## Hybrid Propulsion System Assessment
Detailed analysis of operational strategy, environmental impact, and economic viability for maritime vessels.

## Propulsion Architecture
* **Shore Power:** Used for docking and charging.
* **Battery Storage:** Buffer for low-power maneuvers and peak shaving.
* **Diesel Engines:** High power for active transit.

## Operational Performance
* **Pure Electric Mode:** Effective for maneuvers under 20 kW; utilized during 71.1% of trials (74.7 hours total).
* **Fuel Savings:** 87.47 kg of fuel saved, representing a 28.6% reduction rate.
* **Emissions:** Net CO2 reduction of 27.63%, highly dependent on grid carbon intensity.

## Energy Dynamics
* **Average Power:** 5.7 kW in electric mode vs 37.8 kW in diesel mode.
* **Energy Contribution:** Battery system handled 27% of total propulsion energy.

## Economic Analysis (CAPEX)
* **Investment Range:** €26,500 – €53,500.
* **Cost Breakdown:** Architecture & Integration (€25k), Motor & Controller (€12.5k), Shore Power Infrastructure (€2.5k).

## Strategic Comparison & Conclusion
* **Hybrid vs. Biodiesel (B100):** While the hybrid system offers ~28% CO2 reduction with high CAPEX, Biodiesel (B100) offers 74–90% reduction with zero capital investment.
* **Verdict:** The hybrid solution is rejected for inland waterway operators due to high upfront costs and operational complexity compared to drop-in biodiesel solutions.
