Our company, Alaska Applied Sciences, Inc., (AASI) owns a 13-turbine windplant in Palm Springs, CA. It has been stranded since June, 2012, with no connection to the SCE grid, because the power purchase agreement (PPA) has expired. We plan to convert this small windplant to produce high-purity hydrogen fuel, for buses and cars, by feeding its total annual energy production as DC electricity to electrolyzers, to split water molecules into hydrogen and oxygen gases. The carbon-emissions-free hydrogen gas would be compressed to ~ 3,500 psi (~ 230 bar) into tube trailers for delivery to local Southern California markets.
The 1985-vintage wind turbines are equipped with three-phase squirrel cage induction motors, as generators. These motors will be operated in "Self-Excited Induction Generator" (SEIG) variable speed mode, with their "wild AC" output converted to "wild DC" for the electrolysis plant.
This $ 4 million project needs $ 2.85 million in new funding, for which we have applied via the USDOE "ARPA-E" program, on 25 Feb 15.
