NET Power and Lummus Sign Strategic Supplier Agreement for Heat Transfer Equipment

NET Power Inc. (NYSE: NPWR) (“NET Power”) announced today that it has signed a Strategic Supply Agreement with Lummus Technology to design and supply recuperative heat exchangers (“HXR”) for NET Power’s near-zero emissions power generation process. The HXR recovers energy from the turboexpander exhaust and air separation unit to reheat recirculated CO₂, making it one of the most important equipment components in the NET Power Cycle.

As the licensed NET Power HXR supplier, Lummus will provide HXR systems for NET Power’s utility-scale power plants. Upon completing the Project Permian Front-End Engineering Design (“FEED”), NET Power intends to issue a purchase order to Lummus for its first utility-scale power plant in Texas. Under the terms of the Strategic Supply Agreement, Lummus intends to leverage its global supply chain network to increase global HXR manufacturing capacity, enabling NET Power deployments at scale to help countries and communities around the world rapidly achieve their energy and environmental goals.

“This Strategic Supply Agreement marks an important milestone in implementing NET Power’s three-pillared strategy of proving our technology, building our backlog, and manufacturing for scale,” said Brian Allen, President and COO of NET Power. “Lummus’ expertise in licensed technology as well as designing equipment for proprietary processes makes them an ideal strategic supplier to enable NET Power to deliver the energy trifecta.”

Lummus has provided process industries worldwide with licensed technologies for more than 100 years. During that time, Lummus has designed and supplied more than 25,000 heat exchangers, including high pressure applications. The NET Power Cycle HXR leverages Lummus’ decades of experience in heat transfer equipment design and delivery for proprietary systems.

“Lummus is proud to partner with NET Power, which has developed a way to efficiently and effectively produce electricity that is clean, reliable and affordable,” said Leon de Bruyn, President and Chief Executive Officer, Lummus Technology. “The NET Power Cycle system combines seamlessly with our advanced heat exchanger technology. We look forward to working with NET Power to deliver low carbon power and helping them expand their offering worldwide.”
