Raphaël Chevrier

Armand Pomart trained as a geological engineer. He graduated from UniLaSalle in 2021 after 3 years of work-study training with the Association Française des Professionnels de la Géothermie (AFPG), during which he worked on tools to promote geothermal energy, in conjunction with BRGM, on the geothermal energy observatory, for example. He then took up a position as regional geothermal coordinator for the Ile-de-France region, a mission funded by ADEME and supported by AFPG. In this role, he worked alongside public and private project developers, helping them to implement a wide variety of geothermal projects, and raising awareness among regional players of the technical, economic, regulatory and environmental aspects of this energy source. On behalf of the French association, he monitors, leads and coordinates the industry’s players around structuring topics in deep geothermal energy. Since 2022, he has been co-piloting Alliance lithium, a cluster of French companies invested in geothermal lithium production.

Conference: How much energy does a space launch require?

Fighting the Earth’s gravity – that’s the very principle of a rocket, designed to carry satellites hundreds, thousands, tens of thousands of kilometers into orbit. The payload put into orbit generally represents only one or two percent of a launcher’s total mass. The rest is made up of structures and fuel, spread over several stages. What are the laws of physics involved in rocket launches, and how is energy distributed throughout the various phases of flight? Having chosen to develop Europe’s first reusable mini-rocket, how does MaiaSpace manage the return of the first stage to the planet’s surface? Can environmental impact be reduced in the future? With unprecedented business prospects in the coming decades, managing energy and the use of raw materials will be key to ensuring the sustainability of the space sector.
