With the current government coalition negotiations in Germany a bidding zone review, i.e. bidding zone split, just became slightly more probable.

SPD in favor, CDU still against it.

Wonder where the future European hydrogen demand will be located and what is driving it?

@ffe-sciencebased.bsky.social had a look it in the #TransHyDe project. The map shows at NUTS-3 level:

-regional hotspots
-infrastructure demands

Demand flex?

Real world 🇫🇮numbers by @Rautainen from last Friday.

Day ahead prices reached ~2000 €/MWh and spot-customers showed significant demand reduction (Chart 1).

One would think great! But actually this caused some problems. Short thread in English.

The grass is always greener on the other side?!

Not quite: The US go a very similar approach as in the EU regarding electricity supply requirements for electrolyzers.

What I still wonder how strict the emission balancing will be in practice.

Bei den Emissionsminderungen zum Klimaschutz liegt Deutschland auf Rang 16 der 38 OECD-Staaten. Also leider nur im Mittelfeld - als führende Industrienation und einer der weltweit größten CO2-Emittenten (#7) sollten wir vorne mit dabei sein!

Primary, secondary, final, and....

Colleagues from @ffe-sciencebased.bsky.social @bdew and @AGEBeV published interactive charts that show what happens "after final energy". Check it out!

Neue Studie von Agora / FfE zu dezentraler Flex

Mit Festpreis *erhöhen* die neuen Stromverbraucher EV, Wärmepumpe + Heimspeicher die Last in den kritischen Abend- und Morgenstunden um durchschn. 10 GW (Simulation 2035)

Mit dynamischen Tarifen *senken* sie sie um knapp 10GW Jeden Tag.

Black Friday day ahead: 🇫🇮 will see 10 hours of -500€/MWh due to a bidding error of a market participant offering erroneously more than 5 GW.

Let‘s see whether Finnish saunas will glow. More seriously: Definetely an interesting day tmrw.

Future electricity systems in the EU rely mainly on wind and solar. Many of you ask: what happens when there is no wind or sun?

Electricity storage and interconnection to the rescue! But how do these two interact?

🧵 Get ready for some energy modelling content!

Siemens Energy has major financial problems and wants massive guarantees from the German government, of up to €10 billion. This is problematic for at least three reasons, in 🧵:

Next step: Peak fossil primary energy consumption!
Power (=electricity) is good, but not enough!

Beginning of a new era:

Twitter/X is replaced by Bluesky.

And my 45 year old analogue Ferraris meter is replaced by a digital meter.

Looking forward to both changes!

P.s. Obviously the new digital meter will not be online. This is Germany 2023.

In the field of #energy, we face the same old lies and #myths every day. Especially when it comes to new technologies and transformation. This holds true for the pros and cons! We should stick to the sometimes inconvenient truth! #factbaseddecisionmaking is the only solution!
