Deploying our proven energy infrastructure project development expertise and leveraging off our completion of the world’s largest anaerobic co-digestion project, RNG Energy is continuing development of large urban anaerobic digesters that produce renewable natural gas and manage large volumes of diverted organic waste while supporting regional sustainability goals.

Our Mission

Our stated mission is to deploy our proven development expertise towards the successful development of large-scale anaerobic digester projects for the production of sustainable and renewable natural gas.

Who We Are

RNG Energy Solutions, LLC (RNG) develops, finances, owns, and manages the operations of state-of-the-art anaerobic digester projects that produce renewable natural gas. As the successor company to AgEnergy USA, RNG brings three decades of conventional and alternative energy development experience in the agricultural, urban, and industrial environments. Most notably, AgEnergy USA completed the development of the Heartland Renewable Energy project, which is the largest co-digestion anaerobic digester project in the world.

RNG Energy Solutions’ predecessor company, AgEnergy USA, LLC, was founded in 2010 to provide industry leading technology and project development capability to generate renewable energy from organic waste streams by developing, financing, constructing, owning, and operating anaerobic digester (AD) projects in North America. AgEnergy was the developer and was a net profit interest owner of the Heartland Biogas LLC Project. More recently, we managed the acquisition of Heartland Biogas and changed the Project name to Platte River Biogas, LLC. We are now managing the next phase of financing the incremental capital requirements of the Project and proceeding with minor modifications and re-starting as a manure only digester. Platte River recently secured its required Use by Special Review permit from Weld County. We will be managing the construction of the improvements, the Start-Up and Commissioning and Asset Management Phase of the Project.

The RNG Energy team has over 100 combined years of related industry experience. Our work developing complex energy infrastructure projects includes permitting, preliminary design, financing, construction management and operations.

What We Do

All of the projects completed by RNG Energy Solutions personnel incorporated first time applications of environmental control technologies and commercial/contractual solutions resulting in energy projects being completed in high barrier to entry markets. The fast track projects on Long Island were developed and constructed in record time. As an example, RNG Energy personnel secured the permits, financed and released for construction the 80MW Pinelawn Power Combined Cycle Project in 10 months. As another example, AgEnergy secured all the permits for the unique and complex Heartland Renewable Energy Project in 8 months. Construction on this first of its kind project was initiated 30 days thereafter.

LINDEN RENEWABLE ENERGY, LLC

(see the link below for a virtual tour of the Facility)

The Linden Renewable Energy Project (LRE) an urban organic waste anaerobic digester (AD) facility. The facility will digest source separated organics (SSO) and fats, oils, and grease (FOG) to produce pipeline quality renewable natural gas (RNG). The facility will include feedstock receipt facilities for unloading tanker trucks and barges; feedstock de-gritting, storage, and pretreatment systems; and anaerobic digestion in eight steel tanks, each 1,567,000 gallons. Biogas produced in the digesters will flow into a Biogas Upgrading System (BUS) that includes biogas storage in an inflatable dual-membrane structure; a carbon bed to remove hydrogen sulfide; and a three-stage membrane system to remove carbon dioxide and other contaminants to meet natural gas pipeline quality standards. The Digester effluent will be treated by a multistep process that includes a filter screen to remove the plastics that were not removed in the pre-digestion grit removal process; a centrifuge to remove finer solids; and a Membrane Bioreactor (MBR) system for filtration and conversion of ammonia nitrogen to nitrate and of organics to carbon dioxide and water. The solids fraction produced by the centrifuge will be a commercial grade product (similar to finished compost) for use as soil amendment. The treated water from the MBR will meet Linden Roselle Sewerage Authority (LRSA) discharge requirements.

A unique aspect of the Project is that fuel cells provided by Bloom Energy will be the primary source of power for the Project. The Bloom Energy fuel cells will reduce the Project’s carbon emissions relative to utility power, and will eliminate emissions of NOx, SOx, and other pollutants associated with fossil fuel-fired power generation. The Project will also be connected to the electric grid for a redundant 100% power supply.

As the project owner, Linden Renewable Energy, LLC has contracted with two world-class firms to construct and operate the Project. At the time of Project financial close, LRE will be owned by an affiliate of Starwood Energy (“Starwood”) and by principals of RNG Energy Solutions, LLC. The Project was developed by RNG Energy Solutions, LLC (the “Developer”). RNG Energy specializes in the development, financing, operation, and management of complex energy infrastructure projects including anaerobic digester projects.

PLATTE RIVER BIOGAS (FORMERLY) THE HEARTLAND PROJECT

Heartland was an anaerobic digester project using dairy manure and organic waste substrate in a high ratio, complete mix, co-digestion system. The Project includes 6, 1.7 MG bio-reactors, Biogas Upgrading System, gas compression and pipeline interconnection to Colorado Interstate Gas company (CIG) pipeline.

Recently, AgEnergy managed the acquisition of the now Platte River Biogas, LLC project and is proceeding with managing multiple new project phases including,

  • Re-permitting
  • Financing
  • Construction Management
  • Start-up and commissioning and
  • Asset Management

The new Platte River Project will be owned by a consortium of regional dairy’s who have committed their manure feedstock to the Project.

  • Heartland (now Platte River Biogas) was the largest co-digestion anaerobic digester project in the world.
  • Heartland ahs been acquired and the new Project, Platte River Biogas, LLC will operate on manure feedstock only. The new owners are three large dairy’s located in Weld County.
  • Raw biogas is upgraded to pipeline quality gas via two separate Greenland Totara plus wet scrubbers rated at 1,600 (each) dktherms per day.

Project_Image

  • The Platte River Biogas Project will produce 14,500 dktherms per day of pipeline quality Renewable Natural Gas (RNG).
  • The RNG will be produced from 500,000 gallons per day of regionally secured manure feedstock.
  • The Project will also produce roughly 260 cu yrds per day of high value digested solids

Project_Image

  • Platte River provides a sustainable and long term solution to manure management.
  • The RNG will be used as a CNG transportation fuel resulting in major carbon reduction benefits.
  • The Project upgrades includes a liquid digestate management system that produces over an acre foot per day of clean water, a valuable commodity in Northern Colorado.

Long Island Projects

AD Project Experience

James Potter developed his early understanding of co-digestion anaerobic digesters as former President of Homeland Renewable Energy (HRE). The HRE team acquired the following three projects in Wisconsin and managed the operations including substrate procurement and supply. These Projects were early innovators in the AD space in North America. HRE successfully operated the projects in the thermophilic mode for several years and consistently outperformed the original gas production analyses.
