St. Kitts and Nevis is overwhelmingly dependent on imported fossil fuels, with diesel generators producing at least 94%–98% of the country’s electricity. Renewable energy, mainly solar and wind, contributes a small, growing, but still limited portion (approx. 4-5%) of the energy mix. The islands are actively transitioning toward renewable sources like geothermal, solar, and waste-to-energy.

St. Kitts & Nevis is actively positioning itself as a potential green hydrogen hub in the Caribbean, aiming to become a net exporter of renewable energy. The government is leveraging partnerships for geothermal, solar, and wind projects, with strong interest from the EU to source hydrogen from the region.

As of February 2026, there’s no information indicating that St Kitts & Nevis is producing green hydrogen from electrolysis of seawater.
