About Pure-Green
Where Leadership, Technology and Execution Align
Building Tomorrow’s Energy Infrastructure
We’re a team of innovators, educators and energy veterans tackling the world’s toughest energy challenges. Our expertise spans subsurface engineering, mechanical systems and strategic finance – a combination that’s hard to find anywhere else.
We specialize in connecting conventional energy knowledge with emerging renewable thermal technologies. Our team includes PhDs, university professors and fellows from leading engineering organizations who don’t just use technology, they create it.
Our Expertise
Our strength comes from deep knowledge across multiple disciplines:
Engineering & Design: Licensed Professional Engineers across multiple states with expertise in mechanical systems, well construction and geothermal loop design.
Subsurface Science: Master Geoscientists and PhDs conducting leading research in rock mechanics, reservoir systems and heat recovery, including work on the Frontier Observatory for Research in Geothermal Energy (FORGE).
Academic & Industry Leadership: University professors and fellows from AEE and ARMA advancing the field through research and education.
Business & Strategy: Wharton MBAs, finance professionals, and real estate experts who ensure our technical solutions make economic sense.
Proven Results at Scale
We’ve delivered major projects measured in millions: square feet served, vertical drilling completed and capital invested.
Geothermal Leadership: Our team has designed and installed over 5,000 wells worldwide, managed more than 100,000 MW of heat pump equivalent capacity, and built campus-wide thermal systems serving millions of square feet.
Oil & Gas Background: We bring decades of senior-level experience from global companies like Shell, where we’ve overseen billion-dollar budgets and led large teams on critical energy infrastructure projects.
Innovation Track Record: With 220 combined patents, our experts have developed steerable motors, expandable casing, advanced wellbore process models and more.
Environmental Recognition: Our commitment to responsible resource development has earned us honors including the National Award for Excellence in Surface Coal Mining and Reclamation from the U.S. Department of Interior.
Our Approach
The shift to sustainable energy demands more than ambition, it requires technical excellence. Whether we’re simulating hydraulic fractures, designing high-efficiency thermal systems for multi-building campuses or managing global well technology programs, we apply rigorous, evidence-based methods to every challenge.
We combine four decades of field-proven experience with cutting-edge computational modeling to build energy systems that are resilient, efficient and ready for today’s demands.
