5Alternative futures for shipping MusclesWindCoalOilShipping has used many different sources of energyOil has dominated the last century, it’s now time to look for new types of fuel. Driven by:Environmental concerns – new regulationsIncreased oil pricesNew technologies
8Fuel price – HFO, MGO, LNGAdd price development of methanol, one can be sure that low sulphur HFO alternatives are being developed, as refinery owner and oil company Preem in Sweden are aiming for low-suplur HFO alternatives to be present during 2015 at a price slightly lower than MGO alternatives.
11MGO and low sulphur oils Price development of MGO is predicted to rise (EIA).Oil companies and refinery owners, for example Swedish Preem, are working to deliver low-sulphur oil blends to the market before , most probably strategically priced slightly below MGO alternatives.To comply with upcoming NOX regulations, EGR or SCR technology needs to be installed on board ships.
12LNG case studyCurrently 49 ships in operation, 61 in orderbook and >100 projects discussed (DNVGL, 2014)Liquid methane can also be produced from bio feedstock forming LBGSafety record satisfyingNew infrastructure investments required for small scale distribution networks.Question of future LNG bunker price developments.LNG in four-stroke technologies complies with future SOX and NOX emissions caps without extra abatement technologies.Cryogenic storage tanks demanded on board vessel

15LNG case study – Baltic SO2lution Four newbuilt tanker vessels, first to be delivered in 2016.First installation of 2-stroke-engine technology for LNG complying with upcoming NOX and SOX requirements.
17Methanol case study Global commodity (55 million tons annually) Can be produced from various feedstockExiting global infrastructureLiquid at room temperature, can be stored in similar tank on board and ashore as oil productsSimilar reductions in air emissions as LNG (CO2, NOX, SOX, PM)Retrofits need significantly less adjustment than LNGToxicQuestion on price development for marine marketToday large retrofits and newbuilds planned, but still in trial stages
19Methanol case study – Stena Germanica conversion Length 240 mBreadth28,7 mDraught6,15 mCargo Capacity4000 lane metersPassenger capacity1300Main engines4 x Wärtsila 8ZAL40S, 6000 kW
20Scrubber case study Continued use of heavy fuel oils Aftertreatment of fuel gases extracts sulphurAdditional techniques needed to minimise NOX levels in outlet gasesFlexible solution suitable for ships without fixed bunkering points over timeTechnically complicated, both regarding the scrubber itself and technically for the ship
24Methanol case studyRules are in place for methanol in the IMO IGF –code and Class rules ( LR & DnV)Low flashpoint fuel like LNGFlashpoint Methanol + 11 C.FlaspointLNG -188 C.Self ignition Methanol+ 465 C.Self ignition LNG+ 595 C.Infrastructure and safety similar to ethanol and petrolLiquid –no high pressure or cryogenic storage required
25Scrubber case study – Pilot scrubber Installation, evaluation and demonstration of a new generation, innovative lightweight scrubber technology in full scale on existing Ro-Ro vessels TransAtlantic Transpaper type and Wagenborg Schieborg, operating in the Baltic Sea and in the North Sea.
