« Stock-air 2 » project aims at developing and controlling a technical solution where an air-to-air heat pump is coupled to a thermal storage made of Phase Change Material (PCM) in order to erase the electricity demand during the peak hours between 6 p.m. and 8 p.m. This technical option is relevan

Needs of cooling and refrigeration systems absorb more than 15% of the total worldwide electric production, as requested and used in many fields such as food and pharmacy industries, buildings, transports.. Almost all fridge machine use the classical principle of compression/depression of gases, but

Though the Huntorf compressed air storage was a success, CAES did not experience the rapid development expected in the 80’s. However, when their power range is considered, they appear as the only credible alternative to pumped hydroelectricity plants. Recent changes in the technical and economical

It is expected to have a growth of the rail traffic in the coming years which would face a growing energy consumption connected to: the big socio-economical development expected indicates the increasing fourfold of the travellers’ demand on the horizon of 2030. Also, as far as the goods transportat

The air hybrid engine absorbs the vehicle kinetic energy during braking, stores it in an air tank in the form of compressed air, and reuses it to propel a vehicle during cruising and acceleration. Capturing, storing and reusing this braking energy to give additional power can therefore improve fuel

The buildings account for today approximately 42% of the final total energy consumed in France and 23% of the CO2 emissions. "Le Grenelle de l’Environnement" took the measurement of this effect, and laid down very ambitious objectives for the energy renovation: reduction of energy consumption of 20%

The development of Lithium-air batteries represents an important breakthrough in batteries because for the first time an all electric vehicle with a range comparable to the traditional petrol driven ICE (> 500 km) car can be envisaged without recharging. A preliminary project of short duration (ANR

The aim of the STAID project (Seasonal Thermochemical heAt storage In buildings) is the design and evaluation of a compact seasonal thermochemical heat storage system for building application. The thermal energy storage material is a zeolite/magnesium sulphate composite; one task of the project deal

Since the 90’, rechargeable Li-ion batteries are the most widely used for energy storage in portable devices. However, today’s most performing cells have almost reached their intrinsic limits while the demand in terms of performances and safety is still increasing. Commercially available batteries m

The aim of the project is the increase of the energy density of the lead-acid battery replacing the conventional lead alloy current collectors with conductive carbon honeycomb composite ones. In the beginning of the project the conductive carbon composite material will be developed, optimizing its c
