Historical Costs
see Fig.1
Cost of new designs
ThorCon MSR:
$1200 per kW + $0.03 per kWh [2]
Cost of alternatives
Rooftop Solar (no batteries):
$2,900 per kW (nameplate), $11,600 per kW avg (25% Capacity Factor)
Wind Turbines
$770–$850 per kW (nameplate), down from $1800 in 2008.[3]
$3240 per kW avg (25% Capacity Factor)
Batteries:
Lead-Acid: $300 per kWh
Li-ion:
Hydrogen:
Worldwide hydrogen production stood at 90 Mt in 2020, but since it was produced almost exclusively from fossil fuels, the result was close to 900 Mt of CO2 emissions.[4]
"Green" hydrogen (no CO2) can be produced from water using electrolysis, but the cost is much higher.[5]
$2 per kg promised by mid 2020s[6]
$1 per kg ten-year goal set by DOE[7]
$0.12 per kWh electrical energy storage cost, assuming $2 per kg of H2, and 50% overall efficiency.[8]
