , , , .
Why is exergy important in steel production?
However, it has not been used for the entire iron and steel production site for optimizing the material and energy flow networks. Thus, it is necessary to use the concept of “exergy” in steelworks to identify specific processes or plants that have large exergy losses.
Can a packed bed thermal energy storage solution improve steelmaking waste heat recovery?
Even if the obtained values could be increased by the implementation of a different charge strategy, the presented analysis shows the potential of the packed bed thermal energy storage solution in the steelmaking waste heat recovery environment.
How can a high-capacity electricity storage bank help steel industry?
A method to improve this in the steel industry is the use of wind and solar as an electricity source feeding into a high-capacity storage bank. High-capacity electricity storage with a fast frequency response to discharge and fluctuation in energy demands will be required.
