Usually that works, but not always. It's the last part that's the killer. When you optimize against historical weather data in Europe to produce steady power at minimum cost, a wind/solar/battery/hydrogen system cuts the cost in half compared to wind/solar/battery. As I said elsewhere I'm thinking ultra low capex thermal storage will edge out hydrogen here, though.
