MAN Energy Solutions has signed a cooperation agreement with clean technology company Orcan Energy covering technologies for waste heat recovery.

Orcan Energy offers an energy-efficient solution, with the help of which waste heat from the engine can be used to simultaneously increase efficiency and reduce emissions. The efficiency PACK technology will be available to MAN Energy Solutions' marine and power plant customers for retrofitting their engines.

Orcan Energy's energy-efficient solutions are based on Organic Rankine Cycle (ORC) technology. Orcan Energy has repurposed this technology, until now used primarily in large-scale systems, for use in the modular product sector. The technology works in a similar way to steam power plants but by using organic media, which evaporate at lower temperatures than water, the waste heat can also be used at comparatively low temperatures of 60°C and above. This allows engine exhaust gases, as well as steam, thermal oil and cooling water, to contribute to reducing CO2 emissions simply and efficiently.

“We have made it our mission to reduce harmful emissions,” said Dr. Uwe Lauber, CEO of MAN Energy Solutions, commenting on the new collaboration. “This also means that we are offering our customers the most advanced technologies for optimizing the efficiency and environmental friendliness of their systems.”

“Orcan Energy is a real expert in utilising waste heat, and has established a high-performance product line on the market that we are making available to our customers,” said Dr. Thomas Spindler, Head of Upgrades & Retrofits at MAN Energy Solutions. “This allows them to increase the efficiency of their MAN engines with leading technology for utilising waste heat.”

When equipped with an Orcan Energy efficiency PACK, the efficiency of a MAN 18V48/60 engine, for example, can be increased by almost 4%, thereby giving typical savings of 1,220 tonnes of fuel and 3,830 tonnes of CO2 per year.

“MAN Energy Solutions is a global player with a large network of customers. We have the same high quality requirements and serve the same target group. We are, therefore, happy that we can now put our products on the market even faster thanks to this new sales channel and boost the use of energy-efficient solutions worldwide,” explained Dr. Andreas Sichert, CEO of Orcan Energy AG.
