To enable the use of renewable energy throughout the system, the Dutch government aims to rely strongly on hydrogen gas as a green energy carrier. This thesis is dedicated to assessing the feasibility of meeting the future Dutch hydrogen demand with locally produced green hydrogen through offshore wind. The aim was realized by modelling the Dutch hydrogen demand in 2050 based on government plans and comparing this with the amount of green hydrogen the Netherlands can produce through offshore wind. Methods used include extensive literature reviews, energy system modelling, scenario analysis, and calculations. The results show that between 1,28 and 2,04 EJ of wind energy is necessary to meet the regular electricity demand and the electricity demand for hydrogen production through electrolysis. This needs to be compared to an offshore wind energy potential in the Dutch North Sea that ranges between 0,67 and 1,79 EJ. An analysis of the results shows that the offshore wind demand could be met, but it is more likely that the offshore wind energy potential is insufficient to meet the demand. The government envisions five applications for hydrogen, namely to be used as feedstock for the process industry, to generate high temperature heat, as energy storage for renewables (balancing the grid), as a transport fuel, and in the built environment. The results indicate that the demand of these five applications is unlikely to be met completely with offshore wind green hydrogen. However, the large majority of the hydrogen demand is dedicated to be used as a feedstock for the process industry. If this feedstock were to be from another source, meeting the demand of the remaining hydrogen applications with offshore wind is more realistic. Consequently, a main take-away is that the creation of a wind and solar based electricity grid with green hydrogen as a balancing agent is feasible. The results of this research gave rise to several recommendations. Firstly, renewable energy generation should be maximized using the full scope of different available techniques (not only focusing on offshore wind). Second, different decarbonization pathways other than offshore wind green hydrogen should be explored to account for process industry feedstocks. Third, the government should work closely together with other North Sea-bordering countries in order to make the best use of the available space. Fourth and final, efforts should be steered towards maximizing the wind energy potential of the Dutch North Sea, which is ideally suited for wind energy generation and should therefore be used in the best way possible.

The diploma thesis deals with the social movement Fridays for Future and its activity in the Federal Republic of Germany. The study describes frames which are used by the movement to communicate with public and to mobilize its supporters. In the analysis the thesis is based on the framing theory, which was in more detail elaborated by David A. Snow and Robert D. Benford. Specifically, the thesis deals with the analyses of the frames that occurred in the selected speeches delivered by the activists of the movement Fridays for Future. To be more precise, it is the diagnostic, prognostic, and motivational framing. At the beginning of the movement there was the Swedish activist Greta Thunberg who came up with the idea of school strikes for climate. The movement resonated strongly in the German society and it managed to mobilize an extraordinary amount of people in comparison to other states. The central aim of this thesis is to characterize the movement Fridays for Future in Germany. The thesis concentrates on the official goals that the movement tries to push through at the level of the German politics. Furthermore, it focuses on the collective identity and composition of the demonstration participants, primarily it dedicates to social and demographic features of the demonstrators. Besides, the thesis...

Introduction The report includes a study on how environmental certification tools are used to reduce the climate impact in the construction sector. In 2020, the Swedish construction sector accounted for approximately 21 percent of Sweden´s greenhouse gas emissions. Sweden´s climate goals consist of achieving net zero by the year 2045. The aim of the study was to investigate the view of environmental certification tools. Does the environmental certification motivate to build more sustainably. The study investigated what the work with environmental certifications looks like today. Investigations into environmentally certified building projects are sufficient measures for the industry to reduce emissions and whether the environmental certification process can be simplified. Method The method used was survey and the data collection technique in this study was research interviews. The respondents were people that are working within the construction sector. The interviews were semi structured with set questions and open answers. Results The result from the collected data showed a broad view of environmental certification. The major obstacles described are cost and time for an environmental certification. The use of environmental certification to achieve the climate goals can be used as a tool but is not sufficient. To reach the climate goals and build more sustainable, changes need to come in the form off laws and regulations. Analysis  The environmental certifications contribute to more sustainable construction by working with them as a tool. To be able to certify the environment, it is important that the customer wants to be certified. The environmental certifications need to develop at the same pace as the outside world to be relevant to use. The flexibility to design a building needs to be there to motivate the workers to use the environmental certifications. A motivational factor can be beneficial for workers to want to work with the environmental certifications. To build more sustainably, stricter laws and regulations are required. Discussion  Environmental certifications are used more and more, but do not motivate everyone in the construction sector to build more sustainably. There are several challenges that need to be addressed to simplify the environmental certification process and to build more sustainably and reach the climate goals.
