thyssenkrupp greenlights construction of €2B hydrogen-powered direct reduction plant for low-CO2 steel

Green Car Congress

As part of its tkH2Steel transformation project, coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants. Thus, the Duisburg steelworks is continuing to boil steel as in the past—but with hydrogen and green power instead of coal. —Martina Merz, CEO of thyssenkrupp AG. With its capacity of 2.5

Kobe Steel demonstrates technology that can reduce blast furnace CO2 emissions by ~20%

Green Car Congress

The quantity of CO 2 emissions from the blast furnace is determined by the reducing agent rate (RAR)—the coke rate (determined by the quantity of coke used in blast furnace) plus the pulverized coal rate (determined by the quantity of pulverized coal injected into blast furnace). Coke is carbon fuel made from coal.

RWE and ArcelorMittal intend to build and operate offshore wind farms and hydrogen facilities for low-emissions steelmaking

Green Car Congress

The partnership centers on driving forward the production of carbon-neutral steel, with a plan to replace coal with wind power and green hydrogen as the main source of energy in steel production at ArcelorMittal’s steelmaking sites in Germany. Industry needs both in large quantities as soon as possible in order to achieve its climate targets.

Largest pilot plant for CO2-neutral production of hydrogen begins operation at voestalpine site in Linz

Green Car Congress

The global climate goals of almost completely eliminating CO 2 emissions by 2050 pose challenges for industrial enterprises and energy suppliers, and demand new technological solutions in both sectors. In this context, CO 2 -neutral (“green”) hydrogen is regarded as a promising future option for facilitating the energy transition.

Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.
