Progetto TEZIO – Tecnologia Energetica a Zero ImpattO ITA (English below) Nell’ambito finanziamenti della Fondazione Cassa di Risparmio di Perugia inerenti a “Sostenibilità ambientale ed economia circolare”, è risultato vincitore il progetto TEZIO (2018.0518.026 RICERCA SCIENTIFICA E TECNOLOGICA). Il progetto TEZIO (Tecnologia Energetica a Zero ImpattO) si colloca in contesto di produzione energetica di piccola taglia e mira allo studio pre-prototipale di un sistema di conversione energetica avanzata (basato su celle a combustibile) per la valorizzazione di materia residuale (esempio: rifiuti agro-zootecnici, scarti organici di processo). I risultati attesi ambiscono a produrre valore su più livelli, da questioni di respiro globale ad impatti strettamente territoriali. Infatti, il fulcro del progetto è l’idea di sostenibilità energetica e

Airflow Management in Solid Oxide Electrolyzer

FcLab/ Febbraio 8, 2018/ electrolysis, fuel cells, papers, SOE, SOFC, storage, systems/ 0 comments

Hydrogen is being studied as a means of energy storage and can be synthetized to store renewable energy and successively used as a fuel for power production or transport purposes. High temperature solid oxide electrolyzers (SOE) are proposed as a technology to produce hydrogen with high energy efficiency and high power density. Within the studies on SOE operation, little attention has been given to the oxygen electrode side, where air is normally used as a sweep gas. In this study, we consider the option of reducing the air flow rate when operating an SOE stack. The advantages in terms of efficiency are calculated, showing that efficiency increases up to 2.8% when reducing the air flow rate

Upgrading vs reforming for biogas-to-electricity in SOFC

Arianna Baldinelli/ Gennaio 24, 2018/ fuel cells, fuels, news, papers, SOFC, systems/ 0 comments

Aiming at designing biogas-to-electricity advanced systems, Solid Oxide Fuel Cells are promising candidates. They benefit from scalability on plant sizes that suit anaerobic digesters potentialities. For biogas-Solid Oxide Fuel Cells applications, the implementation of an external pre-reformer is usually considered. However, the possibility to perform direct fuel feeding to the Solid Oxide Fuel Cell offers new opportunities towards the realization of lean systems, which are competitive especially on small-scale installations (i.e. on-farm biogas-to-electricity conversion). In this frame, scientific literature is rather poor and, to cover this gap, system simulations are called for two reasons: first, to demonstrate the potential efficiency gain of new concepts; second, to provide a meaningful support for long-term experimental investigation on Solid
