But a complete assessment of decarbonization pathways must also consider non-renewable low-carbon sources: Nuclear fission: Mature technology, controversial politics Nuclear fusion: The eternal promise, now perhaps closer Carbon capture and storage (CCS): Making fossil fuels “clean” Hydrogen from fossil sources: Currently the dominant production method ...
