Adjustable Configuration based on Site Status

Capacity adjustment is much flexible

Saving operation cost by optimal configuration

Enhance utilization factor of whole system

Hydrogen-based config • Secure power grid stability from VRE volatility • Long time(for Weekly~ Seasonal) Energy Storage

*PCS: Power Conversion System(AC/DC or DC/DC)

• Derive to Maximum green hydrogen production • Clean energy carrier for transportation & industry

* Buffer: Electric power storage such as battery 15
