Efficiency and Energy Consumption in Steel
Modern steel production uses electric arc furnaces that can recycle scrap steel, reducing energy consumption compared to traditional
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, , , .
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.
Moreover, electricity plays a predominant role, especially in electric arc furnace (EAF) operations, which melt scrap metal and can be powered by renewable sources to further improve the energy profile of steel manufacturing.
The integration of renewables into steel production is not only an environmental imperative but also a strategic decision to safeguard against volatile fossil fuel prices and strengthen energy security. Solar and wind power are the frontrunners in this transition.
