i heard that a couple of german dcs (owned by universities or other research institutions and therefore indirectly by state) do this, but this kinda depends on district heating grid existing and also puts some limits on thermal side, in simplest variant chips just have to run hotter. not to mention that it’s kinda easier to do when you own the entire thing, long term, and can offload some of the engineering and design effort to some intern student writing masters or doctoral thesis. this works in part because when you switch from coal to gas and have district heating using that waste heat, there’s less waste heat from CCGT of equal power, and it’s all gone when you switch to renewables, so there’s a grid that still needs some heat and dc boiler can fill that gap to a small degree. at the same time dc can’t be the only source of heat because demand is seasonal and dc ideally should run 24/7 and while you can get enough storage for daily variation this won’t be enough and some other source of heat is needed. this is why it makes more sense as a long term government backed project
