Green Win, the system set up at the University of Liège, has made it possible to test the operation of large pumps, which can weigh up to one tonne, and pump 300 litres per second in waterways.

00:00Water poses a major challenge in the climate crisis. Europe has 35000 kilometers of waterways like the MERS which flows through
00:11the edge Belgium. Water pumping has a high carbon footprint in northwestern Europe. It accounts for up to 33 percent of the annual
00:19electricity consumption of waterway management and 20 percent of CO2 emissions. At Liège University the European project Green
00:28Wind aims to make water pumping less energy intensive. Second is that there may be tested. Don't make conditions.
00:35Casey real. They don't submersible. So they don't give them to me. It's all fun. You know what I think. I'll pull her. I'm going to do
00:43low. Sure. But what do you do. Do you make the dispositive better made. Estimate. They can't eat it. They never eat. Consume it.
00:52Liège University is a European leader in hydraulic research. The installation simulates situations that you might find on the ground. The
01:06tests were carried out in this tank. There was water and so the pump sucked the water. The water then went into the conduits inside the
01:16laboratory. And we have certain sensors to measure the flow. For example the pressure generated by the pump. Green Wind has a budget of
01:28two point six seven million euros. One point six million of which is subsidized by the EU's cohesion policy.
01:36Five countries are testing how it works under real conditions on 11 pilot sites.
01:49One of which is Stock Pond in Moselle which was modernized with the technical advice of Liège University managed by navigable waterways of
01:59France. It is one of their largest plumbing stations.
02:04La modernisation de la station de pompage a permis de mettre en place cinq pompes immergées qui aujourd'hui sont télé gérables à
02:11distance. Alors on a pu constater un gain de 30 pour cent d'économie d'énergie.
02:17When boats go through the lock thousands of litres of water flow out. The pumping station sends water from the pond back into the canal a
02:26hundred times a year. Elle sert à remplir les temps réservoirs qui est derrière moi. Quand on est en période humide. Et puis quand on est en
02:35période sèche. Le canal qui est situé six mètres plus haut on a besoin de l'alimenter en eau à partir de cet étang. Pour ça on a besoin
02:41d'une station de pompage. The economic and environmental benefits can already be seen across the 11 sites. Researchers hoped to
02:49reduce carbon emissions by 65 tons per year. They've dropped by 200 tons.
