Revolutionizing Clean Energy: Rentricity's New Hydrogen Technology Patent

Lead the Charge in Clean Energy



In a significant advancement for sustainable energy and infrastructure, Rentricity Inc. has secured U.S. Patent No. 12,454,761, covering innovative technologies for hydrogen gas production from water distribution systems. This patent introduces HydroCosm®, marking a major milestone in the company's mission to transform water infrastructure into a dual-purpose system for both water supply and clean energy generation.

The Vision Behind the Innovation


For over a decade, Rentricity has been a front-runner in recapturing clean energy from existing water infrastructures. The patented technology enables decentralized hydrogen production directly within pressurized water networks, an innovative shift from solely generating renewable electricity. This newly issued patent extends Rentricity's commitment to its Flow-to-Wire™ initiative, where excess pressure from water systems is turned into renewable electricity. Now, the same pressure can be effectively utilized to produce hydrogen gas through integrated electrolysis.

Frank Zammataro, the president and founder of Rentricity, expressed enthusiasm about this pioneering development: "This patent represents the next evolution of water-energy integration. Our focus has been on energy recovery within the nation's water systems—and now, with this hydrogen innovation, we can help utilities directly participate in the clean energy economy."

Addressing Waste and Maximizing Utility


Traditional water systems often waste pressure by releasing it through valves, a process that not only dissipates potential energy but also impacts efficiency. Rentricity's systems capture this wasted energy and convert it into usable electricity via compact turbines. With the new technology, this same pressure is channeled into hydrogen production, providing utilities with a crucial component to drive clean energy.

The technology combines a turbine-generator setup with an electrolyzer, extracting hydrogen and oxygen from water under optimal conditions. The hydrogen produced can either be stored for on-site energy needs or distributed for a range of applications, from fuel cells to hydrogen-powered vehicles.

Partnership and Experience Fueling Innovation


Rentricity credits its recent advancements to collaborative experiences, such as the Colorado Cleantech Industry Association’s Energy Fellows Institute program. Zammataro's engagement with the National Renewable Energy Laboratory (NREL) allowed for direct exposure to cutting-edge hydrogen technologies, enhancing the company's innovative approaches.

"That fellowship experience solidified how our in-pipe pressure recovery systems could facilitate hydrogen production," explained Zammataro. His time at NREL inspired the vision of integrating clean water production with hydrogen energy generation, showcasing a forward-thinking model for sustainable urban environments.

A Flexible Solution for Diverse Needs


The hydrogen system offers flexibility, suitable for various scales, including small municipal operations and larger, grid-connected setups. Utilizing smart sensors and controllers, the system operates autonomously, ensuring safe and efficient hydrogen production while keeping the water supply consistent.

As utilities worldwide face increasing pressure to meet clean energy mandates, Rentricity's system positions them as pivotal players in the hydrogen market, aligning with global decarbonization efforts and enhancing the resilience of public infrastructures.

Conclusion: The Future of Energy and Water


This groundbreaking patent empowers Rentricity's vision of creating an interconnected network whereby water infrastructure serves dual purposes—delivering safe drinking water while simultaneously generating clean energy. Zammataro emphasizes, "Hydrogen is a key element of our clean energy future. Water systems, with their persistent pressure and flow, present an untouched opportunity for localized, clean hydrogen production."

The patent positions Rentricity not only as a leader in energy recovery but also as an advocate for sustainable urban development, demonstrating that the next step in combating climate change lies in harnessing the untapped potential of our water resources.
