 Framework conditions for maritime electromobility
 • Federal government: Providing framework conditions to strengthen the sustainability in the shipping sector [Bun17d]
 – Supporting the (further) development of globally valid climate and environmental standards,
 e.g. the international rules and regulations for the prevention of pollution from ships:
 in 1973 MAROL-Convention by IMO [IMO]
 – In principle, incentives should be created for the nationwide use of environmentally friendly ship propulsion systems
 – Federal states and port cities should be supported in the establishment of uniform approval standards
 – Alternative transport technologies are to be coupled with the production of renewable energies [Bun17d]
 • Federal states level: Structures to foster renewable energies and electromobility [Lanb], [LEK]

 Nature and environment protection in inland and coastal waterways
 • Only fuel with a maximum emission level equal to that of marine diesel without exhaust after-treatment are permitted to
 used in inland waterways [Umw13]
 • IMO: Emission limitation for seagoing ships [IMOa]
 • Additional incentives by commissions such as HELCOM (Helsinki Commission) [HEL17]
 or local specifications (e.g. port of Amsterdam) [Por17].

 Interests of shipbuilding participants
 • Historically no economically feasible alternative to conventional combustion engines
 • Holistic view of the ship design is needed
 • Iterative methodological selection and design of the (alternative) drive train required
 • Increased design effort for ship developers and ship builders,
 development of new competences required,
 shipyard independent development to strive for ideal technical solutions

 Development of national and international Rules and Regulations
 • European Committee for drawing up Standards in the field of Inland Navigation (CESNI)
  Since 2015: European Standard laying down Technical Requirements for Inland Navigation vessels (ES-TRIN),
 these are continuously optimized and extended [Eur17], [Eur18], [Eur19a]
 – Blueprint for the regulation of ship safety in inland navigation (Binnenschiffsuntersuchungsordnung- BinSchUO) which is
 completed by national specifications, if required [Was18]
 – 2017: Few chapters like "Electric Vessel Propulsion“ are vacant
 – 2019: New content regarding special provisions applicable to electric vessel propulsion
 • Due to the rapid development and bureaucratic processes, many issues are not yet addressed by official regulations
 • Alternatively, classification societies may be assigned for the approval of innovations [Nac15]

 SWOT- Analysis
STRENGTH WEAKNESSES
• Innovation capacity in Germany (industry and science) • High degree of oil-pricing dependence
• Existing funding structure • Financially weak sector
• Approx. 1/5 of the electric energy from renewable energy sources • Competition with road-based electromobility
• Battery disposal: Careful handling • Lack of standardisation in charging infrastructure
• European recycling structures • Lack of transmission grids and consumption deficits often require
• Almost every recreational craft jetty is equipped with power supply temporary shutdown of renewable energy producers
 • Almost no exception regarding the exemption from the EEG-Umlage
 (Renewable Energy Sources Act)
CHANCES RISKS
• Storage of excess electricity (reduction of residual load) • Realisation of immature solutions
• Reduction of electricity transportation hauls • Slow implementation can gamble away the technological lead
• Increased attractiveness of inland navigation shipping • Insufficient documentation of project findings
• Development of innovative tourism concepts  Loss of knowledge
• Basic research, R&D impulses • Knowledge leakage
• Further development of expertise (e.g. overseas) (by industrial spying, own publications, staff emigration)
• Expansion of the public transport system without increasing • Lack of infrastructure or high expenditure of time for installing the
 emissions infrastructure can cause delays in establishment of electromobility
• Decreasing battery prices accelerate the growth of electric mobility • Negative public perception due to safety-critical incidents
• International leading position within the sector of electric mobility (e.g. burning batteries) especially with human injury
• Growth in economy due to synergy effects
• Portfolio extension for companies from other industry sectors
 (electro mobility, automation, digital safety, additive manufacturing)
• Reduction of environmental and noise pollution

3 INVESTIGATION AND PRESENTATION OF ENERGY CARRIER RELATED INFRA STRUCTURE

BRIEF OVERVIEW OF COMMERCIAL SHIPPING (1)
 27

 Why do construction, ship, jetty and charging infrastructure have to be seen in context?

 Schedule,
 profitability
 Onshore: Energy supply Battery mass
Ship: Charging Charging
 Charging & volume Costs
 infrastructure logistics duration
 infrastructure Battery
 capacity/
  Mooring lifetime
  (Electrical) connection
  Entries and exits Energy Ship design
  Automation demand (e.g. draught)
 • Safety
 • Staff and time savings

 Which role plays the examination of construction documents within design phase?

 Initial situation Preparation/ derivation of official regulations and rules
 • Based on approval documents of the classification societies
 Examination and confirmation by the classification societies within the early design phase
 Goal • Approval by national and international authorities, coverage of not existing regulations
 Poor regulatory situation
 • High number and speed of new developments
 • Risk of non-approval of innovations or design adaptations

3 INVESTIGATION AND PRESENTATION OF ENERGY CARRIER RELATED INFRA STRUCTURE

BRIEF OVERVIEW OF COMMERCIAL SHIPPING (3)
 29

 What are the challenges for refuelling with alternative fuels?
 • Methane: Methane slip- 25 to 30 times of greenhouse gas effect compared to CO2 [DNV18]
 • Hydrogen: Highly inflammable blend at standard temperature and a volume ratio of 4-75% [Cam18]
 • Ammonia: Toxic and caustic gas [Wik18e]
  However, risks are limited and the technology is mostly used since many years

 What depth are needed for tenders of new construction/ modification of electric inland navigation vessels?
  Tender documents for a new construction or modification must be adapted to the energy-carrier-related
 infrastructure
 • Abandon flexibility while docking and charging
 • Minimize energy reserves
 • Specify the operating profile and additional requirements as precisely as possible,
 e.g.: Distance, schedule, payload, hotel load, operation conditions etc.
  e.g.: Facilitates optimized weight and battery design
