The Validation and Evaluation sub-project of the eCoMove project groups a number of complementary activities including the core tasks to validate the functionality of the eCoMove system and applications, and to evaluate if the aimed reduction of 20% overall energy consumption can be achieved. Besides technical requirements a validation process also has to consider non-technical requirements of potential users of the eCoMove system which were in the focus of research for this deliverable.

Solar thermal hydrogen production with sulphur based thermochemical cycles can reach significantly higher efficiency than conventional water electrolysis. For these cycles decomposition of sulphuric acid is a key step allowing to couple concentrated solar radiation into the process. DLR developed a two-chamber test reactor to technically realise and experimentally analyse this reaction in the solar furnace in Cologne. Moreover, a model of the second reaction chamber for decomposition of SO3 was implemented and validated by experimental data.

Cooperative ITS for road traffic offer potentials regarding road safety and traffic efficiency that go significantly beyond what can be achieved with isolated vehicle and infrastructure systems. However, besides functional and technical aspects there are legal and institutional, financial, political and culture barriers that need to be addressed and must be overcome in order to successfully deploy cooperative services on a broad level throughout Europe. This paper contains an analysis of identified barriers and their possible solutions on the basis of the eCoMove project and several research projects that deal with to C-ITS implementation.

Der Energieträger Wasserstoff wird im Verkehrssektor in den kommenden Jahren zunehmend an Bedeutung gewinnen. Eine mögliche Alternative zur zentralen H2-Erzeugung aus Erdgas ist die dezentrale Bereitstellung von Wasserstoff durch Reformierung von Flüssigbrennstoffen. Im Rahmen des EU-Projektes NEMESIS2+ (www.nemesis-project.eu) wird ein Wasserstoffgenerator (50 Nm3/h) auf Basis von Diesel und Biodiesel entwickelt. Am DLR Stuttgart werden im Rahmen des Projektes grundlegende experimentelle Untersuchungen zur Dampfreformierung von Diesel und Biodiesel durchgeführt. Diese werden ergänzt durch eine modelltechnische Abbildung des Gesamtsystems mit Aspen Plus ®.

We present a low maintenance system to record the solar irradiance in remote places or difficult access, with a ventilated thermal pyranometer, a rotating shadowband and a structure with movable supports. It is designed to work autonomously with a cleaning device that cleans the spherical glass of the sensor by blowing with compressed air and brushing; a rotating shadowband and a protection arm; a power supply comprising a battery and a solar panel; a control device with an electronic card coupled with the guiding means to establish the position of the shading band with respect to the sensor and to establish measurement intervals in sun and shadow conditions, according to geographical location, date, time of day and response time of the pyranometer. A data acquisition device records the measurements made and these are stored in Memory.
