Background

Carbon Offsets

In 2009, Salzgitter Flachstahl GmbH was the largest purchaser of offsets in the EU Emissions Trading Scheme.[1] Salzgitter Flachstahl GmbH purchased 40,000 offsets from an Indian steel project, an example that the campaign group Sandbag (now Ember) used in its report on how European companies were directly subsidizing competing industries in developing countries (see Clean Development Mechanism).[1]

Salzgitter Hydrogen Project

Salzgitter Flachstahl has launched a project called "Windwasserstoff Salzgitter" (or "Salzgitter Hydrogen") to offset CO2 emissions from their steel production.[2] A partner company, Avacon, plans to build seven wind turbines on the Salzgitter Flachstahl site, which will be used to power Salzgitter Flachstahl's PEM (Proton-Exchange Membrane) electrolysis plant (capacity of approximately 400 Nm3/hour).[2] Salzgitter Flachstahl will use hydrogen from this PEM electrolyzer to produce SALCOS® (Salzgitter Low CO2 Steel) as early as 2020.[2]

In December 2020, Salzgitter Group announced that they commissioned Tenova for construction of µDRAL, a demonstration plant for the production of Direct Reduced Iron, using up to 100% hydrogen as reducing agent. The plant is based on the ENERGIRON technology and will be installed on the premises of the Salzgitter steel mill at Salzgitter in Germany. The µDRAL will have a nominal production capacity of 100 kilograms per hour and will be operated with hydrogen and natural gas showing the flexibility of the technology in terms of fluctuating availabilities of reducing agents, including 100% hydrogen. The DRI produced by µDRAL will be both used in the blast furnace process to save injected coal and in the electric arc furnace of the Peine plant.[3]

Transition

Salzgitter Flachstahl has announced a plan to cut emissions from the plant by 95% by 2033; they will have 3 phases, phasing out BF capacity entirely by 2033, replacing them by hydrogen-based direct reduction process. The first of these plants is expected to begin operations in 2026.[4] The project involves two direct reduction plants and three electric arc furnaces to replace existing blast furnaces and basic oxygen converters.[5]
