Brazilian mining company Vale has announced a partnership with Green Energy Park (GEP) to explore opportunities for green hydrogen production in Brazil. This collaboration is significant as Brazil looks to develop its green hydrogen industry to facilitate its energy transition. Vale, on the other hand, is focusing on implementing low-carbon initiatives in the steel industry in alignment with its goal to achieve net-zero carbon emissions by 2050. The joint efforts of Vale and GEP will involve evaluating the feasibility of establishing a green hydrogen plant in Brazil. This plant would eventually supply a 'mega hub' that Vale aims to develop in the country. Vale plans to produce iron ore agglomerates in these mega hubs, using renewable hydrogen as a reducing agent, which would be essential for the production of hot-briquetted iron. Green hydrogen, produced through the electrolysis of water using renewable power sources, has emerged as a key solution for reducing emissions in sectors that are challenging to decarbonize, such as transport and steelmaking. Earlier collaborations by GEP with Brazil's Eletrobras and Vale's partnerships with H2GS and Hydnum Steel indicate a growing focus on building 'mega hubs' in various countries as part of the companies' decarbonization strategies.
