2 MEYER WERFT at a glance Family owned in 6th generation Two ship building docks, laser centre 3200 employees in Papenburg 1986: first cruise ship new build 2

3 MEYER group 3

4 CO 2 concentration (ppmv) Emissions Pollutants Greenhouse gases Harmful for health, poisonous, dirty air Harmful to the climate, Global warming Soot, particulate matter (PM) Carbon dioxide CO 2 4 Nitrogen oxides NO x Sulphur oxides SO x Unburned methane CH 4 Change of carbon dioxide content The industrial revolution has caused a dramatic increase in CO 2 concentration. Year (a. Chr.) glacial cycles Thousand years before

5 SO x, NO x, (PM) EEDI, ECA, MARPOL Regulations Emission Control Areas (ECA) 5 MEYER WERFT claim: Technological leadership Take a model role

6 Status quo 6 Demands: pollution-free renewable climate-neutral Challenge: Turn away from Heavy Fuel Oil

7 Energy storage for seagoing vessels 7 [MJ/l] Energy per volume of tank C Diesel Methanol LNG H2 Battery Akku Battery and H 2 not suitable for long distances

8 Less energy demand -> less effort: Energy efficiency 8 but efficiency alone is not enough Radiance of the Seas 2001 Celebrity Solstice 2008 Quantum of the Seas GT cabins 40.0 MW GT cabins 41.0 MW GT cabins 41.0 MW GT cabins 37.0 MW

9 Exhaust gas cleaning Scrubber Catalyst (SCR) Filter Clean fossil fuels Marine diesel, low-sulphur LNG (liquefied natural gas) Fuel Cells Technological steps 9 Electricity-based fuels (E-Fuels) Methane (liquefied) from Power-to-Gas Methanol/ Diesel from Power-to-Liquid

10 Regulations Contract Rule development: example LNG IMO regulations BunGas GasPax approximately 150 countries must agree , Norway: LNG-ferry Glutra (Interim-Guidelines) Same challenge for: Methanol Fuel cells

11 Mariella: Methanol & Fuel Cells 11 Methanol: Naturally liquid fuel Simple logistics Standard technology Fuel Cells: Successfully in use Highest efficiency -> Technically feasible -> Missing regulations block advantages

12 Reference 12 Well-to-Propeller Production Processing Transport chain Onboard consumption

13 Exhaust gas treatment 13 HFO with SCR and Scrubber MDO with SCR catalyst Well-to-Propeller Successful reduction of pollutants Well-to-Propeller

14 New: LNG engines 14 LNG C) AIDAnova, 2018 Well-to-Propeller Cleanest fossil fuel Technically sophisticated

15 Engines with renewable E-Fuels 15 Methane C) Methanol Methane from PtG Methanol from PtL Well-to-Propeller Operate existing systems with renewable fuels. Well-to-Propeller

16 Future: Fuel Cells 16 Fossil Renewable Well-to-Propeller High efficiency, no pollutants Well-to-Propeller

17 Decentral by fuel cells 17 Modularity, redundancy, autarkic firezones (FZ) Long-term replacement of all combustion engines

18 Energy quantities 18 Solar energy World energy demand on land surface 3, kwh/a 1, kwh/a Sufficient renewable energy available 8th AVL Large Engines TechDays Energiewende in Shipping

19 Responsible use of land 19 The future is in E-Fuels Source: Energiewende zu Ende gedacht, Ulf Bossel, 2017 ISBN

21 Summing-up 21 Technologies are available, but regulations are missing Clean fossil fuels as transition Wind and solar for electricity-based fuels (biomass not) Ship owners are ready and willing General conditions must enable them to use clean technology "Level playing field" through pricing of external costs
