Explanation

Biomass gasification is a process that converts organic materials like wood, agricultural residues, or waste into a combustible gas mixture known as synthesis gas or syngas. The resulting syngas can be used as a fuel for various applications, including electricity generation, heating, and as a feedstock for the production of biofuels and chemicals.

Coconut shells, groundnut shells, and rice husk are examples of biomass that can be used in biomass gasification.

The combustible gases generated from biomass gasification do not consist of hydrogen and carbon dioxide only. They also include other gases such as methane and carbon monoxide.

The combustible gases generated from biomass gasification can be used for direct heat generation and also in internal combustion engines.

Therefore, only statement 1 is correct.
