Dairy Digester Enhancement Program
Clean Energy Fund (CEF)
The Dairy Digester Bioenergy Program is part of the Rural Clean Energy Innovation Grants Program. Of the $4.75 million allocated to Rural Clean Energy for the 2021-23 biennium, 40% is allocated to dairy digester bioenergy projects that produce renewable natural gas and biofertilizers, reduce emissions, and improve soil, air and water quality. Please find additional information on the broader Rural Clean Energy Innovation Grants Program on the webpage.
Save the Date: Dairy Digester grant applications will be solicited in early spring 2022.
Clean Energy Fund 4 Dairy Digester Enhancement Program
- In May 2020 Commerce announced $970,000 in grants from Clean Energy Fund 4 (2019-21 biennial Capital Budget) through a competitive application process.
- Awards included at least one project east of the Cascades and one project west of the Cascades.
- Four projects were funded to improve energy efficiency in operations and the marketing of biogas, nutrients, fiber and other co-products of the digesters.
- All of the grants had to 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
