Making hydrogen usage more safe

ID: F1601-09

As a power provider, hydrogen inspires a great deal of enthusiasm and more than a little wariness. a task addressed security problems related to the usage of hydrogen technologies. Hydrogen fuel cell (HFC) technology will initially be commercialised for market-ready applications such as backup energy supply, portable power generation and powering of materials handling automobiles. These programs generally need, by nature or for safety reasons, that hydrogen systems be used inside. However, current regulations, codes and standards (RCSs) are extremely incomplete regarding the practical requirements of security requirements inside. Addressing the safe indoor usage of HFC systems for early markets had been the primary objective of the project. The project desired to supply scientific and engineering understanding for indicating cost-effective means to control dangers, and to develop state-of-the-art security guidelines. It addressed understanding gaps regarding interior hydrogen accumulation, vented deflagration and under-ventilated jet fire. The created knowledge should be translated into security tips, including modern engineering tools supporting their execution. Recommendations should be developed for advancements in the EU and worldwide RCS frameworks to support the safe introduction of HFC in very early markets. Task partners sought to enhance understanding of hydrogen dispersion and accumulation in confined areas. Work centered on a room-like enclosure of typically a few tens of cubic metres with normal ventilation. Based on current and new analytical and numerical models, partners worked on determining characteristic regimes of hydrogen dispersion. Parameters such as the size of the venting location, the size of the enclosure area and the leak flow rates were taken into account. A number of experiments had been carried out to study vented hydrogen–air deflagrations and the interplay between hydrogen–air and enclosure parameters with respect to overpressure effects. Another task was to perform experimental and numerical studies on hydrogen jet fire characteristics. Focus was placed on parameters such as self-extinction, re-ignition, radiation and flame length from outside hydrogen jet fires. Feasible security methods should be given in a tips document with important rules for indoor hydrogen use in the designs. Additional safety products should be proposed whenever sizing techniques are maybe not enough to respect the safety rules.

    Efforts to significantly boost the usage of renewable power are burdening power grids, leading to increased financial and ecological issues. An effort has created systems and methods to realise low-energy districts. Renewable energy supply fluctuates, and matching its demand and supply is becoming all the more challenging. Smart energy management systems and energy storage space systems are required to accommodate a big share of renewable energy in current energy infrastructure. A project set off to increase the use of on-site renewable power at region level by matching its power need and supply. Undertaking partners began by categorising different district kinds and analysing their different load profiles. They then mapped the gear that can be utilized in a district and examined their overall performance. Thermal storage space and smart control are key components of concept. Thermal storage enables a control system to match the supply and need of heat. Thermal storage technologies had been designed following research on novel storage methods. Team members developed a smart power management system to match supply and demand of electrical energy and temperature at the same time. A full-scale demonstration was successfully carried out by setting up the system in 106 dwellings and 9 commercial spaces in an innercity region under development. A simulation tool to evaluate new types of energy systems for existing and new areas was also created and implemented. To make the developed system appealing to end users and meet their increasing energy demands, the group developed a set of novel business models. They are all based on the freedom of the energy consumed or created within the district, and are incorporated into the system. The project envisioned a sustainable community that strives for financial, environmental and social stability. With fossil fuels expected to run out and the need for energy to boost, current energy supply systems are undergoing radical modifications. It helped enhance a number of types of thermal storage technologies to handle the variability of renewable power. In doing therefore, it demonstrated just how to fully exploit the potential of renewable energy.

        The emerging industry of spintronics, often called magnetic electronics, includes both electron cost and its intrinsic angular momentum (spin) that imparts a magnetic area. Spintronics is producing unique electric and magnetic functionalities and innovations mostly driven by the finding of brand new materials. These promise to meet the future demands of information and interaction technology (ICT) devices — lower power consumption, lower cost and smaller size.
        Scientists are on the method to develop unique materials that demonstrate tuneable spin-transfer efficiency at the interfaces. A lot of the individuality of products employing organic active materials and inorganic electrodes is in the wide range of interactions at their interfaces. This is in component due to the wide range of possible molecules that are mainly unexplored. Innovative materials with interfaces that allow control of spin polarisation through chemical tailoring and electric interfacial tuning have been fabricated. While the former method allows selecting spin direction during sample fabrication, the latter allows changing it during unit procedure, thus resulting in a reconfigurable procedure.
        On the method to fabricate laboratory and commercial products with desired magnetoresistance values one of the major achievements was to identify magnetoresistance at high voltages. This started brand new possibilities of utilizing spin-polarised companies at the operating voltages of organic light-emitting diodes or of organic field-effect transistors. Natural spintronics is therefore being exploited for the very first time in these two ICT applications that are commonly used in display and illumination sectors.
