What is digital sufficiency?

Digital consumption doubles every 5 years. This is due in particular to the growing number of digital devices and their increased use. This consumption also has an increasing impact on the environment. Digital sufficiency refers to finding the right balance for the use of digital technology in relation to the planet and its inhabitants. Fabrice […]

What do we know about the environmental impact of biocomposites?

Bio-based materials are an alternative to those derived from fossil resources. They have been increasingly promoted in recent years. However, given the recent development of this sector, their real environmental impact is still relatively unknown. Joana Beigbeder, researcher in environmental analysis at IMT Mines Alès, provides an update on the life cycle analysis (LCA) of these […]

Digital simulation: applications, from medicine to energy

At Mines Saint-Étienne, Yann Gavet uses image simulation to study the characteristics of an object. This method is more economical in terms of time and cost, and eliminates the need for experimental measurements. This field, at the intersection of mathematics, computer science and algorithms, is used for a variety of applications ranging from the medical […]

Corenstock Chair: a Trial Cylinder for the Heating Industry

As 2021 begins, IMT and elm.leblanc launched the Corenstock Industrial Chair to address issues in energy and digital transition in the domestic heating industry. What is the objective? Within four years, to present a demonstrator for the hot water tank of the future: more resistant, efficient and durable. Behind this prototype lies the development of […]

Circular economy, environmental assessment and environmental budgeting

To implement a robust and durable circular economy strategy, it is important to assess its environmental impacts. Valérie Laforest and Natacha Gondran, both researchers at Mines Saint-Étienne, explain the reasons for incorporating an absolute environmental sustainability assessment method and the underlying concept of “environmental budgeting“. The lifestyles of our contemporary societies are exerting constant and […]

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 […]

Power-to-gas, when hydrogen electrifies research

Hydrogen is presented as an energy vector of the future. In a power-to-gas system, it serves as an intermediary for the transformation of electricity into synthetic methane. The success of this energy solution depends heavily on its production cost, so IMT researchers are working on optimizing the different processes for a more competitive power-to-gas solution.

Hydrogen: transport and storage difficulties

Does hydrogen hold the key to the great energy transition to come? France and other countries believe this to be the case, and have chosen to invest heavily in the sector. Such spending will be needed to solve the many issues raised by this energy carrier. One such issue is containers, since hydrogen tends to […]

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 […]
