RFNBO
Acronym for: Renewable Fuel of Non-Biological Origin
EU designation for green hydrogen that meets strict additionality, geographic, and temporal correlation rules.
Detailed Explanation
RFNBO (Renewable Fuel of Non-Biological Origin) is the EU designation for hydrogen made with renewable electricity. To qualify, projects must prove: (1) additionality β the renewable plant was built specifically for the hydrogen project; (2) geographic correlation β production and consumption in the same bidding zone; (3) temporal correlation β hourly matching of renewable generation with hydrogen production. RFNBO is the key compliance framework for EU green hydrogen subsidies. Solar farms co-located with electrolyzers meet RFNBO most easily.
