This report describes the creation and use of a database for energy storage technologies which was developed in conjunction with Netbeheer Nederland and the Hanze University of Applied Sciences. This database can be used to make comparisons between a selection of storage technologies and will provide a method for ranking energy storage technology suitability based on the desired application requirements. In addition, this document describes the creation of the energy storage label which contains detailed characteristics for specific storage systems. The layout of the storage labels enables the analysis of different storage technologies in a comprehensive, understandable and comparative manner. A sampling of storage technology labels are stored in an excel spreadsheet and are also compiled in Appendix I of this report; the storage technologies represented here were found to be well suited to enable flexibility in energy supply and to potentially provide support for renewable energy integration [37] [36]. The data in the labels is presented on a series of graphs to allow comparisons of the technologies. Finally, the use and limitations of energy storage technologies are discussed. The results of this research can be used to support the Dutch enewable Energy Transition by providing important information regarding energy storage in both technically detailed and general terms. This information can be useful for energy market parties in order to analyze the role of storage in future energy scenarios and to develop appropriate strategies to ensure energy supply.

The development of the World Wide Web, the emergence of social media and Big Data have led to a rising amount of data. Information and Communication Technologies (ICTs) affect the environment in various ways. Their energyconsumption is growing exponentially, with and without the use of ‘green’ energy. Increasing environmental awareness has led to discussions on sustainable development. The data deluge makes it not only necessary to pay attention to the hard- and software dimensions of ICTs but also to the ‘value’ of the data stored. In this paper, we study the possibility to methodically reduce the amount of stored data and records in organizations based on the ‘value’ of information, using the Green Archiving Model we have developed. Reducing the amount of data and records in organizations helps in allowing organizations to fight the data deluge and to realize the objectives of both Digital Archiving and Green IT. At the same time, methodically deleting data and records should reduce the consumption of electricity for data storage. As a consequence, the organizational cost for electricity use should be reduced. Our research showed that the model can be used to reduce [1] the amount of data (45 percent, using Archival Retention Levels and Retention Schedules) and [2] the electricity consumption for data storage (resulting in a cost reduction of 35 percent). Our research indicates that the Green Archiving Model is a viable model to reduce the amount of stored data and records and to curb electricity use for storage in organizations. This paper is the result of the first stage of a research project that is aimed at developing low power ICTs that will automatically appraise, select, preserve or permanently delete data based on their ‘value’. Such an ICT will automatically reduce storage capacity and reduce electricity consumption used for data storage. At the same time, data disposal will reduce overload caused by storing the same data in different formats, it will lower costs and it reduces the potential forliability.

Het project van Aeres Hogeschool Dronten heeft als doel om via het delen en analyseren van telersdata binnen een groep van dertien telers te komen tot nieuwe inzichten, betere bedrijfsvoering en efficiëntere ketens, gericht op economische en ecologische duurzaamheid. Hiervoor wordt een data-infrastructuur gerealiseerd waarmee telers gefaciliteerd worden in het verzamelen, delen en analyseren van data en toegang krijgen tot complexere analyse technieken. Het project beoogt een groep telers op te leiden om de infrastructuur en tools te gebruiken en gezamenlijk data te delen en te analyseren om de teelt te verbeteren. Aan het einde van het project worden concrete verbeteringen verwacht op het gebied van input en opbrengst in de aardappelteelt.Het project richtte zich op het onderzoeken van hoe data van agrarische ondernemers in Flevoland gebruikt en gedeeld kan worden om economische en ecologische verbeteringen te bereiken. De landbouwsector verzamelt steeds meer gegevens over variabelen die de groei en bewaring van gewassen beïnvloeden, waarmee de benadering van landbouw verduurzaamd kan worden. Echter, het gebruik van data staat nog in de kinderschoenen en beslissingen worden vaak genomen op basis van advisering van externe commerciële partijen. Het delen van data is ook nog gevoelige materie. Het project wil deze drempels verlagen door telers meer data onderling te laten uitwisselen en met partners in de keten.De data-infrastructuur wordt gerealiseerd voor een groep van 15-20 telers die bereid zijn teelt- en/of bewaarsturing te doen op basis van beschikbare object-specifieke en actuele data. De data kunnen met elkaar gedeeld worden en zo kunnen de bedrijven verbeterd worden. De telers krijgen via de infrastructuur toegang tot complexere analyse technieken. Het project is opgedeeld in drie groepen op basis van locatie in de provincie: een groep telers rond een pilot bedrijf in Dronten, een groep rond een pilot bedrijf in Swifterbant en een groep in de NOP.De drie pilot bedrijven hebben aan het begin van het project een inventarisatie gedaan op basis van een door Aeres opgestelde vragenlijst om inzicht te krijgen in de minimale beschikbare data voor deelname aan het project. De meeste gevraagde data zijn reeds beschikbaar, behalve bij het pilot bedrijf in de NOP. De ontbrekende data kunnen worden opgevraagd bij lokale weerstations of in het project door projectpartners worden gerealiseerd.In de agrarische sector komt het vaak voor dat er ontbrekende data zijn over de factoren die bijdragen aan mislukkingen in de precisielandbouw. Dit komt doordat er vaak wordt gedacht in termen van wat wel werkt, in plaats van wat niet werkt. Een manier om dit tegen te gaan is door bewust te zijn van de ontbrekende data en deze proactief op te zoeken. Dit kan bijvoorbeeld door onderzoek te doen naar de milieu-impact van landbouw.Door dit project is beter inzicht verkregen in de effectiviteit van inputs alsmede met betrekking tot de impact op de omgeving. De volgende verbeteringen zijn gerealiseerd:• Beter inzicht in timing van teelthandelingen waardoor de bodem wordt ontzien.• Beter inzicht in effecten van teeltrotaties waardoor gekozen kan worden voor rotaties met minder impact en toch goede financiële resultaten behaald worden.• Door vergelijking kan er effectiever omgegaan worden met inputs zoals mest en gewasbeschermingsmiddelen waardoor naast minder gebruik ook minder af- en uitspoeling zal plaatsvinden.• Door effectiever gebruik van inputs zal per kg geproduceerde aardappelen minder oppervlakte, energie en chemie nodig zijn.Trefwoorden: digitalisering boerenbedrijf, data, pop3, databoeren, precisielandbouw RVO zaaknummer: 17717000042

