Solution (b)
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications. It can be used in cars, in houses, for portable power, and in many more applications.
Grey Hydrogen: Most hydrogen nowadays comes from natural gas. It is bonded with carbon and can be separated from it via a process involving water called “steam reforming”, but the excess carbon generates CO2. This hydrogen is called grey whenever the excess CO2 is not captured. Grey hydrogen accounts for most of the production today and emits about 9.3kg of CO2 per kg of hydrogen production.
Blue Hydrogen: Hydrogen is considered blue whenever the emission generated from the steam reforming process are captured and stored underground via industrial carbon capture and storage (CSS), so that it is not dispersed in the atmosphere.
Pink Hydrogen: The colour pink is often used for hydrogen obtained from electrolysis through nuclear energy.
Green Hydrogen: Green hydrogen, often also called “clean hydrogen” is produced using electricity generated from renewable sources and currently accounting for around 1% of the overall hydrogen production. Today, green hydrogen is two to three times more expensive than blue hydrogen.
