Innovative large-scale energy storagetechnologies and Power-to-Gas concepts after optimisation

New technologies or approaches are being widely developed and proposed to be deployed in real energy systems to improve desired objectives; however, supporting decision making processes to select best solutions in terms of performance and efficiently following cost-benefit analysis require some sort of scientific evidence based tools. These tools should be reliable, robust, and capable of demonstrating the behaviour and impact of newly developed devices or algorithms in different pre- defined scenarios. Therefore, new approaches and technologies need to be tested and verified using a safe laboratory test environment.This report is about the development and realisation of some major tools and reliable methods to calculate risks and opportunities for integrating of new energy resources into the European electricity grid. Hanze University Groningen and Politecnico di Torino worked together within the STORE&GO project sharing laboratories, knowledge, hardware facilities and researchers for the realisation of the characterisation and mathematical modelling of renewable resources. Needed to realize a stable and reliable environment for remote physical hardware in the loop simulations.For this realisation we started with the local characterisation of a PV-Field and a PEM electrolyser at Entrance Groningen by logging and measuring the electric behaviour and specific device parameters to integrate and convert these into working mathematical models of a PV-Field and electrolyser prosumer. After testing and evaluating these models by comparing the results with the real-time measurements, these test and modelling is also realised from the remote laboratory in Torino. To achieve dynamical physical hardware we also realised dynamic mathematical model(s) with real-time functionality to interact directly with the remote electrolyser. To connect both the laboratories with full duplex communication functionalities between physical hardware and models we have also realized a network which is able to share network resources on both local and remote sites.

Innovative large-scale energy storage technologies and Power-to-Gas concepts after optimisation

The project STORE&GO aims to investigate all the aspects regarding the integration of large-scale Power-to-Gas (PtG) at European level, by exploiting it as means for long term storage. One of the aspects that should be properly addressed is the beneficial impact that the integration of PtG plants may have on the electricity system.In the project framework, WP6 devoted its activities to investigate different aspects of the integration of PtG in the electricity grid, with the previous delivered reports.This deliverable focused in particular on how integrate the information about the facilities replicating the real world condition into a simulation environment. For doing this, the concept of remote Physical Hardware-in-the-Loop (PHIL) has been used and exploit.Remote simulation with physical hardware appears to be an effective means for investigating new technologies for energy transition, with the purpose of solving the issues related to the introduction of new Renewable Energy Sources (RES) into the electricity system. These solutions are making the overall energy systems to be investigated much more complex than the traditional ones, introducingnew challenges to the research. In fact:• the newly integrated technologies deal with different energy vectors and  sectors, thus• requiring interoperability and multidisciplinary analysis;• the systems to be implemented often are large-scale energy systems leading to enormously complicated simulation models;• the facilities for carrying out the experiments require huge investments as well as suitable areas where to be properly installed.This may lead to the fact that a single laboratory with limited expertise, hardware/software facilities and available data has not the ability to secure satisfactory outcomes. The solution is the share of existing research infrastructures, by virtually joining different distant laboratories or facilities.This results in improvement of simulation capabilities for large-scale systems by decoupling into subsystems to be run on distant targets avoidance of replication of already existing facilities by exploiting remote hardware in the loop concept for testing of remote devices.Also confidential information of one lab, whose sharing may be either not allowed or requiring long administrative authorization procedures, can be kept confidential by simulating models locally and exchanging with the partners only proper data and simulation results through the co-simulation medium.Thanks to the realized method it is possible to real time analyse renewable devices at remotepower plants and place them in the loop of a local network simulation.The results reported show that the architecture developed is strong enough for being applied also atnew renewable power plants. This opens the possibility to use the data for research purposed, butalso to act in remote on the infrastructure in case of particular test (for example the acceptance test).

Feeling the News?

Immersive journalism (IJ) is often assumed to be inherently emotion-inducing. Through using inclusive technology, interaction possibilities and immersive narratives, the audience should ideally experience what feels like to be in a certain situation. However, for the most part we do not know to which extent and in what form IJ influences the experience of emotions. We wanted to investigate, whether, and if so, which characteristics of IJ are related to the experience of emotions, and which role the personality trait empathy tendency plays in this respect. This is important, as the evaluation of IJ often relies on the emotion-inducing assumption thereof. Four different experiments comparing one immersive journalistic characteristic (level of inclusion, interaction possibilities, immersive narratives) to the respective non-immersive counterpart were conducted. Results indicate that while the level of inclusion and interaction possibility increase the intensity of the experience, the immersive narrative influences the valence dimension of emotions. Additionally, empathy tendency is found to be a relevant moderator for these effects. Conclusions are threefold. First, the narrative form of IJ is key; second, the analysis of IJ needs to go beyond the level of inclusion; third, including emotions when assessing IJ is fundamental to understand its impact.

Performing affirmation

This text has become a performance of (affirmative) entrepreneurship. This is done by a set of writing (and methodological) techniques: autoethnography, the triptych of mimesis, poiesis, kinesis and a life journey that forms the base of the chapter. As such, this text challenges some well-known shortcomings of entrepreneurship research such as being enacted by a distant observer/writer, decontextualized accounts of entrepreneurship and disregard of creativity and playfulness. The main contribution of the chapter is methodological, in its broadest sense (Steyaert, 2011): I propose autoethnography as “more than method” for engaging with processes of (affirmative) Entrepreneuring that speak to the increased attention for narrativity and playfulness in entrepreneurship (see for example Hjorth, 2017: Hjorth and Steyaert, 2004: Gartner, 2007; Johannisson, 2011). The autoethnographic story offers an engaging and relevant account of the practice of entrepreneurship and provides rich emic insight into the socio-materiality of lived experience. It also highlights the temporality of entrepreneurship – both in terms of chronos (continuous flow of time) and Kairos (taking advantage of the “right moment”) (Johannisson, 2011). And as I continue performing affirmations, I am curious how you are Entrepreneuring your life – tell me. This is a draft chapter/article.
