Petrobras has announced plans to construct its inaugural pilot plant for renewable hydrogen production in Alto do Rodrigues, Rio Grande do Norte. This initiative, set to be executed in collaboration with the Senai Institute for Innovation in Renewable Energies (Senai ISI-ER) and WEG, a renowned Brazilian electrification company, will be situated at the Vale do Açu Thermoelectric Power Plant. With a substantial budget of R$ 90 million, the project is slated to commence operations in early 2026. The core process for generating renewable hydrogen will involve electrolysis of water powered by solar energy, a method that disintegrates water molecules into hydrogen and oxygen using an electric current. This endeavor is pivotal in Petrobras' decarbonization strategy, signaling the initial phase towards future commercial ventures in the sustainable hydrogen sector. By opting for renewable hydrogen production through solar-powered electrolysis, Petrobras aims not only to diminish greenhouse gas emissions but also to advocate for the utilization of abundant and sustainable natural resources in Brazil. The forthcoming electrolysis plant, which will be trialed in diverse operational modes, will leverage the existing electrical grid connection and energy storage system at the Alto Rodrigues Photovoltaic Plant, which will undergo a capacity expansion from 1.1 MWp to 2.5 MWp. The hydrogen output is set to be employed in energy production and investigations on the blending of hydrogen with natural gas to fuel microturbines, a pioneering move by Petrobras to assess the operational efficiency and structural resilience of this hybrid mix. Notably, Petrobras is spearheading research on the impact of integrating renewable hydrogen into natural gas for microturbine applications, marking a pioneering initiative within the Brazilian energy landscape.
