Cost comparison between lithium batteries, fuel cells, reversible solid oxide cells as storage for off-grid rooftop PV

Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modeling assumed a typical commercial building in Los Angeles.Researchers from Khalifa University in the United Arab Emirates have conducted a techno-economic analysis of a building energy system based on standalone rooftop PV linked to either lithium-ion batteries, proton-exchange membranes reversible fuel cells (PEM RFC), or reversible solid oxide cells (RSOC). They have found that each of the proposed configurations ...
