Focus has shifted from fossil fuels to renewable sources in order to meet the world's growing energy demand while protecting the environment. Being a flexible fuel, hydrogen is thought to have a big influence on the energy industry. It would soon become the first fuel of choice due to its high energy density, quick burning speed, high octane rating, and zero possibility for injury. Therefore, it is necessary to find a
sustainable hydrogen source to take the place of fossil fuels. The majority of hydrogen produced now comes from fossil fuels, which will run out by 2050.One efficient technique for creating renewable hydrogen is steam gasification. In addition to offering a sustainable source of hydrogen, using biomass in hydrogen production will protect the environment. Because it uses CO2 during photosynthesis and doesn't add
to the carbon inventory when burned, biomass is considered a carbon neutral emitter. Biomass may be regarded as a negative carbon dioxide emitter if the CO2 generated during the gasification process is
captured and not released into the atmosphere. It has been demonstrated that solid-based sorbents, like CaO, have a high CO2 collection efficiency at high temperatures. For sustainable hydrogen production, steam gasification of biomass combined with carbon dioxide capture may therefore be a viable choice. Furthermore, the yield of hydrogen can be greatly boosted by combining the best possible factors that affect its generation.
