Sustainable Production of Porous Silicon from Silica and End-of-Life PV Silicon via Magnesiothermic Reduction for Hydrogen Liberation in a Trickle Bed Reactor

Hydrogen is a promising clean energy carrier, but safe and practical storage remains a major challenge. This thesis develops a sustainable approach as a means to store and liberate hydrogen from silicon-based materials (synthesise and valorise routes). Modification on these materials couple with reactor integration improve their hydrogen liberation for in-situ applications. This work demonstrates a practical pathway for safer hydrogen storage and utilisation while supporting renewable energy recycling and circular resource use.
