Nauru’s energy mix is almost entirely dependent on imported fossil fuels, primarily diesel, which accounts for approximately 90–95% of its electricity generation. The remaining portion is supplied by solar energy.

Nauru is actively integrating green hydrogen into its long-term strategy to achieve 100% renewable energy by 2050. The island’s approach focuses on utilizing its abundant solar resources to produce carbon-free fuel, potentially serving as a model for other Pacific island nations.

In August 2025, a $1 billion investment proposal from China was announced, which specifically includes the development of renewable energy and green transport projects in Nauru. The country expects to reach 50% renewable energy in 2026 through the expansion of small-scale solar farms, providing the necessary renewable electricity base for future hydrogen electrolysis.

International partners like Masdar have already implemented solar projects on the island, laying the groundwork for integrated renewable systems

Nauru is a participant in the Pacific Hydrogen Strategy, a regional initiative aimed at mapping energy resources and infrastructure to establish a hydrogen economy across Pacific Island Countries and Territories (PICTs).
