Due to the exhaustion and increased pressure regarding the environmental and political aspects of fossil fuels, the industrial focus has switched towards renewable energy resources. Lignocellulosic biowaste can come from several sources, such as industrial waste, agricultural waste, forestry waste, and bioenergy crops and processed into bioethanol via a biochemical pathway. Although much research has been done on the ethanol production from lignocellulosic biomass, the economic viability of a bioethanol plant in the Northern Netherlands is yet unknown, and therefore, examined. In this thesis, the feasibility study of a bioethanol plant treating sugar beet pulp, cow manure, and grass straw is conducted using the simulation software SuperPro Designer. Results show that it is not economically viable to treat the tested lignocellulosic biomass for the production of bioethanol, since all three original cases result in a negative net present value (NPV). An alternative would be to exclude the pretreatment step from the process. Although this results in a lower production of bioethanol per year, the plant treating sugar beet pulp (SBP) and grass straw (GS) becomes economically viable since the costs have significantly decreased.
Workpackage 8.1 of the IANOS project is dedicated to developing a community engagement strategy that can be applied in the use cases on the lighthouse islands (Ameland and Terceira) and the fellow islands (Lampedusa, Nisyros and Bora Bora). This report is the deliverable of WP8.1.Within this report an approach to designing a community engagement strategy is formulated that is rooted in scientific research and enriched by best practices from the light house islands and fellow islands.The report describes a general approach to designing a community engagement strategy, that consists of three parts. The first part is dedicated to assessing the situation and project that the community engagement strategy is dedicated to. It describes several factors that are rooted in literature on community engagement and psychological theories. Thesefactors should be assessed in order to be able to design an effective community engagement strategy. The results of this assessment will be used in the second part of the general approach, which describes a method for designing a community engagement strategy. This method is rooted in community engagement literature and draws heavily on some earlier EU projects. The method describes about ten items that together constitutethe strategy and that encompass all relevant issues that need to be addressed in designing community engagement. Finally, the third part of the general approach, describes the way the method and the assessment can be applied in a methodic and robust way. Although the general method is described as a theoretically based approach, it is substantiated not only by theoretical studies, but also by many reports on practical application of various community engagement efforts. In addition to that, all participantsfrom the islands have identified some best practices on community engagement from their own region and/or experience. These best practices are analysed according to the method of meta-analysis. The information from this meta-analysis is used to check the suitability of the general approach and leads to emphasizing those aspects of the approach that are identified as more important within the best practices.

This report focuses on the feasibility of the power-to-ammonia concept. Power-to-ammonia uses produced excess renewable electricity to electrolyze water, and then to react the obtained hydrogen with nitrogen, which is obtained through air separation, to produce ammonia. This process may be used as a “balancing load” to consume excess electricity on the grid and maintain grid stability. The product, ammonia, plays the role of a chemical storage option for excess renewable energy. This excess energy in the form of ammonia can be stored for long periods of time using mature technologies and an existing global infrastructure, and can further be used either as a fuel or a chemical commodity. Ammonia has a higher energy density than hydrogen; it is easier to store and transport than hydrogen, and it is much easier to liquefy than methane, and offers an energy chain with low carbon emissions.The objective of this study is to analyze technical, institutional and economic aspects of power-to-ammonia and the usage of ammonia as a flexible energy carrier.
