Vancouver, WA – Host Bioenergy Systems North America and Bright Renewables North America have been selected to provide renewable natural gas (RNG) technology for Global NRG Renewables' distillery waste-to-renewable natural gas (RNG) project in Louisville, Kentucky. The project will convert 105 million gallons per year of distillery waste into high-quality RNG to be used for heat, electricity, transportation and the production of food-grade liquid bio-CO2.
HoSt, a specialist in Continuously Stirred Tank Reactor (CSTR) anaerobic digesters, will supply three primary and one secondary digesters with a capacity of 3 million gallons each. Bright will provide the biogas upgrading system with a capacity of 1400 SCFM (Standard Cubic Feet per Minute) and the CO2 liquefaction technology with a capacity of 600 SCFM. All biogas beneficiation technology will therefore be integrated and supplied by the HoSt Group, reducing project complexity and risk. Construction of the plant is expected to start in early 2025, with Swinerton Energy responsible for engineering, procurement, construction (EPC), as well as commissioning and project handover.
“We are excited to work with Global NRG Renewables on their first RNG project,” said Graham Hartlett, chief sales officer for HoSt Bio-Energy Systems NA. “With a proven track record of distillery projects in Europe, including the renowned Grolsch Brewery in the Netherlands, HoSt Group is well-positioned to bring this innovative solution to the U.S. market. With the trusted Swinerton Energy on board as the EPC, we are confident the project will be built on time and on budget.”
Chris Negus, CEO of Global NRG Renewables, added: “This project demonstrates our commitment to sustainability and innovation in the RNG sector. HoSt's anaerobic digestion technology and Bright's complete solution of reliable biogas upgrading and CO2 liquefaction systems will ensure high efficiency and high quality of RNG production.”
Global NRG Renewables selected HoSt Bio-Energy Systems and Bright Renewables due to their extensive expertise and track record of success in similar projects. This collaboration marks Global NRG Renewables' first project in the United States and sets a precedent for future sustainable energy initiatives in the region.
