Conversione elettrica di potenza negli elettrolizzatori e fuel cell
Energy efficiency in hydrogen electrolysis
Dario Rudellin - Danfoss
Sommario
(in lingua inglese)
- Electrolysis - a key element in electrification
- Hydrogen Electrolysis Powered by Danfoss
- H2 Production cost
- Electrolyzer plant with SCR + STATCOM
- Electrolyzer plant with Danfoss Grid Converter
- Energy Flow Diagram
- Danfoss AC to DC converters for Electrolysis
- Everfuel HySynergy Power to X plant
- Grid simulations of 1 GW Electrolyzer plant with Danfoss Grid Converter
- Typical Grid Balancing services acquired by the TSO
H2 Production cost
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
- Robustness
- Environment
Maintenance
- Spare parts
- Easy replacement
Attached, you can download the full pdf of the presentation.
