The 100 kW model is the primary configuration for commercial vessel installations. It ships with 430 kWh of integrated battery storage as standard and is scalable from four to eight or more units per vessel depending on deck layout. It is the basis for all reference fuel savings calculations.
Specifications
System architecture
Power routes directly from the DC generator through a DC/DC converter to the 430 kWh battery storage system. No grid synchronisation is required -- the system is self-contained and compatible with the vessel's existing DC bus without modification.
Generation begins at 2 m/s and continues through all wind conditions. The 430 kWh storage capacity comfortably handles the generation and load profile of a 100 kW turbine across a full operating day, absorbing generation peaks and supplying vessel loads at a stable voltage.
Multiple units share a common battery management architecture. In a four-unit configuration the total integrated storage is 1,720 kWh; in an eight-unit configuration it is 3,440 kWh -- sufficient for meaningful overnight supply of vessel hotel loads.
Fuel savings
4 × 100 kW reference configuration
Average output across 6,500 operating hours per year, after wake and shadow reduction.
Annual electricity production.
Diesel saved per year at 0.295 kg/kWh.
Annual fuel cost saving at USD 700--1,000 per tonne. Direct generation only.
Indicative payback period under typical operating conditions and prevailing fuel costs.
8 × 100 kW extended configuration
Average output across 6,500 operating hours per year.
Annual electricity production.
Diesel saved per year.
Annual fuel cost saving at USD 700--1,000 per tonne. Direct generation only.
A 10--30% wake and shadow reduction is applied for conservative multi-turbine layouts. Aerodynamic drag reduction adds further savings not included above.
Deck layout
In the four-unit reference configuration, turbines are mounted at the primary generation positions identified through vessel-specific deck layout assessment -- typically at or near the superstructure leading edges where the venturi effect is strongest and wake interactions between units are minimised.
The eight-unit configuration extends coverage to secondary deck positions, capturing venturi benefit across a larger proportion of the vessel's aerodynamic envelope. This configuration is specified where deck geometry allows deployment without interference to cargo operations, navigation equipment, or safety clearances.
Deck layout optimisation is conducted as part of every installation assessment. H Nordic provides a preliminary layout recommendation based on vessel class documentation; final positioning is confirmed following a vessel survey.
Scalability
The electrical architecture of a four-unit installation is designed for expansion. Additional units connect to the existing DC bus and battery management system without requiring modification to the base installation. This means operators can begin with a four-unit configuration, validate performance on their specific route, and expand to eight units based on observed results.
The incremental capital cost of the four additional units in an expansion scenario is lower than an eight-unit greenfield installation, and the existing installation provides real performance data for the business case.
