Turbo-Brayton for cryogenic applications - A reliable and efficient solution, designed to save energy with applications on maritime and bio-methane liquefaction.

This solution reliquefies natural gas boil-off in LNG (Liquefied Natural Gas) vessels in order to significantly reduce greenhouse emissions during transport.

In the maritime industry, LNG carriers transport LNG from methane-producing countries to consumer countries over very long distances. This natural gas, which is cold in its liquid state, tends to reheat and in part evaporates during transport. This solution reliquefies the evaporated natural gas and keeps it in the container in liquid form. The same technology is used for liquid Bio-methane production or cooling of High temperature Supra-conductive Cable for electricity transportation.

Key features

  • Reduces gas vapors due to boil-off
  • 120,000 metric tons of CO2eq. emissions avoided each year thanks to 20 units


  • 0 maintenance for 5 years and boasts proven efficiency
  • 500 tonnes of LNG saved on a 2-week journey
  • Payback time of the solution is approximately 2-3 years

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
  • Prototype testing in the real world
  • Prototype testing 1:1 in the lab
