  • At the end of the study, we provide you with a file containing all the data collected, compared and analyzed. A presentation of the chosen solution is also given.

Our values

The three points of honor are :

  • Independence of suppliers: we study and advise on their technologies, but we are not their salespeople.

  • Impartiality: technologies can be selected and recommended to our customers if, and only if, they correspond in every respect to their project.

  • Trust and confidentiality: our files and the information contained and exchanged are strictly confidential. We establish a relationship of trust with both market players and our customers. 

HY-plug's mission is to help connect the right players in the maritime energy transition by bringing end-users and suppliers closer together through its consulting services.
