Abstract: This work presents the first systematic review analysis of potential Power to Gas integrations in blast furnace ironmaking. The primary objective of the paper is to evaluate the PtG technology implementation in both conventional air-blown and full oxygen blast furnaces, considering different BFG recycling routes (upper, shaft or tuyeres), and synthetic gases (SNG, H2 or syngas). Employing a systematic methodology, the paper compares all the studies using 14 Key Performance Indicators (KPI) and elaborates a discussion on the main findings and limitations, proposing areas for future research. PtG application enables air-blown blast furnaces to cut emissions to 1060 kgCO2/tHM. With PtG and top gas recycling, oxygen blast furnaces achieve a reduction to 747 kgCO2/tHM, and when combined with geological storage, the reduction further drops to 435 kgCO2/tHM. Additionally, the authors propose a novel PtG-ironmaking integration based on the findings of this paper.
