Towards cleaner and more fluid cities

Engie participated in the InOut Exhibition for the second year in a row, and was an event partner this time around. With input from Engie, we took stock of two issues that French energy suppliers grapple with daily: green mobility, and the reduction of city congestion.

 Improving the flow of city traffic, and promoting the development of energy-efficient solutions from an environmental perspective that are relevant to the mobility sector: these are two of the many challenges that France’s #1 energy supplier hopes to address in the coming years. To consolidate its position as “energy transition leader”, both in France and around the world (the company operates in 70 countries), Engie’s solutions must also be applicable to mobility.

Relieving city congestion

Faced with an exponential and sustainable increase in the urban population, and the phenomenon of metropolitanization, cities are increasingly affected by road congestion. To counter this problem and enable local authorities to respond to it, Engie has created “the Livin’ solution”. This concept was designed to connect urban infrastructure, and more precisely, transportation infrastructure (street lights, traffic regulation, safety, parking, environmental monitoring, recharging points for electric vehicles, etc.), so as to be able to control them in real time. It can even anticipate situations in order to optimize efficiency during high-frequency events (e.g. congestion, pollution spikes) as well as during unpredictable events (e.g. accidents).

Designed by Engie Ineo, one of Engie’s subsidiaries, the program is already used in France, Italy, the United States and Brazil. Corentin Chartier, project manager at Engie Ineo Atlantique, tells us about a few of the program’s popular features. Namely, its ability to display and program messages during pollution spikes that let people know that public transportation is free, inform users of accidents via variable-message signs, create maintenance tickets for defective equipment, and synchronize traffic lights. “In Nantes, we installed sensors that keep track of each bus’s location; and traffic lights are automatically synchronized so that the buses are given the right of way,” explains Corentin Chartier. He continues, “In Baule, renovating all the street lights, which were a major source of energy consumption, resulted in energy savings of 70%.” An energy-efficient move that is just the beginning; the city will soon develop and implement ways to optimize the operation of its street lights based on various parameters, therefore increasing its savings even further. The program is scalable and oriented toward “UX urban design”, which means that the various cities can use it to greater or lesser degrees as they see fit. “It’s an evolving tool whose purpose is to adapt to the needs of cities and their inhabitants,” says Corentin Chartier.

Green mobility or bust

In addition to solutions that enable a smarter and more inventive road infrastructure management, green mobility is also a central focus of France’s leading energy supplier. To “take the reins of green energy” and apply it to mobility, Engie is focusing on the hydrogen electric engine. The hydrogen engine’s high storage capacity is advantageous when compared to intermittent renewable energies. Wind turbines, for example, continue to produce energy even when none is needed; this energy must therefore be stored to use later. In addition to the hydrogen engine’s high storage capacity, it also offers environmental benefits: the engine in action emits nothing but…water! “It makes geographical sense, as the energy is produced locally and is environmentally friendly,” summarizes Sebastien Ramos, the Engie representative in Brittany.

The hydrogen electric engine was given pride of place at the 2019 InOut Exhibition, as evidenced by the many demonstrations, conferences, and workshops on the topic. The hydrogen electric motor is one of Engie’s flagships, but not the only one: “Even though we are focusing on hydrogen, we don’t believe that there is one single solution. We are working on all forms of clean mobility, including biomethane,” says Sébastien Ramos. A comprehensive energy transition strategy based on cutting edge technology, focusing on locally-produced and locally-used resources, and of course… solutions adapted to the mobility and cities of the future.
