Speech Title:Towards Sustainable Energy Technologies: The case of Earth Air Heat Exchanger
Abstract:To facilitate the energy transition, it is necessary to develop sustainable energy technologies. The Earth Air Heat Exchanger (EAHE) is such technology, which can reduce energy consumption by a building significantly. This paper gives an overview on the Earth Air Heat Exchanger technologies and their significant advantages and presents recent R&D activities carried out by INSA ICUBE Strasbourg University. In this paper, a study is conducted to quantify the impact of coating soil types on the energetic performance of an earth-air heat exchanger (EAHE). A new numerical modeling based on the finite element method and taking thermal properties of soils as inputs is proposed. The model is validated with experimental measurements of temperature in soil and in the EAHE, at the University of Strasbourg in France.

Presentation Title: Current development and application of fuel cells on ground transport and a life cycle analysis of CO2 emissions from FCV (Fuel Cell Vehicle)
Abstract: As Toyota, Hyundai, etc. car manufacturers have made their FCVs (Fuel Cell Vehicles) on markets, further technology developments for enhancing fuel cell system reliabilities, total energy efficiencies, system power density and driving range are urgently required. By reviewing current progress on fuel cell development and application on ground vehicles, this talk will present existing challenges of fuel cell and relevant systems, and will explain various efforts and possible solutions for improving fuel cell performances and for extending fuel cell’s application on various vehicles. Finally, a life cycle assessment to FCV’s CO2 emissions is demonstrated and compared with conventional ICEV (Internal Combustion Engine Vehicle).

Speech Title: ALCOHOL BASED FUEL
Abstracts: The need for energy is proportional to population, hence increasing everyday with the population growth. Approximately 80% of the energy need is met with fossil fuels and half of it is being used in transportation. Therefore, there is a rapid decrease in fossil fuel resources. Environmental problems, such as climate change and global warming increase significantly due to the burning of fossil fuels. Environmental pollution is a serious problem, it concerns the world and researchers are constantly looking for new sources of alternative energy to overcome its effects. For these reasons, alcohol-based fuels attract attention as an alternative energy source. The interest in using low-carbon alcohols such as methanol and ethanol as fuel increases every day. These fuels can be stored much easier than gaseous fuels and using them eliminates one of the key reasons of global warming. This type of fuel has a higher octane number compared to gasoline. For example, methanol has been used as fuel for many years due to its high octane number; it is often used with high performance in racing cars. Despite the fact that alcohols are hydrocarbon fuels, their emission to the environment is low due to their easy burning. Generally two types of alcohol draw attention, namely ethanol and methanol. Ethanol can be easily produced by fermentation of biomaterials such as sugar beet and sugar cane. Due to the oil crisis in 1973, alcohol began to be used as a fuel in Brazil and alcohol-powered engines have been manufactured and are used to this day. It is also of great importance to use ethanol as an oxygenated compound as an oil additive. Its use for this purpose is particularly common in North America. The design of vehicles working with methanol is different. Methanol is popularly used as a mixture of 85% methanol and 15% petroleum (named as M85) and this mixture, which has been used since 1980, increases the power of the engine from 120 Hp to 130 hp while reducing the distance traveled from 460 km to 325 km. The octane number is high, but the energy density is low. One of the common uses of methanol is its use in fuel cells due to its high H2 content. It is used with great importance in fuel cells instead of direct use in internal combustion engines. Research is ongoing to develop more economical processes to reduce the production cost of methanol. Besides production from biomass, methanol is mostly produced from syngas. Compared to other alcohols, the energy intensity of using biobutanol in internal combustion engines is higher than gasoline.
