Descrizione del progetto
Ripensare l’elettrolisi dell’acqua
Le attuali tecnologie degli elettrolizzatori presentano limitazioni significative, il che ostacola la necessità di diffondere l’adozione dell’idrogeno come fonte di energia pulita. I metodi attuali devono fare i conti con inefficienze, dipendenza da materiali critici e preoccupazioni ambientali, quali quelle riguardanti le membrane fluorurate. Questi inconvenienti impediscono gli sviluppi intesi a garantire una produzione sostenibile di idrogeno e ostacolano la transizione verso un’economia più verde. In questo contesto, il progetto REDHy, finanziato dall’UE, propone una soluzione adattabile, ecologica ed efficiente dal punto di vista dei costi, che supera lo stato dell’arte della tecnologia. A differenza dei predecessori, REDHy non impiega materiali critici o membrane fluorurate, soddisfacendo gli obiettivi di sostenibilità fissati per il 2024; una pila a 5 celle prototipo mira a validarne l’efficienza. Grazie alle elevate densità di corrente e alle basse temperature, la soluzione promette prestazioni stabili, fondamentali per le future infrastrutture a idrogeno.
Obiettivo
The REDHy project tackles the limitations of contemporary electrolyser technologies by fundamentally reimagining water electrolysis, allowing it to surpass the drawbacks of state-of-the-art (SoA) electrolysers and become a pivotal technology in the hydrogen economy. The REDHy approach is highly adaptable, enduring, environmentally friendly, intrinsically secure, and cost-efficient, enabling the production of economically viable green hydrogen at considerably increased current densities compared to SoA electrolysers. The REDHy method is based on the findings of numerous EU-funded initiatives and patented by the DLR (TRL2). It is uniting academic and industrial entities across a broad spectrum of expertise. Unlike SoA electrolysers, REDHy is entirely free of critical raw materials and doesn't require fluorinated membranes or ionomers, while maintaining the potential to fulfil a substantial portion of the 2024 KPIs. In accordance with Europe's circular-economy action plan, a 5-cell stack with an active surface area exceeding 100 cm2 and a nominal power of 1.5 kW will be developed, capable of managing a vast dynamic range of operational capacities with economically viable and stable stack components. These endeavours will guarantee lasting and efficient performance at elevated current densities (1.5 A cm-2 at Ecell 1.8 V/cell) at low temperatures (60 °C) and suitable hydrogen output pressures (15 bar). The project's ultimate objective is to create a prototype, validate it in a laboratory setting for 1200 hours at a maximum degradation of 0.1%/1000 hours and achieve TRL4. This final phase will emphasize the potential of the REDHy approach and its crucial role in the upcoming hydrogen economy, secure subsequent investments, and showcase the necessity for ground-breaking, innovative thinking to reach climate objectives in a timely fashion.
