Technical Seminar Held in Greece

MHI-MME held a Mitsubishi Heavy Industries Group Technical Seminar in Athens Greece in November 2022.
To coincide with the MARTECMA (Marine Technical Managers Association) conference, we introduced MHI group-wide activities and initiatives across the value chain to decarbonize the maritime industry to more than 50 participants of Greek shipping companies.
The seminar's agenda is as follows:

(Greece seminar agenda)
・Overview of the Mitsubishi Heavy Industry Group
・Energy transition Project between MSB & MME “Project MaTis”
・Shipping, Marine Solutions (MSB)
・Marine Machinery, Onboard Energy & Environmental (MHI-MME)
・Technical Update of MET turbochargers

Although we have been conducting these seminar once every two years, this was the first seminar in three years due to COVID-19. Compared to the previous seminar, it was remarkable that all the companies showed a very high level of interest in decarbonization.

At the reception following the seminar, participants discussed technical challenges of decarbonization of the maritime industry from their own perspectives, which proved to be a very useful opportunity. We will try to propose future decarbonization solution responding to customer needs.
Since its founding in 1884, as a global leader in engineering and manufacturing, the MHI Group has been committed to addressing social issues and supporting people's daily lives. By incorporating cutting-edge knowledge into advanced technological capabilities accumulated over its long history, we are working to enrich people's lives through energy transition toward a carbon-neutral society, making social infrastructure smarter, and developing cyber-security fields.

MMMCZCS CEO Visits Carbon Neutral Park

In October 2022, Mr. Bo Cerup-Simonsen, CEO of MMMCZCS(*1) and Mr. Claus Winter Graugaard, Head of Onboard Vessel Solution, visited the MHI Head Office and the Carbon Neutral Park located at the Research & Innovation Center of MHI Nagasaki.
We introduced MHI's zero emission initiatives, including an ammonia combustion facility, a CO₂ capture facility, and a biomass gasification facility. We received enthusiastic questions from the viewpoint of marine applications, and the tour was attended with great interest.

Success Achieved in Next Generation Oilless Cryogenic RC Turbine Generator

MHI-MME has conducted a demonstration test using low-boiling point refrigerant to generate electricity by utilizing the cold energy generated when the cryogenic medium vaporizes. The test has shown the stability of the refrigerant cycle, and that the specified regenerative output can be achieved.
The demonstration test facility consists mainly of a Cryogenic Organic Rankine Cycle (ORC) turbine generator, refrigerant condenser (cryogenic medium vaporizer), refrigerant tank, refrigerant pump, and refrigerant evaporator, and was designed to simulate actual gas vaporization facilities (e.g., marine FGSS(*1) and land-based gasification facilities).
This demonstration test has yielded useful results that will lead to future product commercialization, such as understanding the phase change(*2) of cryogenic medium and refrigerant cycle characteristics, as well as confirming controllability.
The next-generation cryogenic ORC turbine generator developed solely by our utilizes MHI's proprietary turbine and cryogenic technologies. In addition to compactness and high performance, the fully-sealed hermetic casing does not leak refrigerant outside the system, and maintenance-free operation has been achieved through the use of oilless magnetic bearings.
We will continue to contribute to the low carbon and decarbonization of the maritime industry by developing various new technologies and further expanding its offerings, including products that contribute to improved engine efficiency, such as cold heat recovery systems for gas vaporization and engine exhaust heat recovery systems.
