Economic Viability of PV-Driven Hydrogen Systems in Off-Grid Electrification
Key Ideas
- Decentralized PV-driven hydrogen systems show lower levelized cost of energy and storage compared to PV-battery systems in off-grid applications.
- The hydrogen system's LCOE is €0.12/kWh with an LCOS of €0.35/kWh, outperforming the solar-plus-storage system's values of €0.17/kWh and €0.71/kWh.
- Researchers recommend investing in hydrogen storage due to future battery manufacturing challenges, despite slightly higher upfront costs.
- Study highlights the economic viability of hydrogen production for electricity storage applications in off-grid settings.
A German research team compared the economic performance of a decentralized PV-driven hydrogen system with a standalone solar-plus-storage system in Niger. The study revealed that the PV-driven hydrogen system achieved significantly lower levelized cost of energy and storage compared to the PV-battery system, with values of €0.12/kWh and €0.35/kWh, respectively. The analysis considered the energy requirements of a two-storey academic building in Niamey, Niger, with various appliances. The hydrogen system, comprising a 150 kW solar array, a PEM electrolyzer, a hydrogen tank, a fuel cell, and a battery, outperformed the solar-plus-storage system in terms of cost-effectiveness. Despite slightly higher upfront costs, the hydrogen system demonstrated better long-term economic viability due to the high cost of batteries. The study, published in the International Journal of Hydrogen Energy, emphasizes the potential of PV-driven hydrogen systems for off-grid electrification and storage applications. The researchers suggest that investing in hydrogen storage could be a favorable choice considering future challenges in battery manufacturing and conclude that the proposed project is feasible for deployment.