Abstract Despite the numerous business benefits of data science, the number of data science models in production is limited. Data science model deployment presents many challenges and many organisations have little model deployment knowledge. This research studied five model deployments in a Dutch government organisation. The study revealed that as a result of model deployment a data science subprocess is added into the target business process, the model itself can be adapted, model maintenance is incorporated in the model development process and a feedback loop is established between the target business process and the model development process. These model deployment effects and the related deployment challenges are different in strategic and operational target business processes. Based on these findings, guidelines are formulated which can form a basis for future principles how to successfully deploy data science models. Organisations can use these guidelines as suggestions to solve their own model deployment challenges.

Hybrid Energy Storage System (HESS) have the potential to offer better flexibility to a grid than any single energy storage solution. However, sizing a HESS is challenging, as the required capacity, power and ramp rates for a given application are difficult to derive. This paper proposes a method for splitting a given load profile into several storage technology independent sub-profiles, such that each of the sub-profiles leads to its own requirements. This method can be used to gain preliminary insight into HESS requirements before a choice is made for specific storage technologies. To test the method, a household case is investigated using the derived methodology, and storage requirements are found, which can then be used to derive concrete storage technologies for the HESS of the household. Adding a HESS to the household case reduces the maximum import power from the connected grid by approximately 7000 W and the maximum exported power to the connected grid by approximately 1000 W. It is concluded that the method is particularly suitable for data sets with a high granularity and many data points.

In the Dutch construction industry, the demand for advanced information storage and sharing is growing due to the complexity of construction projects. Limitations of traditional methods include lack of transparency and inefficient communication. Blockchain offers a promising solution by enabling decentralized storage and immutable recording of data increasing transparency and efficiency in the construction supply chain. Combining a Common Data Environment with the InterPlanetary File System – decentralized file storage and exchange, and a powerful tool for secure, efficient and reliable data management in construction – can emerge to improve cooperation between parties increasing effectiveness of projects.

The possibilities of balancing gas supply and demand with a green gas supply chain were analyzed. The considered supply chain is based on co-digestion of cow manure and maize, the produced biogas is upgraded to (Dutch) natural gas standards. The applicability of modeling yearly gas demand data in a geographical region by Fourier analysis was investigated. For a sine shape gas demand, three scenarios were further investigated: varying biogas production in time, adding gas storage to a supply chain, and adding a second digester to the supply chain which is assumed to be switched off during the summer months. A regional gas demand modeled by a sine function is reasonable for household type of users as well as for business areas, or a mixture of those. Of the considered scenarios, gas storage is by far the most expensive. When gas demand has to be met by a green gas supply chain, flexible biogas production is an interesting option. Further research in this direction might open interesting pathways to sustainable gas supply chains.

Abstract The Government of the Netherlands wants to be energy neutral by 2050 (Rijksoverheid, sd). A transition towards non-fossil energy sources also affects transport, which is one of the industries significantly contributing to CO2 emission (Centraal Bureau Statistiek, 2019). Road authorities at municipalities and provinces want a shift from fossil fuel-consuming to zero-emission transport choices by their inhabitants. For this the Province of Utrecht has data available. However, they struggle how to deploy data to positively influence inhabitants' mobility behavior. A problem analysis scoped the research and a survey revealed the gap between the province's current data-item approach that is infrastructure oriented and the required approach that adopts traveler’s personas to successfully stimulate cycling. For this more precisely defined captured data is needed and the focus should shift from already motivated cyclists to non-cyclers.
