Passamaquoddy Tribe at Pleasant Point algae to Oil Project Steve Crawford, M.Sc Environmental Director
Overview and Background • Tribal energy mission statement: To be 100% self-sufficient in energy, while safeguarding the Tribe’s lands, waters, air, human health, and culture. • Projects under development: • Commercial wind – 50.5 MW wind project on Blueberry farm • In-stream tidal power, two-FERC approved sites in Passamaquoddy Bay • Half-moon Cove tidal barrage 10 MW project • Geothermal project with Passamaquoddy Bay for heat • Domestic wind turbines, solar panels
WINDPOWER SITES Wind power site Wind power site Windpower site
Sipayik 100 gal. bio-reactor, sewage treatment plant (250 ml/4 day)
ECONOMICS • Preliminary Results: • 1000 gal bio-reactor will produce approx. 1 gal/wk • Demo-600 sq.ft greenhouse will produce 100 gal/yr • 8 ft bio-reactor tubes, instead of 4 ft, will produce 400gal/yr/1000 sq. ft • Infra-structure cost $40,000 • Over 20 yrs, produce 8,000 gal, = $5/gal. • THIS IS STUPID!??
ECONOMICS (2) • This is stupid rebuttal. • Enter the Federal Government. • US exploration for oil in 2009 costs $79 billion; global costs were $439 billion • Shell oil paid $2.1 billion just for the rights for Arctic leases. • US government paid oil and gas industry $36.5 billion in subsidies, equals 1% of oil and gas company revenues.
Economics (3) • This is stupid, continued. • The capital cost of the algae-oil project to the Passamaquoddy Tribe, to produce 100 gal of oil/yr for the next 20 years, is $0.00. operating costs = $100/yr= $1/gal • US EPA provides $68 million/yr to federal tribes in IGAP program for environmental departments. $100-120k per tribe/yr. • If DOE/USDA Rural Development/DOI provided a one-time grant of similar size to every tribe, every tribe could produce 100 gal/yr. • Those that want it, scale up to 1,000 gal/yr.
ECONOMICS (4) • This is stupid, continued. • Thinking bigger: • 1000 sq. ft = 400 gal in 8 ft tubes; 1 acre = 17,000 gal, 1 sq. mi = 10,000,000 gal/yr. • (100 ft plus high tubes are being used) • Cost guestimate of $1,720,000/acre= $1,2 billion per sq. mile. • LAST YEAR’S SUBSIDIES WOULD PAY FOR CONSTRUCTION OF 30 SQ. MILES OF ALGAE-OIL BIO-REACTORS, PRODUCING 300 MILLION GAL OF OIL/YR
ECONOMICS (5) • This is stupid, continued. • Maybe it isn’t so stupid. • Carbon-neutral. • Exxon-Mobil, arguably the most conservative oil company, is investing $500 million in algae-gasoline project. • 100 sq. mi production = 1 Billion gal = 3 day’s use, 1,000 sq. mi = 2 weeks. • Just opened that much area in Alaska last week for new drilling.
Costs • 18’ x 28’ x 10’ greenhouse: $4,450 • 40 – 4 ft x 1 ft acrylic tubes = $4,000 • Air pump=$ 1,500 • CO2 supply $500 • Plumbing= $3,000 • Floor and sill= $600 • Extraction process= $4,000 • Installation= 40 m-hr @$20/hr= $800 TOTAL = $17110, rounded up to $20k
Summary • KEY POINT-SELF SUFFICIENT! • Carbon Neutral • Waste products, when using Chlorella (42% oil dry-weight) • Waste gas = oxygen • “oil cake” is dried chlorella, sold in health food stores for $700/lb • Fertilizer can be sewage effluent
