Joaquim Leite Argues That Brazil Has Great Potential in Offshore Wind Energy Production, One of the Cheapest in the World

The Minister of Environment, Joaquim Leite, discussed, in an interview with CNN, the investment opportunities in sustainable technologies for energy generation in Brazil – since the country has great renewable potential. According to him, the country has great potential in offshore wind energy production (at sea), due to its natural characteristics of having a coastline with constant winds but without major storms. Thus, Brazil has the opportunity to generate a 100% clean energy source, which is also one of the cheapest in the world.

Joaquim also highlights that this energy can be transformed into hydrogen – the fuel of the future – and, therefore, exported to countries like Germany, which needs to replace its energy source.

According to the minister’s assessment, investment in the area will reduce energy generation costs in Brazil. He states that the country already has a record of 21 gigawatts of onshore wind energy, and, regarding solar energy, 14 gigawatts. According to Leite, solar is a great example of energy production in a decentralized manner, where costs are reduced.

What is Green Hydrogen?

Hydrogen gas has great energy potential, being used in sectors where decarbonization does not rely on other renewable energy sources, such as wind and solar energy. However, currently, the gas is still produced using non-renewable and polluting energy sources.

From this perspective, there is the possibility of increasing the use of renewable sources for this production, thus generating what is called green hydrogen. It has utility in various distinct areas, from transport to industry, being considered the “energy of the future.”

According to experts, the high cost still hinders its dissemination; however, in the coming years, this scenario is expected to change, with Brazil having excellent conditions to benefit from the new trend.

Although hydrogen is the most abundant chemical element in nature, it is also one of the most reactive. Thus, it is rare to find it alone, as it normally forms part of the components of other substances, such as various gases and water.

For the formation of green hydrogen, water molecules are separated through a process called electrolysis, which consists of passing an electric current through the water, responsible for separating hydrogen and oxygen atoms. Thus, two different gases are generated.

Among the advantages of green hydrogen, it can be mentioned that it is not intermittent or dependent on weather, like wind, solar, and hydropower sources. Moreover, it can be utilized in sectors where the application of other renewable energies would not be sufficient to meet all emission reduction needs, as well as in its production, surplus generated by other sources, which have no use, can be utilized.

About Offshore Wind Energy

Offshore wind energy is produced by harnessing the wind power that blows over the ocean, where it can reach higher and more constant speeds, thanks to the absence of barriers. It is a clean and renewable energy source.

Offshore wind farms are installed in relatively shallow waters, located away from the coast. To fully explore this resource, mega structures are built on the seabed, equipped with the latest technical innovations.

Although offshore wind energy is more common in Europe and Asia, it is beginning to be developed in Brazil, with requests for authorization for offshore wind farms and a federal government decree allowing this type of operation.
