Ship owners may be able to avoid investing in new engines for new fuels, as nanotechnology emerges which allows vessels to slash emissions, while using existing bunker fuel supplies. While the industry will relish the monetary savings and hail the reduced sulfur emissions, if taken up, this technology will stunt the rate at which the maritime industry reaches climate targets. Daphne Technology has developed a new closed-loop nanotechnology-based scrubber, which will allow cargo ships to comply with new International Maritime Organization emission regulations, while still using Heavy Fuel Oil into the 2020s. Sea transportation accounts for 90% of the worlds international trade, and emissions are predicted to increase between 50% and 250% by 2050. Air pollution from international shipping is…
