As the world grapples with the urgent challenge of reducing carbon
emissions, technologies like Carbon Capture, Utilization, and Storage (CCUS) have moved from the fringe to the forefront of the climate conversation.
This process, which involves capturing CO2 emissions and storing them
underground, is recognized by the
International Energy Agency
as a key enabler for achieving
net-zero goals. When you think of pioneers in this space, you might picture a nimble tech
startup or a renewable energy consortium.
But what if the world’s single largest operator of this critical climate
technology is a national oil company? In a counter-intuitive turn,
Brazil's Petrobras
has become a global force in CCUS, operating on a scale that dwarfs many
others. Here are five surprising and impactful facts about their
pioneering work in capturing carbon.
1. The Sheer Scale is Mind-Boggling: They're the World's #1
Petrobras operates the world's largest Carbon Capture, Utilization, and
Storage program by annual reinjected volume. In 2022, the company reached
a record-breaking milestone, reinjecting 10.6 million tons of CO2.
To put that number in perspective, the
Global CCS Institute
reports that this single company's effort accounted for approximately 25%
of the total CO2 injected by the entire global industry that year. The
fact that a quarter of the world's carbon capture volume comes from one
entity is a staggering statistic, highlighting Petrobras's significant and
surprising role in the global effort to manage emissions.
2. It's a Two-for-One Deal: Capturing Carbon Actually Boosts Oil
Production
The genius of Petrobras's CCUS system is its counter-intuitive dual
benefit: reinjecting CO2 isn't just for storage; it's a critical component
of their production process. The technique, known as Enhanced Oil Recovery
(EOR), involves injecting the captured CO2 back into the deep-sea
pre-salt reservoirs
from which it came.
This process helps maintain the internal pressure of the reservoirs,
which in turn increases the amount of oil that can be extracted. This
innovation simultaneously prevents CO2 from being released into the
atmosphere and boosts production efficiency, resulting in oil with a
significantly lower carbon footprint. According to the company, its
pre-salt oil has CO2 emissions up to 70% lower than the world average,
creating a distinct competitive advantage.
"Consuming oil produced with lower emissions is an immediate and relevant
contribution to reducing global emissions. [...] The mastery of CCUS-EOR
technology is a lever to reduce the emissions of several sectors and an
element of competitiveness for the Petrobras."

3. They're Not New to the Game: A Decade of Deepwater Pioneering
This massive operation didn't spring up overnight. Petrobras has been
quietly building its CCUS capabilities for over a decade, with its first
implementation dating back to 2008. By 2022, the company had reinjected a
cumulative total of 40.8 million tons of CO2 and has set an ambitious goal
to reach a total of 80 million tons by 2025.
What makes this achievement even more remarkable is that Petrobras is a
pioneer in applying CCUS in the harsh and technically demanding
environment of ultra-deep waters. Today, all 21 of its production
platforms operating in the Santos Basin pre-salt fields are equipped with
this technology. This sustained leadership has earned continued
recognition. In 2015, the company received the prestigious
OTC Distinguished Achievement Award—often considered the "Oscar" of the offshore oil and gas industry—and
followed it with the
Firjan Sustainability Award
in 2020, proving their pioneering work wasn't a one-off achievement but a
sustained commitment to innovation.
4. The Next Frontier Isn't Oil Fields, It's the Seabed and Saline
Aquifers
Never content to rest on its laurels, Petrobras is already innovating
beyond its current methods to define the future of carbon storage. Two key
initiatives stand out. The first is its patented
HISEP (High Pressure Separation) technology, a system designed to separate gas and reinject CO2 directly on the
seabed. This innovation aims to reduce the weight, size, and cost of
processing units on platforms, further increasing efficiency.
The second is the "CCS São Tomé" pilot project, a landmark initiative for
Brazil. It will be the country's first project to capture CO2 and store it
in a
deep saline reservoir—a geological formation filled with brine—rather than an active oil
field. With a goal of capturing and storing 100,000 tons of CO2 per year,
the project is a strategic platform for developing future large-scale CCS
hubs and shaping national regulations.
"The CCS São Tomé Pilot Project is a strategic Research, Development and
Innovation (R&D) initiative that will allow us to validate, in a real
environment, fundamental technologies and methodologies for the
implementation of carbon capture and storage (CCS) hubs in Brazil."
5. They're Giving the Map Away: Free Data to Fuel a National Effort
In a move that underscores its commitment to advancing CCUS beyond its
own operations, Petrobras conceived, sponsored, and provided technical
oversight for the development of "GIS CCUS Brasil," a free, online platform designed to accelerate carbon capture projects
across the country.
The tool centralizes and shares essential public data, including the
location and emissions data for over 1,500 industrial CO2 sources, details
on existing infrastructure like gas pipelines, and in-depth analysis of
potential geological storage sites in Brazil's sedimentary basins. By
democratizing this critical information, Petrobras is providing a roadmap
for other industries to decarbonize their operations, extending the impact
of its expertise far beyond its own facilities.
Conclusion: An Unlikely Architect of a Lower-Carbon Future?
Through a combination of massive scale, innovative technology developed
over more than a decade, and a strategic vision for the future, Petrobras
has established itself as a surprising and globally significant leader in
Carbon Capture, Utilization, and Storage. The inherent paradox is that the
expertise required for large-scale carbon storage—deep geological
knowledge and massive offshore engineering—currently resides with the very
companies driving the need for it. Petrobras's work demonstrates how this
legacy expertise could be pivotal for the energy transition.
This raises a compelling question for the global community. As the world
seeks scalable climate solutions, could the engineering giants of the
traditional energy sector become the unlikely architects of a lower-carbon
future?
