Development of innovative small(micro)-scale biomass-based CHP technologies
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- To enhance the overall efficiency of the use of biomass in the energy sector in Europe, the large electricity production potential from small-scale biomass heating systems should be utilised. So far, no technologically sound (in terms of efficiency and reliability) and economically affordable micro- and small-scale biomass CHP technologies are, however, available. Therefore, the present ERA-NET project (MiniBioCHP) aimed at the further development and test of new CHP technologies based on small-scale biomass combustion in the electric capacity range between some W and 100 kW. Within the project, an international consortium consisting of 12 partners from 4 countries, including university institutions, institutes and industry (both engineering and manufacturing), collaborated closely to perform high level R&D on three promising micro/small-scale biomass based CHP technologies which are covering a broad range of applications in the residential heating sector. The Austrian engineering company BIOS, coordinated the international project. The project was based on earlier basic research and development work related to these promising new technologies and aimed at the achievement of a technological level which allows a first (commercial) demonstration after the end of the project. The three CHP concepts included in the MiniBioCHP project were;1. Pellet stoves with a thermoelectric generator (TEG)2. Small-scale biomass boilers (10-30 kWth) with a micro-ORC process3. High temperature heat exchanger (HT-HE) for an externally fired gas turbine (EFGT)The Swedish part of the project was focused on the development of the concept of biomass based EFGT with dedicated R&D activities related to the development of the HT-HE system. The Swedish project consisted of the research partners Umeå University (project leader), Luleå University of Technology, Chalmers University of Technology and RISE Research Institutes of Sweden, together with the industrial partners Enertech AB/Osby Parca and Ecergy. The expertise of the Swedish partners regarding ash related problems, grate boiler combustion and modelling, deposit formation and high temperature corrosion, were combined with the know-how of a Polish partner regarding HT-HE design, construction, testing and optimisation.The HT-HE is the most crucial component in EFGT processes significantly influencing the investment costs, availabilities as well as the efficiencies that can be achieved. With a thermal capacity from several hundred kW up to 2-3 MWth) the CHP technology based on a biomass boiler and an EFGT is suitable for district heating systems, or process heat consumers. The electricity produced by the gas turbine (up to some 100 kWel) can be used to cover the own electricity consumption of a company and/or fed into the grid. Even though the concept of biomass based EFGT has been an interesting alternative for small-scale CHP production for some decades, and R&D activities have been undertaken, tackling both economic and technical aspects, only a few pilot-plants have been in operation and no initiative has so far reached the level of commercial implementation. Thus, the concept of EFGT fed with biomass is still considered to be in a rather early development stage and the main technical challenges are related to alkali deposit induced corrosion and thermal stress of the HT-HE material, turbine design/operation and system integration.Within the present project, a HT-HE prototype aimed for an EFGT system was therefore designed, constructed and successfully tested at flue gas temperatures up to 900°C. Thus, appropriate guidelines for a compact design of the HT-HE and recommendations have been worked out to minimize thermal stresses as well as ash related problems regarding ash deposit formation and high temperature corrosion in a biomass boiler system. Furthermore, different concepts for the overall biomass based EFGT system have been worked out and evaluated. The outcome of the project will hopefully be used in the further development work and form the basis for a first testing and demonstration plant within the coming years.

Why Diverse Top Management Teams Break up in Post-acquisition Periods
- 2015
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper proposes a complementary explanation behind the turnover of target’s top managers in post-acquisition periods. Although human capital and acquisition implementation literature describe managerial retention as desirable, empirical studies have reported significant managerial turnover in acquisition of high-tech and knowledge intensive firms. Borrowing some insights from the team diversity literature, the paper examines the ex-ante diversity among top managers of knowledge-intensive and high-tech firms as an antecedent of their turnover in post-acquisition. We argue that diversity reduces the coordination efficiency necessary to transfer knowledge and facilitate post-acquisition organizational integration, and managers belonging to such teams are more likely to be replaced. Empirical analysis drawing on 2164 top managers in 297 Swedish firms shows that managerial position diversity as a separation, pay disparity and industrial tenure diversity as a variety indeed are associated with managerial exit in three years after the acquisition.

