Besix Powers Its Largest Tower Crane With Green Hydrogen

For 4 weeks, the tower crane at the BESIX Equipment Department in Sint-Pieters-Leeuw (Belgium) ran on green hydrogen. Why and how? Decoding.

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.

This initiative by BESIX Environment allows the BESIX group to continue its trajectory in the green hydrogen market, making it an effective player in developing this new energy vehicle from production to use.

Various parameters were assessed during these four weeks, among them generator supplier reliability, facility security, employee training, transport sustainability, and security of green hydrogen supply.

“This sustainable alternative to noisy and polluting diesel generators is one of the tracks we are following right now to reduce our emissions, but it is not the only one. This is only the beginning. We shall continue to speed up our energy transition together with our partners, customers and suppliers” François Campus concludes.
