Developing next-generation energy, fuel, and data-center infrastructure with deep knowledge of Texas energy markets, industrial systems, and oil-and-gas operations.


Welcome to GreenDay Engineering — a Texas-based infrastructure development and engineering company focused on sustainable, energy-intensive projects. Our work began with sustainable aviation fuel and has expanded to include power-advantaged data-center development, where energy access, cooling strategy, land, and oilfield infrastructure knowledge are increasingly critical to project success.

At GreenDay Engineering, our mission is to develop practical infrastructure solutions that support the next generation of sustainable industry. We focus on projects where energy, technology, and industrial execution come together — including sustainable aviation fuel, onsite power strategies, and data-center infrastructure designed around efficient energy use, responsible water strategy, and long-term operational resilience.

The next generation of infrastructure will be shaped by access to reliable energy, efficient cooling, responsible water use, and strong project execution. GreenDay is focused on opportunities where industrial know-how can unlock cleaner fuels, lower-cost power, and more resilient facilities. From sustainable aviation fuel to AI-ready data centers, our work is built around practical solutions for large, complex energy demands.

Based in Houston Texas, a global hub of innovation & industry, our team is uniquely positioned to pursue complex infrastructure projects. Our team’s knowledge of the oil-and-gas sector, project development, energy systems, and industrial operations supports both our sustainable aviation fuel work and our evaluation of power-advantaged data-center opportunities.

GreenDay Engineering applies technology, engineering, and project-development discipline to infrastructure opportunities where energy efficiency and sustainability matter. In sustainable fuels, that includes SAF production pathways and related industrial systems. In data centers, that includes power strategy, cooling architecture, low-water design, and the potential integration of oilfield-adjacent infrastructure.
