Title: Power optimization strategies

Abstract:

The aim of this paper is to analyze the factors affecting hydrogen and Carbon Capture and Storage Technologies (“CCS”) policies, taking into consideration Fossil Fuel Consumption, Oil Reserves, the Debt/GDP Ratio, the Trilemma Index and other variables with respect to OECD countries. STATA 17 was used for the analysis. The results confirm the hypothesis that countries with high fossil fuel consumption and oil reserves are investing in blue hydrogen and CCS towards a “zero-carbon-emission” perspective. Moreover, countries with a good Debt/GDP ratio act most favorably to green policies by raising their Public Debt, because Foreign Direct Investments are negatively correlated with those kinds of policies. Future research should exploit Green Finance policy decision criteria on green and blue hydrogen.

Title: Impact of renewable energy on environments

Abstract:

Date palm trees, being an important source of nutrition, are grown at a large scale in Saudi Arabia. The biomass waste of date palm discarded in a ungreen manner at present, can be used for biofuel generation through fast pyrolysis technique. This technique is considered viable for thermochemical conversion of solid biomass into biofuels in terms of initial investment, production cost, operation cost as well as power consumption and thermal application cost. In this study, a techno economic analysis has been performed to assess the feasibility of converting date palm waste into bio-oil, char and burnable gases by defining the optimum reactor design and thermal profile. The results from the previous studies concluded that at an optimum temperature of 525oC, the maximum bio-oil, char and gases obtained from pyrolysis of date palm waste contributed 38.8, 37.2 and 24% of the used feed stock material (on weight basis) respectively, while fluidized bed reactor exhibited high suitability for fast pyrolysis. Based on the pyrolysis product percentage, the economic analysis estimated the net saving of US$ 556.8 per ton of the date palm waste processed in the pyrolysis unit. It was further estimated that Saudi Arabia can earn US$ 44.77 million per annum, approximately, if 50% of the total date palm waste is processed through fast pyrolysis with a payback time of 2.57 years. Besides that, this intervention will reduce 3618 tons of greenhouse gas emissions annually, contributing towards a lower carbon footprint.

Title: Photovoltaic array on highway pavement under the dynamic random vehicle shading conditions

Abstract:

 The objective of two-stage SD-MILP is modeled as a convex combination of the expected profit and the T-CVaR hourly risk measure. When day-ahead, intra-day and real-time market prices and fleet mobility are uncertain, the proposed two-stage SD-MILP model yields optimal EV charging/discharging plans for day-ahead, intra-day and real-time markets at per device level. The degradation costs of EV batteries are precisely modeled. To reflect the continuous clearing nature of the intra-day and real-time markets, rolling planning is applied, which allows re-forecasting and re-dispatching. The proposed two-stage SD-MILP is used to derive a bidding curve of an aggregator managing 1000 EVs. Furthermore, the model statistics and computation time are recorded while simulating the developed algorithm with 5000 EVs.

Title: Ecosystem services in pasture by shelter created from the hybrid sterile bioenergy

Abstract:

Recent years have seen a significant increase in interest in mangrove biodiversity and conservation due to better awareness of the values, functions, and features of mangrove ecosystems as a result of scientific investigation. Mangrove forests are a unique coastal ecosystem defined by their specific adaptations that allow them to live abundantly in brackish water and saline soil, on sheltered shores that undergo fresh and salt-water influx regularly. Despite accounting for only about 1% of global forest coverage, mangroves are keystone ecosystems that provide a variety of critical ecological processes and environmental services to both terrestrial and marine biomes. Even though mangroves play an important role in the global carbon cycle and climate change, their extent has inexorably decreased in recent decades. It is mostly because of human activities such as aquaculture expansion, coastal development, and overharvesting that the population has declined. As a result of recent years' efforts, global society has become more mindful of and concerned about the subject of climate change, particularly global warming. It has been particularly noticeable in recent years that global warming is present and having an impact on human comforts, as well as its existence and effects. Heat waves, forest fires, sea level rise, pollution, habitat loss, and a reduction in biodiversity resources are just a few of the extreme events that have occurred recently to highlight the presence of global warming. On the other hand, the mangrove species at risk are the main concern to be conserved and preserved for future generations. The study aims to promote coastal and mangrove forest conservation and natural and cultural value preservation through the rehabilitation of swamp forests (mangrove) in the north coast area of Malaysia. This project directly promotes the achievement of sustainable development goals (SDGs) through the rehabilitation and restoration of degraded ecosystems and the promotion of the recovery of threatened mangrove species. This research will rely on case studies and observations of a rehabilitation project on Malaysia's north coast. Observational monitoring of key indicators is important to determine the performance of rehabilitation or restoration projects' aims and objectives, as well as to guide adaptive management and decision-making.

