Thermodynamic analysis of a geothermal district heating system
Thermoeconomic analysis is considered a useful tool for investigators in engineering and other disciplines due to its methodology based on the quantities exergy, cost, energy and mass. This study deals with an investigation of capital costs and thermodynamic losses for devices in the Balcova Geothermal District Heating Systems (BGDHS). Thermodynamic loss rate-to-capital cost ratios are used for ...

Model-based decision support in energy planning
Models have become standard tools in energy planning. Fast computers and ever improving optimisation packages now allow us to solve problems within a few minutes that were out of range 20 years ago and that 10 years ago could only be solved in several CPU-hours. Fully interactive data bank systems with standardised user interfaces and on-line data access support easy modifications and adaptations ...

Investigation of a hybrid solar and geothermal driven absorption cooling system for district applications
In this paper, a new hybrid geothermal and solar driven absorption cooling system (ACS) is proposed for low–temperature district energy applications. Two approaches are proposed in this study, namely: a) a new model for determining the specific entropy values of LiBr–water solution and (b) two new energetic and exergetic parameters, namely geothermal contribution index and solar contribution ...

Energy and exergy analysis of a 16–MW combined cycle district heating system with performance improvements
Results of an energy and exergy analyses performed on a 16–MW University district heating plant located in the Northeast USA are presented in this paper. Unlike past studies, this paper uses actual data to assess CHP plant performance for all the 8760 h in a year (2011). A system of such complexity, considering the large volume of data available and large variations in system load, has not been ...

Technical issues in low to medium-temperature district heating
Low-temperature district heating permits the use of energy resources formerly discarded or could not be claimed. However, its investment may be capital intensive because of equipment oversizing and temperature peaking required by conventional equipment. In classical design philosophy, flow is minimised in order to compensate some of the oversizing costs and to improve the utilisation rate of the ...

An anchor tenant approach to network management: considering regional material and energy flow networks
In a similar way to several other areas of management, approaches to networking and network systems have received increasing attention in the literature on corporate or industrial environmental management. It has been acknowledged that the life cycles of products and their resource use, waste and emission generation are affected by or affect many different companies and other societal actors such ...

Utilisation of deep geothermal energy for heating purposes
The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

Thermodynamic assessment of an integrated system for cogeneration and district heating and cooling
A thermodynamic assessment is reported of a proposed system, for which advanced engineering designs have been developed for integrating cogeneration with district heating and cooling. The system was developed by Edmonton Power for the city of Edmonton, Alberta, Canada. Energy and exergy analyses are used to attain a more complete thermodynamic understanding. The results provide a better ...

What does decarbonising the UK actually mean?
How can we get further up the road to decarbonising the UK, and what can we learn from other countries? When the North Sea gas was found by accident at a water well in the German city of Hamburg in 1911, it is doubtful they knew that the discovery would be the toast of British energy companies in years to come. North Sea gas, extracted from the many oilfields that have been discovered in the ...

District heating reduces carbon footprint – Case Study
District heating is a system for distributing heat generated from a centralized location for residential and commercial heating requirements. The heat is often obtained from a cogeneration plant that burns fossil fuels, but increasingly these plants are transitioning to biomass. According to recent research, district heating is one of the cheapest methods of reducing carbon on the planet and has ...
