A study from the Stockholm School of Economics highlights the importance of hydrogen sourcing in the competitiveness of green steel production in Romania. The research focuses on Liberty Steel Galați's transition to low-carbon steelmaking using green hydrogen and electric arc furnace-based technologies to achieve carbon neutrality by 2030. The study suggests that if hydrogen is produced on-site and electricity prices remain stable, Romanian green steel production can be competitive. However, if hydrogen is externally purchased, a 15% price premium in the market would be necessary to avoid significant value losses. The research points out that the transition of Liberty Steel Galați could serve as a blueprint for green steel production in Central and Eastern Europe, contributing to the EU's climate neutrality goals. The study also reveals that the premium for green steel production in Romania could vary greatly depending on the sourcing of hydrogen, emphasizing the importance of stable electricity pricing, green energy production, hydrogen infrastructure, and supportive policies. The findings indicate that full on-site hydrogen production would increase electricity demand significantly, requiring electricity from fossil-free sources to qualify as climate neutral. The study's limitations include uncertainties in forecasting future electricity prices, hydrogen infrastructure readiness, and policy interventions. The research concludes by highlighting the practical implications for both industry and policymakers, stressing the necessity for stable electricity pricing, green energy production, hydrogen infrastructure development, and supportive policies to ensure the financial viability of low-carbon steel production.
