LNG, Biofuels and the Future of Maritime Transport
Maritime shipping is a notoriously tricky sector to decarbonize, yet options for a greener industry are slowly emerging. Bio-LNG is helping clean up fuel tanks. New ship-building and navigational techniques, from advanced hull coatings to smarter routing, are making a dent in emissions. And new European rules are pushing ship owners toward cleaner options. Yet with a myriad of competing incentives – and no global consensus – how far can alternative fuels and efficiency gains really take maritime shipping on its long road to decarbonization? On today’s show, Tom Rowlands-Rees speaks with Fauziah Marzuki, BloombergNEF’s global head of gas, and Nikolas Soulopoulos, BNEF’s head of commercial transport. Together they discuss some of their teams’ research, including “Marine Fuel Costs to 2040 – Oil to Biofuels and Beyond” and “Global Shipping’s Net-Zero Framework Delay a Worst Option: React.” Complementary BNEF research on the trends driving the transition to a lower-carbon economy can be found at BNEF<GO> on the Bloomberg Terminal or on bnef.com Links to research notes from this episode: Marine Fuel Costs to 2040 - Oil to Biofuels and Beyond - https://www.bnef.com/insights/37781 Global Shipping’s Net-Zero Framework Delay a Worst Option: React - https://www.bnef.com/analyst-reactions/t4ac8igoymtc00 See omnystudio.com/listener for privacy information.
