The West African Science Service Centre on Climate Change and Adapted Land Use (WASCAL) has highlighted the potential for Nigeria to generate four million tonnes of green ammonia annually by 2060. This achievement can significantly reduce the country's dependence on imported fertilisers and create numerous green jobs across the value chain. The Nigeria4H2 project, implemented in collaboration between WASCAL and various universities, aims to assess the technical, infrastructural, regulatory, and investment landscape to leverage Nigeria's green hydrogen potential for transportation, electricity production, and the manufacturing of fertilisers based on green ammonia. This initiative seeks to enhance national food security, support farmers, and promote sustainability in agriculture. By integrating green hydrogen into agricultural policy through green ammonia, Nigeria can boost productivity, reduce reliance on imported fertilisers, and establish itself as a key player in the global green economy. The need for a national green hydrogen strategy, public-private partnerships, tax incentives for investors, and the establishment of a robust National Hydrogen Policy are emphasized to accelerate the country's transition towards green energy and agricultural sustainability. The project is aligned with President Bola Tinubu's Renewed Hope Agenda and aims to drive advancements in green technology, research, and innovation for a more environmentally friendly and energy-independent Nigeria.
