I think that's an exaggeration, and neglects the possibility of overbuilding solar/wind. It may mean leaving your relatively low capital expenditure wind and solar farms 50% underutilized for half the day but the benefit here is that you can guarantee a 95% capacity factor year-round for the expensive electrolysis plant.
- ncmncm 4y agoElectrolysis equipment will move relentlessly toward 100% usage, drawing down other forms of storage, and transmission lines, when top-line generation flags. You might turn it off just when demand peaks. We absolutely will overbuild solar and wind to have enough to charge up storage for 24-hour use. Making hydrogen will be such a use.
