New UCL report claims $850bn of LNG-capable tonnage risks being stranded by 2030

UCL Energy Institute is a very influential research group. The UCL part is University College London. Their investigation of LNG-fueled vessels indicates that these ships are not on the best path to reduce carbon emissions. Thus, many of them being built now will need to be scrapped early.

A news piece written by the institute indicates as much as $850 billion of shipping may have to be scrapped.

The study could be quite influential. Shipowners have recently been investing in LNG-powered ships to produce reduced emissions now, especially since methane emissions are not being measured as they should. LNG ships emit methane, a worse greenhouse gas than CO2, through slip from the engine and the fuel handling operations. Most ships have not put in place advanced methane recovery systems.

The ships involved are dual-fuel ships that burn both oil and LNG, as well as single-fuel LNG powered ships.

The scientific evidence seems to indicate that LNG power may actually be worse than Low Sulphur Heavy Fuel Oil (LSHFO) when all the lifecycle emissions are analyzed. So the ultimate economic effect of the now LNG builds may turn out to be quite a waste of money.

The full report from the UCL Institute can be read here.

Supply chain decarbonisation needs partnerships to create a reaction

This discussion of a recent UNCTAD paper by Mikael Lind and Wolfgang Lehmacher sheds light on the complex problems facing shipping in the path to decarbonization. It spawned a whole chain of searches for me, to find out more about what some visionaries in the field are saying.

Admittedly seeing the future is fraught with risk. Scenario analysis gives one a sort of lay of the land. The article shows clearly how partnerships are essential since the problem is bigger than any one firm or country.

Read the article, and follow some of the links; you’ll be rewarded with a view of the problems the maritime industry faces to decarbonize.

IMO’s Carbon Intensity Indicator comes in for further criticism

A critique of the International Maritime Organization (IMO)’s new Carbon Intensity Indicator (CII) which comes into effect January 1, 2023.

The CII assigns a rating to ships based on their carbon efficiency. It takes into account their actual trips rather than just design. It also can change over time, as the ship encounters actual use and those measures are reported back.

For ships sailed by owners this is not so bad. But for chartered ships, the charter agreement could place the owner at a disadvantage, since the charter operator may use the vessel on routes or with sailing practices that reduce the measurements for the ship’s CII.

The article is interesting and quotes several commentators who think the problems will result in less sustainable shipping instead of more.
