A novel stand-alone microgrid concept incorporating green ammonia for energy storage is proposed in this work. Wind and solar energy are captured and used for meeting residential demands or powering water electrolysis. Hydrogen produced from electrolysis is further used to produce ammonia through the Haber–Bosch process.
READ MOREAbstract. Microgrids are self-sufficient energy ecosystems designed to tackle the energy challenges of the 21st century. A microgrid is a controllable local energy grid that serves a discrete geographic footprint such as a college campus, hospital complex, business center, or neighborhood.
