Hydrogen Combustion Engine
CMB.TECH has developed a dual fuel hydrogen technology.
The principle of the technology is presented in the following 5 steps.
Step 1:
Hydrogen is injected in the aspirated air during the intake stroke.
Step 2:
During the compression stroke Hydrogen mixes into a homogeneous mix.
Step3:
A small amount of diesel pilot fuel is injected into the combustion chamber just before top dead centre.
Step 4:
Diesel auto-ignites due to the high temperature and pressure and co-combusts with all the hydrogen, forcing the piston down during the power stroke.
Step 5:
The cylinder is cleaned during the exhaust stroke. Due to hydrogen co-combustion, the NOx and CO2 emissions have strongly reduced in the exhaust gases.

As part of its journey towards becoming carbon neutral by 2030, without the use of offsets, Vestas will explore how the world's first hydrogen-powered crew transfer vessel (CTV), the Hydrocat 48, can help reduce carbon emissions from its offshore service operations. Vestas does this by launching a pilot program in collaboration with long-term supplier Windcat Workboats.
Ports of Stockholm and CMB.TECH are joining forces in a unique hydrogen collaboration at Stockholm Norvik Port. The investment in hydrogen will encompass port operations and will also expand service offerings to shipping companies and haulage firms, as well as other customers and collaboration partners. The goal is for Stockholm Norvik Port to be Sweden’s most climate-smart and sustainable port.
