EFECamaçari, Brazil

Brazilian chemical giant Unigel broke ground here Tuesday on what will be - if only for a few years - the world's largest facility to produce green hydrogen, defined as hydrogen generated using renewable or low-carbon energy.

Unigel is investing $120 million in the facility, which will be integrated into the company's existing operations at the Camaçari Industrial Complex in the northeastern state of Bahia.

By the end of next year, the plant will begin turning out 10,000 tons of green hydrogen and 60,000 tons of green ammonia annually, Unigel said.
