Milestone: 0,5% SOx in marine sector worldwide by 2020

Current: 0,1% SΟx in ECA – 0,1% SΟx in all EU ports

How can we achieve the targets set by current and upcoming regulations?

Low-Sulphur Oil

Low-Sulphur distillate oil (MDO-MGO) Hybrid fuels – Oil blends

No CAPEX

X High fuel costX Lower viscosity and lubricity than HFO X Different ignition and combustion

characteristics Increased maintenance to piston rings and valves

X Availability of the fuel - refineries

No CAPEX Better fuel characteristics in terms of

viscosity, lubricity than low-Sulphur distillate oil

X Compatibility with HFO engines?X Fuel quality – ship safety?X Availability of the fuel - refineries

Open loop Closed Loop Hybrid

Use HFO Low CAPEX (100-180€/kW) Low required space

X Prohibited to some European ports/

X Difficult to operate in swallow ports due to sand

X Efficiency dependable on water alkalinity

Use HFO Compatible to all ports

X High CAPEX (350-400€/kW)X Chemicals (caustic soda) for

the freshwater medium inside the ship

X High required space (Space for freshwater tank, heat exchanger, sludge management)

Use HFO Compatible to all ports Flexibility

X Complicated operationX High CAPEX/OPEX

Proven technology (100+ vessels in operation)

No SOx, PM (Regulation coming?) Low NOx CO2 reduction (MRV – higher CO2 costs

next years) Lower price than MGO

X High CAPEX for ship retrofit (3-20 M$) –Attractive payback where LNG market exists

X Space for LNG tanks on ship (lower energy capacity than diesel)

X Limited (but growing) availability of bunkering infrastructure in South Europe/Non-ECA Areas

Fuel Source: Natural Gas, Biomass, CO2

Environmental-friendly (Similar to LNG) No need for cryogenic tanks Available technology Low infrastructure costs (liquid fuel) Lower retrofit cost than LNG (5-10m€) Green source, if produced by RES

X Low energy capacity X High energy content price (similar or

higher than MGO) X High energy demanding process – high

production costs (need for RES electricity?)

X High toxicity

Reduce emissions, noise when in port/low speeds Run engines at optimum loads Avoid transient engine loads Use shore power Be able to combine RES and other technologies

X No change to fuelX High battery costs (projected to 500 USD/kWh or lower in few years)

Fuel Cells for Shipping

Solid Oxide Fuel Cell (SOFC)

Proton Exchange Membrane (PEM) / HT PEM

Source:EMSA

No CO2 emissions (hydrogen only) High power to weight ratio (100- 1000W/kg)

X Only purified hydrogen as fuel–Sensitive to contamination

X Need external reforming for HCX No waste heat recovery – low

working temperature (PEM)

Fuel flexibility (LNG, methanol) Internal reforming High efficiency (60% (with heat

recovery up to 85%)

X Higher required space than PEM

Suitable for auxiliary engines/hybrid ships

Summary

Scrubbers and distillate fuels/oil blends are a viable option to comply with the new emission regulations by 2020

BUT• Open-Type scrubbers are prohibited to some European ports• Viable with HFO as main fuel (Will be available in the market after 2020?)• Distillate fuel/oil blends require investments in refineries

LNG is the most promising and viable alternative fuel, but requires high investments in ship retrofit/new builds and terminal infrastructure

Methanol is ready-to market and could be a viable option, but it is currently expensive compared to MGO and HFO

Battery/Hybrid and fully electric ships are hot technological applications nowadays, best suitable for low speed operation (hybrid) and short-distance ships (ferries) (fully electric)

Fuel Cells in shipping sector is a high efficient innovative technology, ready to be combined with other fuels in hybrid ships, but currently expensive, with limited availability, reaching power of hundreds of KW.
