Since everyone is busy "resetting", here is a more focused plea: let's manage our sustainable biomass better. People get nervous around biomass (it's complicated!) but high costs for green hydrogen and direct air capture mean we need to take a closer look. Blog: nworbmot.org/blog/biomass...

“By 2040, the Locational scenario could reduce the total system cost by 23 – 59 Bn. EUR annually. These savings are in the order of magnitude of those associated with the integration of European electricity markets.”

PyPSA v1.0 is officially here - 10 years and 2 days since the first git commit. This milestone release brings major new features, completely new documentation, and a fresh landing page - congratulations to all the PyPSA team! 🎉 🔗 New Documentation: docs.pypsa.org 🔗 New Landing Page: pypsa.org

Explosive stuff on Elsevier's journal publishing business from the previous (now fired) editor-in-chief of Energy Economics...the rot seems deep.

🔋 Die #Energiewende erfordert Investitionen von 116–131 Mrd. €/Jahr. Gleichzeitig sinken fossile Importe & Haushalte sparen Geld. Zu diesem Ergebnis kommt @nworbmot.bsky.social von der #TUBerlin im Ariadne-Report 2025. Sein Appell: Erneuerbare & Elektrifizierung müssen vorangehen. Zum Interview ⬇️

@nworbmot.bsky.social is doing really important stuff again, simulating how methanol (instead of hydrogen) could be the fuel to power a system otherwise mainly running on solar, wind and batteries. SUPER interesting paper. arxiv.org/html/2505.09...

It's great to see METI's 7th Strategic Energy Plan for Japan, but 60-70% nuclear+renewables in 2040 in electricity seems low. 30-40% non-nuclear thermal generation (fossil gas + CCS, e-hydrogen, e-ammonia) is going to be expensive. www.enecho.meti.go.jp/en/category/... #iew25 #energysky

My old posts are now on a blog. Since many of our social media platforms are walled gardens and some are now owned by fascism-sympathisers, I've back-ported all my posts and threads onto a blog: nworbmot.org/blog/ It was fun re-reading some of the older Twitter threads, here are some fun ones:

"Wie wird Deutschland klimaneutral?" Diese wichtige Frage stellt mein Kollege @wpschill.bsky.social in der neuen Folge seines Podcasts. Mit dabei: @gunnarenergyclima.bsky.social (@pik-potsdam.bsky.social) und @nworbmot.bsky.social (@tuberlin.bsky.social) aus dem @ariadneprojekt.bsky.social.

As the hydrogen bubble deflates, what are the alternatives? We present a "minimal methanol economy": using methanol as a gap-filler for the few sectors electrification can't reach. New working paper together with Philipp Glaum, @fneum.bsky.social, @millinger.bsky.social: arxiv.org/abs/2505.09277

What might a future CO₂ pipeline network look like in Europe? And how might it interact with hydrogen infrastructure in scenarios with e-bio-fuels for aviation, shipping and chemicals? Read our new @natureenergy.bsky.social paper to find out!

✈️🚢🧪For Europe's green fuels for aviation, shipping, and chemicals: Should we pipeline H₂ to industrial CO₂ capture sites, or CO₂ to regions with better renewable resources for H₂ production? 📖 See our new study in @natureenergy.bsky.social on future carbon management: www.nature.com/articles/s41...

New paper! Data center growth, electrification, and H2 plans have made electricity demand highly uncertain. So how should we future-proof our power systems? We show that deploying more renewables and storage can hedge against demand risk. Open access: www.sciencedirect.com/science/arti... 🔌💡

It wasn’t net zero — it was fossil gas that drove up UK electricity prices. Spot on, @pilitaclark.bsky.social! Gas sets the price most of the time. As @dharavyas.bsky.social Energy UK, says: "It’s the volatile cost of fossil fuels and our dependence on them that have driven up energy bills."

Helpful focus on sovereignty here. It is the key issue. www.justsecurity.org/109084/putin...

By better design and operation 𝐚 𝐭𝐡𝐢𝐫𝐝 of the planned network development cost (~€90 bn of the proposed €283 bn) in Germany could be saved ...according to @nworbmot.bsky.social & team, based on PyPSA modelling in the new @ariadneprojekt.bsky.social report. ariadneprojekt.de/pressemittei...

Vorschlag: Anstatt die Übertragungsnetze dauerhaft zu subventionieren, lieber kosteneffizienter bauen und ein Teil der Kosten mit einem Amortisationskonto um ein paar Jahre verschieben Nach unserer Berechnung kann man mit kluger Planung etwa 92 Mrd. EUR (einen ,,Wumms'') sparen

Die neuen Szenariorechnungen zur Klimaneutralität 2045 aus dem @ariadneprojekt.bsky.social sind da! 🔽 Wie schon in früheren Studien zeigt sich, dass erneuerbarer Strom der wichtigste Energieträger wird. Ein schneller Ausbau von Windkraft & PV und ihre Nutzung für Mobilität und Wärme sind essenziell.

#Ariadne-Report kalkuliert Pfade zur #Klimaneutralität 2045 in Deutschland: Der Zusatzaufwand der #Transformation lässt sich durch kosteneffizienten #Klimaschutz je nach Szenario auf jahresdurchschnittlich 16 - 26 Mrd. Euro bis 2045 begrenzen, 0,4 - 0,7 Prozent der heutigen #Wirtschaftsleistung.
