Energy is a basic requirement for development in the world. The continuously rising demand for energy resources and the fast depletion of fossil fuel is raises researcher’s concern to focus on alternative sources of energy that can replace the shortage of fossil fuels soon. Biodiesel is recognized as one of the potential alternative renewable energy fuels that can be easily available in a wide range in every part of the world. This paper reviews biodiesel’s prospect and focuses on the different fuel properties (physicochemical) of 100 biodiesels from first-, second- and third-generation followed by the evaluation of CI engine characteristics. It has been observed that the fuel properties of first-, second- and third-generation biodiesel are compatible with the ASTM standards. The present paper discussed the potential of various generations of biodiesel feedstocks from production perspectives. This paper also examined many aspects of these feedstocks which include different biodiesel feedstock sources, biodiesel conversion technology, and second-generation biodiesel performance and emission characteristics. Most of the studies showed that biodiesel derived from plant feedstock is costly than diesel. Thus, more influence is to be given to non-edible sources. However, the engine characteristics are shown promising behavior with biodiesel and a slight increase in NOX is also reported on using various biodiesel.

Conventional fuels are depleting rapidly with growing industrial evolution and growing population. The massive use of conventional fuels releases harmful emissions into the atmosphere which is the main cause of global warming. Thus, there rises a huge concern about developing sustainable and renewable fuels which can meet the growing energy demand with less harm to the environment. In the past few decades, various alternative fuels like alcohol, biodiesel, and hydrogen have been found favorable green fuels for internal combustion engines. Methanol is one of these alternative fuels which has emerged as a potential fuel. It can be obtained from fossil fuels as well as from biomass. It can be used in pure form as well as a blend component in IC engines. The utilization of methanol and its blends in IC engines significantly increases engine performance and reduces emissions. This chapter describes different aspects of using methanol as a fuel for both compression ignition (CI) and spark ignition (SI) engines. The chapter focuses on the advantages and disadvantages of using methanol as a fuel, physical and chemical fuel properties of methanol and its comparison with other fuels, and engine performance and emissions characteristics of engines fueled with methanol and its various blends.

Fast-growing population and transportation sectors have created a need to adopt a socio-economical way to produce and utilize the novel alternative fuel as an energy source all across the world. In the search for new alternative fuel, Biodiesel was found to be a reliable, and a clean fuel, having less tailpipe emission which can improve engine performance and lower the tailpipe emission while reducing the dependency on diesel. In this review, the third-generation feedstock, i.e., Algae has been selected and studied for biodiesel production. Algae has a high oil yield, carbon neutral, and booming nature. The main objective of this research work is the study of biodiesel production and its application on Diesel engine with and without nanoparticles additives. To understand critical importance of production, performance and emission aspects, a comparative study was performed. Analysis of algae as a biofuel from various research work showed that optimum concentration of additives in biodiesel blend can improve the engine performance, such as, BSFC and BTE, and further reduce the tailpipe emission especially NOX. This study reveals performance analysis of Algae as a biofuel and various advantages of using nano additives in biodiesel blends. We believe that this study will help to address the crucial research gap on biodiesel blends and nanoparticles as fuel in compression ignition engine.

Charging the electric vehicles through the use of solar PV systems is a major hurdle in today's era. In the present work, a system is designed for charging Electric bikes at workplaces like schools, colleges, offices, etc. To ensure a reliable charging system, a standalone solar PV system with a battery bank based energy storage unit is employed. It can be seen from the present work that the electric bike at different voltage configurations i.e., 12 V, 24 V, and 36 V, can be charged efficiently. The irradiance level is varied in a way to show a real-life effect that occurs during a summer day. To depict this, irradiance level is assumed to rises from 300 W/m2 to 1000 W/m2 and decline again to 300 W/m2 during the process. The DC bus voltage is successfully maintained constant at a level of 48 V in all three cases. The contribution of the study is the application of a robust solar PV based off-grid design for charging electric bike at the workplaces.

Electric vehicle (EV) are the future of the automobile industry in terms of reducing the greenhouse gas emissions, air pollution and the better life comfort level all over the world. This paper compares the results obtained by various authors in terms of life cycle assessment (LCA) of EV and conventional vehicles powered by fossil fuels, and the life cycle cost (LCC) analysis of the both types of vehicles, as every new technology comes with an additional cost which need to be feasible with respect to the present trends. And also discuss some of the software used for both type of LCA and LCC analysis. The finding of review concludes that with the adoption of EV there is a reduction in greenhouse gas emissions (GHG) but there is an increase in the human toxicity level due to the larger use of metals, chemicals and energy for the production of powertrain, and high voltage batteries. And in terms of cost it has flexible pricing as there is uncertainty in pricing of future gasoline and electricity mix, higher initial cost at the time of purchasing due to higher pricing of battery.

