Geochemistry of Geothermal Fluids Workshop

University of Miskolc – Hungary – 26-27 October 2017

Sharing the knowledge and technology of geothermal energy is cruical for the further development of this resource. This workshop brings together the running geothermal projects funded by the Horizon 2020 programme of the European Commision. The aim of the workshop is to provide a glimpse to the geochemical aspects of geothermal fluids, promoting cross-fertilisation between different projects, providing a forum for the exchange of scientific knowledge and facilitating synergies between the projects.

Ben Laenen

Ben Laenen graduated as a geologist in 1992 and obtained a PhD in Sciences – Geology in 1997 at the Catholic University of Leuven (Belgium). His PhD thesis dealt with the geochemical signature and origin of sequence stratigraphic cycles recognized in the Boom Clay, a Rupelian clay deposit that outcrops in North Belgium. During his PhD, he specialized himself in the sedimentology, the chemical and petrographical characteristics of unconsolidated sediments and organic geochemistry. After his PhD, Ben Laenen worked 2 years as a post-Doc at the University of Köln (Germany). He studied secondary oil migration in the Bashaw Reef complex (Alberta, Canada). Since 2000, Ben Laenen is employed as a researcher at VITO. He started as junior researcher in the Raw Materials group of the Energy department, mainly working on GIS related project, data management and 3D modeling of the subsurface. From 2006 till 2010, Ben Laenen worked as project leader in the Resources group. He  planned  and  coordinates  projects  in  the  fields  of  geological  exploration,  gas-  and  CO2-storage, waste conversion using CO2 and geothermal energy. In September 2010, he was promoted to position of research coordinator. He is now responsible to define and elaborate the strategic research programs of VITO in the fields of deep geology and geothermal energy.

At the ICGR her work covers research within all geochemical topics associated with the exploitation of deep geothermal energy as well as aquifer thermal energy storage (ATES) systems. The focus of her work group “Geofluids” within the ICGR is on understanding and controlling scaling but also on issues of corrosion, and on environmental aspects associated with the exploitation of geothermal energy. For two years she is also guest lecturer at the Freie University of Berlin (FU) at the Department of Hydrogeology.


Chris Rochelle

Chris Rochelle, BSc (Hons) Chemistry with Geochemistry (Leicester University), PhD Geology (Leeds University) is a Senior Geochemist with over 30 years research experience into various aspects of the geochemistry of fluid-rock interactions. Much of this work relates to ‘Energy’ – either in terms of energy supply (e.g. geothermal systems, thermal energy storage, gas hydrates), or the subsurface disposal/storage of waste materials from energy generation (e.g. CO2 capture and storage, radioactive waste). His research interests centre around geochemical process understanding, and to facilitate this, he uses the experimental facilities at the BGS, in particular the Hydrothermal Laboratory. Current geothermal interests include: leading the UK part of two H2020 projects (CHPM2030 – combining heat power and metal extraction; and GEMex – European-Mexican geothermal co-operation), helping lead the geochemistry task in the developing Krafla Magma Testbed (KMT), and contributing geochemical understanding to a new deep, engineered geothermal demonstration project in Cornwall, UK.

Jörg Zotzmann is a chemist and has obtained his PhD in the field of Organic Chemistry from Leipzig University in Germany. His research focussed on organic compounds with medicinal interest as well as multifunctional polymers. He holds a MBA degree from Potsdam University with specialisation on project controlling. Since he started research at the GFZ, his interest concentrates on the chemistry of geothermal fluids in general and scaling in particular. In the GFZ fluid-chemistry lab Jörg conducts research on scaling and scaling inhibitors by applying experimental and analytical techniques under high pressure/high temperature conditions. In 2016 he was assigned the administrative manager of the H2020-SURE project.
