Höegh Autoliners Taps BYD Battery Technology for Ammonia-Powered Car Carrier

Höegh Autoliners has signed an agreement with Chinese battery manufacturer BYD to install a marine battery system aboard its upcoming Aurora No. 12 car carrier, combining battery storage, solar panels and a shaft generator with ammonia propulsion.

The agreement, signed Monday at the COP31 climate conference in Antalya, Turkey, will see the vessel equipped with an integrated energy system designed to reduce fuel consumption and emissions. Scheduled for delivery in May 2028, Aurora No. 12 will be capable of operating on ammonia from the day it leaves the shipyard.

Höegh says the ship will be the first deep-sea car carrier to combine all four technologies, making it the most fuel-efficient pure car and truck carrier (PCTC) ever built.

“This shows that shipping can take the lead in the green transition. We are combining every green technology available on one vessel capable of running on ammonia from day one. Nobody has done that on a deep-sea car carrier before,” said Höegh Autoliners CEO Andreas Enger.
