On Wednesday 22 February 2017, Carbon Connect ran a roundtable in Parliament entitled “The Economics of a Low Carbon Gas Grid”, chaired by Callum McCaig MP, James Heappey MP, and Dr Alan Whitehead MP. This was the third of three evidence sessions held as part of the research process for the first report in Carbon Connect’s Future Gas Series. This paper has been produced as a follow up to this. While it was informed by the event it does not necessarily represent the views of those in attendance.
