1/ Wochenlang haben alle auf den Monitoringbericht zum Stand der Energiewende und die Schlussfolgerungen des Wirtschaftsministeriums gewartet. Nun sind die Dokumente da - aber sind wir jetzt so viel schlauer als vorher? 🧵

when the FT revealed in January that the cost of building the Sizewell C nuclear plant had risen to around £40bn they all denied it now we can reveal the actual price tag - to be announced this week - and it is £38bn www.ft.com/content/d431...

@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...

"What do you think about hydrogen-ready boilers?" I was asked by tagesschau.bsky.social My response: "If I have a garage, I can also say it's ‘Ferrari-ready’. I could park a very expensive sports car in there. Hardly anyone does that because it's too expensive." www.tagesschau.de/wissen/klima...

Cool new study looking at near-optimal solutions for biomass in a future European energy system. Biomass is particularly valuable for providing carbon, less so for energy. Also some interesting points on IAMs in comparison to detailed energy system models like PyPSA.

A 100% must-read for everyone that has ANY stakes in hydrogen. Frankly, the H2 ramp-up is not going great right now globally, and Adrian and Falko have the numbers. I think we are reaching a phase of honesty, where we have to turn the popping bubble of over-expectations into something productive.

Unfortunately, Germany doesn't have great renewable resources. So making industrial raw materials from hydrogen here would be very expensive. Instead, import green raw materials and focus on high-value added production steps! Thanks for covering our report @cleanenergywire.bsky.social

Thanks for sharing our article @janrosenow.bsky.social! Sadly, two years after its publication, most green hydrogen projects have been delayed or abandoned. @falkoueckerdt.bsky.social and I will soon publish a follow-up article to explore recent setbacks and future challenges of green hydrogen.

#Lindner will "mehr Milei und Musk wagen" !!!👇 Wow, das hätte ich echt nicht für möglich gehalten! Eine wirklich extrem gefährliche Radikalisierung. Autoritärer Liberalismus trifft es leider wirklich ziemlich gut.

Das ist echt der Gipfel der Unanständigkeit! Die Lüge fliegt auf und dieser Generalsekretär tritt nach unten und wälzt die Schuld auf „Mitarbeiter“ ab.

Energy Exemplar has blocked all TU Berlin students from academic licences for their energy modelling tool PLEXOS because competitor PyPSA is developed here. While deeply shocked, we believe in turning the other cheek. So we are offering all Energy Exemplar employees a free licence for PyPSA.

Is limiting the temperature increase to 1.5°C still possible? It should be a rather easy question to answer, but we all squirm and find it difficult due to the social pressures. Maybe crossing 1.5°C is the wake up call we need? journals.sagepub.com/doi/10.1177/... 1/

Hello, I'm here.

1. Das hier aus dem Lindner-Papier ist irreführend und sehr weitreichend: Dass es zusätzlich zu den EU-Klimazielen Ziele in den Ländern gibt, trägt der Tatsache Rechnung, dass die Mitgliedstaaten unterschiedlich weit und unterschiedlich reich sind. (Kurz-Thread 🧵)
