Slovakia’s energy mix is heavily decarbonized, with over 85% of electricity generated from low-carbon sources as of 2023. Nuclear power is the dominant source, providing approximately 61–63% of electricity. Hydropower (14–17%), biomass (5%), and small amounts of solar and natural gas make up the rest of the generation.

Slovakia is rapidly developing its green hydrogen sector to decarbonize industry and transport, aiming to become a key regional hub. Key initiatives include the EastGateH2V project in Košice (starting 2027), investment in electrolyzers for grid stability (Veolia/RoyalStav), and government-backed funding (€13.5 million) to support production.

As of February 2026, there’s no information indicating that Slovakia is producing green hydrogen.
