Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050.

Highly efficient and stable Ru-free catalyst for hydrogen generation from ammonia

Green Car Congress

Although the thermocatalytic ammonia decomposition reaction (ADR) is an effective way to obtain clean hydrogen, it relies on the use of expensive and rare ruthenium (Ru)-based catalysts, making it not sustainable or economically feasible. A complete ammonia conversion to hydrogen was achieved at an economically feasible 450 ?C
