Monroe Sequestration Partners (MSP) Signs Agreement with Southern Energy to create path for Permanent CO2 Sequestration

Partnership Signals Breakthrough Collaboration in Carbon Removal and Sustainable Fuel Development for $1 Billion Clean Fuels Facility

STERLINGTON, LA, UNITED STATES, June 4, 2025 /-- Monroe Sequestration Partners, a premier carbon storage development company with deep expertise in industrial decarbonization, is proud to announce a strategic Collaboration Agreement with Southern Energy, a Wyoming-based developer of low-carbon fuels. Under this agreement, MSP will serve as the carbon sequestration provider for Southern Energy’s $1 billion biomass-to-methanol and sustainable aviation fuel (SAF) facility planned for Louisiana.

This collaboration represents a major milestone in exploring co-located clean fuel production and carbon removal infrastructure. MSP, will utilize its Class VI carbon sequestration site, expected to be operational in 2027, to permanently store CO2 captured from Southern Energy’s plant, targeted to begin production in 2028.

"This is a powerful alignment of technology, infrastructure, and purpose," said Adam Farris, CEO of Monroe Sequestration Partners. "We’re thrilled to work with Southern Energy—an innovator with bold, climate-forward goals. Together, we are laying the foundation for scalable, high-impact carbon solutions that transform sustainability into real economic value."

Monroe's Strengths: Platform for Carbon Solutions

Monroe Sequestration Partners was built to meet the growing demand for permanent, verifiable CO2 removal. With a strategically located Class VI storage site, a seasoned leadership team, and the backing of DevvStream’s carbon credit expertise, MSP offers a vertically integrated platform for emitters looking to decarbonize and generate value through environmental assets.

The collaboration with Southern Energy is a natural fit, combining MSP’s sequestration infrastructure with an innovative biomass-to-fuel process designed to serve global transportation markets.

Partnership Goals and Project Highlights

• Carbon Storage: MSP will provide permanent CO2 sequestration, aligning with both federal compliance frameworks (45Q) and voluntary carbon credit markets.
• Sustainable Fuel Production: Southern Energy will produce low-carbon methanol and SAF using syngas technology and biomass sourced from the Southern Wood Basket—the largest in North America.
• Carbon Credit Generation: The project will generate 45Q tax incentives and premium voluntary carbon credits, leveraging MSP’s robust infrastructure and DevvStream’s monetization channels.

"This partnership is exactly the kind of collaboration we envisioned when forming MSP—to connect strategic industrial emitters with carbon storage solutions that are both technically sound and commercially viable," Farris added. "Our work with Southern Energy represents a shared commitment to climate innovation, and we’re proud to be part of a project that will help define the future of low-carbon fuel."

Louisiana: A Prime Location for CCS Innovation

Louisiana is uniquely positioned to accelerate carbon capture and storage projects, being one of only four U.S. states with EPA-approved primacy over Class VI wells. This status allows MSP to fast-track project timelines, offering a critical regulatory advantage in a state already attracting billions in CCS investment.

"Louisiana is becoming the carbon capture capital of the U.S., and MSP is proud to be part of that transformation," said Farris. "Together with Southern Energy, we’re building resilient carbon infrastructure that supports long-term environmental, regulatory, and economic success."
