Mission Net Zero

At Mitsubishi, we are committed to achieving net zero emissions and creating a sustainable future. Our reliable and easy-to-maintain engines, generator sets, and energy solutions are designed to help you reduce your carbon footprint and contribute to a cleaner environment.

We hereby make the declaration of achieving Carbon Neutrality by 2040

MHI has defined two growth areas to focus on in its 2021 Medium-term Business Plan: "Energy Transition," which aims to decarbonize the energy supply side, and “Smart Infrastructure,” which aims to realize decarbonization and promote energy efficiency and labor savings on the energy demand side.

At Mitsubishi Turbocharger and Engine Europe (MTEE), the "Energy Transition Initiative" is demonstrated through the development of new technologies focused on lowering CO2 emissions, primarily targeting the maritime sector, which has the highest CO2 emissions among the (standby engine) markets we serve.

2040 Carbon Neutrality Declaration Of MHI Group

Realizing a Carbon Neutral society is a global issue and MHI believes that as a technology leader, with a proven track record in the field of decarbonization, it is MHI’s responsibility to help lead the fight against climate change. To this end, MHI will embrace the "MISSIONNET ZERO" initiative and work with clients, partners, academia, and governments to implement a net-zero future.

#EnergyTransition In Engine Industries

Mitsubishi Engine is committed to supporting the MHI Group's "MISSION NET ZERO" initiative. We contribute through innovative technology and sustainable strategies in the Marine and Industrial industries to advance decarbonization in our operations.

HVO

All Mitsubishi engines are approved to run on Hydrotreated Vegetable Oil (HVO), a renewable, second-generation biodiesel derived from various raw materials. HVO offers significant sustainability advantages, including up to a 90% reduction in CO2 emissions (according to Neste) and contributing to better air quality. It is nearly identical to conventional diesel, so it can be used in engines without any modifications. While blends with more than 30% HVO may slightly impact performance and fuel consumption due to differences in density and heating value, the use of HVO generally does not significantly alter existing maintenance schedules.

Methanol

In the long term, inland shipping is expected to transition to hydrogen, especially for vessels covering longer distances. To reduce emissions in the short term, methanol is seen as a transitional fuel. Mitsubishi is developing a Dual Fuel Methanol/Diesel Retrofit Kit that allows existing engines to be easily converted. Prioritizing the development of these kits for marine engines is an essential step toward achieving a sustainable future.

After treatment

Mitsubishi complies with the stringent European Stage V and maritime IMO III emission standards. Stage V focuses on reducing harmful emissions for non-road mobile machinery, such as nitrogen oxides (NOx) and particulate matter. IMO III, aimed at vessels, lowers NOx emissions in controlled emission areas. To meet these requirements, Mitsubishi uses advanced technologies, such as particulate filters and selective catalytic reduction (SCR).

Hydrogen

Mitsubishi and Koedood are working on a significant advancement in the greening of European inland shipping: developing a spark-ignited hydrogen engine. Both companies are part of the Green Transport Delta Hydrogen project, an initiative by the Dutch government to establish a ship engine powered by hydrogen after an extensive testing phase of the engine by TNO, Koedood will proceed with building and installing the generator on a test ship. The hydrogen engine is based on the Mitsubishi S6R, a well-known and proven engine and technology. This also makes the transition very accessible for both mechanics and future operators.

Mitsubishi Hydrogen Engine / Generator set Milestones and Progress Toward Net Zero

The development of the hydrogen engine marks a turning point in the evolution of our combustion engines. The engine is designed and engineered following strict procedures, ensuring our high-quality standards.

2023 - Single Cylinder Research Engine (SCRE)

In line with traditional Mitsubishi practices, developing a new engine begins with constructing a single-cylinder research engine (SCRE). This step-by-step approach provides valuable data, which is then applied to developing the 6-cylinder engine.

The single-cylinder test engine is then subjected to extensive testing on the test bench, conducted by TNO’s (Dutch (Organization for Applied Scientific Research) leading engineers.

2024 - Prototype Hydrogen Engine

Our engineers designed and built the prototype based on the test results in our workshop, using the existing S6R-MPTAW engine as the foundation. We took one of our proven diesel engines as a starting point and changed the fuel injection system so the engine could handle hydrogen. The aim was to minimize modifications to the existing engine room setup, making the transition accessible for mechanics and future operators.

Similar to the SCRE, the S6R-MPTAW undergoes extensive testing by TNO experts. Data such as temperature, vibrations, noise, fuel consumption, power output and torque are thoroughly analyzed.

2025 - Build of Generator set

Koedood Marine Group, also based in the Netherlands, will build the generator. This generator powers an electric motor, which will ultimately be used for the ship's propulsion. In recent years, Koedood has gained significant experience with hydrogen, primarily in combination with fuel cells.

2025 - Installation of Generator in Vessel
