Impact Bioenergy's Vashon Bioenergy Farm

The Vashon Bioenergy Farm (VBF) is a community-scale bioenergy system on Vashon Island, Washington. For every 60 to 80 pounds of “waste” that would otherwise have been long-haul exported, Impact Bioenergy’s NAUTILUS generates one gasoline gallon equivalent (GGE). This first NAUTILUS "biocycles" up to 8,000 lbs. of commercial food waste per day from the Island Spring tofu factory and local restaurants. This is enough to fuel a small fleet or provide heat & power for more than 40 homes.

The NAUTILUS AD 185 series modular anaerobic digester is a systemic and holistic community solution for colocation at or near a source of organic waste and nearby energy loads. The close proximity conserves energy that would have been expended for transport and processing of materials, and centralized power generation. A lifecycle assessment of the NAUTILUS underscores its net-negative carbon intensity, when utilized as renewable fuel for vehicles, and net-positive energy and organic value propositions.

The NAUTILUS offers a virtual-pipeline that adds resiliency and augments intermittent renewable energy like solar or wind. Biogas is continually generated and stored for use when needed. It can generate heating, cooling, electricity, and vehicle fuel. The VBF NAUTILUS employs a unique integrated biogas upgrading system to generate renewable natural gas (RNG) that is stored with state-of-the-art Adsorbent Natural Gas (ANG) technology where it is compressed to up to 250 psi. With ANG storage, Impact Bioenergy demonstrates economically viable pathways to the lowest carbon intensity fuel that avoids high costs, low storage efficiency, and safety concerns associated with conventional approaches. The VBF fueling station provides up to 125 GGE of CNG vehicle fuel per day.

VBF also reclaims over 2,000 pounds of nutrients and 300,000 gallons of water annually for rich, probiotic plant food to promote the healthy growth of the community’s own food, flowers, and landscape. Sold under the brand name PBF (ProBiotic Food, for plants), it enables the replacement of synthetic and imported fertilizers with locally produced organic fertilizer. Allowed under the USDA National Organic Program, PBF cultivates more biomass, vigor and nutrient cycling.
