Within the Flexnode Plus project the long-term degradation characteristics of a proton exchange membrane (PEM) electrolyzer (5.5 kW, AC, 1 Nm3/h H2) and fuel cell (1.0 kW, DC, 0.9 Nm3/h) was experimentally tested. The electrolyzer unit was operated at various loads and pressures for approximately 750 hours in total, while the fuel cell was operated at a constant load of 1 Ω resistance for approximately 1120 hours in total. The efficiency of the hydrogen production in the electrolyzer and the electricity production in the fuel cell was expressed using the hourly average system efficiency and average cell efficiency. Inorder to predict the state of health and remaining lifetime of the electrolyzer cell and fuel cell, the decay of the cell voltage over time was monitored and the direct mapping from aging data method was used.The electrolyzer cell showed a stable cell voltage and cell efficiency in the studied time period, with an average cell voltage decay rate of 0.5 μV/h. The average cell voltage of the fuel cell dropped with a rate of 2 μV/h during the studied time period.
Ever since the recognition of the causality between earthquakes in the Region Groningen (The Netherlands), gas production and the ensuing damage to houses and buildings in that area, government faces big challenges in policy-making. On the one hand liability for damages must result in fast and effective repair of houses and buildings and in safety safeguards for the infrastructure. On the other hand public trust in governmental institutions in the Earthquake area Groningen has to be restored.As a result of the advice of the Commission ‘Sustainable Future North East Groningen’ a comprehensive package of measures called ‘Trust in restoration, Restoration of trust’ (‘Vertrouwen op herstel, Herstel van vertrouwen’) was announced in which public-private partnerships were introduced for the purpose and in favor of the economic perspective of the region, including the establishment of local initiatives on sustainable energy, damage repair and guaranteeing a confidential approach by the government.Multiple actors are involved in the execution of this package of measures, since the competence of decision-making lies at State, regional and local level. Together with the emergence of public-private partnerships this all results in a very complex case of multi-level governance and policy-making.The central research question this article addresses is whether public-private partnerships contribute in a legal and effective manner to policy-making following the package of measures ‘Trust in restoration, Restoration of trust’ in the Energy Port Region Groningen.
Het samen met het MKB werken aan de ontwikkeling van de waterstofketen in Noord-Nederland (en verder) door middel van testen, demonstreren, leren en het aanbieden van een open innovatie.Het verzamelen van kennis, bouwen aan een platform en creëren van een netwerk voor en samen met MKB Noord-Nederland op het gebied van groene waterstof.De Groene Waterstofbooster is gericht op het neerzetten van een open innovatie op EnTranCe, dé energieproeftuin van Groningen. De doelgroep van de GWB is het MKB in Noord-Nederland (Groningen, Friesland & Drenthe). GasUnie en GasTerra nemen als financiële partners deel aan het project. Het programma wordt ondersteund door SNN.
