文摘
The transfer of our fast growing society from a carbon based to a low carbon based economy/production within the next decades is the global megatrend which has been discussed now for many years. The target of minus 80 % can only be achieved by a transfer of the global energy system. Today we have a portfolio of technologies available to reduce the CO2 intensity further, but, without consideration of the two limitations of plant lifetime and carbon lean energy, a successful transfer will not be possible, and every company and country has its own timeline for this process. The forced use of natural gas can act as a bridge technology for the transfer between the energy systems. HBI and DRI allow a broad flexibility for the EAF steel production route as well as for the integrated BF/BOF steel production. The start-up of the voestalpine DR plant in the US is an important step to meet the challenges of the next decades.
