One big problem with all these renewable energies is they are prone to producing electricity at the wrong time and they cannot be easily switched on and off when required. That means the electricity they produce cannot be sold for much. The ability to store that electricity would make it far more valuable.
True. Unfortunately, there are no viable storage methods on the scale we need.
Very very wrong. Nuclear provide a baseload supply. It is not an intermittent supply governed by the whim of nature. A normal reactor will generally have a capacity factor of about 90%. The remaining 10% is generally scheduled shutdowns for refuelling, meaning that the grid can easily cope with it, as it is planned.Funnily enough the same problem applies to nuclear.
GenIV reactors are thought to be able to provide a variable supply, and this is due to the lower cost rather than a technical fix.
Using wind turbines to produce petrol in this way would be prohibitively expensive.So if they could turn that low value electricity into high value petrol then it might make economic sense even if the conversion was uneconomical - in theory at least Somebody needs to put together a spreadsheet !
