The move towards addressing two pertinent energy challenges that is access to electricity and climate change has seen the transition towards sustainable forms of energy including Ocean Based Renewable Energy (OBRE). However, much work remains to be done in understanding the critical success factors that could enable such potential transition, especially in the area of OBRE electricity generation. This research addresses this concern by drawing on transition theory and frameworks to critically evaluate the prospects towards OBRE development in Nigeria. The rationale for the study stems from issues around the inadequate supply of electricity, which has become a profound concern and, where its absence is mostly observed in rural and remote areas including coastal communities. Based on an interpretative philosophical stance, the study adopted a qualitative approach for conducting the research. In-depth semi-structured interviews were used to collect data from twenty-seven research participants. The research findings revealed that there is scope for transitioning towards OBRE electricity generation. However, this potential may be hindered by key features of the incumbent socio-technical regime: inconsistency of statements in formal policy documents; unclear institutional arrangements to foster renewable energy development; and lack of regulatory and market support mechanisms, which keep renewable energy development at the margins. Nevertheless, the study found certain perceived critical success factors that when considered could aid in facilitating OBRE development in Nigeria. These included, in particular, meaningful stakeholder engagement that aimed to harmonise the diverse interests of key actors’ and the role of adequate political governance to facilitate OBRE design and implementation. The research concludes by developing a conceptual intervention model called the OBRE Transition Model. This model argues that through more meaningful engagement with pertinent stakeholders’ and stronger political commitment, the prospect for a transition towards OBRE development in Nigeria could be accomplished. This thesis is the first of its kind to study the prospects for a transition towards OBRE innovation in West Africa. Additionally, the model that has been developed is now going to be corroborated in an OBRE project in Nigeria, thus, forming the evidence on the model’s potential applicability for future study.

How long would modern society cope with a power outage, what would happen to vital systems that we today take for granted in modern society. The Nordic electricity grid is facing a major shift where electricity production from non-renewable sources are to be replaced increasingly by renewable sources. By increasing the penetration of wind and solar power the electric power system might be exposed to disturbances due to decreasing inertia as a result of the electricity transition. Currently the electric power system has different reserves to use to maintain frequency stability but there are other reserves that could help further in the fight for the balance between electricity production and consumption. This project examines whether the new reserve service, fast frequency reserve (FFR), can help the existing frequency containment reserve for disturbed (FCR-D) operation. Therefore, two experiments were conducted using the simulation tool ARISTO, addressing relevant issues involving frequency stability. Motivation for the hypothesis was to investigate if FFR could reduce the frequency transients and improve frequency variations by developing various setups and cases when inertia was retained and when the system inertia was reduced at different stages. The results of the experiments showed that the global minimum frequency, nadir, had increased for all test cases compared to the reference case when using FFR, this proved that the FFR in fact help reducing frequency transients. The results showed furthermore that when the FFR had a duration time of 30 seconds compared to only 5 seconds, the frequency variations could be improved for certain setups for experiment 2.

Energy transition (ET) to renewable energy sources (RES) has been identified as a crucial action needed in combating climate change. These societal transitions have barriers which are hard to quantify and thus hard to incorporate in energy modelling scenarios. Full-scale island societies offer a unique position in observing societal changes that accompany ET technology. Islands also offer an understanding of how holistic sustainable development agendas and clear leadership can help facilitate an ET at a local level by identifying local barriers and bottlenecks. The autonomous territory, the Åland Islands, was chosen as a case study to investigate the role municipal governance leadership has on ET. 15 municipal actors in three different governing roles, from five different municipalities, were interviewed in individual semi-structured interviews. The results show that economic barriers were not perceived as a hindrance if local ET planning and budgeting is done thoroughly and followed up. The main barriers identified are social and include gender and age imbalances, lack of transparent communication, segregation of stakeholders and lack of cooperation between municipalities. The interviewees all saw benefits with undertaking an ET, both economically and socially, but seem unsure of who should take on this responsibility. There is lack of local adoption and holistic planning for ET, even if the actors in the municipalities express their willingness to undertake one – but with no clear regional ET agenda or leader to shoulder the task, it is unlikely that Åland will achieve the energy goals set to be reached 2030. / <p>Presentation was done online due to COVID-19</p> / Smart Energy Åland

