Do you have a source for north of 70%? I’m not implying it’s incorrect, but I haven’t seen any papers with this level of efficiency for similar proposals.

- nasmorn 4y agoThe 70% is not for conversion into electricity but for total useable energy if the waste heat is used in district heating networks. It can reach up to 80% of the primary fuel used. While that seems worse then simply burning it at the end user you have to keep in mind that you also gain electricity which can be used to drive a heat pump. This is by far the best way to burn gas if heat is needed as a result. https://en.wikipedia.org/wiki/Cogeneration https://en.wikipedia.org/wiki/Cogeneration

Currently, this setup is non-sensical since a lot of other measures should be implemented first, but even currently existing tech is pretty efficient, all things considered. And it only gets better from here.
- brutusborn 4y agoThat paper is awesome, thanks for posting. As well as efficiency, I'm also interested in life cycle analysis of these kind of tech if you know of any good papers.
