Who we are?

Engineers committed to a clever energy transition

Our belief

Because wind & solar are non-controllable energy sources showing poor global environmental impact, we believe that the world needs another affordable clean energy source that is also minimally invasive, clean and predictable.

Tidal power has such benefits and we want the world to know it.

Our mission

HydroQuest is on a mission to make the force of rivers & oceans a premium source of energy to the world, allowing countries to rely on a truly clean, renewable base energy available on earth.

Our main assest is the capability to build a whole project, from its feasibility to its exploitation.

Our values

Technologies & integration

HydroQuest believes that full ownership is the key to success. This is why we have built a team that collectively owns a comprehensive scientific & industrial expertise in hydraulic, electrical & mechanical engineering, with the ability to fully handle power production projects.

Being “Internasocial”

While addressing a demanding global market, HydroQuest embraces a local approach. Wherever it operates, we aims at developing local jobs & wealth by allying with local partners.


Even though marine power already claims the lowest carbon footprint of all energy sources, HydroQuest commits to further reduce its environmental impact by sourcing locally, recycling and reusing parts at the largest possible scale.

A strong & deep team

HydroQuest collectively owns a comprehensive scientific & technical expertise in hydraulic, electrical & mechanical engineering, with the ability to fully handle power production projects.


“We have the best turbine, a team of warriors and we’re gonna nail it!”

2010 – Inception in Grenoble, France

At the heart of the French’s hydroelectric power scientific cluster, HydroQuest was born with technologies inherited from the CNRS & INP Grenoble.

2013 – First river turbine deployed

A world first, HydroQuest deploys with EDF the first river current turbine. The farm is connected to the local grid of an isolated village in Guiana, located in a difficult Amazonian environment.

2015 – Industrial partnership with CMN

HydroQuest leads a series A and welcomes CMN Constructions Mécaniques de Normandie, naval shipyard in Cherbourg, as a premium shareholder. Objective is to build together marine current turbines for the OceanQuest project. At the same time, HydroQuest wins the Grand prize for Energy Transition awarded by Usine Nouvelle magazine, presented by the French Commissioner for Investment Louis Schweitzer.

2016 – Kick off OceanQuest 1MW

HydroQuest enters into the OceanQuest project with the goal to design, assemble and test a breakthrough 1MW tidal turbine.

2020 – OceanQuest 1MW celebrates its first year of operations

The OceanQuest turbine shows superior robustness and performance in real conditions. The success opens the door to the development of a larger capacity turbine and to pre-commercial project developments.
