Study of the energy transition in urban environments by hydrogen vector

L’institut FEMTO-ST (Franche-Comté Electronique Mécanique Thermique et Optique – Sciences et Technologies, UMR 6174), est une unité mixte de recherche, née le 1er janvier 2004 de la fusion de cinq laboratoires francs-comtois, formant ses départements initiaux.

La spécificité de FEMTO-ST est d’associer les Sciences et Technologies de l’Information et de la Communication (STIC) avec les Sciences pour l’Ingénieur (SPI). Son champ thématique couvre en effet l’optique, l’acoustique, les micro nanosciences et systèmes, le temps-fréquence, l’automatique, l’informatique, la mécatronique, en même temps que la mécanique et les matériaux, l’énergétique et le génie électrique.

Les actions de recherche de FEMTO-ST peuvent être fondamentales ou appliquées, et produisent régulièrement un impact socio-économique, dans des secteurs comme l’énergie et les transports, la santé, les télécommunications, le spatial, l’instrumentation et la métrologie, l’horlogerie, l’industrie du luxe.

Le département ENERGIE focalise ses activités de recherche sur la conversion et la gestion de l’énergie. Il apporte ainsi une contribution scientifique majeure et complémentaire aux recherches menées au sein des six autres départements de FEMTO-ST à travers une approche énergétique systémique visant la production d’énergie efficiente, compétitive et respectueuse de l’environnement. Il compte environ 85 membres.

L’ensemble des travaux menés par le département s’appuie sur des approches théoriques (modélisations, simulations) et expérimentales en lien avec des systèmes énergétiques multi-physiques (électriques, thermiques, mécaniques, fluidiques), souvent dans le cadre de partenariats industriels et académiques nationaux et internationaux. Ces travaux sont menés par les différentes équipes du département, mais également en lien, de manière transversale et interdisciplinaire, avec les six autres départements de FEMTO-ST (contrats industriels, thèses, programmes de recherche nationaux et internationaux).

The FEMTO-ST Institute (Franche-Comté Electronic Thermal mechanical and optical - Science and Technology, UMR 6174), is a joint research unit, born on January 1, 2004 from the merger of five laboratories in France, forming its initial departments. The specificity of FEMTO-ST is to combine Information and Communication Science and Technology (STIC) with Engineering Science (SPI). Its thematic field covers optics, acoustics, micro nanosciences and systems, time-frequency, automatic, computer science, mecatronics, as well as mechanics and materials, energy and electrical engineering. FEMTO-ST's research actions can be fundamental or applied, and regularly produce socio-economic impact, in sectors such as energy and transport, health, telecommunications, space, instrumentation and metrology, watchmaking, the luxury industry.

The ENERGY department focuses its research activities on energy conversion and management. It thus makes a major and complementary scientific contribution to the research carried out within the other six departments of FEMTO-ST through a systemic energy approach aimed at efficient, competitive and environmentally friendly energy production. It has about 85 members.

All the work carried out by the department is based on theoretical (modelling, simulation) and experimental approaches related to multi-physical energy systems (electric, thermal, mechanical, fluidic), often within the framework of national and international industrial and academic partnerships. This work is carried out by the various teams of the department, but also in connection, cross-cutting and interdisciplinary, with the six other departments of FEMTO-ST (industrial contracts, theses, national and international research programmes).

The energy transition in urban areas is a major issue given that most people live in urban or peri-urban areas. The urban uses of energy are multiple and concern:
• buildings (heating, air conditioning, lighting, ventilation, etc) for housing (collective or individual), tertiary premises, and small industry,
• individual or collective transport of people and goods.
A variety of energy sources and carriers are involved, including electricity, fuels, and, in some cases, district heating networks. According to the International Energy Agency’s Net Zero Roadmap – 2023 Update, renewable energy — especially solar photovoltaics — is expected to become the main source of electricity by 2050. The report also points to the growing importance of carbon-free hydrogen.
Electricity from renewable sources enables two main types of energy systems: the traditional grid-connected model, which still dominates today, and a newer, decentralized model built around Energy Communities (ECs). These communities can range from being fully independent to partially or fully self-consuming (SC), with or without a connection to the main grid, and with or without energy storage — either in batteries or hydrogen systems. Integrating urban mobility needs further increases the demand for energy storage.
The interdisciplinary project aims to investigate how an Energy Community (EC) in a renovated urban district can contribute to the energy transition through local production of photovoltaic electricity and carbon-free hydrogen. The studies will be based on energy and environmental aspects but will also take into account economic and legal aspects.
During the internship, an existing model of a district powered by hydrogen systems will be modified to include new buildings, new control schemes and new economic and legislative framework. The updated model will be tested on different application test cases in order to evaluate the energetic, environmental and economic performances of the system.
At the end of the internship, guidelines for the sizing energy systems, managing energy use, and shaping public policy recommendations to update legislative and regulatory frameworks on hydrogen use will be proposed.
 

Master 2 or engineering school in science for engineers, specializing in energy, or electrical engineering, thermal engineering.

Programming knowledge (matlab) is a mandatory. Notions of economy will be appreciated
