Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Optimal Lithium‐Ion Battery—Supercapacitor Energy Storage System Capacity for Off‐Grid Intermittent Renewable Energy Mini‐Grids

Energy Science &Engineering, EarlyView.
Deployment of an aging‐based controller during designing of optimal lithium‐ion battery—supercapacitor (LB‐Sc) hybrid energy storage system (HESS) capacity, in off‐grid IREMGs, improves performance of the LB and reduces its aging rate. Also, annualised cost of the LB‐Sc HESS improves by 33.15% in relation to optimal LB SESS.
