Risk assessment of the Groningen geothermal potential

From seismic to reservoir uncertainty using a discrete parameter analysis

Geothermal exploitation is subject to several uncertainties, even in settings with high data availability, adding to project risk. Uncertainty can stem from the reservoir's initial state, as well as from the geological and operational parameters. The interplay between these aspec ...
Further research into seismicity caused by natural gas production from the Groningen field is necessary to improve the assessment of seismic risk and develop means to control and reduce it. Research into subsurface aspects is primarily of relevance to assess the seismic hazard co ...
Energy can be produced from mixing waters with different salinity in reverse electrodialysis (RED). Technological improvements make RED gaining momentum as a technically viable option for baseload renewable energy generation. In this paper a model is presented for three different ...
This paper presents a techno-economic analysis of a deep, direct use geothermal heat system in a conductive geological setting (Groningen, NE Netherlands). The model integrates the previously discussed uncertainties of the initial reservoir state, geological and operational condi ...
Direct use of geothermal energy can present challenges of financial feasibility in a low-enthalpy setting. The average temperature gradients in sedimentary basins make it necessary to reach larger depths for meaningful heat production, thus increasing the drilling cost. Therefore ...
Energy is released when feed waters with different salinity mix. This energy can be captured in reverse electrodialysis (RED). This paper examines experimentally the effect of varying feed water concentrations on a RED system in terms of permselectivity of the membrane, energy ef ...
This paper outlines a method in which the heat production of a geothermal system is controlled in relation to the demand from a district-heating network. A model predictive control strategy is designed, which uses volume measurements in the storage tank, and predictions of the de ...

A fundamental challenge in the successful implementation of large-scale energy storage (LSES) in the Netherlands is the required public support for underground activities of Dutch citizens. In this study the key considerations and perspectives regarding the (financial) participat ...
