Dessa två scenarier förutspår mer än en fördubbling av…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos What if Europe had a perfectly connected power system in 2050? With no transmission network limitations. This will be a long post, juggling large numbers, and with many assumptions that will make this investigation rather speculative. Anyway, you have been warned! What I have done is to use Energy Charts combined data…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos BackgroundThe modelSimulationsDiscussionConclusions Background Following the same trend as many other countries, Portugal plans to increase its power generation to support more electrification, especially for hydrogen production to support a Power-to-X industry. In the so-called “conservative scenario” almost all the increase in power consumption targets the latter industry, while “classical” consumption is projected…

Here is a simple model and simulation of how such a power system could behave under three years, based on wind and solar…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos IntroductionModelResultsConclusionsUpdate 2023-12-02 Introduction Offshore wind power and nuclear power are both complex and costly animals. Both are proposed to provide power in bulk to many regions. Just based on LCOE for each power type, offshore wind power has the upper hand based on a slightly lower LCOE in general. But what happens…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos IntroductionModelScenariosResultsDiscussionConclusions Introduction Sweden’s future power system must accommodate up to 300 TWh of electricity consumption per year in the future according to many analysts. This is also often mentioned in the press. This is more than double the consumption of today which is about 140 TWh. Typical production today is around 170…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos In the last blog post, I compared the Solar/Wind/Eco/Nuclear/Storage (“SWENS”) model with a similar model described by Ruhnau/Qvist (“RQ”), using as similar cost parameters and other presumptions as possible. While the RQ model is much larger in scope than my simpler SWENS model (remember, this is a blog, not a scientific paper……
