Class society DNV GL has publish an up-to –date assessment of the most promising alternative marine fuels available today. The study is timely as the 2020 fuel sulfur cap is fast approaching and the IMO has just decided to aim for a 50 percent cut in shipping’s carbo emission.
The International Maritime Organization on October 27 announced it was going ahead with a global sulfur cap of 0.5% on marine fuels starting from January 1, 2020, ending years of uncertainty.
Under the terms of the IMO’s MARPOL Annex VI regulation, the 2020 date was “subject to a review, to be completed by 2018, as to the availability of the required fuel oil. Depending on the outcome of the review, this date could be deferred to 1 January 2025.”
Now that the 2020 date has been confirmed by the IMO, a sharply more regulated shipping emissions sector looms into view in the near term. The current global sulfur cap on bunker fuel is much less stringent at 3.5%.
The sharp, step change down to tighter sulfur specifications at sea will have knock-on effects throughout the global energy system, including on road fuels. The cost of the IMO’s regulatory change on the shipping industry is unknown, but every analyst expects it to be large. As well as shipping lines, the IMO’s decision will also impact refiners, crude producers, bunker suppliers, and emissions and air quality affecting the health of millions of people.
The Shipping Industry is leaving no stones unturned in order to contribute towards a greener marine environment. At both manufacturing and administrative levels, the maritime industry is taking advantage of the latest technologies to ensure that new ships contribute as low as possible to the global pollution.
Designing a Ship in present times has become a challenging task for now a ship has to be fully complied with new environmental rules and regulations. A few benchmark technologies have already been developed to reach the ultimate goal of building a “Green ship” which would not only comply with the new environmental rules and regulations but would also leave least possible carbon foot-prints.
