MAN Engine programme for Hydrogen

STATIONARY ENGINES FOR HYDROGEN OR HYDROGEN ADMIXTURE UP TO 20 PERCENT BY VOLUME

Overview of the engine portfolio and applications

Hydrogen is a clean and renewable energy carrier that can be obtained by splitting water into its components hydrogen and oxygen. Hydrogen can be used as a fuel for various applications, including internal combustion engines. These engines use the hydrogen as a fuel to mix it with air and burn it. The only exhaust gas produced is water vapor that does not pollute the environment. Combustion engines with hydrogen can therefore be an environmentally friendly alternative to conventional engines with fossil fuels.

MAN Engines is using its many years of experience in the development of gas engines to qualify a large proportion of its engine range for use with up to 20 percent hydrogen admixture. This requires an adjustment of the engine settings to ensure efficiency and combustion stability. The addition of hydrogen offers the possibility of using surplus energy from wind turbines or solar plants in the form of renewable hydrogen, which benefits the energy transition. Hydrogen blending in gas engines means blending hydrogen with natural gas or biogas to improve combustion and reduce CO2 emissions.

HYDROGEN READINESS

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 a significant contribution to a sustainable energy supply. By adapting existing plants to burn hydrogen, emissions are drastically reduced, reducing the environmental footprint.

A major advantage of H2 readiness in stationary gas engines is the flexibility and future-proofing of the systems. Operators can convert their existing natural gas plants to hydrogen with minimal effort, thus reaping the benefits of this clean energy source. This allows for 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 continue to function optimally under the new operating conditions. This leads to high availability and low operating costs of the plants.

In addition, the H2 readiness offers significant cost-effectiveness. By not requiring extensive structural changes to existing facilities, operators can protect their investments while reaping the benefits of hydrogen operations. This makes the switch to hydrogen not only ecologically sensible, but also economically.

MAN ENGINES PURELY FOR HYDROGEN

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.

MAN Engines plays an important role in this process and is supplying 80 MAN E3262 gas engines. The 12-cylinder engines are installed in gensets from the Dutch partner MAN Rollo. In combination with electric motors, each two of the gas engines, which deliver a total of 990 kW, form the hybrid drive of the low-emission tankers.

MAN Engines solutions for EGA

In order to comply with the most important global directives, MAN Engines offers its customers numerous and flexible solutions for reducing emissions. From exhaust gas recirculation to diesel particulate filters and SCR systems, MAN Engines and its partners have a wide range of options for exhaust gas aftertreatment.

Hydraulic valve clearance adjustment

MAN is developing a maintenance-free valve train for industrial engines and is relying on the use of hydraulic valve clearance adjustment. A maintenance-free valve train eliminates the need to check and adjust the valve clearance. Additional customer benefits arise from the elimination of disassembly and maintenance activities, as well as flexible use of the installation space above the cylinder head.

MAN’s 9-litre diesel engine for off-highway applications put to the test in an agricultural tractor. For this usage, the SCR-only combustion and exhaust gas aftertreatment have been completely revised and adapted. During testing, a large number of field cycles were analysed and the test programme was modified for the tough use in the tractor.

MAN base engine: The basis for our engines

Engines are used in a broad range of applications. And each application places very different specific demands on the motor. The MAN-developed V-engine series D2868/D2862 has successfully managed to introduce 8- and 12-cylinder engines to the market in road vehicles, agricultural machinery, trains, yachts, workboats and for power generation as diesel and gas gensets.

Depending on the application, each engine technology has its advantages. Whether the focus is on electricity production or the primary use of heat, MAN Engines has the appropriate solution for higher efficiency.

Milestones of agricultural technology

As a manufacturer and developer of diesel engines, MAN has been closely associated with agricultural engineering since the early 1920s. The innovative engines were initially installed in the company’s own machines – from motorised ploughs to the company’s tractors – but were later increasingly sold to other manufacturers. Today, MAN engines can be found in agricultural machinery from a wide range of manufacturers and are in particular used in areas with high demands on performance and efficiency.

MAN D26 Fendt engine

To create an engine with a minimum of 500 HP for use in a powerful standard tractor without articulated steering that complies with Tier 4 final and EU Stage IV exhaust emissions standards, the engineers at MAN based their designs on the D2676 power train for trucks, adapting this to meet the requirements of a tractor.

The MAN Engines modular exhaust gas aftertreatment system is characterised by its high flexibility and extreme compactness, which is particularly advantageous for the varying and space-critical installation situations on workboats. The MAN Engines engineers have achieved this trend-setting result by means of freely positionable components and thus the most diverse variants of the EGA.

MAN engines in wood gas CHP units

In times of nuclear and coal phase-out, the question of a safe and clean energy supply is increasingly in the focus of power producers. MAN Engines has been offering solutions in this sector for decades, supplying CHP manufacturers with robust, clean gas engines. The use of special gases such as biogas and sewage gas has proven to be particularly sustainable and popular. But with wood gasification, a lesser-known technology has recently come back into focus. Here, too, MAN Engines and its partners serve a still small but steadily growing market with powerful gas engines.

Modular exhaust gas aftertreatment system for biogas CHP units

The 44th German Emission Control Act (Bundes-Immissionsschutzverordnung, BImSchV) has noticeably restricted the limit values for biogas CHP unit emissions. Operators are facing particularly strict emissions limit values for nitrogen oxide (NO_x). With its modular exhaust aftertreatment system, MAN Engines has been prepared for the new limit values. The project about minimising NO_x emissions during biogas CHP unit operation has been carried out by the Technical University of Munich (TUM).
