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…

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,…

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…

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…

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…

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…

Astrid: a nuclear project goes up in smoke

, ,
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,…