Academic Entrepreneurship : The Bayh-Dole Act versus the Professor's Privilege

Tidskriftsartikel (refereegranskat)abstract
- Is the Bayh-Dole intellectual property regime associated with more and better academic entrepreneurship than the Professor's Privilege regime? The authors examine data on US PhDs in the natural sciences, engineering, and medical fields who became entrepreneurs in 1993-2006 and compare this to similar data from Sweden. They find that, in both countries, those with an academic background have lower rates of entry into entrepreneurship than do those with a non-academic background. The relative rate of academics starting entrepreneurial firms is slightly lower in the United States than in Sweden. Moreover, the mean economic gains from becoming an entrepreneur are negative, both for PhDs originating in academia and for non-academic settings in both countries. Analysis indicates that selection into entrepreneurship occurs from the lower part of the ability distribution among academics. The results suggest that policies supporting entrepreneurial decisions by younger, tenure-track academics may be more effective than are general incentives to increase academic entrepreneurship.

Tidskriftsartikel (refereegranskat)abstract
- This study investigates how research group characteristics relate to the early career success of PhD candidates who are trained in the group. In particular, I study how the citation impact of early-career PhDs is related to the staff composition and funding of the group. Using data on a cohort of Swedish doctoral graduates in science, engineering, mathematics and medicine, two sets of findings are obtained. First, students who were trained in groups with a lower number of PhD students perform better in terms of academic productivity. From the perspective of research policy, this finding suggests a decreasing return to funding additional PhD student positions allocated to professors who are already maintaining larger research groups. Second, PhD students trained in groups with funding for PhD research that is conditioned by funder influence over the topic of thesis research are more likely to stay in academia. Controlling for career destination, however, PhDs from such groups have lower than average scientific productivity and citation impact. These results suggest that finders of PhD studies face a trade-off between the two different funding objectives of "getting what they want" in terms of research content and fostering successful scholars.

Concluding Discussion : The Past, Present, and Future of Technical Universities
- 2020. - 1
-
Ingår i: Technical Universities. - Cham : Springer Nature. ; , s. 227-242
-
Bokkapitel (refereegranskat)abstract
- Higher education institutions identified as ‘technical universities’ enjoy considerable status in many countries. Yet studies of boundary negotiations from a range of settings suggest that opportunities to transform into a broader, research-based university often takes precedence over the alternative vision of remaining or moving towards becoming a focused technical university. In this chapter, we discuss alternative explanations for the lacklustre appeal of the latter type of institutional template, and outline a roadmap for how the historical legacy of the technical university may be cultivated.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter analyzes why large multinational firms are willing to invest resources in long-term collaboration with leading universities. This chapter is based on interviews with the multinationals at universities in Sweden, Switzerland, and the United Kingdom. The issue of how and why multinational corporations are willing to invest in longer-term collaboration with universities relates back to the core of the ‘positive’ interpretation of the knowledge society for Europe – namely how to remain attract node for R&D. This chapter thus moves to the perspective of the firm, in their interactions with university-based researchers active in top universities in different fields.

Engaging Experts : Science-Policy Interactions and the Introduction of Congestion Charging in Stockholm

Ingår i: Minerva. - : SPRINGER. - 0026-4695 .- 1573-1871 .- 1393-614X. ; 56:2, s. 183-207

Tidskriftsartikel (refereegranskat)abstract
- This article analyzes the conditions for mobilizing the science base for development of public policy. It does so by focusing upon the science-policy interface, specifically the processes of direct interaction between scientists and scientifically trained experts, on the one hand, and agents of policymaking organizations, on the other. The article defines two dimensions - cognitive distance and expert autonomy - which are argued to influence knowledge exchange, in such a way as to shape the outcome. A case study on the implementation of congestion charges in Stockholm, Sweden, illustrates how the proposed framework pinpoints three central issues for understanding these processes: (1) Differentiating the roles of, e.g., a science-based consultancy firm and an academic environment in policy formation; (2) Examining the fit between the organizational form of the science-policy interface and the intended goals; and (3) Increasing our understanding of when policymaker agents themselves need to develop scientific competence in order to interact effectively with scientific experts.
