Project Presented on Friday, 6, Introduced Energy Generation Through Water Flow, Thus Providing a 100% Oil and Gas Free Source
The city of Macaé, in Rio de Janeiro, has become a national reference in the development of energy production proposals, whether derived from oil and gas or from renewable sources. The city is now developing the energy generation project through horizontal water flow, which is being planned by the company John Cockerill. This project was presented on the 6th to the mayor of Macaé, Welberth Rezende, and to the secretaries of Economic Development, Rodrigo Vianna, and Environment, Juninho Luna.
The renewable energy production plant will be capable of generating approximately 2 megawatts of energy, however, the prototype still needs to go through the testing phase in January in the city of Macaé. The test has the authorization of INEA (State Institute of Environment).
According to the mayor of Macaé: “We are indeed the city that proposes discussions of projects that promote the energy transition, created by professionals and companies dedicated to innovation and sustainability. And the most important thing is that these turbines will be produced in Macaé, establishing a new profile for our economic development.”

Brazilian scientists are simultaneously advancing two research projects on clean hydrogen and driving solutions that could transform the energy matrix, enhance industrial competitiveness, and accelerate large-scale emission reduction targets.

Advancement in renewable energy: A R$ 150 million project launched by Petrobras and Finep aims to create state-of-the-art electrolyzers for green hydrogen, strengthening national research and preparing Brazil to compete in a billion-dollar energy market.

Illiterate or semi-literate grandmothers were trained to repair solar systems, open rural workshops, and light up homes that still depended on kerosene.

The world has bet on green hydrogen as the fuel of the future, but now faces the side effect: producing 1 kilogram requires about 9 liters of ultrapure water, and the largest projects on the planet are precisely in the driest regions of the Earth, where water is already scarce for people.
Biogas Plant in Macaé
Oil and Gas Free Plant
The project being developed for the city of Macaé, without using oil and gas, will produce 100% renewable energy and it is already being sought after by companies abroad in Africa and Portugal. During its assembly phase, the oil and gas free turbine will still include some parts manufactured in Belgium.
As Marcelo Amado, manager of John Cockerill’s Macaé unit states: “The partnership with the city hall is essential to make the production of this project feasible at our base in Macaé. We will start the testing phase this month and our expectation is that the turbines will be available on the market by December.”
The prototype presentation of the turbine also featured participation from Hudson Azevedo, commercial coordinator for the oil and gas segment at Sika.
