Renewable Energy and Energy Storage Systems
The use of fossil fuels has contributed to climate change and global warming, which has led to a growing need for renewable and ecologically friendly alternatives to these. It is accepted that renewable energy sources are the ideal option to substitute fossil fuels in the near future. Significant progress has been made to produce renewable energy sources with acceptable prices at a commercial scale, such as solar, wind, and biomass energies. This success has been due to technological advances that can use renewable energy sources effectively at lower prices. More work is needed to maximize the capacity of renewable energy sources with a focus on their dispatchability, where the function of storage is considered crucial. Furthermore, hybrid renewable energy systems are needed with good energy management to balance the various renewable energy sources’ production/consumption/storage. This work covers the progress done in the main renewable energy sources at a commercial scale, including solar, wind, biomass, and hybrid renewable energy sources. Moreover, energy management between the various renewable energy sources and storage systems is discussed. Finally, this work discusses the recent progress in green hydrogen production and fuel cells that could pave the way for commercial usage of renewable energy in a wide range of applications
Natural and Technological Hazards in Urban Areas
Natural hazard events and technological accidents are separate causes of environmental impacts. Natural hazards are physical phenomena active in geological times, whereas technological hazards result from actions or facilities created by humans. In our time, combined natural and man-made hazards have been induced. Overpopulation and urban development in areas prone to natural hazards increase the impact of natural disasters worldwide. Additionally, urban areas are frequently characterized by intense industrial activity and rapid, poorly planned growth that threatens the environment and degrades the quality of life. Therefore, proper urban planning is crucial to minimize fatalities and reduce the environmental and economic impacts that accompany both natural and technological hazardous events
R-strategies in circular economy : Textile, battery, and agri-food value chains
This report discusses the circular economy model through circular economy strategies, the R-strategies, in three different value chains: textile, battery, and agri-food.
The R-strategies can be classified under three approaches: 1) smarter product use and manufacture (R0 Refuse, R1 Rethink, R2 Reduce), 2) life extension strategies (R3 Reuse, R4 Repair, R5 Refurbish, R6 Remanufacture, R7 Re-purpose), and 3) creative material application (R8 Recycle, R9 Recover). Often, the impact on circularity and overall sustainability is likely higher in the beginning of the material value chain. However, the selection of the most optimal R-strategy is always case specific and should be based on a holistic, system wide approach.
The report gives several examples of business models applying different R-strategies in the selected value chains. The examples show the similarities and differences between the value chains and which strategies have more importance in which value chains.
In the textile value chain, currently the most important aim is to replace fast fashion with longer product use (R3, R4, R5) and essentially reduce production and consumption volumes (R0, R1, R2). Textile fibres can be circulated (R6, R7, R8) to some extent, but in every round, there is some wearing of the material and the quality of the recycled fibre deteriorates in comparison to virgin fibre.
In the battery value-chain, increased recycling of metals (R8) is crucial to meet the future need of batteries in various solutions including electric vehicles and energy storage. Thus, recycling technologies need to be further developed to meet the recycling targets. There is also active research and development activities in the field of substitution (R0) with new battery chemistries and even replacing graphite with renewable lignin-based material.
In the agri-food value chain, avoiding food loss and food waste (R0) is clearly a low hanging fruit since even one third of all food is estimated of being wasted. When it comes to circularity in the agri-food value chain, it is best supported by increasing local food production, where transport distances are short and do not create a barrier for efficient utilization of side-streams (R8, R9). The circulation of nutrients in manure is also essential
Statistical characterisation of public AC EV chargers in the UK
In recent years, the public AC electric vehicle (EV) charging network in the United Kingdom (UK) has experienced significant growth, more than doubling in size. However, there remains a significant lack of information regarding usage patterns, which hampers decision-making for future infrastructure planning. This study addresses this gap by presenting a statistical analysis based on data from nearly twelve thousand EV charging sessions. The data was collected from 595 AC charging sockets, with 85% operating at 7 kW and the remaining 15% at 22 kW, throughout the UK between April 2022 and July 2022. The analysis focuses on key factors that define the primary characteristics of the current public EV charging ecosystem, including utilisation rates, arrival-departure times, sojourn durations, energy transfer, and overstay durations. Several important observations are made, such as the variability in utilisation rates, factors influencing overstay periods, and peak demand periods. With two case studies, the potential role of smart charging in leveraging EV flexibility is shown by lowering and shifting the peak EV loads. The findings of this study have significant implications for the planning and efficient allocation of investments to expand the charging infrastructure. By gaining a better understanding of the current charging ecosystem, informed decisions can be made to optimize the usage and expansion of EV charging facilities
Innovation in Energy Security and Long-Term Energy Efficiency â…ˇ
The sustainable development of our planet depends on the use of energy. The increasing world population inevitably causes an increase in the demand for energy, which, on the one hand, threatens us with the potential to encounter a shortage of energy supply, and, on the other hand, causes the deterioration of the environment. Therefore, our task is to reduce this demand through different innovative solutions (i.e., both technological and social). Social marketing and economic policies can also play their role by affecting the behavior of households and companies and by causing behavioral change oriented to energy stewardship, with an overall switch to renewable energy resources. This reprint provides a platform for the exchange of a wide range of ideas, which, ultimately, would facilitate driving societies toward long-term energy efficiency
Carbon-Free Power
There is a new world order in electrical energy production. Solar and wind power are established as the low-cost leaders. However, these energy sources are highly variable and electrical power is needed 24/7. Alternative sources must fill the gaps, but only a few are both economical and carbon-free or -neutral.
This book presents one alternative: small modular nuclear reactors (SMRs). The authors describe the technology, including its safety and economic aspects, and assess its fit with other carbon-free energy sources, storage solutions, and industrial opportunities. They also explain the challenges with SMRs, including public acceptance.
The purpose of the book is to help readers consider these relatively new reactors as part of an appropriate energy mix for the future and, ultimately, to make their own judgments on the merits of the arguments for SMRs.Publishe
