Biomass-Based Hydrogen Extraction and Accompanying Hazards-Review

Area of Science:

• Energy science and sustainable technology.
• Biomass conversion and green chemistry.

Background:

• Growing global energy demand necessitates alternatives to fossil fuels.
• Reducing carbon dioxide emissions is a key environmental challenge.
• Hydrogen (H2) offers a promising green energy solution.

Purpose of the Study:

• To review methods for hydrogen (H2) separation from biomass.
• To analyze both biological and thermochemical conversion processes.
• To identify and discuss potential hazards associated with these methods.

Main Methods:

• Literature review of biological hydrogen production.
• Literature review of thermochemical (TC) hydrogen production from biomass.
• Analysis of safety and environmental considerations for each method.

Main Results:

• Biological methods offer sustainable H2 production pathways.
• Thermochemical (TC) processes provide alternative routes for H2 extraction.
• Both approaches present specific operational and safety challenges.

Conclusions:

• Hydrogen (H2) derived from biomass is a viable green energy option.
• Careful consideration of method-specific hazards is essential for safe implementation.
• Further research can optimize H2 separation efficiency and safety.
