Abstract
Hydrogen can manage intermittent Renewable Energy Sources (RES), especially in high-RES share systems. The energy transition calls for mature, low cost, low space solutions bringing the attention to unitized items such as the reversible Solid Oxide Cell (rSOC). This device, made of a single unit, can work as an electrolyzer and as fuel cell with high efficiency, fuel flexibility and producing combined heat. The objective of this review is to identify and classify rSOC applications to the building sector as an effective solution and to show how much this technology is near to its commercialisation. Research & Development projects were analysed and discussed for a comprehensive overview. Conclusions show an increasing interest in the reversible technology, although it is still at pre industrialisation stage with few real applications in the building sector, of which, the majority is reported, commented, and compared in this paper for the first time.
