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]

In February, 2025, the company began construciton of a 100MW electrolysis plant for the production of green hydrogen. The plant will be one of the largest in Europe and, starting in 2026, will generate around 9,000 tonnes of green hydrogen a year.[4] However, it is estimated that Salzgitter will need 150,000 tonnes of hydrogen annually for SALCOS phase 1, and hydrogen deliveries cannot begin until 2029 when the comany is connected to the new hydrogen pipelines that the German government is planning to build.[5]

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.[6] The project involves two direct reduction plants and three electric arc furnaces to replace existing blast furnaces and basic oxygen converters.[7] Phase 1 of the transition plan involves the construction of a DRI plant, an EAF, and a 100MW electrolysis plant. In 2023, Salzgitter awarded a contract to Tenova, Danieli, and DSD Steel group for the construction of the first DRI plant. Financing for the entirety of phase 1 was secured via subsidies from the Federal Republid of Germany and the State of Lower Saxony, totally around €1 billion.[8] Additionally, in 2024, Salzgitter signed a power purchase agreement (PPA) with Iberdrola to supply 900GWh of solar power over the coarse of 15 years from Iberdrola Deutschland's 60 MW PV plant.[9]
