MAN Energy Solutions SE (Societas Europaea) is a German manufacturer of large diesel engines and turbomachinery for maritime and stationary applications based in Augsburg.

[4][5][6] Additionally, it produces ship engines that run on synthetic fuels[7] and develops technologies for carbon capture and storage (CCS), large heat pumps, and electrolysers.

[8][failed verification] The company employs around 15,000 people at more than 140 international locations, particularly in Germany, Denmark, France, Switzerland, the Czech Republic, India, and China.

Sander'sche Maschinenfabrik was established in Augsburg in 1840, also underwent multiple mergers and transformations, and was merged with Maschinenbau-Actien-Gesellschaft Nürnberg (formerly Eisengießerei Klett & Comp.)

[13] In 1921, Gutehoffnungshütte acquired a majority stake in MAN, creating a conglomerate that encompassed traditional ironworks, modern mechanical engineering, and the production of various commercial vehicles.

Production primarily included tanks, diesel engines for submarines, and shell casings in support of the Nazi war effort.

[17][18] In addition, the Volkswagen Group acquired the majority of the share capital and voting rights of MAN SE in 2011.

[29] They also introduced a hydrogen option for gas-powered engines and collaborated with Elbdeich to launch the Elbblue container ship using synthetic methane.

As a result, MAN Energy Solutions announced plans to provide ammonia propulsion for maritime operations by 2026.

[34] In the same year, MAN Energy Solutions equipped 19 container vessels of A. P. Møller-Mærsk shipping company with methanol engines.

[36][24] Other business areas of the company encompass the production and distribution of gas and steam turbines, power plant technology, and reactors for the chemical industry.

[37][38] MAN Energy Solutions is also working on the development of a marine engine based on the combustion of climate-neutral fuels such as methanol or ammonia.

Low-speed diesel engines do not require a transmission system because they are directly connected to the propellers by drive shafts.

[42] MAN Energy Solutions also offers medium-speed four-stroke engines[43] that can be operated using liquid or gaseous fuel.

Medium-speed engines[44] are deployed to propel all types of merchant vessels, but are also used in passenger ships due to their compact nature and their amenability to flexible mounting.

As well as cruise liners, other areas of use for medium-speed engines include specialist vessels such as tugs, dredgers or cable-laying ships.

[45][46][47] MAN Energy Solutions builds exhaust-gas turbochargers[48] using single-stage radial and axial turbines to create high charging pressures.

[53] For industrial processes, including the production of fertilizers, iron and steel, as well as for petrochemical-manufacturing applications, MAN Energy Solutions develops and produces a variety of compressors,[54] as well as steam and gas turbines for power generation.
