More Confirmation Of The Infeasibility Of A Fully Wind/Solar/Storage Electricity System

Many recent posts on this blog have dealt with the theme of the infeasibility of a fully wind/solar/storage electricity system. Today I will deal with another study of the subject, this one from German authors Oliver Ruhnau and Staffan Qvist, titled “Storage requirements in a 100% renewable electricity system: Extreme events and inter-annual variability.” The Ruhnau/Qvist study does not have a date other than “2021,” although it appears to have come out toward the end of that year.
Although Ruhnau and Qvist do not say it explicitly, my conclusion from their paper is that it is a further demonstration of the complete infeasibility — indeed the complete absurdity — of attempting in the short term to replace all fossil fuel electricity generation in a modern economy with only wind, solar and storage.
The background of this issue is that large numbers of green activists, up to and including the current President of the United States, make regular statements indicating that they believe that fossil fuels can be eliminated from the modern economy by simply building sufficient capacity of wind and solar electricity generation. Such statements rarely consider or mention the necessity of energy storage, or the feasibility or cost of same. And yet any serious consideration of the intermittency of wind and solar inevitably leads to the conclusion that without dispatchable backup (fossil fuel or nuclear) they require vast amounts of energy storage to cover the periods of intermittency. Understanding the amount of storage required, its physical characteristics, and its cost, is completely essential to answering the question of whether a fully wind/solar/storage system is feasible.
