Pressurized Efficient Alkaline EleCtrolysEr (PEACE)

Descrizione del progetto

Progressi nell’elettrolisi alcalina per aumentare la produzione di idrogeno

L’elettrolisi alcalina è una tecnologia economica e scalabile per la produzione di idrogeno verde. Il progetto PEACE, finanziato dall’UE, si propone di migliorare la sua efficienza e di ridurre ulteriormente i costi sviluppando un sistema ad alta pressione in grado di operare fino a 90 bar. PEACE userà un approccio innovativo di pressurizzazione a due stadi che prevede la combinazione di pressione idraulica e funzionamento in stack. In questo modo, il sistema eliminerà la necessità di compressori di idrogeno costosi, riducendo nettamente i costi di capitale e di esercizio. Questo dimostratore da 50 kW integrerà componenti avanzati per raggiungere un’efficienza del 70 % a 1 A/cm2. PEACE si propone di trasformare la tecnologia di elettrolisi alcalina, posizionando l’Europa come leader nei sistemi di idrogeno verde ad alta pressione entro tre anni.

Obiettivo

Among the different electrolysis technologies, AEL is very competitive, because of its low investment costs and good scalability. The levelized cost of hydrogen (LCOH) produced by AEL can be reduced by enhancing the efficiency, maximal current densities and by enabling better integration with downstream processes. A well-tuned design of high-pressure stack and system improve the performance and overall efficiency, by eliminating the need for further compression for downstream processes. As compressors for hydrogen represent a significant share of CAPEX and OPEX of electrolysis systems, those can be reduced or eliminated. In this project, the consortium will design and develop an AEL system demonstrator >50 kW, capable of operating at a pressure up to 90 bar, achieved by a novel concept in which the pressurization is done at two stages: by applying up to 60 bar hydraulic pressure using a pressure vessel in which a stack operates at additional 30 bar, resulting in up to 90 bar gas pressure. Integrating advanced components, innovative design, and optimizing operation strategies, through modelling and experimental testing, a system with an efficiency of 70 % (LHV) at a current density of 1 A/cm2 will be demonstrated. With this technology an AEL system will be provided that may lead to major cost reduction of green hydrogen production. The main scientific aims of the project are further supported by sustainability and circularity aspects as well as dedicated outreach activities, and jointly addressed by 2 medium-sized enterprise (SMEs), 4 R&D centres with established expertise in alkaline stack, system and Life Cycle Assessment (LCA), and one of the largest hydrogen production and utilization companies in the world. Lastly, use cases and the concept of the integrated plant will be proposed. Together, the new developments will target a technology breakthrough with a clear commercial perspective, placing Europe at the lead of highly pressurized AEL technology in 3 years.
