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 …

Turning exhaust gases into electricity, an innovative prototype

high temperature fuel cell

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 …

Digital technology, the gap in Europe’s Green Deal

Europes green deal

Fabrice Flipo, Institut Mines-Télécom Business School Despite the Paris Agreement, greenhouse gas emissions are currently at their highest. Further action must be taken in order to stay under the 1.5°C threshold of global warming. But thanks to the recent European Green Deal aimed at reaching carbon neutrality within 30 years, …

Datafarm: low-carbon energy for data centers

Datafarm

The start-up Datafarm proposes an energy solution for low-carbon digital technology. Within a circular economy system, it powers data centers with energy produced through methanization, by installing them directly on cattle farms.   When you hear about clean energy, cow dung probably isn’t the first thing that comes to mind. …

Astrid: a nuclear project goes up in smoke

ASTRID project

The abandonment of the Astrid project marks a turning point for France’s nuclear industry. The planned nuclear reactor was supposed to be “safer, more efficient and more sustainable”, but therefore required significant funding. Stéphanie Tillement, a researcher at IMT Atlantique, has studied how Fukushima impacted the nuclear industry. Her work …

Unéole on our roofs

Unéole

We know how to use wind to produce electricity, but large three-bladed turbines do not have their place in urban environments. The start-up Unéole has therefore developed a wind turbine that is suitable for cities, as well as other environments. It also offers a customized assessment of the most efficient …

Guillaume Balarac, turbulence simulator

Guillaume Balarac

Turbulence is a mysterious phenomenon in fluid mechanics. Although it has been observed and studied for centuries, it still holds secrets that physicists and mathematicians strive to unlock. Guillaume Balarac is part of this research community. A researcher at Grenoble INP (at the LEGI Geophysical and Industrial Flows Laboratory), he …

Fukushima: 8 years on, what has changed in France?

Fukushima was the most devastating nuclear disaster since Chernobyl. The 1986 disaster led to radical changes in international nuclear governance, but has the Japanese catastrophe had the same effect? This is what the AGORAS project is trying to find out. IMT Atlantique, the IRSN, Mines ParisTech, Orano and SciencesPo are …
