HeliWind Power Station

Intermittent power is a problem with wind power.   Here’s a solution.  A Hybrid!  When the wind blows (40% at a good wind site), an electrolysis unit generates H2-O2 for storage in the main HeliWind balloon and adjacent gas storage balloons.  An internal combustion (or turbine) engine drives the genset during periods of low wind.  For peak electrical demand, both the engine and the balloon drive the genset.  A 10% energy loss during electrolysis and a 40% loss by the engine are assumed.  (Most IC engines lose 70%).   216 kW-hrs of power is converted into H2-O2 and stored, but 50% of this energy is lost during the engine cycle.  Exhaust from the engine is 100% steam and is used to heat the fill gases inside the HeliWind, allowing for some energy recovery. Genset heat also is fed back into the balloon.  Power produced by the system is estimated at 212 kW-hrs per day.  The downside is cost.  40% of the wind energy is lost and generation rates soar to $ 0.127/kW-hr.
