Electric machines and recyclable magnets: cutting-edge technologies to save material

The IFPEN Transports Energie and Énergies du futur (CEA-Liten) Carnot Institutes pooled their expertise for the Melchior project (Machines électriques dans une chaîne de valeur orientée vers le recyclage, or Electric Machines in a Recycling-Oriented Value Chain), conducted from 2022 to 2023 and aimed at developing an electric machine prototype based on recyclable magnet technology. This prototype significantly reduces the quantity of magnets habitually used and its innovative architecture facilitates recycling while guaranteeing excellent performance.

Geothermal plugging: what are the mechanisms and what are the levers for action?

Over time, high-temperature geothermal sites can experience plugging problems. The cause: extremely fine clays in the reinjection water, which progressively reduce the permeability of the underground environment, despite the treatments applied to the surface water. Thesis work has shed light on the mechanisms involved, and provided a glimpse of the means of action that will enable injectivity to be maintained.
