There are no heat pump systems that could supply high grade heat for many (if not most) practical industrial processes done in large scales. You can’t use heat pumps to burn clinker. You can’t use them to heat aluminum for extrusion. You probably can’t even practically use it for dryers in paper mills. The technology you are asking for simply does not exist. This is not to say that it cannot exist, but it’s silly to say that it’s “just” an issue of installing heat pumps.
