@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.

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 · Jun 12

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 · Jun 12

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 · Jun 12

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:

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.

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.

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 · Apr 11

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

Fabian Neumann @fneum.bsky.social · Apr 11

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.

Fabian Neumann @fneum.bsky.social · Apr 11

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 · Apr 11

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.

Fabian Neumann @fneum.bsky.social · Apr 11

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.
