Project presentation

The ANTARCTICA project aims to improve energy efficiency on board ships by using solutions for converting waste heat into positive or negative cold as a partial replacement for existing chillers.


EQUIUM uses a thermo-acoustic process to convert heat into cold, with no moving parts, power consumption or greenhouse gases: it is the energy of sound that does the work of conversion. ‘So, with 100 kilowatts of heat at 350°C, we can produce 25 kilowatts of acoustic waves and 50 kilowatts of cold at 5°C’, explains Cédric François (CEO EQUIUM), who sees possible uses […] on board ships… ‘Our subject is above all the energy efficiency of the air conditioning system. Our subject is above all ‘off grid’”, emphasises Cédric François.

Project duration : October 2019 to March 2020

Role of ENSM

ENSM is studying the technical and economic feasibility of the project. It is also looking at the regulatory aspects inherent in implementing this innovative technology on board.
