This paper conducts a techno-economic assessment and proposes a regional roadmap for producing green hydrogen for Nigeria's industrial clusters. It leverages the country's combined solar photovoltaic and hydropower resources. The study developed an integrated modelling framework to co-optimise renewable energy supply, electrolyser operations, hydrogen storage and distribution, and demand aggregation across various industrial sectors like cement, ammonia, and steel. A levelised cost of hydrogen model, adapted for Nigerian financial conditions, was used for scenario and sensitivity analyses. Results indicate that a hybrid solar-hydro configuration significantly improves electrolyser capacity factors and reduces hydrogen production costs by 10-25% compared to solar-only systems. This approach can meet up to 70% of industrial cluster hydrogen demand in the initial deployment phase. The research also outlines a phased roadmap and policy recommendations to facilitate investment and regulatory frameworks.
This research is important because it offers a practical strategy for Nigeria to produce clean hydrogen using its abundant renewable energy sources. By showing how a combination of solar and hydro power can efficiently supply hydrogen to industries, it provides a pathway for decarbonising key sectors and reducing reliance on fossil fuels, contributing to environmental sustainability and energy security.
This research provides a detailed techno-economic model and a regional roadmap for green hydrogen production, directly supporting industrial decarbonisation efforts in Nigeria. It could inform investment decisions for energy developers and industrial companies in sectors like cement, ammonia, and steel, enabling the adoption of cleaner energy. The proposed policy instruments suggest a near-market application, guiding public-private partnerships and regulatory bodies in developing a green hydrogen economy.

This paper presents a techno-economic assessment and regional roadmap for the deployment of green hydrogen production targeted at Nigeria’s industrial clusters by leveraging the country’s complementary renewable resource mix — utility hydropower and distributed utility-scale solar photovoltaic (PV). The study develops an integrated modelling framework that co-optimizes (i) renewable supply dispatch (hydro + solar), (ii) electrolyser sizing and operating strategy, (iii) hydrogen storage and short-distance pipeline distribution, and (iv) demand aggregation across industrial clusters (cement, ammonia, steel/metal processing, refined petrochemicals and heavy transport). A levelized cost of hydrogen (LCOH) model tailored to Nigerian financial conditions is presented, together with scenario analysis (Solar-Only, Hydro-Only, Solar-Hydro Hybrid) and sensitivity testing against key parameters (electrolyser CAPEX, renewable capacity factor, grid curtailment, water cost, and financing rate). Results show that the hybrid solar–hydro configuration improves electrolyser capacity factor substantially (40–60% vs. 15–35% for solar only), reduces LCOH by 10–25% compared with solar-only baselines, and enables dispatchable hydrogen supply that meets up to 70% of cluster hydrogen demand during the first deployment phase. The paper further proposes a phased regional roadmap (2026–2050) and policy instruments to mobilize public-private investment, local manufacturing, water-use management, and regulatory frameworks for offtake, transport and safety. The study fills a critical gap in Nigeria’s energy planning literature by providing the first cluster-level, hybrid renewable techno-economic model and a practical roadmap for green hydrogen integration into industrial decarbonization strategies.
