MAN engines are H2-ready, i.e. prepared for operation with 100% hydrogen. Thanks to this hydrogen readiness, MAN gas engines can be adapted with conversion kits and made to run with hydrogen with comparatively little effort.
The switch to hydrogen is not only a technological advance, but also expands the possible applications of existing plants. By adapting existing plants, they can be prepared for operation with hydrogen and used accordingly.
A key advantage of H2 readiness for stationary gas engines is the flexibility and future-proofing of the plants. Operators can convert their existing natural gas plants to hydrogen with minimal effort and thus benefit from the properties of this energy carrier. This enables gradual adaptation to changing legislative requirements and market conditions.
The reliability and efficiency of MAN engines is also maintained in hydrogen operation. The targeted adaptation of components such as turbocharging, injectors and mixture preparation ensures that the engines also function optimally under the new operating conditions. This leads to high availability and low operating costs of the systems.
In addition, H2 readiness offers significant economics. Since no extensive structural changes to existing plants are required, operators can protect their investments while reaping the benefits of hydrogen operation. This makes the transition to hydrogen not only economically viable.
The MAN H3268 hydrogen engine is an eight-cylinder V-engine with a bore of 132 mm and a stroke of 157 mm. It is ideal as a stationary engine for combined heat and power generation and runs at a constant speed of 1,500 rpm at 50 Hz. The MAN H3268 is based on the tried-and-tested basic engine of the MAN E3268 combustion engine, which is already used in many thousands of natural gas and special gas engines. To make it fit for operation with hydrogen, turbocharging and mixture preparation have been adapted. During the development of the new hydrogen engine, care was taken to implement a similar geometry and identical connections to the current engine portfolio in order to ensure the H2 readiness of plants. This makes it much easier to convert existing plants from running on natural gas to hydrogen, as no major conversions have to be carried out.
The MAN H3268 also impresses with its high power density. It offers a similar performance class to the MAN E3268 natural gas engine, which delivers 370 kWmech Powered by green hydrogen, electricity and heat are produced in a 100% CO2-neutral manner and with high efficiencies. In the future, the H2 engine portfolio is designed for different performance levels, depending on individual requirements.
The entire portfolio of stationary MAN natural gas engines, which includes the E0834, E0836, E2876, E3268, E3262 and E3872 series, can be converted to hydrogen operation. Conversion is possible for both naturally aspirated and turbocharged engines.
Advantages of the conversion:
- Use of existing plants with hydrogen
- Retrofitting of existing infrastructure
- Extended application possibilities of the system
MAN Engines is using its many years of experience in the field of hydrogen technology to further develop solutions for mobile and stationary applications. This means that existing plants can be adapted for use with hydrogen and continue to be used.
