  • Optimized SWENS model for Germany

    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……

  • Benchmarking SWENS model for Germany with Ruhnau/Qvist model

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos Oliver Ruhnau and Staffan Qvist (“RQ”) presents a very illuminating analysis of Germany’s storage need for a fossil free 540 TWh consumption scenario here (and here in a short Twitter thread). Basically, their power system is fueled with 700 TWh of renewable energy for a consumption of 540 TWh. The difference is…

  • SWETH and SWENTH model for Germany

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos SWETH systemSWENTH systemDiscussionConclusionsUpdate 2023-07-08 Modeling a fossil free German power system Inspired by the RethinkX SWB (Solar, Wind and Batteries) model (see this blog post), a more realistic model for Germany, with 500 TWh of consumption, is presented here. The model is based on either of these two alternatives SWETH Solar, Wind,…

  • Rethinking RethinkX for Germany 2030

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos RethinkX has presented a proposal for replacing Germany’s power system with an all renewable power system consisting of wind and solar power only, and with batteries as back-up/balancing source (a “SWB” system). It would also be a completely self-sufficient power system, with no import dependence. From a modelling point of view this…

  • Hydrogen storage dynamics at the national level

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos This blog is a translation of an article I wrote for the Swedish on-line magazine Second Opinion. In this article, Bengt J. Olsson evaluates different methods for generating the green electricity needed for hydrogen production. His conclusion is that electricity from a balanced national electricity system provides the best and most even…

  • “Power to Products” scenario for Finland 2035

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos Update 2023-04-16: Added a section about the nuclear fueled “Local power” scenario in the end after the Summary. The Finnish TSO Fingrid Oy recently published a report describing four possible future scenarios for the Finnish power system 2035 and 2045. The scenarios are In this blog post, we will examine the “Power…

  • Power balance in Norway 2050

    Bengt J. OlssonTwitter: @bengtxyz  Norway is blessed with fantastic natural resources. Not only in the fossil space but also in order to produce abundant amounts of clean power. The basis for this is their huge hydro power capacity. We will here use a simple balance model to depict what the Norweigan power system could look like…

  • A balance model for Denmark 2030

    Bengt J. OlssonTwitter: @bengtxyz  The balance model described in this post is used to model the behavior of a future power system for Denmark in 2030. The model is based on production/consumption numbers proposed by “Denmark’s Climate and Energy Outlook 2020” (DCEO) for 2030. The idea with the simulation is to simplify the model as far…

  • Balancing with hydrogen instead of hydro?

    Bengt J. OlssonTwitter: @bengtxyz  An interesting “gedanken” experiment would be to have a scenario where hydro power in Sweden is exchanged with green hydrogen power for balancing the power supply and demand. After all, not many countries are blessed with the natural resources in form off hydro power that we have in Sweden and Norway. In…

  • Power balance in Sweden 2020-2021

    Bengt J. OlssonTwitter: @bengtxyz  The balance model described in this earlier blog post is very versatile for testing and evaluating different power mix scenarios. In this post we will return to the year of the included wind data which is kind of key to the model. We will look at some aspects of the model applied…