Gas burner plays a crucial role in any combustion systems. Thermal efficiency of conventional Liquefied petroleum gas (LPG) stove burner is not optimal. To recover the energy loss from a burner, a novel flame shield was developed based on heat conservation phenomenon for enhancing efficiency and producing less emission pollutant, which used for domestic and small-scale processing industries. Under the present study, an attempt has been made to investigate the efficiency, heat conservation, and emission products of LPG cooking stove for without and with flame shield method. The experimental test has been carried out based on the guideline of IS 4246:2002. Thermal efficiency was found of a conventional burner without flame shield is 66.27%. With usage of a flame shield, the maximum efficiency of 74.07% was found. Moreover, the maximum temperature gain and heat generation are increased by 2.1% and 3.0%, respectively. During the emission test, the CO2 increases from 0.9% to 3.8%, and NOx & HC are found less than without flame shield burner. The present study results indicate the better economic and environmental compatibility, to use the conventional gas stove burner with flame shield.

The national biofuel policy of the Indian government support to put a great emphasis on the synthesis of biodiesel from the nonedible feedstock. A potential option in this regard is Neem oil which is found in abundance in India (~1,00,000 tonnes). The major hindrance to the commercialization of biodiesel is its shelf life due to poor oxidation and stability characteristics. The current work investigates the oxidation stability of Neem biodiesel as per EU standard (EN14214) using the Rancimat apparatus. The oxidation stability of 12.3 hours without doping any chemical antioxidant in the synthesized Neem biodiesel makes it highly suitable for commercial acceptance. The impact of pyrogallol (PY) antioxidant was also investigated on the shelf life of Neem biodiesel build on response surface methodology (RSM) in accordance with Box-Behnken Design (BBD). Moreover, the execution and excretion characteristic of the Neem biodiesel blends: B15, B25, B35, and B45 are investigated on direct injection automotive compression ignition engine. Based on this broad experimental investigation B15 blend can be used as a fuel to power the existing automotive compression ignition engine with no compromise in the execution and excretion characteristics of the engine. From the analysis of the data of life-cycle assessment of the Neem biodiesel, it was found that it possesses the global warming potential of 45.72gCO2-eq Functional Unit−1 which is six times lesser than mineral diesel. Moreover, the Neem plantation has a carbon dioxide isolation potential of around 10 t ha−1 year −1. All these factors make the Neem Biodiesel highly suitable for blending with mineral diesel to power the existing compression ignition engines.

Modern-day technology aims for luxury and comfort in human life by advancement in technology. The revolutionary technological achievement has dramatically enhanced the living standards of a man. Furthermore, the construction industry is one of the largest exploiters of both renewable and non-renewable resources and promotes the use of such technologies strategically for their benefits. However, the implication of these technologies which calls for the use of supplemental technologies, promoting one another that results in increasing energy demand with limited available resources, causing a demand- supply gap resulting into a pressure that leads to stock market graph crashing and economic crisis. Urbanization, due to the growing population takes in more green patches and farmlands causing deforestation and degradation to the biosphere, further causing an increase in disasters and health hazards as a demerit. Hence with urban sprawling and scarcity of open green recreational areas, vegetated green roof has been one effective economic solution. This paper reviews the efforts of various research and review articles, government reports and experiments that emphasis on energy conservation and sustainable environment. The paper starts by describing various components and types of green roofs, and their uses. Thermal insulation, effects of shading and cooling, heat flux and evapotranspiration, reduction of carbon emissions, water savings and, microclimatic conditions are the focus group. As per previous studies, the heat flow in buildings can be reduced by 74%. Green roofs also aide in keeping the building warm during winters while retaining rainwater during the rainfall season also. It also discusses the life cycle assessment as a methodological principle and framework, and its limitations for the analysis of green roof and its passive architecture features.

A burner of the cooking stove using liquefied petroleum gas (LPG) as fuel is finding vast application in domestic as well as the industry. A huge consumption has been recorded of LPG, especially in India, and other countries too. The developed conventional gas stove has inefficient performance-wise and needs to be improving by using different techniques. In this paper, an attempt has been made to investigate the different thermodynamic parameters viz., velocity, pressure and temperature using commercial available Ansys CFX code for evaluation of performance for a conventional burner and flame shield burner. The flame shield was developed based on the principle of conservation of heat at the vicinity of burner i.e. minimizing the heat loss. The qualitative validation of flame was found fair in between experimental and numerical results. The results of temperature have been observed of 1745 K and 1910 K for a conventional burner and flame shield burner, respectively. Moreover, the flame velocity of the flame shield burner is obtained more of 0.54 m/s compared to a conventional burner of 0.10 m/s. The overall results lead to append the flame shield for enhancing the performance of conventional cooking gas and save fuel to make better economic viability.

