• Spurred largely by pending global regulations, the race is on to develop low- and zero-carbon fuels for ships and scale up their use.
• There are “bridge fuels” that could be used during a transition period or in a limited way for the long term, such as biofuels, and then there are options that are more sustainable at scale, such as green methanol and green ammonia.
• Experts continue to debate the pros and cons of green methanol and green ammonia, which are generally seen as the best options in the medium to long term.
• A net-zero framework for shipping that would drive the adoption of alternative fuels is coming up for a vote in mid-October at a meeting of the International Maritime Organization in London.
