This article focuses on the challenge of upscaling, with illustrative examples from the DIACCESS project. In that project, the Swedish city of Växjö is developing a range of smart city innovations, and it has developed a vision on how these innovations can be scaled up.

While modern wind turbines have become by far the largest rotating machines on Earth with further upscaling planned for the future, a renewed interest in small wind turbines (SWTs) is fostering energy transition and smart grid development. Small machines have traditionally not received the same level of aerodynamic refinement as their larger counterparts, resulting in lower efficiency, lower capacity factors, and therefore a higher cost of energy. In an effort to reduce this gap, research programs are developing worldwide. With this background, the scope of the present study is 2-fold. In the first part of this paper, an overview of the current status of the technology is presented in terms of technical maturity, diffusion, and cost. The second part of the study proposes five grand challenges that are thought to be key to fostering the development of small wind turbine technology in the near future, i.e. (1) improving energy conversion of modern SWTs through better design and control, especially in the case of turbulent wind; (2) better predicting long-term turbine performance with limited resource measurements and proving reliability; (3) improving the economic viability of small wind energy; (4) facilitating the contribution of SWTs to the energy demand and electrical system integration; (5) fostering engagement, social acceptance, and deployment for global distributed wind markets. To tackle these challenges, a series of unknowns and gaps are first identified and discussed. Based on them, improvement areas are suggested, for which 10 key enabling actions are finally proposed.

In many cities, pilot projects are set up to test new technologies that help to address urban sustainability issues, improve the effectiveness of urban services, and enhance the quality of life of citizens. These projects, often labelled as “smart city” projects, are typically supported by municipalities, funded by subsidies, and run in partnerships. Many of the projects fade out after the pilot stage, and fail to generate scalable solutions that contribute to sustainable urban development. The lack of scaling is widely perceived as a major problem. In this paper, we analyze processes of upscaling, focusing on smart city pilot projects in which several partners—with different missions, agendas, and incentives—join up. We start with a literature review, in which we identify three types of upscaling: roll-out, expansion, and replication, each with its own dynamics and degree of context sensitivity. The typology is further specified in relation to several conditions and requirements that can impact upscaling processes, and illustrated by a descriptive analysis of three smart city pilot projects developed in Amsterdam. The paper ends with conclusions and recommendations on pilot projects and partnership governance, and adds new perspectives on the debate regarding upscaling.
Aiming for a more sustainable future, biobased materials with improved performance are required. For biobased vinyl polymers, enhancing performance can be achieved by nanostructuring the material, i.e. through the use of well-defined (multi-)block, gradient, graft, comb, etc., copolymer made by controlled radical polymerization (CRP). Dispoltec has developed a new generation of alkoxyamines, which suppress termination and display enhanced end group stability compared to state-of-art CRP. Hence, these alkoxyamines are particularly suited to provide access to such biobased nanostructured materials. In order to produce alkoxyamines in a more environmentally benign and efficient manner, a photo-chemical step is beneficial for the final stage in their synthesis. Photo-flow chemistry as a process intensification technology is proposed, as flow chemistry inherently leads to more efficient reactions. In particular, photo-flow offers the benefit of significantly enhancing reactant concentrations and reducing batch times due to highly improved illumination. The aim of this project is to demonstrate at lab scale the feasibility of producing the new generation of alkoxy-amines via a photo-flow process under industrially relevant conditions regarding concentration, duration and efficiency. To this end, Zuyd University of Applied Sciences (Zuyd), CHemelot Innovation and Learning Labs (CHILL) and Dispoltec BV want to enter into a collaboration by combining the expertise of Dispoltec on alkoxyamines for CRP with those of Zuyd and CHILL on microreactor technology and flow chemistry. Improved access to these alkoxyamines is industrially relevant for initiator manufacturers, as well as producers of biobased vinyl polymers and end-users aiming to enhance performance through nanostructuring biobased materials. In addition, access in this manner is a clear demonstration for the high industrial potential of photo-flow chemistry as sustainable manufacturing tool. Further to that, students and professionals working together at CHILL will be trained in this emerging, industrially relevant and sustainable processing tool.
DISCO aims at fast-tracking upscaling to new generation of urban logistics and smart planning unblocking the transition to decarbonised and digital cities, delivering innovative frameworks and tools, Physical Internet (PI) inspired. To this scope, DISCO will deploy and demonstrate innovative and inclusive urban logistics and planning solutions for dynamic space re-allocation integrating urban freight at local level, within efficiently operated network-of-networks (PI) where the nodes and infrastructure are fixed and mobile based on throughput demands. Solutions are co-designed with the urban logistics community – e.g., cities, logistics service providers, retailers, real estate/public and private infrastructure owners, fleet owners, transport operators, research community, civil society - all together moving a paradigm change from sprawl to data driven, zero-emission and nearby-delivery-based models.
The program is structured in five tasks, of which three are technical by nature and two are on integration and enabling aspects. The technical tasks are infrastructure, offshore and large-scale storage of hydrogen. The enabling task is safety, standardization and regulation, which is a key boundary condition for the successful development of a hydrogen infrastructure. As overarching task the aspect of upscaling and system integration is analysed. Both the enabling and overarching tasks are strongly linked to the technical tasks and require active interaction between those tasks to be successful. Our consortium enables productive interactions by facilitating knowledge sharing, joint research projects, technology transfer, policy advocacy, public engagement, and standardization efforts. These interactions not only enhance the research and development outcomes within the consortium but also contribute to the broader societal and economic benefits of a hydrogen-based energy transition.
