Unified Field Study 1 (UFS-1)

Published by National Renewable Energy Laboratory | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-03-12T18:48:49Z
The Unified Field Studies (UFS), established by the Algae Testbed Public-Private Partnership (ATP3), produced data on the effect of environmental and process conditions on algal growth rates and algal composition. The goal of the UFS-1 experiment, performed October to December 2013, was to establish the operational capability to simultaneously perform the same algal growth experiment using identical equipment, media, strain, experimental protocol, and analytical techniques across the 6 ATP3 testbed sites. A common algal species (Nannochloropsis oceanica KA32) was grown at all sites. The UFS-1 Experiment was intended as a first live run-through using the full volume and capabilities of the 6 identical ATP3 ponds to build pond operator familiarity with the equipment and procedures in an effort to eliminate operator error from the upcoming UFS Production runs. For more information about the UFS experiments see the reference resources 0.0 UFS-1 Experiment OpenEI Wiki Page, 0.1 ATP3 OpenEI Wiki Page, 0.2 Report on the Use of ATP3 UFS Data, and 0.3 ATP3 UFS Journal Article below.
