Dairy Digester Enhancement Program
Clean Energy Fund (CEF)
The Dairy Digester Enhancement program (Program) is part of Clean Energy Fund (CEF) 4, funded from the 2019-21 biennial Capital Budget. This Program funds grants that enhance the viability of dairy digester projects, including bioenergy, improved energy efficiency, and advanced nutrient recovery systems that produce value-added biofertilizers, reduce trucking of lagoon water and improve soil health and air and water quality.
In May 2020 Commerce announced $970,000 in grants through a competitive application process. Awards included at least one project east of the Cascades and one project west of the Cascades.
Four proposed projects will address improved energy efficiency in operations and the marketing of biogas, nutrients, fiber and other co-products of the digesters. All of the grants for the proposed projects must be matched at least dollar-for-dollar with other sources of non-state funding.
- DeRuyter Dairies (Outlook, Yakima County): $164,145 to convert the DeRuyter Dairies from flush to flush flume to greatly reduce the volume of water mixed with manure and improve digester capacity, efficiency, and biogas production, as well as recovery of nutrients and fiber.
- Edaleen Cow Power (Lynden, Whatcom County): $300,000 to acquire new equipment (hydrogen sulfide scrubber) and infrastructure (new manure pipeline) at Edaleen Cow Power (ECP) to complete a new long-term offtake agreement and associated business plan. This plan can provide ECP and potentially other existing and new projects with higher-value power purchase agreements when the power for used for electric vehicles.
- FPE Renewables (Mt. Vernon, Skagit County): $300,000 to purchase and install a 10-20 wet ton/hour food residuals de-packaging system at a permitted material recovery and recycling facility for production and delivery of a new slurry feedstock stream for the FPE Renewables on-farm anaerobic digester, as well as other partnering digesters in Western Washington.
- Organix, Inc. (Outlook, Yakima County): $205,855 for a comprehensive pilot study to investigate the potential benefits of processing anaerobic digester effluent using the BioFiltro BIDA System. This system is anticipated to improve air quality by mitigating noxious odors and
