Decarbonisation is shipping’s white swan (I refer to the kind made popular by Nassim Nicholas Taleb), or rather, a bevy of little white swans if you will. Complete decarbonisation is inevitable; the only question now is when, not if. It is necessary for the industry to survive, and thrive in the world we will be living in. Vessels built in 2050 will be very different from the ones we build today. …

I’d like to believe that an apple did hit Newton on the head, and that led him to discovering gravity. The story is just more fun that way. But whether or not the apple actually fell on his head, according to the manuscript in the archives of the Royal Society, an apple definitely seems to have been involved. Newton’s Principia, explaining the phenomenon of gravity was first published in Latin in 1687. And it created quite a ruckus.

Now, over 300 years later, climate change is hitting us on the head in no uncertain terms, and gravity seems to be…


I regularly run into innovators and inventors who are interested in deploying their zero-carbon or energy optimisation/saving technologies in the shipping industry. These conversations usually end up being pitches for the alternative fuel in question, or the ‘macro’ merits of shipping’s decarbonisation. But what I, or any potential user of the technology (who ultimately needs to foot the bill), really want to understand are the technology’s capabilities, the inherent risks and challenges to implementation, and barriers (or not) to scale.

Over the last few years, I’ve analysed several technologies for their potential to decarbonise the shipping industry and made decisions…
