The Port of Açu, in São João da Barra, aims to attract around R$ 22 billion in investments over the next ten years, with green hydrogen, data centers, and a hub for decommissioning platforms sharing space in a complex that already handles minerals and oil.
This figure was presented on September 2 by Eugenio Figueiredo, the port’s president. He was keen to clarify the source of the funding: the vast majority comes from investments made by clients, the companies established within the complex.
This is the logic of the model. The Port of Açu is not just a dock; it is an industrial district with access to the sea, where the operator sells land, infrastructure, and logistical connections, while tenants build their facilities.
What the port already handles today
Before looking at the future R$ 22 billion, it is worth measuring the existing installed capacity. According to the data presented, the ore terminal has a capacity of 26.5 million tons per year and currently operates around 24 million tons.
The oil terminal handles up to 1.8 million barrels per day. Meanwhile, the Multi-Cargo Terminal operates between 2.7 and 2.8 million tons annually.
One often-overlooked fact that explains much of Brazil’s economic geography is that about 50% of the Multi-Cargo Terminal’s traffic has origins or destinations in Minas Gerais. A landlocked state, it thus accounts for half the traffic at that terminal located in Rio de Janeiro.


This positions Açu as the Atlantic outlet for the mining quadrilateral, competing for cargo with Vitória and Santos. This is why the port frequently appears in discussions about logistics for ore and steel.
Three distinct bets on the same land
The portfolio for the next ten years is not just a continuation of what’s existing. It points towards sectors that are not yet the backbone of the complex.
The first bet is on green fuels, with the production of hydrogen, green ammonia, sustainable aviation fuel, and e-methanol. These are products that require cheap and abundant renewable energy, along with a port capable of exporting whatever is produced.
The second is data centers. This may seem out of place in a port, but it’s not: these installations require a large volume of steady energy, ample land, and connectivity, and Açu has thermal generation within the complex.


The third bet is the one that most closely aligns with the Brazilian oil industry: a hub for decommissioning and recycling of offshore units. The country has dozens of platforms nearing the end of their useful life, and currently much of this service is done outside Brazil or in an improvised manner.
In addition, there are expansions in mining, oil and gas, and renewable energy projects, as well as what the operator refers to as low-carbon industrialization.
What separates the portfolio from reality
The announcement of a ten-year portfolio is always a conditional promise. As the executive pointed out, almost all of the value depends on third-party investment decisions, not on the port’s cash flow.
Each of these projects has its own barriers. Green hydrogen depends on a sales contract abroad and competitive energy costs. The data center relies on guaranteed electricity supply and tax regulations, an issue that has only recently begun to be addressed in Congress.
Decommissioning depends on contracts with operators and specific environmental licensing, as dismantling platforms involves hazardous waste and contaminated structures.


Thus viewed, the full value functions more as a market signal than as a prediction. It is the operator indicating which sectors it intends to sell land in the next decade.
Still, Açu has something that most Brazilian infrastructure projects lack: it already exists, is operational, and is handling a significant volume. The discussion is not about building a port from scratch, but rather about what to install alongside what already works.
For the northern Fluminense region, which has seen oil activities shift to other bases in recent years, this model carries weight. Decommissioning and green fuel are chains that provide jobs on land, in the industrial yard, and not only on board.
The number to watch is not R$ 22 billion. It’s how many final investment decisions come to fruition in the next twenty-four months, because that’s what separates announced portfolios from active construction sites.
It’s worth understanding how Açu got here, because the trajectory explains the model. The complex originated from a private project conceived in the last decade, navigated the crisis of the group that envisioned it, and was reorganized under new ownership.
What survived this journey was the physical asset: a deep-water port on a large piece of land, with licensing already expired and installed infrastructure. In Brazilian infrastructure, this is rare.
Precisely for this reason, the operator can sell speed. A company that decides to install a plant there doesn’t start the licensing process over nor does it build maritime access, and this shortening of timeline is part of the product.
There is also the energy issue, which supports a significant part of the portfolio. The complex houses operational gas thermal generation, and reliable energy on-site is a prerequisite for both the data center and hydrogen electrolysis.
Without this, neither of the two bets make sense financially.
On the other hand, concentrating such diverse sectors in the same space creates internal competition for energy, area, and logistical connections. Defining who enters first, and with what supply guarantee, is a decision that the operator will have to make in the coming years.
Additionally, it’s worth measuring the announcement against what has already been delivered. According to the operator, the complex was brought to its current scale in just over a decade, which lends some credibility to the proposed timeline.
However, the sectors in the new portfolio are much more dependent on public policy than minerals and oil. Green fuel needs a regulated market abroad; data centers require defined tax regimes; decommissioning needs clear environmental regulations.
Thus, the ten-year timeline depends less on the port and more on decisions made in Brasília and Brussels. During this period, therefore, the key indicator is not the announced value, but the number of lease contracts actually signed within the complex.
Would you bet on green hydrogen, data centers, or decommissioning as the business that will really take off at Açu?
