Energy conservation in coal based dri plants
WebMay 26, 2024 · It is clear that we need more action to increase the share of renewables and call out “hydrogen-ready” plants that are using grey hydrogen or natural gas. While there are some promising projects, it seems unlikely that DRI production with green hydrogen will account for 100% of EU steel production in 2050. There is a race for producing the first … WebJun 7, 2024 · Rio Tinto and other steel and mining groups have highlighted the need to adapt processes for DRI plants which have traditionally run on reformed natural gas as new plants are developed for 100% hydrogen-based reduction. Many such projects expect to create hydrogen for DRI with electrolysis using renewable power from wind and solar …
