This diverse and multidisciplinary consortium is united by a common mission: to develop a pioneering energy conversion system that will significantly lower carbon emissions in the shipping industry.
The project’s focus is on creating a versatile and efficient energy system that can use a wide array of sustainable fuels, such as green methanol, hydrogen, and ammonia. One of MARPOWER’s most notable goals is to ensure that this system requires little to no modifications to existing ship combustion systems, making it easier for operators to transition away from conventional fossil fuels without major overhauls. By targeting flexibility and practicality, the initiative aims to make sustainable fuel adoption more feasible and cost-effective for the maritime sector.
Pioneering a Flexible Energy Solution for the Seas
The core of MARPOWER’s innovation lies in the development of a state-of-the-art gas turbine combustor, engineered specifically for alternative fuels. This advanced system is designed to maintain high efficiency and performance, regardless of the sustainable fuel in use. The project also includes the creation of a sophisticated active magnetic bearing (AMB) system, which supports a two-shaft gas turbine combined with a bottoming cycle. This configuration maximizes energy production and utilization on board ships, allowing for improved power generation for both propulsion and other energy needs.
A central challenge in developing the MARPOWER system is ensuring its economic viability. To address this, the project team is working to optimize the energy conversion process, ensuring that the new technology is not only technically sound but also commercially competitive. By keeping costs in check and minimizing the need for extensive ship retrofits, MARPOWER aims to ease the transition for shipping companies looking to adopt greener technologies.
Digital Twin: Revolutionizing Testing and Validation
A crucial element of MARPOWER’s approach is the use of a digital twin model to integrate and validate the new energy system’s performance. This virtual replica mirrors the physical system and its components, allowing for comprehensive simulation and analysis of energy conversion processes in a controlled environment. By using a digital twin, the team can replicate various conditions and scenarios that ships might encounter at sea, making it possible to fine-tune the system’s functionality before deploying it in real-world conditions.
The digital twin will play a vital role in assessing the system’s efficiency across different types of vessels, including cargo and cruise ships. It will enable simulations for both electric propulsion and cogeneration applications, which involve using the system’s waste heat for secondary energy needs onboard. This innovative testing approach reduces the risks associated with deploying new technologies at sea, offering a safer and more efficient pathway to cleaner maritime operations.
Prototyping and Real-World Testing: Ensuring Reliability
In addition to virtual simulations, MARPOWER’s success hinges on the development and testing of physical prototypes for critical components of the system. These include the combustion chamber, high-pressure shaft system, and recuperator, all of which are essential to achieving optimal system performance. By creating and rigorously testing these prototypes, the consortium aims to refine the system’s design, ensuring that it can withstand the unique challenges of maritime operations.
One of the more complex aspects of the project involves creating a moving platform that simulates the motion of a ship at sea. This testing environment will allow researchers to observe how the AMB system functions under conditions that closely mimic real-world ship movements. By simulating such scenarios, the project aims to address potential issues early in the development phase, thereby enhancing the reliability and safety of the final product.
A Collaborative Effort for a Greener Future
The MARPOWER project’s success is driven by the collective expertise and innovation of its consortium members. Alongside LUT University, the Finnish companies Aurelia Turbines and Alfa Laval Aalborg bring their specialized knowledge in turbine and heat exchanger technology. From Italy, Politecnico di Milano and Rina Consulting and Services contribute with their expertise in engineering and certification. The University of Vigo and Zabala Innovation from Spain, the German Aerospace Center (DLR), the Technical University of Denmark (DTU), and France’s Chantiers de L’Atlantique round out the consortium, each playing a crucial role in advancing the project’s goals.
This diverse partnership highlights the importance of international collaboration in addressing global challenges like climate change. By pooling their resources and expertise, these organizations aim to create a solution that can be widely adopted across Europe and beyond, ultimately setting a new standard for low-emission maritime transport.
The Broader Impact of MARPOWER
The implications of MARPOWER extend far beyond the immediate benefits to the shipping industry. As one of the largest sources of global carbon emissions, the maritime sector has a significant impact on climate change. By developing a system that enables ships to use cleaner fuels, the project not only reduces greenhouse gas emissions but also contributes to lowering marine pollution, including sulfur oxides (SOx) and nitrogen oxides (NOx), which can harm marine life and ecosystems.
Moreover, MARPOWER’s focus on renewable energy sources like hydrogen and green methanol aligns with the EU’s broader climate goals, including achieving net-zero emissions by 2050. The project is seen as a critical step towards meeting these targets, offering a practical pathway for decarbonizing one of the hardest-to-abate sectors. It represents a shift from short-term solutions, such as LNG, towards a future where zero-emission technologies become the norm in maritime transport.
Overcoming Challenges and Looking Ahead
Despite its ambitious vision, the MARPOWER project faces several challenges. Transitioning an industry as large and complex as maritime transport to alternative fuels is no small task. Factors like fuel availability, infrastructure development, and the cost of new technologies must be carefully managed to ensure the project’s long-term success. Additionally, convincing ship owners and operators to adopt new systems will require a clear demonstration of the economic and operational benefits of switching to greener solutions.
The project’s approach to overcoming these challenges lies in its focus on flexibility and adaptability. By designing a system that can work with multiple types of sustainable fuels, MARPOWER aims to provide a solution that can adapt to changing market conditions and technological advancements. This adaptability will be key to ensuring that the project’s outcomes remain relevant as the energy landscape evolves.
Looking forward, the MARPOWER team is optimistic about the potential impact of their work. If successful, the project could pave the way for a new generation of energy-efficient, zero-emission vessels, making significant strides towards a more sustainable future for global shipping. With its blend of advanced technology, collaborative effort, and a commitment to environmental stewardship, MARPOWER is positioned to be a game-changer in the race to decarbonize maritime transport.
