In line with current international trends, EREL places emphasis in R&D activities relevant to hydrogen technology, simulation of atmospheric pollutant dispersion in realistic conditions, diagnostic and prognostic meteorological modelling, contribution of anthropogenic and biogenic pollutants to global warming and urban pollution, simulation of underground hydrocarbon and water reservoirs and characterization of nanoporous materials for environmental (gas separations, storage of CO2 and H2) and bio-medical applications (controlled release systems, transdermal drug delivery). In parallel, EREL continues to produce and publish original methods and results in the wider area of computational fluid mechanics, with applications in pollutant dispersion, influence of meteorology and pollutant sources distribution in urban pollution, tropospheric ozone concentrations due to anthropogenic and biogenic pollutants in the Mediterranean area, turbulence simulation, transport phenomena in porous media, and flow and mass transport in multiphase systems. The high R&D performance of EREL is deduced from: (i) its wide experience in carrying out (not only as participating research organisation but also as coordinator) large scale research projects, (ii) the large number of scientific publications in international journals and conferences, (iii) the successfully accomplished contracts of service provision to Public and Private Bodies, (iv) the organisation of international conferences, (v) the participation in International networks and (vi) acting as national representative in various international organisations.

The laboratory conducts mainly applied research and experimental development, arising from the needs of the productive sector, the ties with which have been built through the services offered by the laboratory in a wide field of applications and over a number of years. However, in this effort the laboratory personnel is often faced with the need to answer questions that concern fundamental physical phenomena and expand the current knowledge, especially in the fields of fluid flow, heat/mass transfer and thermodynamics. Therefore, problems are often dealt with at the basic research level, by using suitable analytical methods (modelling and simulation) along with experimental methods.
The specific research areas of SESL are :
The laboratory has been providing reliable and high quality accredited (according to EN ISO/IEC 17025) services to the productive sector, located in Greece but also abroad, as following:

Risk Assessment of Complex Systems

The complexity, the severe consequences, the huge costs and the relative scarcity of catastrophic failures do not permit a standard approach, according to which improvements and relative measures could evolve only by analyzing past experience (real facts) or experiments. The probabilistic analysis and risk assessment approach can (without any historical data) simulate and calculate all possible consequences, and all event sequences that lead to those consequences and the probability of their appearance.
 
Risk Management

Risk Management refers to decision making concerning alternative courses of action with the aim of reducing risks. It usually takes the form of supporting relevant decisions taking into consideration the effect on risk.
