The steel industry requires $1.4 trillion investment by 2050 to achieve net-zero emissions, facing 30% cost increases by 2040. Hydrogen-based direct reduced iron technology offers 76% emission reductions but requires green hydrogen costs declining to $1.70 per kilogram. Financing mechanisms include government grants exceeding €5 billion in Germany, green loans from over 50 financial institutions, & equity from specialized funds. H2 Green Steel secured €450 million Series B funding & €3.5 billion debt financing for its Swedish facility, obtaining 95% offtake commitments worth €3.29 billion before construction, exemplifying customer-supported project finance models for green steel ventures.
