- pfdietz 3y agoCombined cycle powerplants are > 60% efficient (LHV). The LHV of hydrogen is 33.3 kWh (of heat) per kilogram. Yes, it would be inefficient overall. And it's still cheaper than nuclear. Throw in a large fraction of energy not going through hydrogen (direct to grid, or through batteries) and the cost would be even lower.
