Hydrogen is the most abundant element in the universe and is 14 times lighter than air, making it the lightest atom on Earth. Hydrogen has two main characteristics: it is invisible and odorless. Hydrogen emits no CO₂ while burning, and it can be produced 100% from green electricity. Hydrogen can be stored as a gas under pressure, typically at 350 bar or 700 bar, or as a liquid when cooled down to -253°C.
The BeHydro hydrogen engines have 3 different layers of safety to ensure redundant safety:
The first layer is provided by using high integrity components that are conforming to all the relevant class and safety requirements, e.g. pressure relief valves, double shielded gas feeding collector, etc.
The second layer is provided by leak detection software and control system. The H2 control strategy allows for safe and efficient operation of the system.
The third layer is the design of the H2 system to ensure no hydrogen can be trapped in a place where it could cause issues. The system is designed to have as a worst-case scenario a safe controlled venting of hydrogen from the top of the machine. Upon release, hydrogen dissipates extremely fast since it’s 14 times lighter than air.
On top of that, our dual fuel hydrogen engines offer operational safety by allowing an automatic and seamless switch back to liquid fuel operation if needed, ensuring reliability of the driving system.
The BeHydro hydrogen engines use proven technology and are designed to ensure long term and efficient operation. In addition to their long service life, they are also very easy to maintain. This saves costs and time for owners and operators.
We have developed 2 types of hydrogen combustion engines:
The first type is the dual-fuel version. This engine can run on diesel as well as on a mixture of hydrogen and diesel. In hydrogen mode, diesel is used to ignite the hydrogen.
The second type of engine can only run on hydrogen and has a spark igniter (or spark plug) to start the combustion of the hydrogen.
When the air is aspirated into the engine, hydrogen is injected under low pressure at the air inlet of the cylinders. A mixture of hydrogen and air is injected into the cylinder. In this way, hydrogen can never accumulate in the engine. By injecting (pilot) diesel, a flame is created that automatically burns all the hydrogen in the cylinder with it. Burning hydrogen generates heat and pressure which is the driving force for the engine to run.
