MES ENERGY S.A. – member of MESOGEOS S.A. group – participated in the 4th International Exposition “Verde.tec – Environmental Technologies”, which took place on March 18-20. The exhibition is an opportunity to promote the innovations in green technologies, in which participated companies from the fields of Environmental Rehabilitation, Energy Saving, Renewable Energy Sources, Product and Material Recycling, Resources Management, Liquid and Solid Waste Management, “Green” Industry, as well as Electromobility.
In the exhibition, MES ENERGY S.A. presented, among other things, the first commercially available hydrogen-fueled bikes (H2 BIKE), developed to meet today’s needs for ecological transportation. The bikes have an excellent autonomy of 145 km with a single refueling, thanks to their combination of an integrated hydrogen tank with a high-efficiency fuel cell. Some additional features of the bikes are the energy performance of 780 Wh, the hydrogen tank with a pressure of 300 bar, the assisted speed reaching 25 km/h, the minimum carbon footprint of 0.2 g/km, as well as the wide operating temperature range, so that neither heat nor cold affect the bikes’ performance. Finally, the bikes also present the possibility of instant refueling, as, compared to conventional electric bikes, they are refueled with hydrogen in less than 60 seconds, in any hydrogen refueling station. It is worth noting that MES ENERGY S.A. designed, supplied and installed the first Hydrogen Refueling Station in Greece, which is located at the premises of Demokritos in Agia Paraskevi, Attica.
Apart from the hydrogen bikes, the company presented, in the exhibition, its participation in the development of an Integrated Prototype Multivariable Automatic Control System for the Energy Saving in Wastewater Treatment Plants (WWTP). This innovative System addressed the operation of WWTP in dynamic environments by integrating the Model Predictive Control (MPC) method in wastewater treatment. The integrated algorithm of the System takes into account the main cost factors of the WWTP, such as ventilation, pump operation or aerobic digestion, in order to define the optimal actions for the time period defined each time. Some advantages resulting from the use of the mentioned Automatic Control System are the lower operating costs of the WWTP, the minimisation of the energy consumption and of the COD/BOD fluctuations, as well as the possibility for the user to incorporate a schedule and limitations in critical factors.
