- PostIncorporation of phase changing materials (PCMs) with solar cells(2022) Smita, Smita; Mandeya, Andrew; Levin, Erik; Lizzmatz van de Laak, Marion; Chalmers tekniska högskola; Albinsson, Bo; Albinsson, BoThe increased use and scale of solar Photo-voltaic (PV) systems area increasing in the world and so are the global temperatures. As PV cells are heated, the cells lose efficiency due to a decrease in energy bandgap. Passive cooling using PCMs may counteract this effect and improve the PVs electrical power output. This report aims to investigate PV-PCM systems by performing an experimental labotary set-up and by reviewing existing theoretical models. The conducted experiment could not with any scientific certainty identify a difference although a 3.6 % increase using PCM would be observed in some instances. The theoretical model, using a day in Gothenburg with a simplified heat flux model, resulted in a 5.3 % increase in total power production during the day. While no part holds any real scientific value on its own, the results do indicate to some degree that a PV-PCM system can improve the output and further experiment and researched should be conducted to determine these effect. Finally, the report aims to reflect on the potential impact that PCMs have on the environment and the existing challenges that prevent the technology from reaching commercial scalability.
- PostIncreasing utilization of solar PV in Sweden through large-scale seasonal energy storage(2023) Andersson, Alfred; Ariaman, Pars; Viriyaparp, Intiporn; Chalmers tekniska högskola; Chalmers University of Technolog; Albinsson, Bo; Albinsson, Bo; Abrahamsson, MariaThis report examines the feasibility of integrating large-scale seasonal hydrogen storage with solar photovoltaics (PV) to facilitate the diffusion of solar PV in Sweden by allowing electricity that cannot be used directly to be utilized at a later date. Sweden’s geographical position makes it an interesting point of study because of the significant fluctuations in solar energy availability and energy demand across different seasons. Methodologically, the report is a combination of a literature search, qualitative calculations, and interviews. The results include an analysis of current technologies for converting electricity to hydrogen, hydrogen storage methods and converting hydrogen back to electricity. This is followed by a calculation that models a potential scenario of a hydrogen storagebacked solar PV system in Sweden. Lastly, a holistic review of this kind of energy system is done with societal, economic, and environmental aspects considered. The main findings of the report show that using hydrogen as an energy carrier for storing electricity might not be feasible for large-scale applications due to problems justifying it economically, which is a result of the large capital costs needed for the infrastructure to accommodate the storage demand. An alternative approach where hydrogen is utilized directly in industry instead of converting it back to electricity was found to be a more feasible solution. This could still facilitate the diffusion of solar PVs in Sweden, as the need to replace hydrogen that is sourced from fossil fuels will support this development.
- PostStrategic Assessment of Solar PV Implementation, Case Study(2022) Awad, Mohamed; Talakoob, Bahareh; Wademyr, Marcus; Mikaeili, Parinaz; Chalmers tekniska högskola; Albinsson, Bo; Albinsson, BoTo fight climate change and to strengthen the strategic sovereignty of the European energy supply, the deployment of renewables must accelerate. PV electricity is now one of the key components in the electricity mix and will contribute to more electricity production in the future. Such transformation in energy system and infrastructure can be a path of opportunity by enabling economic growth, creating jobs and reducing environmental damages and human healthcare costs by lowering pollutions. However, due to intermittency and variability of renewable energy sources, there are concerns regarding flexibility management, storage, land use and resource intensity, scarce metals, energy security, transmission reliability, market reform and fair transition for different actors and communities. Moreover, energy policies should be aligned with climate objectives and strengthening local capacities. Thus, for strategic assessment of such transformative energy plans, countries have to conduct comprehensive discussion about the kind of future societies in which energy will interact and engage in analytical assessment of environmental, societal and economic impacts to align the society with upcoming transformation. This project conveys a strategic assessment of solar PV implementation plans in Gothenburg in the context of Swedish energy plans and scenarios by 2035 and illustrates the enablers and restrictions for the set targets.
- PostSunCare Hub: A Solar-powered Portable Basic Healthcare Facility for Rural Areas(2023) Hedström, Erik; Sundbye, Caroline; Urbanos, Gonzalo; Chalmers tekniska högskola; Chalmers University of Technolog; Albinsson, Bo; Albinsson, BoRural communities are globally faced with depopulation challenges caused by urbanization, jeopardizing their role in preserving national heritage. This case study investigates the feasibility and impacts of the SunCare Hub, a solar-powered mobile healthcare facility in the context of rural areas in Spain and Sweden. The integration of monocrystalline solar panels forms the focal point, with the study undertaking an assessment of technical, social, economic, and environmental aspects. The technical analysis examines solar panel area requirements, factoring in variables like energy consumption, solar irradiance, and efficiency. Findings indicate fluctuating panel surface needs across seasons, presenting an opportunity for energy backup through battery systems. In Spain, the societal impacts concentrate on mitigating rural depopulation, aligning with Sustainable Development Goals (SDGs) such as Good Health andWell-being (SDG 3) and Sustainable Cities and Communities (SDG 11). The SunCare Hub emerges as a solution to enhance healthcare accessibility, uphold cultural identity, and contribute to the revitalization of rural areas. In Sweden, the project strategically addresses service inequalities between urban and rural regions, placing a notable emphasis on providing healthcare updates for elderly populations. Environmental considerations include the life cycle of solar panels, battery recycling processes, and solar photovoltaic (PV) recycling. Despite the energy-intensive nature of solar panel manufacturing, the short energy payback time favors their adoption over their extended lifespan. Battery recycling underscores sustainable practices, while PV recycling mitigates material depletion and toxic emissions. Economically, the study envisions a positive impact on rural repopulation, anticipating favorable outcomes for local economies, employment rates, and industry growth. The SunCare Hub’s potential to offer accessible healthcare aligns with socioeconomic benefits, reinforcing SDGs related to Reduced Inequalities (SDG 10). The study highlights the diversity of the SunCare Hub’s impact, emphasizing the imperative for holistic planning, further research, and validation to enhance sustainable healthcare solutions tailored for diverse rural communities.
- PostTransparent Photovoltaic Windows(2023) Kaminska, Kinga; Nilsson, Elin; Rehnberg, Isak; Chalmers tekniska högskola; Chalmers University of Technolog; Albinsson, Bo; Albinsson, BoThe rapid development of photovoltaics has inspired new innovative ways to capture the sun’s energy. One such measure, that has proven benefits but has remained a niche and whose future potential is relatively unknown, is transparent photovoltaics (TPV). Current research is mainly focused on integrating windows with TPV since it could lead to a significant increase of available area for photovoltaics, especially in dense cities. This project provides an overview of TPV windows utilizing CdTe thin films in order to assess the future potential of TPV windows, identify barriers that hinders the technology from diffusing and determine potential environmental impacts associated with production and utilization. The project concludes that TPV windows exhibits great potential regarding energy output in climates with high solar radiation. Development is rapid with different materials and techniques looking like viable options in the future. However, the short life-span and the challenge to maintain efficiency in larger windows hinders the technology’s diffusion. There are also signs of potential environmental impacts for CdTe TPV in the form of toxicity windows but further research is required to draw weighted conclusions.
