Idrogeno

L’idrogeno verde riveste un ruolo centrale nella transizione energetica e nella decarbonizzazione dell’economia. Le capacità degli elettrolizzatori, ossia dei dispositivi che generano idrogeno da corrente ottenuta in modo rigenerativo, sono in costante crescita. I sistemi a celle a combustibile per la conversione dell’idrogeno in energia efficiente e pulita utilizzano un processo inverso rispetto a quello degli elettrolizzatori, ma sono composti - come gli elettrolizzatori - da singole celle e stack, che vengono collegate a formare stringhe ad alta tensione.

Monitoraggio ad alta tensione e misurazione della corrente

Per riconoscere tempestivamente difetti e fenomeni di usura delle celle elettrolitiche o a combustibile è necessaria una misurazione continua e precisa delle tensioni di stack e stringa fino a 1500 V. A seconda del metodo elettrolitico di volta in volta in uso può rendersi necessario il monitoraggio di correnti elevate, nell’intervallo compreso tra centinaia e migliaia di Ampere, e delle temperature all’interno degli impianti.

Perché Knick?
Grazie all’isolamento e all’affidabilità elevati, i trasmettitori ad alta tensione e gli amplificatori di isolamento Knick stanno già dimostrando la loro validità in numerose applicazioni con l’idrogeno. Dato che gli elettrolizzatori spesso vengono fatti funzionare in luoghi decentrati, la disponibilità dell’impianto dipende fortemente dall’affidabilità e dall’assenza di manutenzione del sistema di misura. Questi requisiti vengono soddisfatti in modo esemplare dai nostri convertitori di tensione, di corrente e di temperatura.