The current state of energy and climate transition presents several challenges that are currently not optimally addressed by planning and design practices. Indeed, cities play a central role in this transition, as they are within the main causes of climate change as well as extremely vulnerable to its effects, such as extreme events. In this context, the disciplines of urban planning and design are a great resource for promoting mitigation and adaptation strategies. However, there is a gap between scientific research on the issues and the actual implementation of the resources, mainly due to the inability of planning tools to address these needs, the difficulty of transforming the existing built environment and the engagement of citizens in these processes. These issues can be translated into four knowledge gaps that can be addressed by the disciplines of planning and design: lack of explicit considerations of resilient pathways, lack of innovative implementation tools, local resistance towards landscape transformations, silo thinking. The goal of the thesis is to identify, develop and evaluate climate-sensitive planning and design strategies, considering the environmental criteria, the urban areas and the people who live in them. The research is practice-oriented and gives directions on how to apply scientific knowledge through practices for a responsive and landscape-inclusive climate-energy transition. Specifically, it aims to combine several challenges and promote holistic procedures balancing adaptation and mitigation strategies as well as to include the concept of landscape in the transition. The proposed methodologies are evidence-based, performance-based and landscape-inclusive, connecting different scales of intervention, disciplinary tools, and practices of planning and design. In other words, the thesis promotes urban regeneration for climate and energy transition through an integrated approach between landscape, city, and buildings. This integrated approach addresses the following dimensions of urban challenges: social, environmental, economic, and health.

Ausgehend von der Feststellung, dass einerseits Innovationsprozesse in ländlichen Räumen wenig erforscht sind und andererseits das Wissen um die Innovationsfähigkeit ländlicher Akteure dringend erforderlich ist, um eine nachhaltige Transformation zu erreichen, beschäftigt sich diese Dissertation mit der Frage, wie soziale Innovationsprozesse in ländlichen Räumen funktionieren und gefördert werden können. Es wurden drei Studien erstellt, die sich der Beantwortung dieser Frage aus unterschiedlichen Perspektiven nähern. Beginnend mit dem Thema der nachhaltigen Zertifizierung von Ölpalmen-Kleinbauern in Indonesien, der Frage der Erhaltung und Schaffung ländlicher Infrastruktur in Deutschland und dem Thema der Energiewende und ihrer Förderung. Im Mittelpunkt aller Studien steht die Untersuchung kollektiven Handelns von mitgliederbasierten Organisationen, die als Sozialunternehmen im ländlichen Raum gegründet und betrieben werden. Zusammenfassend lässt sich feststellen, dass die Rolle von mitgliedschaftsbasierten Organisationen in ländlichen Gebieten die Untersuchung von sozialen Innovationsprozessen ermöglicht. Es konnten wichtige Merkmale und Prozesse sozialer Innovationsprozesse identifiziert werden, die nicht nur für die Förderung von mitgliederbasierten Organisationen, sondern auch für die Untersuchung nachhaltiger Transformationspfade vielversprechend sind. Die Dissertation schließt mit einer kritischen Diskussion über die Grenzen der Doktorarbeit, dem Bezug zu aktuellen wissenschaftlichen Debatten, einigen Governance Empfehlungen und einer Positionierung der Forscherin in ihrem Forschungsfeld. / Based on the observation that, on the one hand, innovation processes in rural areas have been little researched and, on the other hand, knowledge about the capacity for change of rural actors urgently needs to be taken into account to achieve sustainable transformation, this dissertation deals with the question of how social innovation processes in rural areas function and can be promoted. Three studies were conducted that approach the answer to this question from different perspectives. Starting with the issue of sustainable certification of oil palm smallholders in Indonesia, the issue of maintaining and establishing rural infrastructure in Germany, and the topic of the renewable energy transition and its promotion. At the heart of all studies is an examination of collective action by membership-based organizations established and operated as social enterprises in rural areas. In conclusion, the role of membership-based organisations in rural areas enables the study of social innovation processes. Important characteristics and processes of social innovation governance could be identified, which are promising not only for promoting membership-based organisations but also for studying sustainable transformation pathways. The thesis concludes with a critical discussion about the limitations of the doctoral thesis, the reference to current scientific debates, some governance recommendations, and the researcher's positioning in his research field.
