Without costly connection to, nor energy delivery to, the electricity grid, wind turbines and windplants of all sizes may be simplified
in design and reduced in cost by equipping them with novel-technology Self Excited Induction Generator (SEIG) systems producing
high-purity Hydrogen fuel at lower cost/kg. The simple, rugged, low-cost induction motor on each turbine produces “wild AC“ rectified
to a “wild DC“ bus interconnecting two or more turbines, minimizing power electronics. Electrolysis stacks are close-coupled to the
“wild DC“ bus, eliminating the costly “transformer-rectifier“ subsystem. Complete wind-to-Hydrogen system controls are integrated
in single SCADA system. These distributed, autonomous windplants deliver only Gaseous Hydrogen (GH2) fuel to large new, dedicated,
high-purity, underground, GH2 pipeline systems for gathering, transmission, storage, and integration of diverse, stranded, renewable
energy resources.
California‘s achievement of both Renewable Portfolio Standard (RPS) for electricity and “80-in-50“ reduction in transportation sector
CO2 emission (80% below 1990 by year 2050) cannot be achieved via electricity systems alone, but will require ~7 million tons/year
of high-purity Hydrogen fuel, from CO2-emission-free sources, by year 2050, for light duty vehicles, buses, and trucks, requiring full
output of about 200,000 MW of nameplate wind generation plus 200,000 MW nameplate solar-PV generation.
Fig. A: Distributed, autonomous production of wind-source hydrogen fuel enabled by simplified turbine generating systems, with elec-
trolysis stacks close-coupled to the windplant DC bus, for lower capex and O&M costs. Self-Excited Induction Generator (SEIG) enables
simple, robust, low-cost induction motors as generators.
