Hydrogen-based electricity storage optimization on buildings by coupling thermal and photovoltaic electricity production towards carbon neutrality

Abstract Self-sufficiency (SS) of buildings with low greenhouse gas (GHG) emissions can be obtained using photovoltaics (PV). To maximize self-consumption - minimizing the import grid electricity PV coupled a hydrogen storage system converting to by electrolysis during summer season, when on-site production is higher, and it winter season fuel cells. This article deals sizing constraints solar systems at building-scale. The future building for Smart Living Lab (SLL) in Fribourg (Switzerland) has been taken as case study. It four stories mixed usage (Office-building Research facilities), multi-oriented installation order produce enough achieve least 50% self-sufficiency. Using production, this study aims optimise allowing reach required self-sufficiency ratio. Finally, comparison global efficiency three different demand-side scenarios.
