Economically sustainable development of wave and tidal stream energy technologies

MacGillivray, Andrew John January 2016 (has links)
The wave and tidal energy sectors have received much interest in recent years, from policy-makers attentive to the prospect that ocean energy technologies could be capable of contributing towards meeting environmental targets; from utility companies that expressed interest in developing, constructing and operating array projects to export large quantities of clean energy from ocean based resources; and from Small to Medium Enterprises (SMEs) and large multi-national Original Equipment Manufacturers (OEMs) that were interested in undertaking technological development to commercialise wave and tidal energy converters that could successfully harness the energy contained within the ocean waves and tides. Within the existing research, development and innovation environment that has largely dominated the development of wave and tidal energy to date – rapid development of large MW-scale devices capable of utility scale power generation – technology developers have failed to reach the level of deployed capacity that was initially anticipated, despite the significant level of investment that has taken place. Indeed, the expected contribution of ocean energy in the wider energy mix, which has been written into policy documentation at both national and European level, has so far failed to materialise in the form of prolific multiple device array deployments. The research, development and innovation environment has not delivered on its intended objective of demonstrating commercial technology readiness, and the historic development trajectories for ocean energy technologies may not represent the most cost-effective route to product commercialisation. This research explores the wave and tidal energy research, development, and innovation environment through extensive stakeholder engagement within the ocean energy sector, and through application of suitable techniques from innovation theory. The purpose of this research was three-fold. Firstly, an objective analysis of the development of the wave and tidal energy sectors – building a comprehensive understanding of their development to date through extensive stakeholder engagement, and comparing wave and tidal energy technology development with that of historic energy technologies that have successfully entered into commercial operation – was necessary in order to identify whether the attempt by ocean energy technologies for rapid up-scaling of technology is consistent with the development pathway that was followed by energy technologies which have successfully transitioned from novel invention to full commercial operation. This work identified several dichotomies that are present in the nascent stages of technology development in the wave and tidal energy sectors. Secondly, the uncertainties surrounding existing capital and revenue costs, and the uncertainties within the potential future cost reductions associated with current technology trajectories, could lead to unsustainable investment requirements. Commercialisation of wave and tidal energy technology is predicated upon significant cost reduction – the current technology costs are not feasible for large scale roll out of technology. A research focus on the economic uncertainty through application of learning theory and a learning investment sensitivity analysis was anticipated to demonstrate the economic impact of minor perturbations from idealised reference assumptions. The results from this work suggest that even minor perturbations in input parameters have substantial negative impact on overall investment requirements to bring technology to a level of cost competitiveness. Thirdly, the policy landscape surrounding wave and tidal energy development has not been specifically compared and contrasted, using a number of performance metrics, to a technology which was subject to similar expectations in the form of income streams – wind energy technology. The causes and motivations for the rapid transition to large-scale technologies and ‘accelerated innovation’ within ocean energy technology were considered within this research, which suggested that a mismatch between policy support and technological readiness could misguide and misdirect the innovation pathway, harming the commercialisation prospects of ocean energy technology. In order for the successful emergence of economically sustainable wave and tidal energy technologies, a paradigm shift may be necessary, a change from the current approach that has to date dominated technological development within both the wave and tidal energy sectors. This research draws together industry consultation with academic insight to identify an optimised innovation pathway, culminating in a policy appraisal to guide and inform economically sustainable development of wave and tidal energy technologies.

Kvinnorörelsen och efterkrigsplaneringen : statsfeminism i svensk arbetsmarknadspolitik under och kort efter andra världskriget / The feminist movement and post-war planning : state feminism in the Swedish labour market policy during and shortly after the second world war

Almgren, Nina January 2006 (has links)
This thesis has analysed the relations among the women’s movement, the state and the labour market policy during and shortly after the Second World War and to what extent this period can be characterised as a formative phase as regards gender relations. The aim has been to study women’s strategic actions in order to influence the Swedish Government’s labour market policy in the period from 1939 to 1947. The thesis shows the conflicts of interest that manifested themselves between Statens arbetsmarknadskommission (SAK, ‘the National Swedish Labour Market Commission’) and its advisory women’s group, experts on women’s issues, concerning the planning and utilisation of female labour. SAK thought that the work of the experts on female issues should only focus on the short-term labour problems caused by the national crisis situation, while the experts on women’s issues were of the opinion that they should also work with long-term labour-market issues for women. These different ways of thinking and understanding the problem originated in different views on women’s work. The experts on women’s issues wanted to strengthen women’s position on the labour market by abolishing the wage differences between the genders, breaking the gender segregation in education, and broadening the occupational choices of girls. They had three strategies for achieving this: a strategy of professionalisation, a strategy of change, and a strategy of state feminism. The strategy of professionalisation was aimed at raising the value of traditional female work, in terms of both status and wages. The strategy of change was aimed at creating new opportunities for women to leave typical low-wage jobs and gain access to better paid jobs in male-dominated areas. The strategy of state feminism was aimed at paving the way for women in new and expanding occupational areas beside the traditional male occupations. Can the period during and shortly after the war be characterised as a formative phase of the issue of gender relations? It is evident that this period did not involve a revolution of the societal gender order. The idea of women as reserve labour did not disappear. The post-war planners considered that, in the transition to peace, the women who had replaced men who were called up should be redeployed or retrained for employment in household work, in hotels, restaurants and cafés, in shops and in health care. In spite of the great shortage of labour in the post-war period, leading politicians and economists stuck to old ways of thinking. A clear indication on the part of the Government was that the women’s movement’s demand for long-term planning in order to utilise female labour was turned down. One important difference from the First World War was that the Government produced peace plans for women’s work during the Second World War. The period also led to ideological and institutional consequences that could be the beginning of a change of the societal gender order. From her central position in Kommissionen för ekonomisk efterkrigsplanering (‘the Commission for economic post-war planning’), Karin Kock could see to it that women’s demands for greater occupational mobility and a loosening up of the gender division of labour had an impact on the post-war planning of the war years. The experiences of women in male industries in the Second World War, both in Sweden and abroad, showed to some extent that it was possible to change the gender division of labour. The modern welfare state also came to correspond to a great extent to the state feminist strategy of the experts on women’s issues. With the historical formation of the welfare state a new type of occupational groups developed, the so-called welfare state professionals.
