In Nigeria, the reliance on off-grid diesel generators for energy production has led to a project focusing on exploring green hydrogen technologies as a sustainable alternative. The initiative aims to leverage unused solar PV capacity to generate and store green hydrogen, which can be used for electricity generation or exported. By targeting the mini-grid system in Gbamu-gbamu, Ogun State, the project demonstrates the feasibility of integrating green hydrogen solutions into existing infrastructure. The study's outcomes, including technical design optimizations and economic feasibility, have attracted attention from stakeholders interested in decarbonization and the green hydrogen economy. With a strong government push towards cleaner energy sources and rising operational costs of diesel generators, the transition to green hydrogen presents a promising pathway for Nigeria's energy sector. The pilot project serves as a step towards reducing reliance on fossil fuels, improving energy access, and promoting sustainability in the country.
