Hello, World! Hello, Bluesky!
PyPSA is now officially on Bluesky - it took a couple of years and a major version release, but we're finally here!

Designing a sector-coupled European energy system robust to 60 years of historical weather data - Nature Communications Highly renewable energy systems, built on wind, solar PV, and sectoral integration, can handle year-to-year weather variability while ensuring resource adequacy and CO2 neutrality, at 10% higher cost ...

Hintergrund war die Pressekonferenz des Deutschen Wetterdienstes zum Energiewetter 2025, sowie eine unserer Studien zu diesem Thema:

Klimawandel: Windkrafträder in Zukunft weiter im Aufwind Klimawandel: Windkrafträder in Zukunft weiter im Aufwind

Wie ein klimaneutrales Energiesystem mit viel Wind und Solarstrom auch in den kritischsten Dunkelflauten mehrerer Jahrzehnte funktionieren kann, wird vielfach wissenschaftlich erforscht. Gestern konnte ich dazu ein paar Sätze in den ARD Tagesthemen sagen.

www.tagesschau.de/tagesthemen/...

- Updated electricity demand time series from ENTSO-E/NESO and spatial distribution from JRC Energy Atlas.

- New interactive visualisations of results using Pydeck.gl.

- Improved technology parameters, data versioning, configuration validation, and dependency management + Bugfixes.

- Updated OpenStreetMap grid data, now supported down to 63 kV.

- Updated power plants and industrial sites data, including recent Global Energy Monitor / TransitionZero wind and solar updates and existing battery capacities.

- Updated energy balances from JRC-IDEES 2023, Eurostat, & Switzerland.

PyPSA-Eur Workshop at DTU Part 1/3 Electricity sector YouTube video by Marta Victoria

@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.

Green energy and steel imports reduce Europe’s net-zero infrastructure needs - Nature Communications This study examines cost reductions, volumes, & vectors of green energy imports to Europe, showing diminishing returns at higher volumes and a preference for methanol, steel and hydrogen imports.

Curious about the full scenario landscape? Dive into the open-access paper! 📖🌐

www.nature.com/articles/s41...

Import choices shape infrastructure needs:

Smaller size of the hydrogen network when green fuels and materials are imported at scale and ammonia- or steel-making can relocate within Europe.

Keeping some European power-to-X in Europe has some advantages:

Flexible operation helps balancing wind and solar variability.

Its waste heat could be supplied to district heating systems in urban areas.

Using Europe’s biogenic and industrial CO₂ streams means lower dependency on DAC.

Only focusing on direct hydrogen imports cuts cost benefit in half.

Imports of derivative products like ammonia and methanol are preferred

Importing green energy and steel products (like HBI) has some advantages:

System costs fall by 1–10 % across a ±20% import cost range

In this range, cost-effective import volumes range between 1000 and 2000 TWh (~30-60 Mt H₂-eq)

No cost savings beyond imports of 3000 TWh (~90 Mt H₂-eq)

What we explored:

A full sweep of scenarios, interpolating between complete self-sufficiency and wide-ranging imports, plus sensitivity tests on low vs. high import prices and on excluding specific vectors to map the cost-effective space.

What we learned:

It really was a fascinating conversation. He's very good on Russia and decarbonisation, and stood his ground when I pushed him pretty hard on energy costs and hydrogen.

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:

H2 and CO2 network strategies for the European energy system - Nature Energy This study on European carbon management shows how H2 and CO2 networks influence whether CO2 is transported to renewable hubs and sequestration sites or H2 is delivered to industrial sites for producing clean fuels from captured CO2.

New work from Hofmann and colleagues shows how hydrogen and carbon dioxide networks influence whether CO2 is transported to renewable hubs and sequestration sites, or H2 is delivered to industrial sites for producing clean fuels from captured CO2.
