Ecluse


The ECLUSE steam network has been operational in the port on the left bank of the Scheldt since March 2019. It is the very first large-scale industrial steam network in the Port of Antwerp. ECLUSE is a collaboration between Indaver, SLECO, Fluvius, Fineg, Water-Link, and the Scheldt Left Bank Corporation (MLSO). 

Sustainable steam network

ECLUSE supplies steam to five companies at the port on the left bank of the Scheldt. This steam is generated by burning waste and supplying the heat the companies need for their production processes. The delivery of steam means the companies no longer need their own kettles to generate steam for their production processes. Which reduces CO2 emissions by at least 100,000 tonnes. ECLUSE supplies at least 5 per cent of all green heat produced in the Flanders. This is how ECLUSE provides an important contribution to achieving the Flemish climate objectives.

How does ECLUSE work?

The steam departs the waste-to-energy plant via a specially laid network of insulated pipes to five companies in the surrounding area:
  • Ineos Phenol
  • ADPO
  • Lanxess Belgium
  • Monument Chemical
  • Ashland Specialties Belgium

The steam is transported at a constant pressure of about 40 bar and a temperature of about 400°C.

The hot water returns via a condensation pipe back to Indaver and SLECO where it is reused. The condensation pipe first supplies heat to the DP World offices. The entire pipe network is about 5 kilometre in length of which the largest part is above ground (± 4 kilometres).

You can find more detailed information about ECLUSE on the project website.

Award-winning project

ECLUSE has already been acclaimed nationally and internationally and, in the meantime, has received various prizes, even before its first official steam supply:

  • 2016: Sustainability Award from the Antwerp port community
  • 2017: Belgian Energy and Environment prize
  • 2018: CEWEP award

Ecluse - key figures

  • pipe network around 5 kilometres in length
  • reduces CO2 emissions by 100,000 tonnes a year
  • constant pressure of around 40 bar
  • 400°C
  • 160 MW thermal power
