London Carbon Scenarios

In February 2006, Carbon Descent delivered a report for the London Energy Partnership assessing how London could meet its carbon reduction targets for 2026. The study included the development of an energy and carbon model of London, an analysis of a range of different technologies from large-scale combined cycle gas turbine (CCGT) CHP to ground source heat pumps and a detailed cost analysis of the five possible scenarios.

The five scenarios were:

  1. Large-scale CHP led
  2. Micro-CHP led
  3. Renewables led
  4. Insulation and Energy Efficiency led
  5. Hybrid, a combination of the above scenarios

All of the scenarios involved persuading private householders to make changes to their homes, either through the installation of insulation and energy efficiency measures, the integration of renewables, the use of micro-CHP systems or, in the recommended scenario, connection to district heating. As the most economically viable choice, this scenario was considered the easiest to implement. However, the initial development of heat networks will most likely be in the areas of new build and existing social housing where it is easier to influence outcomes. Once these have a track record of providing reliable and affordable heat, these could be rolled out to existing stock.

Following a cost/benefit analysis we identified scenario five - the hybrid solution - as the preferred scenario following a cost benefit analysis.
