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. May 18, 2022 Emiliano BelliniResearchers 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 could result in low capital costs and high efficiency.The scientists quantified the impact of the PEM RFC and RSOC on overall system degradation. Their modeling considered a typical medium-sized commercial building in Los Angeles, California. Its minimum value of…
