Danfoss è in prima linea nello sviluppo di tecnologie innovative e sostenibili per la generazione e la distribuzione dell'energia e per aumentare l'efficienza nel consumo energetico. Future Trends in Power Supply Units for Hydrogen Electrolyzers

Companies should consider the total cost of owning an electrolyzer

What you should consider for Levelised Cost of Hydrogen :
- OPEX
- CAPEX
- Efficiency

EFFICIENCY
(most important parameter - apart from the electricity cost)
- DC quality (Low ripple values, important for electrolyzer)
- AC quality (Low THD, less current in transformer and cables)
-Part-load operation

GRID CONNECTION
(important for the future smart electrical grid)
- Grid code compliance (de-risk project)
- Total Harmonic Distortion (no extra filters)
- Reactive power (decreased need to install new grid, voltage control)

INSTALLATION COST & TIME
(How the converter influences cost-drivers for the site)
- Compact converter leaves small footprint (no external filters)
- Modular design (ease of quick installation)
- Liquid cooling (revenue stream for district heating)
- Back-channel cooling (low cost, no air conditioning)

UPTIME & AVAILABILITY ?
- Quality
- Robust
- Environment

MAINTENANCE
- Spare parts
- Excludes one unit
- Easy replacement
