|The green transition of the shipping industry is accelerating, with shipowners beginning to invest in vessels technologically prepared to use alternative fuels such as ammonia and hydrogen.
Currently, Clarksons estimates, alternative fuel propulsion is present in 4.8% of the fleet in operation. In 2021 it was 3.7% and in 2017, 2.3%). Among the current orders, 43.8% of tonnage vessels are able to use alternative fuels. In 2021 they represented 28.2% of orders and in 2017, 10.4%.
LNG and other alternative fuels can be used in 4.5% of the fleet in operation and account for 44% of the order portfolio, Clarksons Research data shows. This is a record share in the order book.
To contextualize, in 2021, 31.5% of the tonnage of the buildings ordered were able to operate with alternative fuels (479 units), up from 211 orders in 2020 and 46 orders in 2016.
Of the current order book, 38.9% of the tonnage provide for the use of LNG (781 units), 2.2% lPG (86 units) and 4.3% of other alternative fuels (260 units — including methanol, 42; ethane,11; biofuels, 5; hydrogen, 12). Hybrid battery/propulsion totals 200 units.
There are now more than 320 lng-ready and 99 ordered ships. There are 130 ships ready for ammonia and six ordered for hydrogen.
The debuggers are now installed on more than 4,838 fleet ships (including pending retrofit), equivalent to 24.9% of the total tonnage. Although the retrofit activity of scummers decreased (September 2020: 120 per month; September 2022: 15 per month), use in new construction increased slightly in 2021. At least 60 units to be equipped with scoffs have been ordered in 2022 so far.
Energy-saving technologies (ESTs) have been installed on more than 5,550 ships, representing 24.5% of the fleet's tonnage: this includes propeller ducts, rudder bulbs, Flettner rotors, wind kites, air lubrication systems and others.
Industry bodies are calling for a well-adjusted approach to calculating alternative fuel emissions as a way to ensure that overall emission reduction targets are met. According to Clarksons, this has created the likelihood of regional divergences, such as EU vs. US.
