||The Government’s recently published heat strategy identifies two pathways for the long-term reduction in Carbon Dioxide (CO2) emissions from energy for heating buildings and provision of domestic hot water:
The Government recognises that in high density urban areas DH is likely to be more cost effective and that in rural areas DH is not a practical solution. This leaves a large proportion of the country where either option would be feasible technically but where there is considerable uncertainty as to which option is preferable from both a cost and CO2 perspective.
- the use of district heating (DH) supplied by a range of low carbon heat sources
- the use of individual heat pumps supplied by a largely decarbonised electricity grid
The Macro District Energy (DE) project has been able to establish the cost of heat supply and the CO2 emissions for a range of characteristic zones which represent the urban and suburban areas within Great Britain
This summary report describes the work packages and their outcomes, and makes recommendations for future work, particularly covering issues found, but not explored, in this project.
