  • Scenarios for a Pan-European power network in 2050

    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…

  • Portugal 2040, power system according to the RMSA “conservative scenario”

    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…

  • Denmark 2040 – RE and nuclear alternatives

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos BackgroundThe modelSimulationsDiscussion and ConclusionsUpdate: Nuclear-only alternativeHydrogen storage in Denmark Background Denmark has plans to massively build out wind and solar power and also to produce hydrogen for PtX purposes. Here is a simple model and simulation of how such a power system could behave under three years, based on wind and solar…

  • A simple model for comparing the costs of offshore wind power and nuclear power

    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…

  • Hydrogen sector-coupled model for Sweden 300 TWh

    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…
