@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 Europeโ€™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.

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 Europeโ€™s biogenic and industrial COโ‚‚ 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 1โ€“10 % across a ยฑ20% import cost range

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

No cost savings beyond imports of 3000 TWh (~90 Mt Hโ‚‚-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.

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! ๐ŸŒฑ

We also find that the combination of both networks remains advantageous when climate targets are tightened toward net COโ‚‚ removal. The COโ‚‚ network allows effective utilization of unavoidable industrial emissions through capture and transport to utilization or sequestration sites

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 COโ‚‚ pipelines transport captured emissions from these clusters to geological sequestration sites, e.g., in the North Sea.

Also: Captured COโ‚‚ from some residual industrial emissions, or biomass for negative emissions, will need to be transported to geological storage sites.

With strict limits forย 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.

Our team of @tuberlin.bsky.social researchers showed that combined infrastructure for hydrogen and COโ‚‚ pipeline networks could reduce Europe's energy system costs by up to 5.3%, or approximately โ‚ฌ41 billion per year. But development requires careful planning across borders and sectors.
