    Your post would mean more if a significant amount of our energy production wasnt already renewables and its only going to increase.

    I believe there has been one major instance of a datacentre running on gas 24/7 and some articles where new datacentres will have to do the same.

    I can't speak for that occasion as I don't know the details, but what I can tell you as someone who actually works for a large multinational who owns datacenters and have seen them physically insitu, typically the diesel/gas turbines are installed for regulatory reasons so they can fire them up when there is a grid outage. They are not used for normal day-to-day operation. They don't like running them, not for financial reasons, but it causes more work.

    I'm now waiting for the inevitable "Ohh but you work for them ergo your biased!" No, I don't like them at all, but they are a necessary engineering solution to a engineering backup problem. Batteries can perhaps power a DC for 1-2 hrs. If the grid stays up, they'll never be fired up other than on the proper maintenance cycle to confirm operation. The alternative is that if the grid goes down then all manner of fall out happens from your bank machine not giving you money, train timetables not longer on your phone app….. to your nexflix movie going off. DC's are a modern fact of life. They need to be online 24x7 and anyone who thinks the country could run without them….is probably naïve.

    That said, I'd still get them to pay a premium for (more) than their share of infrastructure upgrades that are necessary due to their existence. that's fair to me. Everyone wins.

    The upper limit to how much energy to fuel will cost in the future. Or a real breakthrough in carbon storage that isn't greenwashing.

    Germans were making synthetic fuel during WWII so it's not new tech. Costs are mainly down to the price of hydrogen, which will be down to the cost of surplus renewables.

    Ammonia is another option for ships and possibly trains.
