Huawei bolts into Japan with renewable power storage, chasing Tesla

Chinese and U.S. companies sell large units at 1/5 of Japanese prices

Batteries that store energy from renewable sources are considered key to the world's decarbonization efforts. 

TOKYO -- Huawei Technologies will begin selling large-scale battery systems for renewable energy storage in Japan in March, Nikkei has learned, seeking to tap growing demand as the nation transitions away from fossil fuels.

Huawei will buy small battery packs from manufacturers including Contemporary Amperex Technology (CATL). These will be bundled into shipping-container-sized units that can each store 2,000 kilowatt-hours of energy -- roughly 200 times as much as a standard home battery. Capacity can be adjusted based on the buyer's needs.
