How these plans relate to carbonsucking and air travel

In a future world where carbon pollution is priced appropriately to prevent catastrophic climate change, we will be interested in any power scheme that can at low cost put extra carbon down a hole in the ground. Such carbon-neutralization schemes might permit us to continue flying at 2004

levels (while oil lasts). In 2004, average UK emissions of CO2 from flying 1 tCO2e means greenhouse-gas were about 0.5tC02 per year per person. Accounting for the full green- emissions equivalent to one ton of house impact of flying, perhaps the effective emissions were about 1 t CO2e CO2. per year per person. Now, in all five of these plans I assumed that one plan D

eighth of the UK was devoted to the production of energy crops which were then used for heating or for combined heat and power. If instead we directed all these crops to power stations with carbon capture and storage - the "clean-coal" plants that featured in three of the plans - then the amount of extra CO2 captured would be about 1 t of CO2 per year per person. If the municipal and agricultural waste incinerators were located at clean-coal plants too so that they could share the same chimney, perhaps the total captured could be increased to 2tCO2 per year per person. This arrangement would have additional costs: the biomass and waste might have to be transported further; the carbon-capture process would require a significant fraction of the energy from the crops; and the lost building-heating would have to be replaced by more air-source heat pumps. But, if carbon-neutrality is our aim, it would be worth planning ahead by seeking to locate new clean-coal plants with waste incinerators in regions close to potential biomass plantations.
