Zimbabwe is on the brink of a significant transformation in its steel industry as Chinese multinationals make substantial investments in the country's steel production sector. This influx of over £3.8 billion from Tsingshan Holding Group and Xinganglian Metallurgical positions Zimbabwe to become Africa's largest steel producer, surpassing current leaders in the continent. However, the country now faces a critical decision between continuing with 'brown' steel production, which heavily relies on fossil fuels like coal, or transitioning towards 'green' steel production that prioritizes sustainability and minimizes carbon emissions. This choice is crucial not just for Zimbabwe's economic growth but also for its environmental impact and alignment with global efforts to combat climate change. The article highlights how the use of coal in steel production contributes significantly to carbon emissions and outlines the potential consequences of sticking with 'brown' steel, especially in light of regulations like Europe's Carbon Border Adjustment Mechanism that may limit the competitiveness of brown steel in international markets. Despite the challenges, the technologies required for green steel production are available, with the introduction of electric arc furnaces and the possibility of using green hydrogen from Namibia as alternatives to coal. The shift to green steel not only reduces carbon emissions but also presents opportunities for value addition and growth in Zimbabwe's steel industry. The investments from Chinese firms bring advanced technology and expertise in green hydrogen and electric arc furnaces, setting the stage for the transfer of skills and knowledge to local engineers and technicians. This transition to green steel could enhance Zimbabwe's industrial value chain by adding value through the production of stainless steel using energy transition minerals like nickel and chromium. Overall, the article emphasizes the importance of Zimbabwe's decision in choosing between brown and green steel production, not just for the steel industry but for the country's sustainable future.
