HoSt Bio-Energy Systems North America will supply biogas, RNG and CO2 liquefaction technology for Global NRG Renewables’ Distillery Waste-to-RNG Project in Kentucky

28 August 2024
HoSt Bio-Energy Systems North America has been selected to provide biogas and Renewable Natural Gas (RNG) technologies for Global NRG Renewables’ distillery waste-to-RNG project in Louisville, Kentucky. The project will convert 105 million gallons per year of distillery waste into high-quality RNG, which can be used for heat, electricity, transportation, and the production of food-grade quality liquid bio-CO2.

Project Scope

HoSt, specialists in continuous stirred tank reactor (CSTR) anaerobic digesters, will supply three primary digesters and one secondary digester, each with a capacity of 3 million gallons. Additionally, we will provide the biogas upgrading system, with a capacity of 1400 SCFM (standard cubic feet per minute), and the CO2 liquefaction technology, which has a capacity of 600 SCFM. All the biogas beneficiation technologies will be integrated and supplied by the HoSt Group, reducing project complexity and risk. Construction of the plant is slated to begin in early 2025 with Swinerton Energy responsible for the engineering, procurement, and construction (EPC), as well as commissioning and project handover.

“We are thrilled to collaborate with Global NRG Renewables on their inaugural RNG project,” says Graham Hartlett, Chief Sales Officer at HoSt Bio-Energy Systems NA. “HoSt Group’s proven experience with distillery projects in Europe, including the renowned Grolsch Brewery in the Netherlands, positions us well to bring this innovative solution to the U.S. market. We are confident that with trusted Swinerton Energy as the EPC the project will be built on time and within budget.”

Global NRG Renewables

Global NRG Renewables selected HoSt Bio-Energy Systems for their extensive expertise and successful track record in similar projects. This collaboration marks Global NRG Renewables’ first project in the U.S., setting a precedent for future sustainable energy initiatives in the region. Additionally is Global NRG Renewables dedicated to building a Renewable Natural Gas platform across North America and Europe, with a strong focus on sustainability and innovation in the renewable energy sector.

“This project exemplifies our commitment to sustainability and innovation in the RNG space. The full solution of HoSt’s anaerobic digestion technologies and Bright’s reliable biogas upgrading and CO2 liquefaction systems will ensure high efficiency and quality of RNG production.”
