Greenlane files patent application for linear NRU

Mr. Brad Douville reports GREENLANE ADVANCES ITS NEXT-GENERATION LANDFILL GAS UPGRADING PLATFORM WITH NEW PATENT FILING FOR INNOVATIVE LINEAR NITROGEN REJECTION TECHNOLOGY Greenlane Renewables Inc. has filed a new patent application for a linear nitrogen rejection unit (NRU) as part of its Cascade LF product line, the company's next-generation landfill gas upgrading technology. The company revealed Cascade LF to customers last month and is quoting it now incorporating the linear NRU. The linear NRU enables Cascade LF to achieve even higher methane recovery performance at a lower cost. These improvements are made possible when this new intellectual property is combined with the improvements achieved through the company's other patent applications filed within the last 12 months. As such, the linear NRU builds upon the previously announced Cascade LF innovations, reinforcing the company's technology leadership in the production of biomethane or renewable natural gas (RNG). Higher performance and lower-cost systems enable RNG project developers and owners to enhance revenue generating RNG output from their assets while minimizing upfront investment, making RNG projects more accessible and scalable. "This patent filing marks another important milestone in our commitment to customer-focused innovation and relentless pursuit of improving the state-of-the-art of technology in our industry," said Brad Douville, chief executive officer of Greenlane. "We took direct input from our customers to make a great product even better -- pushing the boundaries of methane recovery while driving costs down further. Our goal continues to be to make meaningful technology enhancements that will set our customers up for success by giving them the tools they need to extract maximum value from their waste resources. We are now quoting our Cascade LF products incorporating the linear NRU, targeting the first system delivery before the end of 2026." Greenlane's linear NRU technology is based on equilibrium pressure swing adsorption (PSA) principles. Conventional equilibrium PSA NRUs use multiple adsorption beds and internal recycling of recompressed gas. Greenlane's innovation, incorporated into its linear NRU, is a step-wise gas enrichment process that eliminates wasteful internal gas recycling while also using fewer and smaller adsorption beds. The result is lower operating and capital costs and higher methane recovery. For landfill gas containing increasingly higher levels of nitrogen, Greenlane's modular product design employs additional adsorption beds plus compression in a staged configuration that preserves the linear approach and high methane recovery over the range. The best results are achieved when Cascade LF is paired with landfill well field monitoring and controls to maximize methane collection and minimize fugitive methane emissions and nitrogen levels in the landfill gas. "As landfill gas remains the largest and most technically challenging feedstock for RNG production, we continue to focus on developing solutions that make upgrading simpler, more reliable and more cost-effective -- all while increasing performance," added Mr. Douville. "Our linear NRU may also have applications beyond biogas, broadening the potential reach of our technology, reinforcing Greenlane's leadership in advancing real-world technologies that accelerate decarbonization."
