For the past few years there’s been a sub-genre of studies trying to pretend that making hydrogen in one place and using pipelines to move it to other places is better than just moving the electrons using HVDC transmission. It’s the Oxford Institute for Energy Studies’ turn to get it wrong, although they are less wrong than preceding efforts.
A year or so ago I looked at a couple of the first papers, and some things leapt out at me. The papers were 2018’s Relative costs of transporting electrical and chemical energy by Saadi et al and 2021’s Cost of long-distance energy transmission by different carriers by DeSantis et al.
