Solutions – Applications

Marine

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 or 200 kW of net power per module. This not only reduces your vessel’s fuel consumption and carbon emissions, but significantly improves EEDI or EEXI and CII indexes as well. Payback time is two to four years for cash-out investments, for commonly used fuels today. For tomorrows upcoming future fuels with lower energy densities, in combination with a CO2 levy, this return on investment can be even more attractive. For financed asset investments, typically a positive accumulated free cashflow is reached from the first day of operation.

Proven reliability

Efficiency PACKs have been sold to customers worldwide with a proven reliability in over 3.9 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 negligible scheduled maintenance required. The first scheduled TBO [Time Between Overhaul] is 120.000 operational hours. The modules are built extremely compact, which means they are easy to install and require only 1.5 m² (100 kW) or 3.9 m² (200 kW) of engine room floor space. Thanks to its excellent part load capacity and modular design, it adapts quickly to the heat source to maximize power output, which may reach up to 1 MW of net electrical power into a stack configuration.

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.

 

Products

Efficient, flexible and cost effective. Our patented efficiency PACKs let you generate your own zero-carbon electricity from the unused energy produced by your combustion engines (exhaust gas, jacket cooling water, saturated steam or thermal oil). Featuring a lean circulation structure, standardized and proven industrial components, and intelligent control algorithms, including automatic & easy synchronizing to the ship's grid, without the use of a frequency drive, they ensure that the waste heat generated in your processes is harnessed efficiently. Wherever you are in the world.

We offer attractive second-generation ORC solutions tailored to your precise requirements.

Technology

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:
