full scale multi-fuel & multi-MW test-center for energy solutions

Strengthen energy resilience, efficiency and operational flexibility

Energy House provides testing, validation and demonstration services for energy systems and components relevant to naval, off-grid and defence applications. The facility enables developers, suppliers and system integrators to test technologies individually or as part of integrated energy systems under controlled, realistic operating conditions.

The infrastructure supports testing across the energy chain, including fuel handling and bunkering, power generation units, power electronics, battery and hybrid systems, exhaust and emission systems, electric motors and energy management systems.

A key capability is the ability to combine different technologies, energy carriers and loads in one test environment. This makes Energy House particularly relevant for defence applications where energy resilience, redundancy, fuel flexibility and efficient use of available energy are critical. Technologies can be validated before deployment, reducing technical risk and accelerating integration into vessels, mobile systems, bases and other off-grid installations.

Services and capabilities

Energy House can support:

• Fuel handling and bunkering: Testing infrastructure and components associated with alternative fuels, including ammonia and hydrogen.

• Power generation units: Testing generators, fuel cells and other power-generation technologies, including operation with alternative and mixed fuels.

• Power electronics and electrical systems: Validation of high-voltage equipment, converters, charging systems and interfaces between generation, storage and loads.

• Battery and hybrid systems: Testing batteries as individual systems or integrated with generation and power-management technologies.

• Engines and fuel flexibility: Testing combustion engines and generator sets with different fuels and fuel combinations to evaluate performance, emissions and operational behaviour.

• Exhaust and emission systems: Integration and testing of technologies associated with exhaust treatment and emissions reduction.

• Integrated energy systems: Combining generation, storage, distribution and control technologies to validate complete energy architectures rather than individual components alone.

• Energy management and efficiency: Testing control strategies that optimize available generation, storage and loads—particularly relevant for constrained or off-grid energy systems.

Examples from previous projects

Test Driving of Arja
A Wärtsilä 3.5 MVA generator set was tested with ammonia, natural gas, biogas and mixed fuels. The work focused on fuel flexibility, dynamic performance, emissions and safety. For defence applications, this type of testing demonstrates how power-generation assets can be validated for greater fuel flexibility and reduced dependence on a single energy carrier.

Sea Zero
Full-scale battery short-circuit and safety testing was performed in support of Hurtigruten's development of emission-free vessels. Testing included thermal-runaway behaviour and design evaluation. These capabilities are relevant when validating safe, resilient battery and hybrid power systems for naval vessels and off-grid installations.

Amogy – NH₃ Cracker
A full-scale ammonia-cracking powerpack integrated with a PEM fuel cell was tested at Energy House. The project demonstrated how fuel processing and power-generation technologies can be combined and validated as an integrated system—relevant to future distributed and fuel-flexible power solutions.

From component to integrated system

The value of Energy House is not limited to testing whether an individual component works. We can help determine how components perform together as an energy system: from fuel entering the system, through conversion and electrical distribution, to propulsion or other loads, energy storage and exhaust handling.

For defence and naval customers, this provides an environment for de-risking new energy technologies, improving system efficiency, increasing operational flexibility and strengthening energy resilience before deployment in mission-critical applications.
