Abstract

Abstract The main objective of this paper is to give an overview of the risks seen in the exploration and production of geothermal energy from the viewpoint of the regulator. The risks are categorised as conventional risks, ultra-deep risks and enhancing factors. These risks are similar to those seen in the oil and gas industry, but the maturity of the geothermal sector in terms of managing such risks is much lower. Another objective of this paper is to discuss how these risks are managed and mitigated by the sector and the supervisor, State Supervision of Mines (SodM). Portfolio operators developing multiple projects, using skilled employees and embracing continuous improvement are seen as the way forward for the sector to grow safely and sustainably. This paper concludes that positive developments have started, but a lot of work still needs to be done to ensure safe growth of the geothermal energy sector.

Highlights

IntroductionEnergie Beheer Nederland B.V. (EBN) is an independent company owned by the Dutch state as its sole shareholder
The use of geothermal energy is predicted to increase significantly in response to the proposed Dutch Climate Act
We only address risks which are of concern to SodM, e.g. risks to employees, civilians and the environment

Summary

Introduction

EBN is an independent company owned by the Dutch state as its sole shareholder It implements the energy policy of the Ministry of Economic Affairs and Climate Policy for the oil and gas sector and for the geothermal sector. The number of geothermal doublets in operation is predicted to be 175 in 2030 and 700 in 2050 Employment in this sector is expected to increase from 240 full-time equivalent (fte) in 2018 to 3400 fte in 2050. The Green Deal Ultra-Deep Geothermal Energy (UDG) (www.greendeals.nl/green-deals/ultradiepe-geothermie) has been signed between the industry, knowledge institutions and the government. The purpose of this Green Deal UDG is to stimulate the exploration and development of ultra-deep geothermal projects. All the above activities focus on increasing the total output of geothermal energy in the Netherlands