To achieve this objective, additional investment and commitment to research and adaptive management methods would be required. These concepts are illustrated through case studies of mangrove restoration and rehabilitation programmes in the northern coastal area of Malaysia, which are both hotspots for mangrove biodiversity and are experiencing ongoing loss and degradation. The results demonstrated that the success of the mangrove rehabilitation project and the number of endangered species restored will determine the expected outcome. This current study has both practical and social implications. Regarding the practical contribution, the countries should strengthen the legislative framework for management of mangrove diversity and conservation.

Title: Pyrolysed Residual Biomass as a Substitutional Fuel for Iron Ores Sintering Process

Abstract:

The paper presents results of the research on the use of chars produced during pyrolysis of residual biomass as a substitutional fuel in the iron ore sintering process. Such the approach allows to implement circular economy and industrial symbiosis to iron and steel branch. The effect of the substitution of conventional coke breeze fuel used in sintering on final sinter quality and emission was examined. In regard to productivity, fuel consumption and properties of the sinter it was shown, that the share of tested biochars in fuel may be kept at 10 up to 30wt.%, depending on the biochar type. It was observed, that with the use of the biochars, the content of iron oxide in the sinter decreased, what was advantageous. Moreover, the sinter obtained at the presence of biochars characterized with better strength and abrasion than the sinter obtained with coke breeze based fuel improving the final product quality. The presence of biochar influenced on raw exhaust gas composition and resulted in slight increase of organic and inorganic carbon compounds content, while the amount of sulphur oxides was noticeably decreased. It was concluded the biochars may be applied in sintering process at established share in the fuel stream.

Title: Urban wastewater treatment in African countries: Evidence from the hydroaid initiative

Abstract:

The main aim of this study was to clarify the current literary inconsistencies regarding the characteristics of entrepreneurial leadership and its impact on sustainability. Additionally, another aim was to establish the framework of entrepreneurial leadership and to highlight the main gaps in the entrepreneurial leadership literature. The entrepreneurial leadership literature started to develop recently as a new leadership style that is required to fulfill the current business changes in the fourth industrial revolution. The researchers conducted a narrative literature review to assess the status of entrepreneurial leadership in academia, literature gaps, and the impact of entrepreneurial leadership on the sustainability performance of organizations. Furthermore, the researchers main aim was to investigate the following research question: is entrepreneurial leadership a fixed or a multidimensional concept that differs based on industry, context, and firm size? Regarding the answer to this question, the current study found that entrepreneurial leadership is a multidimensional concept as it is reflected in different perspectives, which indicates the inconsistency of the characteristics of entrepreneurial leadership claimed in the literature. Research limitations—the current study focused on assessing the literature review status of entrepreneurial leadership. Based on that, this study’s limitation is represented in not focusing on testing entrepreneurial leadership’s impact on sustainability either quantitatively or qualitatively. On the contrary, it contributed by analyzing the status of the entrepreneurial leadership literature. Future studies need to further assess this relationship between both concepts and reach an agreement about the common characteristics of entrepreneurial leadership. Originality/value—the current study contributes to the entrepreneurial leadership literature as it highlighted the existing gaps and the inconsistency in the literature. Additionally, it contributed theoretically by connecting entrepreneurial leadership to the existing literature. Furthermore, empirically, it highlighted the contribution of entrepreneurial leadership by emphasizing the impact of it on organizational sustainable development performance. This study represents a call for scholars to focus more on entrepreneurial leadership given its contribution to organizational performance.

Title: Research on power optimization strategies of photovoltaic array on highway pavement under the dynamic random vehicle shading conditions

Abstract:

As a new trend of photovoltaic (PV) power generation comprehensive utilization project, "PV + expressway" is in the embryonic stage of development. Compared with the traditional PV power generation system, the shadow distribution of vehicles with strong random uncertainty and rapid change speed is formed by the high-speed driving vehicles in the PV highway. On the one hand, it is easy to induce the series and parallel mismatching of the pavement PV arrays, resulting in the power losses. On the other hand, it leads to the complex fast changing multi peak phenomenon of the output characteristics of the pavement PV arrays, increases the difficulty of maximum power point tracking control, and further intensifies the power losses. In order to solve the above problems, this project takes highway the pavement PV array as the research object, explores vehicle shadow distribution of PV highway based on vehicle traffic flow theory, establishes multi scene mathematical model of highway pavement PV array, analyzes output characteristics and maximum power point distribution of the pavement PV array under dynamic random vehicle shadow, and studies the optimal design of the pavement PV array configuration based on the reverse analysis method and the maximum power point tracking strategy of the pavement PV array based on self leading algorithm library. The purpose of this project is to reduce the power loss of the highway pavement PV array under the shadow of dynamic random vehicles, improve the power generation efficiency of pavement PV array, and lay a theoretical foundation for the development and application of PV highway, which has important engineering value and scientific significance.
