This project is related to the effective deployment and availability of reliable hydrogen sensors, primarily but not exclusively for use in applications using hydrogen as an alternative fuel. The objective is to support and unite stakeholders including sensor manufactures/developers, sensor end-users, certification bodies and independent sensor evaluators having the aim to avoid any hazardous events which could hinder the implementation of hydrogen as an alternative fuel by ensuring the availability and optimum use of low-cost and reliable hydrogen sensors. In doing so a European knowledge hub covering hydrogen sensing technologies, state of the art commercial products, near term applications and correct use of hydrogen sensors will be created. An output from this virtual knowledge hub will be state-of-the-art guidelines on how to select and properly use the best hydrogen sensor for a particular application. In addition the consortium will identify barriers (including those of a market, technical, manufacture-related and regulatory nature) which may hinder the commercialisation and wide spread of hydrogen sensors. Suggestions to overcome these barriers will be formulated in addition to recommendations for integration into ongoing or new RCS activities to be implemented at national and global levels. With the knowledge of these barriers it is expected that sensor manufacturers will be better equipped to design, manufacture and commercialise improved sensors at a lower cost, which are tailored to suit end-user requirements. As a result end-users will benefit from a broader range of effective products to choose from for specific applications. A novel aspect of this project will be co-ordination and joint activities with a US consortium lead by the US Department of Energy (National Renewable Energy Laboratory and Los Alamos National Laboratory) whereby the output will be leveraged by the interaction and knowledge transfer between the European and US consortia.

Clear-up presents a holistic approach to the reducing operational energy use in buildings. By development and novel use of nano-materials it aims to increase energy performance in heating, ventilation, air conditioning (HVAC) and lighting systems, and to improve indoor air quality using catalytic purification. Clear-ups solutions are designed for retro-fitting existing buildings and of course for new constructions. It will achieve this by addressing four key components which control the indoor environment: Windows. Clear-up will advance the practical use of shutters and electrochromic window foils which reduce the building cooling load and along with light-guide technology, reduce the need for artificial lighting. Walls. Clear-up will use photocatalytic materials for air purification and nano-porous vacuum insulation in combination with phase change materials to passively control temperature. Air Conditioning. Clear-up will advance technologies for demand controlled ventilation and improved air quality. Sensors and control provide an underpinning technology for Clear-ups approach. New sensors will be developed, and their use optimised for the operation of smart windows; demand controlled ventilation; and catalytic purification. Clear-up will develop, install, measure and evaluate technological solutions in the laboratory, in a large-scale testing facility and in real world applications. Its approach will be demonstrated at the UN Climate Summit in Copenhagen, 2009. The safety of new materials will be considered; it will propose inputs to standards and environmental product declarations for its technologies. Clear-up will also investigate environmental and economic lifecycles for components and systems. The practical issues of exploitation will be addressed in cooperation with industry bodies ECTP, ECCREDI and ENBRI providing access to large firms and SMEs.

High costs together with concerns for driving range, reliability and safety are still the main hindrance for market adaption of full electrical vehicles (FEVs). ESTRELIA aims to provide building blocks with enhanced reliability and safety at lowered costs for smart energy storage for FEVs.This is accomplished by proposing a modular approach with ultracapacitor power packs with higher density with 50% energy advantage developed by Corning and evaluated by Valeo and Austrian Battery Research Lab. This will be enabled by BMS ICs based on a new concept in the HV-technology from austriamicrosystems enhancing also the modularity of Li-Ion batteries as energy packs. It will for the first time provide a flexible active cell balancing chip set also suited for the high accuracy demanding monitoring of Li-Ion batteries. The BMS ICs and architecture proposed from FHG will be verified on prototypes built by E4V. Tests with new HV test equipment developed by Active Technologies will proof test isolation protections in the environment of several 100s V as present in FEVs. The new BMS IC concept will enable higher efficiency by lower energy loss and improved long term reliability and lower the electronic component costs for BMS of Li-Ion energy packs by 1/3rd.ESTRELIA will also develop new safety sensors which are based on silicon based MEMS approaches delivering enhanced safety functions at lowered cost compared to existing solutions. While the gas sensor will allow detection of very low levels of volatile organic compounds as emitted in thermal overruns of battery packs, the new spark detector concept will enable general safety functions by flame detection from all hazardous events in a FEV.Finally the development of new actuators as low cost power antifuse by FhG together with the new energy management HW (BMS IC) and SW will enable dynamic reconfigurable topologies for the energy storage unit, thus still enabling the functionality of the FEV despite single failing cells.

