Solutions – Applications


With many years of experience, we have specifically developed an efficiency PACK for the marine industry. The design is adapted to the typical requirements on board of vessels: the efficiency PACK is compact and robust in order to save space and withstand the strong vibrations and shock loads at sea. The components used to build the efficiency PACK are specifically selected to cope with the high ambient temperatures in engine rooms.




Save costs

Our ORC modules convert waste heat from exhaust gases, cooling water, steam or thermal oil into clean electricity, with up to 100 kW of net power per module. This reduces your vessel’s fuel consumption and carbon emissions. Payback time is two to four years.

Proven reliability

Efficiency PACKs have been sold to customers worldwide with a proven reliability in over 2.8 Mio. hours of operation. Its specific marine design and standardized components ensure a robust and reliable operation under all marine conditions.

Flexible and low-maintenance

The efficiency PACKs operate entirely independently and automatically with little maintenance required. The module is easy to install and requires only 1.5 m² of floor space. Thanks to its excellent part load capacity and modular design, it adapts quickly to the heat source to maximize power output.


Geothermal plant Kirchweidach

From industry to geothermal energy: Orcan Energy has implemented the first large-scale geothermal project in Kirchweidach. Six efficiency PACKs convert the excess heat from the geothermal plant into electricity in a highly effective manner, saving 4,000 tons of CO2 annually. Even in the complex environment of the geothermal plant, the modules deliver CO2-free electricity economically and with base-load capability. Installation and commissioning were very simple and fast thanks to delivery in containers. In a very short time, it was possible to fully exploit the energy potential of deep heat.

Rederij Doeksen

Optimized energy recycling on board: The high-efficiency catamarans "MS Willem Barentsz" and "MS Willem de Vlamingh" of the Dutch shipping company Doeksen combine particularly environmentally friendly technologies and materials for the first time to make ship operation in the nature-protected Wadden Sea as sustainable as possible. The waste heat is utilized on board with the help of an eP 050.100 efficiency PACK from Orcan Energy. The result of the waste heat utilization: a total saving of 318 tons of CO2, 260,000 liters of fuel and 462,600 kilowatt hours of electricity per year.

Engine Power Plant (South East Asia)

CSBC-DEME Wind Engineering

Eight efficiency PACKs will be installed aboard Taiwan's first offshore installation vessel, Green Jade. This will make Orcan Energy part of a massive wind farm project in Asia. The four dual-fuel engines installed will each be equipped with two efficiency PACKs. When all engines are running, the modules generate more than 500 kilowatts of electrical energy from the waste heat on board, thus providing an important building block for the decarbonization of the ship.

OC 300.800

With our ORCAN cooler we offer a complete new category of cooling solutions for engines and industrial processes. As the only dry-cooler in the world, it does not require any external power, so you can significantly optimize your company`s energy-intensive cooling processes. The ORCAN cooler can be used for cooling temperatures above 65 degrees Celsius, its power range starts at 300 kW thermal and reaches up to several MW.


Inside the efficiency PACK, an ORC-Cycle is running: The evaporator transfers the heat into the efficiency PACK. Thereby, the pressurized working fluid is heated and then routed to the expansion machine. The vaporized working fluid drives the expansion machine and thereby also the generator producing electricity. The working fluid is condensed in the condenser, which releases residual heat into the ambient air. The now again liquid working fluid is brought to high pressure in the pump. This closes the cycle and it starts again.

Simple Integration

Due to the plug and play approach and the flexibility of the modules, they can be easily integrated on the ship, for example on existing steam or thermal oil circuits or directly into the exhaust gas:
