Job description
The EU aims to have a net-zero greenhouse gas (GHG) economy by 2050. At present, heating and cooling represent around 50% of the final energy use in Europe and are mainly supplied by fossil fuel derived energy. Because sustainable heat is mainly available in summer and demand is high in winter, large scale seasonal heat storage is a key strategy to decarbonize heating in order to achieve EU ambitions. TU Delft leads a large European project that will showcase and develop full-scale application of heat storage (up to 90°C) in geothermal reservoirs using three different technologies: Aquifer, Borehole and Mine Thermal Energy Storage (ATES, BTES, MTES), at 6 different sites in Europe which together represent a relevant range of geological conditions across Europe. In this PD project you will contribute to the development and application of a generic, open-source, high-performance and highly scalable framework to assess the Levelized Cost of Energy/Heat - LCOE reduction and carbon emission reduction costs (CRC) of heat storage in geothermal reservoirs in combination with different heat supply sources.
LCOE generating a sustainable energy economy
Many sustainable heat supply systems are characterised by high capital expenditure and low operational costs. Therefore, an installed capacity tailored at peak demand is not cost effective, while extending the annual operation period is advantageous for meeting energy needs, reducing levelised cost of energy (LCOE) and decarbonisation. Optimal utilisation of sustainable heat requires storing large amounts of heat to account for seasonal supply and demand fluctuations. Various technologies have been proposed for large-scale heat storage in geothermal reservoirs and low temperature storage is routinely applied. PUSH-IT focuses on extending storage temperature ranges to high temperatures. We will tackle remaining barriers for high temperature storage, demonstrate applicability, increase public engagement, and optimise and de-risk operations.
In PUSH-IT we will develop a unified framework for the combined or individual techno-economic assessment of heat storage and geothermal heat sources. One of the challenges for such an approach is the combination of subsurface (geological) heterogeneity and uncertainty with the performance of various technical components of the heating systems in varying climatic conditions. To address this complexity, a team of geological and technology experts will work together to build a framework on open-source code (Python) that is high performant and scalable to comprehensively quantify uncertainties using probability theory. The framework will further be able to seamlessly analyse the techno-economic performance of heat storage systems at any time interval required to capture the system dynamics as dictated by demand-side management. Finally, a simplified user interface will be developed to make the interaction with the underlying code more user friendly and accessible. Input from consortium industry partners on component, operational and other costs will be used to validate the techno-economic models. A strong collaboration with consortium members in industry and academia is key.
