Perovskites Can Reduce Carbon Emissions From Blast Furnaces
readers, perovskites are something used in solar panels to make electricity. Now it appears they may have other uses as well. Researchers at the University of Birmingham in the UK have recently published a report in theCost effective decarbonisation of blast furnace – basic oxygen furnace steel production through thermochemical sector coupling.
“The CO produced by the TC cycle replaces expensive metallurgical coke for the reduction of iron ore to metallic iron in the blast furnace . The CO2 produced from the BF is used in the TC cycle to produce more CO, therefore creating a closed carbon loop, allowing for the decoupling of steel production from greenhouse gas emissions.
The iron and steel sector is a major greenhouse gas emitter, releasing up to 9% of global CO2 emissions. Steel is firmly in the category of hard-to-decarbonize sectors due to the inherent carbon-intensive nature of its production. Indeed, more carbon dioxide is released on a weight basis than steel produced, with 1.89 tonnes of CO2 released for every ton of steel produced.
There are a few technologies that are being researched to decarbonize the steel industry. The first option is to close the old BF-BOFs and replace them with DRI-EAFs. If the EAF is powered by renewable electricity, it has the potential to save 1.5 Gt of CO2 emissions annually. However, a DRI-EAF plant costs between $1.1 and $1.
