Decontaminating and treating waste from the steel industry

The manufacture of steel produces mineral residues called steel slags, which are stored in large quantities in slag dumps. These present a dual challenge. On the one hand, they are potentially harmful for the environment and health, and on the other hand they are a useful resource for certain industries. The HYPASS project at Mines […]

Carbon-free hydrogen: how to go from gray to green?

The industrial roll-out of hydrogen production only makes sense if it emits little or no carbon dioxide. Researchers at IMT schools are working on various alternatives to the use of fossil fuels, such as electrolysis and photocatalysis of water, plasma pyrolysis of methane, and pyrolysis and gasification of biomass. Currently, the production of one ton […]

Fuel cells in the hydrogen age

Hydrogen-powered fuel cells are recognized as a clean technology because they do not emit carbon dioxide. As part of the energy transition aimed at transforming our modes of energy consumption and production, the fuel cell therefore has a role to play. This article will look at the technologies, applications and perspectives with Christian Beauger, a […]

Turning exhaust gases into electricity, an innovative prototype

Jean-Paul Viricelle, a researcher in process engineering at Mines Saint-Étienne, has created a small high-temperature fuel cell composed of a single chamber. Placed at the exhaust outlet of the combustion process, this prototype could be used to convert unburned gas into energy. Following the government’s recent announcements about the hydrogen industry, fuel cells are in […]

Imagination: an architect and driving force of transitions

All technology starts with a vision, a tool created to meet one of society’s objectives. Its development path is formed by both human projections and the dynamics of the transformations it generates. It is therefore important to take the time to ask ourselves what we intended to do with digital technology and what we will […]

Hospitals facing a different kind of infection: computer viruses

Hervé Debar, Télécom SudParis – Institut Mines-Télécom [divider style=”normal” top=”20″ bottom=”20″] [dropcap]W[/dropcap]annaCry was the first case of a cyberattack that had a major effect on hospitals. The increasing digitization of hospitals (like all areas of society) offers significant opportunities for reducing the cost of health care while making the care provided more effective. However, with […]

Silicon and laser: a brilliant pairing!

Researchers at Télécom ParisTech, in partnership with the University of California, Santa Barbara (UCSB), have developed new optical sources. These thermally-stable, energy-saving lasers offer promising potential for silicon photonics. These new developments offer numerous opportunities for improving very high-speed transmission systems, like datacomms and supercomputers. Their results were published in Applied Physics Letters last summer, […]

How eco-design earned its place in the corporate world

Natacha Gondran, Mines Saint-Étienne – Institut Mines-Télécom [divider style=”normal” top=”20″ bottom=”20″] [dropcap]I[/dropcap]n the 1970s, regulations were introduced to require companies to prevent industrial pollution. Examples include the Clean Air Act (1970) in the United States and legislation on facilities classified for the protection of the environment in France (1976). Since then, awareness has grown about […]
