This can tip the scale in favor of efuels (as opposed to battery-electric). Just run the electrolysis straight from a windfarm and produce at the rate the windf

  The very low efficiency of e-fuels probably more than outweighs the cost of upgrading the grid. They will be important for sustainable aviation, but anywhere else they don't appear to be economically feasible.

  This is what’s currently happening. It’s windy in some remote places. Connecting those places to the grid is horribly expensive but building a chemical plant there isn’t. That’s the locations where efuels are being made today. Like the Porsche project in Chile. https://newsroom.porsche.com/en/2022/company/porsche-highly-innovative-fuels-hif-opening-efuels-pilot-plant-haru-oni-chile-synthetic-fuels-30732.html https://newsroom.porsche.com/en/2022/company/porsche-highly-...

  An idea that sounds good, but has the problem that efuel production capital expenditure is fixed and high. So once you've built it, you want to run it 24/7 rather than intermittently. I'm very much open to suggestions for "low capex ways to make productive use of 'spare' electricity, preferably reversibly even if efficiency is low".
