Norwegian shipping firm Hoegh Autoliners will install marine battery systems supplied by China's BYD on its upcoming ammonia-fuelled car carrier Aurora No. 12.

The companies signed a strategic and technical cooperation agreement to integrate BYD's battery technology with the vessel's existing energy systems, according to a emailed press release.

The ship will combine ammonia fuel, batteries, a shaft generator and solar panels, making it the first deep-sea car carrier to bring together these technologies, according to Hoegh Autoliners.

The integrated system is expected to reduce greenhouse gas emissions by around 1,000 tonnes of CO2 equivalent annually while improving fuel efficiency.

Scheduled for delivery in May 2028, Aurora No. 12 will be part of the company's Aurora class, which can carry up to 9,100 cars and is designed to cut carbon emissions by up to 58% compared with conventional-fuelled pure car and truck carriers.
