Total global electric power capacity is about 5,250,000,000 kW, or 5,250 GW. About 1,039 GW is in the US alone. FlexForm solar plants are estimated to cost about $1020/kW ($220/kW for collectors, $500/kW steam plant, $300/kW for thermal storage – for 66% duty factor).
Without Hydrogen – generation from direct solar and thermal storage –
Total available market estimated at 20% of global market, or 1050 GW
Market penetration rate estimated at 5% of that per year, for an annual market of 55 GW/yr, at $220 per Kw for the collector, or $11.5 B/yr for the collector portion.
With Hydrogen – solar thermal electric to hydrogen to fuel cell electric –
Total available market estimated at 60% of global market, or 3150 GW
Market penetration rate estimated at 5% of that per year, for an annual market of 165 GW/yr, at $440 per Kw for the collector (at 50% solar electric to H2 electric efficiency) or $69 B/yr
