9
Energy density Diversity and continuity of load Scale Low cost of heat production Low carbon heat sources Low distribution temperatures Characteristics of Success
10
Seasonal and daily variances in load Availability and reliability of heat source Compatibility with traditional building services Return temperature control Integration of low carbon sources of heat and cooling into urban heat networks Influence of temperature on suitability and efficiency of low carbon and secondary heat Infrastructure cost Challenges and Opportunities
11
Secondary heat – industrial and natural sources Smart system management – demand and supply side – economic, capacity and carbon drivers Storage – different scales and materials – thermal plus potential integration with electrical systems Integration of renewables into established schemes Building services compatibility – temperature and managing peaks Emissions control to manage & mitigate urban air pollution Cooling systems – innovative solutions and integration with other thermal energy systems 11 Areas for Further Work
