Dolphin N2 in Japan. How has the IMO shipping emissions agreement impacted on the shipping/marine industries & how can CryoPower lead the way?
Dolphin N2 have recently attended a “United Kingdom startup and venture capital” seminar at the British Embassy, Tokyo. Dolphin N2, with the help & assistance of the Department of International Trade, the Foreign & Commonwealth Office, The British Embassy & Shige Kasahara of Ricardo Plc; were given an opportunity to present to venture capital investors, with a view to creating international trade opportunities for the Dolphin N2 CryoPower engine technology.
Japan is one of the largest manufacturers of shipping engines, container ships & shipping tankers in the world. Korea, China & Japan account for more than 85% of global shipping production. While 32% of container ships & 30% of tankers produced in 2017 were made in China, Japan followed with shares of 12% and 14% (1)
As a major player in the shipbuilding industry, Japan is investing heavily to ensure that their ships conform to the Co2 emissions rules set down by the IMO (International Maritime Organisation) in 2018. The IMO have subsequently enforced under a new international agreement, that shipping Co2 emissions must be halved globally by 2050.
The IMO (International Maritime Organisation), in collaboration with the GIA (Global Industry Alliance) created GloMEEP (Global Maritime Energy Efficiency Partnerships) which has been implementing energy efficiency measures for shipping’(2)
Simon Brewster – CEO Dolphin N2 & acting in his role of a representative of Ricardo Plc, is one of the GIA signatories. Having attended the GIA 4th Task Force on Tuesday 27th November 2018 at the IMO Headquarters in London, Simon Brewster was party to the discussion of how the GIA can support the IMO in the development of measures that can increase the uptake of low carbon fuels.‘(3)
The 15 members of the GIA which represent leading shipowners/operators, classification societies, engine/technology builders & suppliers, data providers, oil companies & ports, are seeking ways to implement the GloMEEP strategies. The 4th Task force meeting focused on the adoption of low carbon fuels in the shipping sectors. ‘The meeting agreed, as a next step, to hold a GIA roundtable early 2019 to discuss how early movers could be incentivised to invest in alternative fuels. ‘(4)
Japan has a long history of innovations in the automotive & vehicle industry – road & non-road & have had some considerable time to establish themselves before a global audience. When you consider that Toyota is 83 years old, Suzuki is 109, Mitsubishi is 149, Hitachi 109 & Daihatsu is 111; is it any wonder that Japan continues to thrive in the supply of global transportation solutions?
With this in mind, we consider what some Japanese manufacturers are already undertaking to ensure their emissions are reduced & how the Dolphin N2 CroyPower engine technologies, could be a game changer for the shipping industry.
Hitachi Zosen
Hitachi Zosen is a licensee of the German company MAN Diesel & Turbo; the worlds leading marine engine provider. In October 2011, Hitachi Zosen commissioned the first vessel equipped with Selective Catalytic Reduction (SCR) by adapting NOx removal catalysts for industrial plants.
The Hitachi Zosen SCR is compliant with Tier III NOx emission standards: The third level (tier) of controls set by the IMO, which requires an 80% reduction in NOx emissions from operating marine vessels compared to Tier I standards. (5)
Hitachi Zosen received it’s first orders from a major Chinese manufacturer of large marine diesel engines, Dalian Marine Diesel Co., Ltd., for two units of a high-pressure selective catalytic reduction (SCR) systems. (5)
DAIHATSU DIESEL
Daihatsu have embraced the need for the shipping Co2 emissions reductions in a variety of ways. They offer SCR but also a range of clean burning dual fuel DF engines. The Daihatsu DF engines, switch seamlessly between gas & liquid fuel &, unlike a conventional diesel engine, can cut NOx by up to 80% during gas mode operation. (6)
Looking at the technologies Hitachi & Daihatsu are already utilising in their shipping portfolios, one can see the natural application for the Dolphin N2 CryoPower split cycle engine technology.
What makes the Dolphin N2 CryoPower split cycle engine design so unique?
The split design means that the hot and cold cylinders can be independently thermally insulated. The cold cylinder is maintained at relatively low temperature by the addition of liquid Nitrogen and this means that the compression is near isothermal. The hot cylinder is where the fuel is oxidised with minimal heat loss to the cylinder wall. This optimisation of compression and expansion creates a significant efficiency benefit over standard Diesel engine but it also allows a further energy saving, by transferring energy from the exhaust to the inlet air, thereby saving fuel energy.
Clearly, a ship the size of MV CSCL Globe , which was the largest shipping container in the world requires commensurate engine power and it’s two-stroke engine is rated at 69,720 kW @ 84 rpm & stands a whopping 17.2 meters tall’ (7).
Cryopower has the potential to reduce the Diesel/HFO use by as much as 30% * and when this is scaled to ship engine size it is clear that reduced engine out emissions is not the only benefit.
The Dolphin N2 CryoPower engine has the versatility, compatibility & applied capacity to ensure emissions are reduced by up to 90%, enabling it to bring emissions in line with the IMO targets of 50% reductions in Co2 for marine transportation by 2050.
The Dolphin N2 CryoPower engine is a real game changer for the engine industry, with multi layered applications, it has the capacity to make a direct global impact on climate change, by helping heavy haulage, marine, shipping & beyond reduce Co2 emissions to impact global temperature rises.
