The snake and armadillo-filled scrublands of Northeastern Brazil’s Serra da Babilonia, or Hills of Babylon, are as stunning as a first-rate national park. It’s here where renewable energy is transforming Brazil, and where the country’s green hydrogen economy is getting off the ground.

Wind developer Casa dos Ventos just installed 80 turbines. The towers churn out enough power for a small city, but that’s not where it’s going. The main buyer is chemicals producer Unigel, which will use it to split water molecules and make hydrogen at a port on coast of the state of Bahia.

"We see Brazil as a leader in the green hydrogen economy for one main reason: the availability of renewable energy,” said Unigel Executive Director Luiz Felipe Fustaino.
