RIO DE JANEIRO, June 5 (Reuters) - Brazil's Eletrobras , Latin America's largest utility, has signed a memorandum of understanding with infrastructure company Prumo to produce green hydrogen in a port in Rio de Janeiro, which could lead to the development of a pilot plant, the two firms said.

The memorandum, signed on Wednesday at an event in Rio, also opens the door for studies on large-scale projects, the firms said. (Reporting by Leticia Fucuchima; Writing by Fabio Teixeira; Editing by Chris Reese)
