The testing hall, the heart of R&D

A testing hall with 9 “laboratories” is entirely dedicated to testing: the facility is equipped with hydrogen, biogas, bio-LNG testing facilities, industrial ovens furnaces, a Hardware in the Loop bench, a test rig for cooking and catering application, a drones and robots Lab, as well as a prototype workshop. It also houses a gas library where the main gases used for testing (nitrogen, hydrogen, natural gas, etc.) are stored. Outside, demonstrators and prototypes can also be tested, including a piece of equipment, unique in Europe: a 17-meters high experimental building simulating the evacuation of combustion products in chimney flues.


 « This new hall is a major asset in our testing capabilities. With our 19 islands of testing
facilities, ENGIE Lab CRIGEN will be able to carry out physical and virtual tests, in order to develop, optimize, de-risk and industrialize cutting-edge low carbon technologies. It’s also a key asset to increase our collaboration with international partners. »
