The purpose of this project was to gegraphically map heat demand, heat supply, heat ressources and transmission and distributionfacilities in Denmark.

Geographical representations of heat demand, efficiency and supply

The premise was that energy demand and supply, energy savings and new supply, renewable energy resources, as well as associated costs can be mapped in spatial databases called Energy atlases.

Price regulation, tariff models and ownership as elements of strategic energy planning

The hypothesis here was that new technologies will not appear automatically and they do not by design result in a strong socio-economic development.

Strategic energy planning in a municipal and legal perspective

Hypothesizing that heat planning is challenged by outdated and obsolete plans, emerging low-energy buildings, increased waste incineration and surplus wind energy, this part focuseed on the legal aspects of future strategic energy planning.

The role of district heating in the Chinese energy system

The purpose of this project was to analysis the significant energy saving contributed by development of district in the future. This work investigated the technical and economic potential of applying Danish experience with district heating in China especially for the renewable energy integration into district system combined with electricity sector. The objective of this research was to evaluate the relevant energy outcomes in terms of emission reduction, energy mix, technology mix of district heating in Chinese energy system. In the project we introduced a capacity expansion model to find the optimal energy mix of generation capacity in the Chinese power sector and district sector.

Low-temperature energy sources for district heating

This PhD project was finished in January 2015, see the dissertation here. It investigates various sources of low temperature heat, their applicability in national energy systems as well as their potentials for energy savings. This includes geothermal energy but also heat from industrial processes, waste heat from cooling systems in retail and foodstuff and even air-conditioning.

Distributed CHP plants optimized across more electricity markets

The hypothesis of this PhD project was that a transition needs to be initiated from “First Generation distributed CHP” helping only to reduce fuel use through its high efficiency - towards “Next Generation distributed CHP” maintaining this high efficiency but at the same time making (on a macro-economic scale) the integration of fluctuating production from renewable energy sources (RES) less costly by being flexible.

Thermal storage in district heating systems

john2@webkommunikator.dk (Super User) — Wed, 22 May 2013 12:46:32 +0000

The hypothesis was that storage will be a necessity in future energy systems, which to an even higher degree are based on fluctuating renewable energy sources.

Energy Scenarios for Denmark

john2@webkommunikator.dk (Super User) — Wed, 22 May 2013 12:45:32 +0000

The hypothesis was that 4DH and low-energy buildings will contribute to the creation of thermal comfort in the future.

Minimising losses in the DH distribution grid

The losses in DH grids are a major obstacle to the utilisation of renewable heat sources and waste heat.
