MIDREX H2 - The Road to CO2-Free Direct

Reduction

ABSTRACT ： The iron and steel industry must reduce CO2 emissions drastically

during the next 30 years. The EU target is an 80% reduction by 2050, which can only

be achieved by different production processes. To prepare, many steel producers plan

to integrate a direct reduction (DR) plant in their existing steel works. This paper

describes the Midrex H2 plant configuration for stepwise increase up to 100% H2

input. An overview about currently ongoing H2 plant projects based on Mi 由 ex shaft

furnace technology will be given. Furthermore, a feasibility and case study of a DR

plant operation based on H2 will be presented.
