CMB.TECH's core technology focuses on hydrogen combustion technology, hydrogen storage and hydrogen/ammonia implementation. The knowledge and experience has been gathered through more than 15 years of designing, testing and operating cleantech systems. CMB.TECH has developed a wide range of applications ranging from ships to trucks and from gensets to excavators. For the development of medium and high speed H2ICE, strategic development agreements have been signed with several OEMs and engine manufacturers.
What is ICE (Internal Combustion Engine)?
A hydrogen combustion engine (H2ICE) is a combustion engine that uses hydrogen (monofuel H2ICE) or a mixture of hydrogen and diesel (dual fuel H2ICE) as a fuel.
Combustion engines have a major role in energy demanding industries. Many applications are built around the combustion engine, which has proven itself to be a reliable workhorse for many decades. The design has been optimized through years of experience and answers to the questions of affordability, maintainability and reliability. As being the preferred technology for heavy duty applications, diesel engines are responsible for a significant portion of the worldwide CO2 emissions. Since heavy duty applications are built for a long lifetime and are capital intensive, it is important to consider proven technologies to allow these platforms in making the energy transition happen.
Heavy-duty applications run often with high power and are making multiple shifts during a day, making it very hard to electrify. With CMB.TECH’s dual fuel technology, heavy-duty applications such as ships, locomotives, trucks, port/mining/construction equipment and gensets can already save 60% of the emissions today and the technology has already proven itself to increase the savings further up to 85%. By using pure hydrogen combustion technology, 100% savings can be achieved by. This technology is developed by CMB.TECH and is already being used successfully in commercial applications. The dual fuel technology allows the clean fuel infrastructure to grow and to mature, without being dependent on the supply of the clean fuel.
Dual fuel technology has the unique capability to offer the highest emission’s savings for the lowest CAPEX investment.
Besides engine developer, CMB.TECH is also an integrator of clean hydrogen and ammonia storage.
Compressed hydrogen is the preferred solution if one can refuel on a regular basis. Ammonia is more suitable if the stored energy outpaces the realistic possibilities with hydrogen and if the toxic properties can be handled safely.
Compressed hydrogen storage has proven itself since more than 50 years as a safe and reliable technology. The complete package of design, integration and commissioning of the hydrogen storage system is performed by CMB.TECH’s engineering team. The storage system comprises of smart sensors and a control unit which is programmed with a proprietary static and dynamic leak test algorithm. Also on the refuelling and the necessary safety aspects of operating and maintaining hydrogen systems, CMB.TECH has developed standardized solutions and protocols tuned to the application.
As we have developed world’s first class approved hydrogen powered ferry, we are able to translate the gathered experience into improved standards for our hydrogen storage solutions.
Ammonia storage is mainly developed for use on our large ocean-going ships. Dependent on the size of the ship and the operational constraints, we select IMO type A, B or C tanks, which can on our largest vessels hold up to 6000 cubic meters of refrigerated ammonia. Both liquefaction and pressurized system are considered in our ammonia powered ships to keep ammonia in its liquid state. For the design and construction, CMB.TECH has established preferred partnerships with world’s renowned specialists to build the latest state of the art chemical tankers, container vessels and dry bulk carriers.
Advantages over other technologies
The technology has clear advantages over other low and zero carbon alternatives.
1. Cost : Optimized balance of maximized emission’s savings while ensuring that the extra required CAPEX is minimal.
2. Reliability : combustion engines are robust, reliable and have a long operational track record
3. Zero carbon : ICE monofuel engines reduce greenhouse gas emissions to zero, ICE dual fuel engines reduce emissions by 60 to 90 % depending on the load and the engine type
4. Available today : large marine and industrial applications can be converted to H2ICE today
Dual fuel engines offer the added advantage of full diesel back-up in case hydrogen is not available or too expensive. This is a very important added benefit for industrial and marine operators.
