Accelleron at CIMAC 2025
May 19-23, 2025 | Zurich, Switzerland, Kongresshaus Zürich
Select section:
How can we equip today’s ships to deliver a net zero maritime future by 2050?
As the maritime industry begins the five-year countdown to a critical 40% carbon intensity reduction checkpoint in 2030, how can shipping companies use technology to pick up the pace and meet that target? How can we master the bigger challenge of delivering on the net zero ambition for 2050?
Join us at the 31st CIMAC World Congress, May 19-23, 2025, on Lake Zurich, in Switzerland, where we will share insights into our latest technological innovations to help solve those challenges. Our experts will present turbocharging and fuel injection innovations aimed at accelerating decarbonization and supporting the energy transition to future carbon-neutral fuels.
We’ll also join other stakeholders from shipping, energy, and other hard-to-abate industries, including 1,000 technology leaders from all over the world, to address the biggest challenge facing all of us: the scale-up of the carbon-neutral fuel infrastructure, the key to our net zero future.
Come meet Accelleron at one or more of these CIMAC activities!
10:00-12:40 Opening ceremony Keynote
Lynn Loo is CEO of the GCMD Professor of Chemical and Biological Engineering at Princeton University.
Prof. Loo is the inaugural CEO of the Global Centre for Maritime Decarbonisation (GCMD). Founded in August 2021, GCMD is a non-profit organization whose singular mission is to help international shipping eliminate its GHG emissions by (a) shaping the standards for future fuels; (b) piloting low- carbon solutions at or near commercial operations conditions; (c) co-financing first-of-a-kind projects; (d) fostering collaboration across sectors.
She is also the Theodora D. ’78 & William H. Walton III ’74 Professor in Engineering at Princeton University where I lead a team of researchers to develop emerging solar cell technologies based on hybrid and inorganic perovskites.
Prof. Loo co-founded Andluca Technologies, a startup for wireless smart glass to reduce energy use and increase occupant comfort in built environments.
She serves on numerous boards, including the Global Maritime Forum, an independent nonprofit organization committed to shaping the future of global seaborne trade. GMF focuses on decarbonizing the maritime industry and making life at sea more inclusive and appealing to people of all backgrounds.
9:00-10:40
Sequential turbocharging as performance enabler for demanding marine propulsion engines
Michael will present innovations in sequential turbocharging that can increase the performance and reliability of high-performance vessels that require a dynamic power capability to be able to transition quickly between low-speed maneuvering and high-speed cruising.
14:00-15:20
Strategic thinking on the four levels of AI
14:20-16:00
Design, modelling and performance of an OMT methanol port fuel injector for large marine engines
Marco will discuss the need to retrofit the existing global merchant marine fleet of over 100,000 vessels to make it able to run on carbon-neutral fuels, in order to meet the IMO’s GHG reduction targets of 30% by 2030 and 80% by 2040 compared to 2008 levels. With the existing fleet midway through its lifespan and new dual-fuel ships only beginning to emerge, retrofitting will be crucial for meeting the 2030 target.
As methanol has emerged as a preferred early transition fuel due to its earlier availability, lower toxicity, and simpler handling compared to ammonia, Marco will present research showing port fuel injection (PFI) as a viable retrofit solution, which could enable widespread engine conversions to methanol, potentially accelerating maritime decarbonization efforts.
9:00-10:40
Panel: Decarbonizing Marine Across the Value Chain
Panelists will explore strategies to fully decarbonize maritime operations, focusing on meeting the IMO's 2030 emissions targets in less than five years, while also accelerating the energy transition to achieve net zero by 2050.
11:20-13:00
Tailormade solutions for high-pressure direct injection of methanol and ammonia
Marco will present a new family of OMT high-pressure dual fuel injectors designed to allow both new and existing engines to run on carbon-neutral fuels. These new injectors integrate both diesel and carbon-neutral fuel nozzles into a single unit, addressing the challenges of high-pressure direct injection for methanol and ammonia in marine engines.
Marco will explain how the space constraints are accommodated, and the compression ratios and injection stages modified for dual fuel application. He will also discuss the application of flexible operating systems to make these dual fuel injectors suitable for engine retrofits.
14:00-15:20
New ACCX300-L turbocharger generation ready for future fuel applications
Simon will present innovations in its next-generation axial turbochargers focused on meeting modern engine requirements while taking a platform approach to increase flexibility and reduce complexity of service. The new design aims to increase power density, incorporate modular components like an exchangeable cartridge for rotating parts, and enable fuel savings through features like turbocharger cut-out for part load operation. Additionally, Accelleron is conducting material compatibility studies for future fuels like ammonia, methanol, and hydrogen to ensure their turbochargers remain viable as the industry transitions to alternative energy sources.
