Wind and Solar diurnal and seasonal variations require energy storage

Preface. Solar power can’t possibly provide power year-round, it varies far too much (Smil, V. 2017. Power Density. MIT): “Differences in monthly insolation averages depend on latitude and cloudiness: in Oslo the difference between January and June is 16-fold; in … Continue reading

CSP with thermal energy storage is seasonal, so it can not balance variable power or contribute much power for half the year

Concentrated Solar Power not only needs lots of sunshine, but no humidity, clouds, dust, smog or or anything else that can scatter the sun’s rays.  Above 35 degrees latitude north or south, the sun’s rays have to pass through too … Continue reading
