Technology Development for Hydrogen Steelmaking

摘要

Reducing CO2 emissions by around 80 percent by the year 2050 is the central climate goal, and requires both energy suppliers and industry to prepare themselves and explore new pathways together. For the industry, transport, and energy sectors, C02-free hydrogen is an important source of energy for sector coupling and can significantly contribute to achieving the climate goals. The vision is to move away from carbon via bridging technologies based on natural gas, as is already the case at the direct reduction plant of voestalpine in Texas and finally on to the greatest possible use of green hydrogen in steelmaking. The prerequisite is the provision of sufficient energy from renewable sources and at competitive prices. Construction of the new PEM pilot plant for theproduction of C02-free hydrogen together with research on other breakthrough technologies like hydrogen plasma smelting reduction is a step further towards the long-term realization of a technology transformation in the steel industry in the next couple of decades.
