And that doesn't answer my questions. It wasn't supposed to do so, but raise awareness that your questions are already highly relevant in the present and not just a hypothetical future: The UK consumes something on the order of 8 million tons of wood pellets per year. The carbon footprint depends on the source of the wood (eg replacing naturally grown with farmed trees is not a carbon neutral activity). Shipping has to be considered as well. Uninformed layperson that I am, I'd guess power-to-gas would be a superior solution, but it's pretty expensive right now...
