In search of a future for fast neutron reactors

In August 2019, it was announced that the Astrid project for sodium fast reactors (SFR) was to be abandoned. In late 2020, Stéphanie Tillement, a researcher at IMT Atlantique, analyzed the rationale behind this abandonment in an article for I’MTech. But what is the global situation? Does this technology still have a …

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

hydrogène décarboné carbon-free hydrogen

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, …

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 …

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 …

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. …

The worrying trajectory of energy consumption by digital technology

energy consumption

Fabrice Flipo, Institut Mines-Télécom Business School In November, the General Council for the Economy, Industry, Energy and Technology (CGEIET) published a report on the energy consumption of digital technology in France. The study draws up an inventory of equipment and lists consumption, making an estimate of the total volume. The results …

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 …
