This data reflects the latest analysis from the 2022 Algae Harmonization Update, which uses the latest parameterized and high-performing saline algal strain, second-generation carbon capture of point-source waste CO2 and high-pressure pipeline transport resolved to specific point-source types, saline water sourcing up to 40,000 mg/L total dissolved solids for source and makeup water salinity, blowdown water treatment and recycle, and brine disposal handling.
Description:
Land-screening sites based on culmination of data through 2020 at a minimum contiguous area of 1,000 acres
Modeled biomass growth based on lab parameterizations of Tetraselmis striata LANL 1001 saline strain (DISCOVR program) using 40-years of hourly meteorology from NLDAS-2.
Microalgae growth model coupled with a pond temperature model at 10 acres per pond running at an operating salinity of 55,000 mg/L.
Cultivation productivity targets 26 g/m2-day annual average based on nutrient-replete, high-protein biomass composition at harvest.
Microalgae harvest set at a density of 0.5 g/L to maximize productivity.
Harvested microalgae sent through three-stage dewatering via gravity settling, membrane concentration, and centrifugation to 200 g/L.
Saline groundwater used as the exclusive source of water that is accessed at depths no greater than 500 m
Blowdown water disposal via forward osmosis brine concentration and well injection; clarified water from forward osmosis is recycled internally within the algae farm.
CO2 capture and transport uses 2020 viable point-sources and reported annual mass, with capture costs and energy demands varying by CO2 concentration in the point source; CO2 utilization efficiency of the microalgae is set at 75%
Urea and diammonium phosphate are used as nitrogen/phosphorus nutrients and are based on biomass productivity and composition