Due to the lower productivity of solar still, researchers from all around the world are continually ensuing to improve distillate output. Hence, there are lots of opportunities and scope of research work on the solar still. Solar desalination is the process of purification saline water to get fresh potable water using direct solar energy. Seawater is available in abundance but the process of desalinating the seawater is very expensive due to enormous energy requirements. Over the years direct solar energy is used as one of the cheapest desalination methods to drive the desalination systems which has no environmental impact also. The solar-based desalination system is referred to as solar still. The basin water depth is inversely proportional to the productivity of potable water. The difference between saline water temperature and glass temperature controls the evaporation rate. The water surface area is directly proportional to the distillation rate. The water surface area has been increased by submerging the wicks in the water, the use of porous materials, fins, sponge, etc. Instead of a single flat horizontal collector, the cascade style still gives more useful results in terms of desalination. The use of phase change materials helped further in the overall increase in the distillation rate. In the present short review paper research works done in this decade have been considered and four primary methods like the effect of the finned absorber plate, cotton wick, and phase change material and nanoparticles have been discussed. It will help future research in the area of solar still to provide an economically viable solution for sustainable potable water.

Small hydropower is a mature and cost-competitive energy technology. The maintenance cost of small hydropower plant is one of the critical factors to analyze the net benefits of the plant. In this study, an attempt has been made to develop the maintenance cost correlation for the high head run of river small hydropower plants based on capacity and head as cost influencing parameters by linear regression approach in MATLAB. The results revealed that the maximum deviation is ± 12.60%, the maximum average deviation cost has been obtained for turbine which is ± 11.35% and minimum average deviation cost is for thrust bearing i.e. ± 3.5%. Overall average deviation in maintenance cost of all the studied components is ± 7.35%, which shows that the developed correlations are in good agreement. Therefore, these correlations can be used to determine the maintenance cost of high head run of river small hydropower projects.

The electrical efficiency of a solar photovoltaic panel, is low. Sunlight is the essential input to generate electricity, but they put an adverse effect on its performance due to the rise in temperature at the backside of the panel. The rise in temperature is directly related to the sunlight whose energy is converted into heat and may put a negative effect on the electrical parameters and the life span of the cell. The implementation of cooling techniques will result in reducing the excess heat generated and to reduce overall cell temperature. Most of the research has two paths, one is to enhance the efficiency of the solar PV cell and another to ensure a longer life span at the same time. This paper explains the cooling methods i.e. heat sink, heat pipe, PCM material based, microchannel, thermoelectric (Peltier). Different feature and capability of cooling techniques are explained, to provide valuable information and direction for the researcher for future research, to enhance or upgrade the cooling techniques. The finding of review reveals that water-based microchannel gave efficient cooling besides hot water for various application and combination with PCM make it more efficient in both electrical and thermal aspects.

India is a nation with a diverse economy that requires tremendous resources to completely meet the desires of its compatriots in various sectors. In terms of energy resources and requirements, coal-based power plants can fulfill the bulk of these electricity needs. India is very reliant on coal, which is used in power plants as a primary energy source. However, the usage of coal energy at a higher level continuously pollutes the atmosphere. The Indian power market alone accounts for half of the country’s CO2 emissions, which implies that significant action is needed to contain environmental pollution. Carbon Capture and Storage (CCS) is a bridging technique and feasible alternative for the carbon fired plant processing of CO2. However, the application of CCS in coal-fired power stations is still uncommon in the nation. At the UNFCCC Paris Summit, India committed to reduce its carbon emission intensity by approximately 30–33% by 2030. In this work, several CCS systems, possible CO2 origins, and emission levels in India are discussed. Various advanced methods for CO2 capture and separation are also highlighted. Furthermore, the current work discusses CCS situations and the applications of CCS in India along with its manifold challenges.

In today’s world, the main focus is to reduce the dependency on fossil fuels for fulfilling the increasing energy demand. Burning of fossil fuels leads to emission of greenhouse gases that pollute the environment. Renewable energy sources such as wind energy, solar energy, etc. are sources of clean energy. Solar energy is present abundantly in most parts of the world and it can be utilized as prime source to meet the energy demand. Drying of various products such as fruits, crops, etc. requires energy in form of heat for removal of the moisture content to a certain limit so that the product can be preserved for longer period of time. Traditionally open sun drying is used for drying purpose but it has various shortcomings such as poor quality of dried product, large open space requirement, longer drying time, etc. To overcome these issues of open sun drying, a large variety of solar greenhouse dryer has been introduced. The main objective of this paper is to analyze the recent developments in greenhouse dryer keeping in mind the performance, economic and environmental aspects. The study in this review paper reveals the various advancements and their impact on the performance of greenhouse dryer. This review paper will help in addressing research gaps on critical areas of greenhouse dryer.
