Regalor is a scientific Coal Bed Methane (CBM) project to explore the natural gas deposits in the subsoil of Lorraine. Regalor focuses on the collaboration of scientists with industry with the aim of promoting the implementation of low-carbon coal bed methane production in Lorraine.

Regalor was initiated in 2012 by the Lorraine Region and is funded by the European Union (ERDF) and the Grand-Est Region. GeoRessources with Solexperts France as subcontractor and Française de l'Énergie are the project promoters.

Solexperts contribution

Development, construction and installation of a gas measurement system for deep wells. The innovative probe can continuously quantify the (dissolved) gases at different depths, especially in the coal seams.

Currently, the Solexpert probe SysMoG successfully measures the concentrations of dissolved gases in groundwater in a 1200 m deep borehole. The quantification of the gas present in the coal layers is an important step for the researchers at the University of Lorraine .

Pilot site

The pilot site in the commune of Folschviller is an experimental site for university researchers within the framework of the Regalor project of the University of Lorraine to clarify the usability of the Lorraine coal gas. Other research projects on the use of the soil and the subsoil for energy storage (e.g. hydrogen) or the storage of greenhouse gases are planned at this site.
