TOKYO -- U.S. hydrogen fuel cell maker Plug Power, which counts Walmart and Amazon as its clients, is planning to expand its businesses in China, Vietnam and South Korea, through a joint venture with conglomerate SK Group.
Earlier this year, South Korea's SK made a $1.6 billion investment in the Nasdaq-listed company. Through the joint venture, the two companies are planning to set up a factory in South Korea by 2023 to produce fuel cells and electrolyzers that extract "green hydrogen" from water using renewable energy.
