Programme

22.09.2025

8.30 Uhr Registration
9.00 Uhr Welcome by Nicole Schenk, STG Board Member
Session Session 1 Fuel Flexibility
chaired by Dr. Christoph Schladör, Vice President Decarbonisation Carnival Maritime GmbH
Production an availability of alternative fuels
9.25 Uhr Big scale production of E-Methanol – are there enough capacities for the demand?

  • No technical barriers to scaling eMethanol: The ingredients are in place—renewable energy, CO₂ sources, and proven technology. What’s needed now is market alignment: long-term offtake agreements, regulatory clarity, and investor confidence.
  • eMethanol is a global defossilisation solution: It’s not just for shipping, but also for chemicals, road transport, and as a feedstock for sustainable aviation fuels. Demand is emerging across sectors and regions—supply will follow.
  • First projects need targeted support: As global hydrogen production ramps up, eMethanol will become increasingly cost-competitive. Integrating methanol into hydrogen or ammonia projects is technically simple—what’s needed now is the right policy environment and risk-sharing mechanisms.

Thorsten Herdan, Chief Executive Officer, HIF EMEA GmbH

Propulsion improvement
14.25 Uhr Increasing efficiency by retrofitting of propellers – an excellent measure for existing vessels
Dr. Lars Greitsch, Managing Director, MMG
14.55 Uhr Improvement of ship efficiency by optimization of rudder and installation of propulsion improving devices

  • Energy Saving Devices like twisted rudders or propulsion improving devices offer a practical, cost-effective retrofit solution to improve ship efficiency and meet environmental regulations by reducing fuel consumption and CO₂ emissions.
  • Energy Saving Devices have a proven performance and optimized design via CFD and/or model testing. They are installed across different vessel types, from slow-going vessels like tankers and bulker to slender vessels like container ships.
  • The installation of these devices is easily done for both newbuildings and retrofit projects during routine dry-docking, making them attractive for shipowners seeking minimal operational downtime.
