Module Description
This module provides a concise introduction to hydrogen as an alternative fuel and its role in sustainable energy systems. It explains the classification of hydrogen into green, blue, and gray, and outlines the main production routes for green and gray hydrogen. Special emphasis is placed on blue hydrogen, as it represents an important transitional step toward green hydrogen, focusing on high-temperature catalytic processes that produce hydrogen and syngas while limiting direct CO₂ emissions. Methane cracking and dry reforming of methane are examined in detail, with representative experimental results analyzed and discussed. Furthermore, chemical looping is introduced as an advanced pathway for blue hydrogen production, enabling hydrocarbon conversion through oxygen carrier mediated redox reactions.
Learning Outcomes
By the end of this module, participants will be able to:
- Investigate hydrogen as an alternative fuel and energy carrier, including its production methods, applications, and ongoing research across different regions.
- Explore blue hydrogen production, and evaluate ways to improve efficiency, carbon utilization, and process integration as a transitional path to net-zero emissions.
