Preface to the Special Issue on 'Green Energy Ironmaking and Steelmaking: Production of Green Energy and Its Use in Ironmaking and Steelmaking'

摘要

The use of green energy (hydrogen) in the steel industry is becoming important for decreasing CO_2 emission. The development of a proper method for green hydrogen production that can reduce the consumption of fossil fuels to a minimum using waste heat and COG from steel plants, biomass, and/or nuclear energy will be an important contribution. In addition, the use of green hydrogen in the ironmaking and steelmaking processes is essential. However, problems arising from the positive use of hydrogen must be clarified and resolved.
