A project that creates value and competitiveness and contributes to energy transitions
In response to the i-Demo call for projects, P4Hydro was selected by bpifrance to develop a new high-efficiency power transmission technology to produce or use energy more efficiently in the world of tomorrow. P4Hydro aims to improve the energy performance and controllability of off-road machines and wind power transmissions.
A high-performance piezohydraulic transmission
The piezohydraulic transmission developed as part of the P4Hydro project has two objectives:
- Improve the efficiency of hydraulic transmissions and the controllability of off-road machines
- Increase the productivity of wind turbines by optimizing their operating range
These 2 objectives will be achieved by developming a piezohydraulic wind generator and a high-efficiency hydraulic system, equipped with ultra-fast piezohydraulic valves.
As for the wind turbines, the generator, once its efficiency improved thanks to this new power transmission system, will be installed on a new generation wind turbine from Provence Eco Energie.
A 5-year project
The P4Hydro project began in 2023 and will progress until its completion in 2027. Key moments are already punctuating this project, such as:
- March 2023: launch of the project during a day bringing together all the partners in La Ciotat
- July 2023: delivery of ultra-fast valves developed by PYTHEAS Technology to Poclain Hydraulics
- September 2023: completion of the first tests of the power electronics developed by the Ampère laboratory
- September and October 2023: installation of the hydraulic motor demonstrator at POCLAIN
