Sustainability
Building Energy Infrastructure Responsibly
MMEX designs its projects around current environmental standards and integrated carbon capture, rather than building to minimum requirements and addressing performance later.
Our Approach
Our Approach to Environmental Responsibility
MMEX takes a straightforward position on responsible development: build new, and current control technology can be deployed throughout.
Most existing U.S. energy infrastructure was built decades ago, with environmental performance grandfathered under the standards in place at the time. The control technologies available today are proven and commercially available. They simply were never required at those facilities.
Both MMEX projects are new construction. That means carbon capture designed into the plant layout from the first drawing rather than retrofitted onto a facility that was never laid out for it. It means current-standard emissions controls throughout. And it means process configurations selected for efficiency rather than inherited from decades of modification.
This is not a claim that energy infrastructure has no environmental footprint. It is a statement that if this infrastructure is going to be built, it should be built this way.
Responsible Infrastructure Development
Environmental performance addressed at the design stage rather than after construction.
Long-Term Thinking
Assets designed for operating lives measured in decades, with the standards that implies.
Environmental Stewardship
Current control technology applied throughout both facilities.
Innovation
Carbon capture and hydrogen integrated into conventional infrastructure.
Continuous Improvement
Design flexibility to incorporate advances as they mature commercially.
Accountability
Performance measured against permits, standards, and stated design targets.
Carbon Capture
Carbon Capture, Designed In
Both MMEX projects feature carbon capture built into the initial design. This matters: legacy facilities were laid out decades ago, making it nearly impossible to scale capture beyond a stack or two. By designing for it from day one, we achieve facility-wide scale. The refinery recovers roughly 905 tons of CO₂ from its furnace stacks per day, while the power project captures 1,130 tonnes per day during hydrogen production. All captured CO₂ is compressed and pipelined to Permian enhanced oil recovery operations, producing additional domestic oil.

Environmental Stewardship
Environmental Performance
Engineered for low-sulfur Permian crude, the refinery reduces emissions—roughly 95% less SO2 and about 80% lower CO2 per barrel than typical Gulf Coast refineries—while the power project builds capture directly into hydrogen production. Both hold secured water rights and are advancing permitting.
- Resource Efficiency: Process configurations selected to reduce energy consumption per unit of output.
- Responsible Land Use: Development on secured sites with established access and infrastructure.
- Regulatory Compliance: Permitting advancing through the Texas Commission on Environmental Quality.
- Environmental Monitoring: Ongoing measurement and reporting as required under operating permits.
- Modern Emissions Controls: Current-standard controls applied throughout both facilities rather than equipment grandfathered under older rules.
Technology
Technology & Innovation
The innovation lies in the assembly. We are bringing configurations not widely deployed to the Permian Basin: a modular, diesel-focused refinery with built-in capture, and hydrogen-fueled combined-cycle generation.
Modern Refining Technology
A streamlined configuration optimized for light sweet crude with internal hydrogen generation.
High-Efficiency Power Generation
Combined-cycle generation with an effective availability of approximately 97%.
Carbon Capture
Integrated at both facilities, with captured CO2 directed to enhanced oil recovery.
Hydrogen Integration
Natural gas reformed to low-carbon hydrogen, with hydrogen-capable generation equipment.
Modular Construction
Shop fabrication under controlled conditions, improving quality and compressing schedule.
Process Optimization
Configurations selected for efficiency rather than inherited from decades of modification.
Community Commitment
In the Community
Two industrial developments of this scale are permanent additions to Pecos County.
MMEX intends to be a good neighbor there through local hiring and workforce development, partnerships with area schools and technical programs, support for community organizations, and open communication with residents about what is being built and why.
Construction will draw on regional contractors and skilled trades. Operations will support permanent technical positions. Both facilities will contribute to the county tax base throughout their operating lives.
Future Initiatives
Areas Under Evaluation
MMEX continues to evaluate technologies and approaches that could improve efficiency and environmental performance across its platform.
These are areas of ongoing assessment rather than commitments to specific future projects.
- Expanded carbon capture capacity
- Hydrogen production and applications
- Energy efficiency improvements
- Infrastructure modernization
- Emerging capture and process technologies
- Continuous environmental improvement

Frequently Asked Questions
What does sustainability mean at MMEX?
It means designing environmental performance into projects rather than addressing it afterward. Both MMEX developments are new construction, which allows current control technology to be deployed throughout and carbon capture to be integrated into the plant layout from the design stage.
How does MMEX reduce environmental impact?
Through design decisions. At the refinery, matching the process configuration to light sweet crude reduces processing intensity and eliminates the need for a stand-alone hydrogen plant. At the power project, reforming natural gas into low-carbon hydrogen with integrated capture reduces emissions relative to conventional gas generation. Both capture CO2 and direct it to enhanced oil recovery.
What role does innovation play?
Every technology used is commercially proven. The innovation is in how those technologies are combined and where they are deployed, not in the technologies themselves.
How does MMEX engage with local communities?
Through local hiring, contractor and supplier relationships, workforce development, and direct communication with residents and local officials. As the projects advance, this work will be documented on the News page.
How is environmental responsibility managed?
It is addressed in design and carried through permitting, construction, and operation. Both projects are permitted through the Texas Commission on Environmental Quality and operate under the monitoring and reporting requirements those permits impose.
What future technologies is MMEX evaluating?
Expanded carbon capture, hydrogen applications, and efficiency improvements, among others. These are areas of evaluation rather than announced commitments.
