Regulatory Paradigm and Challenge for Blockchain Integration of Decentralized Systems: Example—Renewable Energy Grids

Nowadays, fossil fuels are used in a clearly unsustainable way that can bring potentially catastrophic consequences. Electricity is currently delivered to end users by generation and energy transmission companies. Previous research shows that the development of modern circular economy sets a need for the re-orientation of socio and economic development of decentralized systems, including energy basis. In addition to being ecological, the use of renewable energy sources also has economic significance by contributing to energy independence. Citizens, industries, local and national authorities become interconnected within emerging novel renewable energy sourcing communities, through which they establish trade of energy and, most importantly, models of investing and reshaping the distribution of renewable energy. The modern portfolio management of renewable energy networking is aiming toward decentralized systems of trade, where the consumer becomes a producer (prosumer) within the network, itself managed by users. Excess energy produced in the micro-grid nets within the over-arching national and transnational energy grid should be accounted for and managed with blockchain technology for financial and structural security. The decentralization of the energy market requires the establishment of strict norms that will regulate the market and taxation of profits arising. The extensive literature review on blockchain in the energy sector reflects a very pragmatic and narrow approach to the topic, although it is evident that the distribution of energy within the blockchain would enable economic development through reducing cost and ensuring more secure energy trade. Blockchain technology embeds the related digital codes, in which information will be visible to all, but also secured from hacking and duplicating. However, there are challenges to this paradigm, not least the energy consumption of the extensive nodal mesh required to perform the necessary protocols. This paper aims to provide an overview of the application of blockchain technology and the need for the development of the regulatory system and of potential solutions to the challenges posed. By undertaking an energy consumption analysis of blockchain implementation from first electronic principles, which has not been constructed before in the literature, this paper’s conclusion stresses the future demand for reducing energy consumption and considers the latest findings in the quantum coupling of light signals as a potential for solving the enormous ledger duplication structure problem

Sustainability challenge on pollution and air quality inside heavy-duty vehicle cabins

Air quality in transportation vehicle cabins is becoming a major concern due to increasing exposure of drivers to harmful gases and aerosol, especially if having in mind that that safety and pollution are positively correlated and adverse events. In order to reduce exposure to air pollution, there is ongoing development of air filters in modern heavy-duty vehicles and increase in protective regulations throughout the world. The aim of this study is to gain insight into extent of pollutants in heavy-duty vehicle cabins, in which drivers spend a large amount of their working (and spare) time, and the necessity for use of air filtration systems. Both experimental results and modelling approach applied in this manuscript reveal the importance of filtration of cabin air, and indicate good correlation between experimental and mathematical results from field measurements conducted in a highly polluted city. Namely, this paper reveals excellent results with the HECA filter which have potential to significantly reduce pollution in the cabin

Filtering Efficiency of Pollutants in Heavy-Duty Vehicle Cabins

Quality of air in the cabin of transportation vehicle is of high importance due to increase in globalization that hinders rise of transportation of goods worldwide. The largest source of streets pollution in urban areas is vehicular combustion, constituted mainly of gaseous pollutants such as CO2, CO, oxides of nitrogen (NOx), ozone, and particles such as ultra-fine particulate matter (UFP). Drivers of heavy-duty vehicles (HDV) are spending both their working and free time in vehicle cabins, making then highly exposed to toxic gases and hazardous aerosols. Intensive industrial development is more concentrated in metropolitan areas, and since it still relies on fossil fuels energy, it results in high pollution of air with traf- fic-related air pollutants (TRAPs). Primary sources of UFPs in the urban environment near road sites are caused by HDV, and they enter cabin air through windows, accumulating in the cabin air and on the surfaces, resulting of up to three times higher concentration of TRAPs in cabin than outdoor air. Exposures to high CO2, NOx and UFP can significantly reduce decision-making performance and is main cause of premature deaths of HDV drivers. Sedimentation of UFP onto filter surfaces, long filter exposure times, and high temperatures within cabins cause decrease of air-flow within the filter and drastic decrease of filtering efficiency. By combining experimental results obtained from in-filed measurements performed in the city of Belgrade, during peak traffic hours, for filtration systems (AFS) placed at different positions within the cabins, obtained master present role of air filtration systems. Using analytical approach of experimental results, we propose mathematical model that describes AFS efficiency on cabin pollution mitigation. Predicted results are in close agreement with the experimental data showing that outdoor to cabin pollutants concentration is possible to estimate as it depends on and terrain design, filtration time and thermodynamic parameters within cabin. We hope that this research rises organizational attention to the health and welfare of HDV drivers
