Grey Hydrogen
Both green and blue hydrogen can achieve environmental goals. Today, blue hydrogen can provide industrial-scale volumes of carbon-neutral hydrogen, while green hydrogen will increase deployment of renewable power generation. 7 Centralized hydrogen production from renewable electricity is one of the paths to source cost- effective green hydrogen at scale. Future energy systems will likely be challenged by large quantities of stranded renewable electricity that cannot be used in the conventional electrical grid. Using this surplus electricity for electrolysis will produce low cost green hydrogen for a variety of uses, including as transportation fuel.
Currently, 95% of hydrogen is produced from fossil fuels, emitting some CO 2 . Blue Hydrogen Grey hydrogen whose CO 2 emitted during production is sequestered via carbon capture and storage (CCS).
Green Hydrogen
Low or zero-emission hydrogen produced by electrolysis of water using renewable energy sources.
