Since late 2020, the start-up Quick Power Access and the L2EP teams have been working on the innovative concept of the Fatal Energy Box, a device for recovering energy lost during expansion in the gas network.
Improve energy efficiency and reduce energy costs.
Based on the concept of the Fatal Energy Box developed by Quick Power Access, a start-up that innovates in energy production, the L2EP teams are seeking to apply the concept to gas distribution networks. To enable its use by customers, gas undergoes successive pressure reductions in pressure reduction and metering stations. From an initial pressure of between 40 bar and 16 bar for regional networks, it then drops to 4 bar, then to 300 mbar, and finally reaches 20 mbar for private individuals. " Each drop in pressure is accompanied by energy losses in the expansion system, demonstrating the significant potential for energy recovery in the gas network." explains Reda Bakri, lecturer and researcher at L2EP. By recovering this lost energy, the project has two objectives: to improve energy efficiency and reduce energy costs.

In partnership with the start-up Quick Power Access, the L2EP teams are conducting research to develop a demonstrator for a complete gas expansion energy recovery system, using a pneumatic motor to drive an electric generator. Initially tested using compressed air, this demonstrator will then be installed on the gas supply to the Arts et Métiers campus Arts et Métiers Lille. 
" We are responsible for developing the power electronics converter that will interface between the generator and the electrical grid. In addition, we are implementing algorithms that will optimize energy extraction. " adds Reda Bakri.
The prototype produced will ultimately be used for research and educational purposes.
