A world without gas infrastructure? If we aggressively electrify the economy, green methanol could cover most of the remaining non-electric demand - without needing large-scale hydrogen or methane networks. New paper in Joule: "A Minimal Methanol Backstop for High Electrification Scenarios"

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/...

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.

Fabian Neumann @fneum.bsky.social · 12/06/2025
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.

Fabian Neumann @fneum.bsky.social · 12/06/2025
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.

Fabian Neumann @fneum.bsky.social · 12/06/2025
Only focusing on direct hydrogen imports cuts cost benefit in half. Imports of derivative products like ammonia and methanol are preferred

Fabian Neumann @fneum.bsky.social · 12/06/2025
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:

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.

In the paper, we also explore some more scenarios, e.g. with none or only one of the networks available. So if you're curios about a detailed infrastructure view on Europe's Carbon Management Strategy, have a look! We look forward to your questions! 🌱 Of course, this was made with #PyPSA 😉

Fabian Neumann @fneum.bsky.social · 11/04/2025
We also find that the combination of both networks remains advantageous when climate targets are tightened toward net CO₂ removal. The CO₂ network allows effective utilization of unavoidable industrial emissions through capture and transport to utilization or sequestration sites
140
Fabian Neumann @fneum.bsky.social · 11/04/2025
We show that dividing tasks between networks can be cost-effective: hydrogen pipelines deliver hydrogen from the South to industrial centres for fuel synthesis, while CO₂ pipelines transport captured emissions from these clusters to geological sequestration sites, e.g., in the North Sea.
130
Fabian Neumann @fneum.bsky.social · 11/04/2025
Also: Captured CO₂ from some residual industrial emissions, or biomass for negative emissions, will need to be transported to geological storage sites.

Fabian Neumann @fneum.bsky.social · 11/04/2025
With strict limits for sustainable biofuels and carbon sequestration of 200 Mt a year, large volumes of both molecules must be brought together for green fuel synthesis for aviation, shipping and the chemicals industry, but are rarely co-located.
151
Fabian Neumann @fneum.bsky.social · 11/04/2025
Our team of @tuberlin.bsky.social researchers showed that combined infrastructure for hydrogen and CO₂ pipeline networks could reduce Europe's energy system costs by up to 5.3%, or approximately €41 billion per year. But development requires careful planning across borders and sectors.
