Greenlane’s Latest News
Greenlane Renewables Files Patent Applications for New Landfill Gas Upgrading Technology Architected To Maximize Methane Recovery While Minimizing Capex
On December 9th, Greenlane announced that it has filed two new patent applications for landfill gas upgrading technology. The Company intends to bring to market in 2025 a new compelling product line that incorporates the content of these patent applications architected to advance the state-of-the-art in the production of renewable natural gas (“RNG”) from landfills by maximizing methane recovery performance while minimizing capital expenditure. Higher performance and lower cost systems enable RNG developers and project owners to enhance revenue generating RNG output from their assets while minimizing upfront investment, making RNG projects more accessible and scalable.
“Greenlane has been a pioneer in the RNG industry for over 35 years successfully opening up new markets and segments,” said Brad Douville, CEO of Greenlane. “Greenlane is also unique in the industry being the only biogas upgrading company offering and deploying systems utilizing the three main upgrading technologies: waterwash, pressure swing adsorption, and membrane separation, independently and in combination, plus proprietary biogas desulfurization technology. It is this deep level of understanding, unbiased perspective on technology and segment-specific insights gained through extensive experience that led to the development of this new intellectual property that addresses tough industry challenges.”

Greenlane’s Product Insights
Cascade H2O: Removing CO2 and Impurities from Biogas
Greenlane excels in water-wash technology, the leading biogas upgrading method used globally. This process uses counter-flow water to remove impurities without chemicals or heat. Raw, untreated biogas undergoes hydrogen sulfide removal, then is compressed, and flows through a water cascade, where carbon dioxide, any remaining hydrogen sulfide, volatile organic compounds, and siloxanes dissolve. The biomethane remains and is then dehydrated to produce dry renewable natural gas (RNG), while the water is purified and reused in a closed loop. Greenlane offers five high-efficiency models with modular designs to accommodate various flow rates, and larger capacities are achieved by using multiple systems in parallel.

Industry News
A Good Year For RNG
The Coalition for Renewable Natural Gas (RNG), in association with Guidehouse, released the findings of its 2024 Renewable Natural Gas Economic Impact Analysis at its annual RNG conference in December. As of 2024, more than 400 RNG facilities were operational at landfills and anaerobic digestion plants, with an additional 130 under construction and 233 planned.
“Together, these planned projects represent a 60% potential increase in production capacity,” notes the analysis. “From facility construction to ongoing operations, RNG projects contributed nearly $14 billion in total economic activity, benefiting supply chains and local economies alike. Further, RNG facilities and operations generated $7.2 billion in Gross Domestic Product (GDP), and directly and indirectly sustained over 55,000 jobs in 2024, creating meaningful employment opportunities in diverse communities nationwide.”
Biogas Investment Tax Credit Finalized with Favorable Language for RNG
The Internal Revenue Service finalized language on Wednesday for several investment tax credits for clean energy, including biogas. The updated language is more favorable to renewable natural gas projects that refine biogas from landfills or organic waste than an earlier draft, according to industry groups.
Proposed language for the credit released in November 2023 drew criticism from industry voices over wording that appeared to exclude certain portions of facilities that upgrade biogas into RNG. Groups like the American Biogas Council and Coalition for Renewable Natural Gas spoke out against the draft rule.
The final update is “good news” for RNG developers, the American Biogas Council said in a press release. RNG developers that began projects this year are expected to apply for the credit.
RNG contributed $7.2B to US GDP in 2024 According to Industry Report
In California, the Coalition for Renewable Natural Gas announced the findings of its 2024 Renewable Natural Gas Economic Impact Analysis, underscoring the renewable natural gas (RNG) industry’s remarkable contributions to the U.S. economy.
The 2024 Economic Impact Analysis, prepared by Guidehouse, highlights the broad benefits of RNG across the energy, environmental, and economic sectors. Released in conjunction with RNG Coalition’s annual RNG CONFERENCE event in Dana Point, California, the report reinforces RNG’s potential to scale up as a clean, flexible energy source that supports the nation’s alternative energy ambitions while generating tangible value for households, businesses, and municipalities.
American Biogas Council Captures Greenlane’s Announcement on Patent Applications for New Landfill Gas Upgrading Technology
As captured by the American Biogas Council news stream, Greenlane recently announced that it has filed two new patent applications for landfill gas upgrading technology. The Company intends to bring to market in 2025 a new compelling product line that incorporates the content of these patent applications architected to advance the state-of-the-art in the production of renewable natural gas (“RNG”) from landfills by maximizing methane recovery performance while minimizing capital expenditure. Higher performance and lower cost systems enable RNG developers and project owners to enhance revenue generating RNG output from their assets while minimizing upfront investment, making RNG projects more accessible and scalable.
U.S. EPA: 2.03 billion RINs generated under RFS in November
The U.S. EPA on Dec. 19 released data showing that 2.03 billion renewable identification numbers (RINs) were generated under the Renewable Fuel Standard in November, up from 2.01 billion generated during the same month of last year. Nearly 22.9 billion RINs were generated during the first 11 months of 2024, up from 21.59 billion generated during the same period of 2023.
Nearly 88.94 million D3 cellulosic biofuel RINs were generated in November, including 72.75 million generated for compressed renewable natural gas (RNG) by domestic producers, 6.76 million generated for cellulosic ethanol by domestic producers, 5.3 million generated for liquefied RNG by domestic producers, 1.99 million generated for liquefied RNG by importers, 1.93 million generated for compressed RNG by domestic producers, and 212,171 generated for RNG by domestic producers.
European Biogas Association Report: Renewable Gas Tracking Systems – Value of biomethane/RNG certificates
A new analysis by S&P Global Commodity Insights and supported by EBA, ERGaR, Eurogas and the RNG Coalition, provides valuable input to the ongoing revision process of the GHG Protocol. The use of certificates will be critical to meet the increasing sustainable biomethane demand from the private sectors, support the economics of new production capacities and ultimately contribute to climate change mitigation efforts.
