Hydrogen role in the valorization of integrated steelworks process off-gases through methane and methanol syntheses

The valorization of integrated steelworks process off-gases as feedstock for synthesizing methane and methanol is in line with European Green Deal challenges. However, this target can be generally achieved only through enrichment hydrogen use cutting-edge syntheses reactors coupled to advanced control systems. These aspects are addressed the RFCS project i 3 upgrade central role was evident from first stages project. First stationary scenario analyses showed that required amount significant existing renewable production technologies not ready satisfy demand an economic perspective. poor availability low-cost green one main barriers producing further highlighted application ad-hoc developed dispatch controller managing intensified steelworks. considers both environmental impacts cost function and, although benefits obtainable by exploiting syntheses, current costs highly affect decisions. This underlines need big scale processes dedicated markets hydrogen-intensive industries, which would ensure easy access fundamental gas paving way a C-lean more sustainable steel production.
