Life Cycle Assessment of a Chamotte–Nickel Oxygen Carrier: Environmental Hotspot Identification in Oxygen-Carrier Synthesis

Alejandra Balaguera Quintero, Luisa María Arboleda Ramírez, Sara Castaño Gil, Juan Diego Jaramillo Restrepo et autres

Oxygen carriers (OCs) are essential materials in chemical looping technologies for low-carbon hydrogen production; however, the environmental implications of their synthesis remain insufficiently explored. This study presents a gate-to-gate life cycle assessment (LCA) of a chamotte–nickel OC produced via wet impregnation, following …
