China’s EV battery giants wade into shipbuilding to bolster Beijing’s dominance


China’s leading battery makers for electric cars – Contemporary Amperex Technology (CATL) and Gotion High-tech – are adding momentum to the country’s efforts to build new-energy vessels, with their latest products supplied to large ocean carriers amid an accelerated decarbonisation drive.

Chinese-made pure electric-powered container vessels were also set to extend Beijing’s lead over global rivals in shipbuilding, according to industry officials and analysts.

CATL, the world’s largest electric vehicle (EV) battery producer, announced recently that its self-developed pure electric vessel would sail the oceans in three years, reinforcing the company’s ambitions of building itself into a global new-energy powerhouse.

Gotion, backed by Volkswagen Group, said early this month that its battery packs had proved strong enough to power a ship with a loading capacity of 132 standard containers. The vessel, known as Puffer Fish Blue 01, developed by China’s Wuhu Shipyard and Sandianshui New Energy Technology, had been certified by the China Classification Society, a professional body for ship classification, it added.

“Their investment and efforts to build pure electric container vessels show China’s increasing influence in the global shipbuilding industry,” said Xiong Hao, assistant general ­manager at Shanghai Jump International Shipping. “It remains to be seen whether electric vessels will be widely accepted by global container liners.”

CATL, which holds a 38 per cent share of the global EV battery market this year, began developing the shipbuilding applications in 2017 and has since supplied batteries to 900 vessels, all operating in rivers.
