RIO DE JANEIRO (Jan 13): US-based New Fortress Energy Inc said on Wednesday that it would buy natural gas company Hygo Energy Transition Ltd for US$2.18 billion to expand its presence in Brazil, a frontier for growth in the burgeoning liquefied natural gas market. New Fortress, an energy infrastructure company, is among the private industry players setting their sights on Brazil, where demand for super-cooled LNG is rising, though the market is smaller than in India and China, where power generators are shifting from dirtier coal to natural gas.
