The TwinPower project, led by Scientema, is a direct follow-up to the Green River project, with the aim of disseminating its results. The aim is to create a digital twin of the Honfleur demonstrator of various energy recovery sites, to optimise energy recovery technologies, and to help in the decision-making process for technical adaptation to specific customer needs.

This involves digitising environmental analysis modules (air quality, water quality, turbidity), in particular through technical and engineering missions in marine or river environments (bathymetry, reconnaissance, species counting), to assess the feasibility of this type of multi-energy platform. This digital twin will make it possible to consider the possibility of integrating electric recharging interfaces for drones, bicycles, cars and boats, powered according to the energy available.

The interest of the project lies in its capacity to propose innovative solutions, responding to the public desire to promote renewable energies and to carry out energy recovery operations in complex natural environments. The digital twin developed will be adaptable to various energy recovery sites, depending on the data specific to each study site.

The digital twin is designed to model a floating energy recovery platform. It is based on a multi-physics approach to provide a powerful decision-making tool. Environmental forcings (sunshine, waves, currents, wind) and energy recovery systems (solar panels, wind turbines and tidal turbines) have been modelled and validated independently. The models incorporate real-time data and advanced sensors to improve the accuracy and relevance of the simulations.

A nautical drone is being developed to demonstrate the feasibility of localised use of the energy produced by the float. The drone will carry out regular bathymetric surveys, move autonomously and recharge without human intervention. It is equipped with sensors to collect environmental data and is designed to navigate in specific areas of Honfleur harbour.

• Development of the Digital Twin: BUILDERS led the multi-physics modelling of the floating multi-source platform to create a decision support tool. The models were validated and enhanced with real-time data and advanced sensors.

• Acquisition of the Nautical Drone: BUILDERS took part in drawing up the specifications for the nautical drone, defining the technical and operational requirements. The drone is designed to carry out bathymetric surveys, move autonomously and recharge without human intervention.

   

The project has a total budget of €618,543.

The TWIN POWER project is funded by the CPIER Vallée de Seine - ADEME, Région Normandie and Région Île de France are providing €344,153.