We report the use of a pre-heated catalytic filter to improve the stability and cross sensitivity of metal oxide gas sensors (MOS). For characterization a pure and gold coated Al2O3 foamed ceramic is integrated into a newly designed chamber. When heating up the foamed ceramic, the Pd/SnO22 sensor shows a significant sensitivity to acetone. The sensor signal decreases on methane, acetaldehyde and carbon monoxide. Furthermore, a temperature dependency to the ambient gas concentration and an adsorption on the ceramic filter is observed. Due to the fact that the heated filter is independent of the sensor heater, it is possible to operate the sensor at its ideal operating temperature for the target gases along with the additional opportunity of indirect gas determinations. © 2012 The Authors.

Due to increasing interest in indoor air quality (IAQ) monitoring for demand controlled ventilation (DCV) aiming at improved perceived air quality, health, energy and cost saving, the objective of this study has been the development of a sensor module based on a single microelectromechanical-system (MEMS) metal oxide semiconductor (MOS) gas sensor for IAQ monitoring as close as possible to the human sensory impression in indoor environments. Based on the results of a statistical evaluation on human induced volatile organic compounds (VOCs) in the ambient air of indoor environments correlating with human presence and perceived air quality, the performance of differently doped SnO2 thick film gas sensor materials has been investigated in laboratory and by means of field tests in order to find the most promising sensor material for IAQ monitoring based on the detection of changes of human induced VOCs in indoor air. Implementation of an empirical evaluation algorithm reversing proportionality of anthropogenic CO2 production and other bio-effluent generation allows prediction of CO2 equivalent units. Analytical instrumentation and reference sensors served to evaluate the effectiveness of the developed sensor module in real-life. © 2010 Elsevier Ltd.

Highly miniaturized low-power drop-coated metal-oxide gas sensors on polyimide foil are presented. Drop-coating of SnO 2-based material was successfully achieved on transducers as small as 15 μm on polyimide, a substrate compatible with the printed electronics industry. The sensors showed a very good chemoresistive response when exposed to CO and NO 2. The power consumptions of the sensors ranged from a minimum of 7.7 mW for the smallest hotplate at 200 °C to a maximum of 28.4 mW for the largest device at 250 °C in continuous mode of operation. In a pulsed mode, their consumption was reduced to the sub-milliwatt range for the 15 μm wide heaters while keeping a good chemoresistive response, widening their use to low-power applications, such as for wireless systems. The sensors were interfaced to a custom-made electronic circuitry with a readout based on time-to-digital conversion to minimize the amount of electronic components and reduce the power consumption. The power consumption of the 15 μm wide sensor was 680 μW in pulsed mode, while the sensor system exhibited a total power consumption of 1.9 mW. © 2011 Elsevier B.V. All rights reserved.

Energy-efficient ventilation strategies relating to good indoor air quality (IAQ) are a major task for building performance according to the requirements set by the energy performance of buildings directive (EPBD) in 2010. Applying demand-controlled ventilation (DCV) in buildings, using sensors for IAQ control that enables variable airflow rates adapted to the actual indoor load conditions is one possibility to fulfill the requirements of adequate IAQ while reducing the energy consumption at the same time. CO2 concentrations above outdoors are generally used as an indicator for occupancy generated indoor air pollution and corresponding ventilation rates. The objective of this study is focused on a micromachined metal oxide semiconductor gas sensor module developed for IAQ control, based on volatile organic compound (VOC) detection. The sensor output was correlated with measured CO2 concentrations and quantified VOCs in 15 field scenarios. Energy demand and IAQ, applying the sensor module for DCV in an office, were compared to natural and time-scheduled ventilation in the office. The study accentuates the need for DCV and proves the functionality of the sensor module for IAQ control at adequate comfort levels. Compared to time-scheduled ventilation, 15% heating energy and 70% power consumption were saved with DCV. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
