Absolute environmental sustainability assessment of hydrogen production from organic waste in Thailand

The increasing global demand for renewable energy sources necessitates exploring sustainable alternatives to traditional energy production methods. Hydrogen, recognized for its clean-combustion properties and versatility, presents a promising solution for meeting global decarbonization goals. This study focuses on the potential of hydrogen production from organic waste in Thailand, a country with significant agricultural residues, municipal solid waste (MSW), and livestock manure. The research aims to quantify the hydrogen production potential from these waste streams and evaluate its environmental sustainability using the Absolute Environmental Sustainability Assessment (AESA) approach, grounded in the Planetary Boundaries framework. By applying Life Cycle Assessment (LCA) and comparing the environmental impacts of different technological pathways, the study will identify the most environmentally viable options for hydrogen production in Thailand. The findings will provide valuable insights for policymakers and industry stakeholders to guide decision-making, ensuring that hydrogen production aligns with Thailand's commitment to achieving Sustainable Development Goals (SDGs) while staying within planetary ecological limits. The results will also offer recommendations on integrating bio-hydrogen into Thailand’s energy sector, contributing to a global blueprint for sustainable energy transitions.
