BESIX powers its largest tower crane with green hydrogen

BESIX, at the initiative of BESIX Environment, installed an electro-hydrogen power generator consisting of a fuel cell and an internal battery, with a total installed power of 110 kVA, at its Sint-Pieters-Leeuw site for a four-week test period. This test sought to examine how far an electro-hydrogen group, combined with a battery, can meet the demand for electricity in the specific context of a construction site, in a noise-free and non-polluting way.

For this the hydrogen unit was connected to the largest tower crane on the site. “This tower crane has a peak consumption of up 70 KW, which it needs immediately, making it pretty representative of the consumption of a crane on an average construction site” explains François Campus, Senior Plant Manager at BESIX. “The results of these four weeks of tests will help the Equipment Department, and more generally our BESIX worksites, to make the right choices during our energy transition”, he adds.

This test is part of the strategy of decarbonising the BESIX group’s activities, aimed at offering construction and project site customers increasingly reduced carbon footprints. “This first test, which required us to train a dozen people, will serve as a basis for our ongoing search for solutions to reduce our on-site CO2emissions”, François Campus adds.
