Future Infrastructure International Shipping (1) the most efficient mode The international shipping industry is responsible for the carriage of 90% of world trade and is the lifeblood of the global economy. Shipping is the most energy efficient mode of transport.

International Shipping (3) Non-Annex 1 countries Presence of Non-Annex 1 countries One of characteristics of the international shipping is great presence of Non-Annex 1 countries now, and increasing. 1. International Shipping (4) Transport Demand in 2050 OPRF* undertook a major study where transport demand in ton-miles by ship types is projected towards 2050 on the IPCC A1B scenario**. Container movement in 2050 was estimated 7 times as much as in Ton-mile index of container movement on A1B 2050 scenario (2005=1) 5 To N America E Asia Europe S America M East India Africa Oceania Total From N America E Asia Europe S America M East India Africa Oceania Total Source : OPRF* = Ocean Policy Research Foundation, Japan (2008) ** IPCC : Intergovernmental Panel of Climate Change A1B scenario : High growth scenario, balance of fossil/non-fossil energy 6 1. International Shipping (5) Emission Curves Contents CO2 emission from the international shipping in 2050 is estimated 4,817 million ton on A1B scenario, and 2,957 mill ton on B2 scenario*, if no improvement of ships efficiency. It is of great importance for the international shipping to challenge the reduction of CO2 emission.

3 2. Future Ship Design (1) Utilization of Land Electricity 2. Future Ship Design (1) Utilization of Land Electricity In order to reduce the exhaust gas emission at port, land electric power is used with connecting a cable to ship power system. It is called as AMP (Alternative Marine Power) system or Cold Ironing. Now, more than ten container vessels of NYK are equipped with this system. Mobile Container Type Wiring Diagram Fixed Type Supply Power from Land Side No Engine Operation Reduce CO2 Emission Future Ship Design (2) Solar Power 6200 units PCTC MV Auriga Leader, delivered in December 2008, is equipped with 328 solar panels that generate 40kW. The solar power system connects to ship propulsion system. The system supplies up to 6.5% of the electricity used on board, and CO2 emission from the vessel is expected to be reduced by 0.3%. Now testing the durability under stress from salt water and wind pressure for future full-scale implementation. MV Auriga Leader 2. Future Ship Design (3) Air Lubrication Air causes less friction than water by reducing the contact surface between the water and the ship s hull. Air lubrication system will be installed on new ships of NYK-Hinode Line, shallow draft with wide flat bottom, delivered in 2010 at Mitsubishi Heavy Industries, Japan. Actual power saving, after deduction of the power consumption needed to utilize the system, will be about 10%. Solar panels in future 11 12

Reduce the Lightweight 20% of displacement can be reduced by using aluminum alloys, composites and sandwich structures, no ballast as a result of optimizing main dimensions and stability The total power required can be reduced by 9 12%

5 Reduce Skin Friction Recent research shows that the bio-fouling causes up to a 15% increase in ship resistance. It is effective to find the solutions to prevent the fouling with surfaces that use nanotechnology, shark s skin, etc. Nanotechnology Shark s Skin Solar Power The container cover area and sails which can be used as solar cells base is 31,000m2. The solar cells are of thin film cells. Dairy average output will be 1-2 MW on the basis of 30% conversion factor in Sails The vessel is equipped with 8 foil sails. Each sail is about 500 m2. The sails can be taken down by means of a telescopic system. The power saving by sail propulsion can be 1-3 MW. Sails location Sails stored Fuel Cell One of the most promising concepts is the use of fuel cells for main power generation. Total required power of fuel cells is around 40 MW for NYK Super Eco Ship 2030 with capacity of 8,000 TEU whereas today s ship needs 64 MW. Fuel cells of NYK Super Eco Ship 2030 is LNG based. When the technology of hydrogen fuel cells become applicable to ships, expected around 2050, CO2 emission from ships can be zero

Select best auto pilot setting by comparing FOC index. Red line : OG speed Blue line : Rudder angle FOC index (Mile/Ton) was getting lower at a constant rpm with the autopilot. OG speed was getting a little slower because there was beam wind and counter rudder angle was about 3 degrees. Resistance by rudder was the cause of performance down. Combine with weather routing by actual sea margin analysis. Trend Image of Average Vessel Speed per Hour Automatically output summary data Red : Ground Speed Black: Speed through Water 3.

11 IMO MEPC (Marine Environment Protection Committee) agreed : 1. a package of technical and operational measures, i.e. a. formula of Energy Efficiency Design Index for new ships b. guidance of Ship Energy Efficiency Management Plan for voluntary use to monitor and improve performance. 2. a work plan for further consideration of market-based measures a. Various proposals Emission trading scheme, Bunker levy,... What kind of market-based measures are appropriate for the international shipping? 41 Market-based Measures Reduction of CO2 emission from the international shipping Reduction of activities Improvement of ships efficiency Improvement of ships efficiency should be a primary option Purchasing emission credits from other sectors Is it an appropriate solution? How to spend our revenues to reduce CO2 emission invest in building energy efficient ships? purchase credits from other sectors? 42 A simple simulation to compare purchasing emission credits and Improving ships efficiency. A shipping company will order a new vessel in Assume that the price of a saving-energy equipment will be twice of the price of emission credit in It is too hard for the company to install the equipment onboard. However, if the price of emission credit will increase year by year... The new vessel will be delivered in During several years, the company will be very satisfied because emission credit is cheap enough. However, after several years, the situation will be changed. The life of the vessel is 25 years or more. As the result, total life cycle cost of purchasing emission credits will become bigger than one of Improving ships efficiency. > 43 Even if Emission Credit is one of good market-based measures, it is not perfect from the view point of this result. 44

12 Closing Remarks Refund Scheme proposed by The Japanese Shipowners Association Collection: A vessel B vessel C vessel strong incentives Refund: Maritime GHG Fund Other use: R&D of new technology Mitigation & adaptation projects GHG contributions are collected from each vessel, based on the purchased volume of marine bunker, and transferred to the Maritime GHG Fund. Majority of the collected contributions are refunded to vessels that have improved energy efficiency. The refund creates strong incentives to encourage shipping companies to improve ships efficiency. A part of the contributions is allocated to finance R&D of new technology and mitigation and adaptation projects in developing countries. 45 The shipping is the most environment-friendly mode of transportation. Trend of CO2 emission from the international shipping is determined by the growth of global economy. Imposing emission capping is not appropriate approach. There is high potential of the efficiency improvement of the international shipping. Regulatory framework should be effectively established to provide strong incentives for the shipping industries to invest in the efficiency improvement of the international shipping. Invest in building energy efficient ships purchase credits from other sectors 46 Thank you for your attention 47
