Solid-State Hydrogen Storage for a Decarbonized Society

Humanity is confronted with one of the most significant challenges in its history. The excessive use of fossil fuel energy sources is causing extreme climate change, which threatens our way of life and poses huge social and technological problems. It is imperative to look for alternate energy sources that can replace environmentally destructive fossil fuels. In this scenario, hydrogen is seen as a potential energy vector capable of enabling the better and synergic exploitation of renewable energy sources. A brief review of the use of hydrogen as a tool for decarbonizing our society is given in this work. Special emphasis is placed on the possibility of storing hydrogen in solid-state form (in hydride species), on the potential fields of application of solid-state hydrogen storage, and on the technological challenges solid-state hydrogen storage faces. A potential approach to reduce the carbon footprint of hydrogen storage materials is presented in the concluding section of this paper.

Assessing cooling energy of insulated building built in tropical country

Global warming is a huge issue and has become a global concern lately. The global warming issue is gaining more attention on reducing fossil energy since fossil energy has significantly exacerbated global warming. Since housing sectors are consuming significant fossil fuel energy, reducing housing energy consumption is necessary. One option discussed in this paper is to reduce the load on the air conditioner (AC) by applying insulation to the building. Reducing the AC energy will reduce the total energy consumption in the buildings. Building practice in a mild climate has shown that good insulation can reduce heating or cooling energy in the building. But using insulation in housing is not a common practice in Indonesia’s construction sectors. Simulating the use of insulation in housing will show how much energy reduction will be obtained, especially for air conditioning energy. The analysis in this study found that thermal comfort is related to air temperature and relative humidity in the room. This article will study the reliability of using insulation in buildings to reduce energy consumption and provide thermal comfort for the occupant.

LOCALIZED SUSTAINABLE AND ECOFRIENDLY ENERGY GENERATION AND DISTRIBUTION USING BLOCKCHAIN NETWORK: BANGLADESH PERSPECTIVE

Thepower industry of Bangladesh is not enough sustainable and eco friendly which is governed by anumber of centralized authorities The energy is received from various power plants and then route theenergy to substations and eventually to the consumers which is palpably inadequate to meet the farreaching demand This leads to the load shedding in many areas which is still a burning question from thesocio economic perspective of Bangladesh A significant percentage of people are still deprived ofuninterrupted energy supply and a many more are still out of the energy distribution network due to lackof resources The energy currently available in the country is mainly fossil fuel energy which is neithersustainable nor eco friendly and the centralized distribution of energy requires the transmission of energyat high voltages which has a lower efficiency and adds to the wastage of energy Another core problem isunauthorized connection of energy and intentional faulty meter reading submission by operators whicheventually leads to a momentous loss of revenue, and this creates a sense of skepticism among the massusers on the local authorities responsible for proper energy management From the economic perspective,it is imperative to create a sustainable sector of investment for mass people due to the current fragile stateof stock market and banking system Addressing these issues is obligatory to maintain the economicgrowth of Bangladesh as well as to elevate the lifestyle of mass people The aim of our project is to attainthese milestones by creating a localized energy generation, storage, transmission and distribution systemusing blockchain which exhibits some genuine concern on pertinent areas and solution of the issues.

ICT development, governance quality and the environmental performance: avoidable thresholds from the lower and lower-middle-income countries

PurposeThis paper aims to study the relationship between information and communication technology (ICT) readiness, use, and intensity and environmental sustainability factors in the lower and middle lower-income countries from 2012 to 2018.Design/methodology/approachICT readiness, use and intensity are measured with the impact of ICT on access to basic services, phone penetration and Internet penetration, while CO2 emissions per capita, fossil fuel energy consumption and methane emissions are used as indicators for air pollution. To achieve this goal, a two-step generalized method of moments (GMM) estimation was performed which thresholds are computed contingent on the validity of tested hypotheses.FindingsThe results demonstrate that increasing ICT readiness, use and intensity in lower and lower-middle-income countries enhance environmental sustainability by decreasing CO2 emissions and energy consumption.Research limitations/implicationsOne of the limitations of this study is that the conclusions and policy recommendations do not take into account the specificities of each country. Indeed there are some differences in the growth pattern of ICT in the lower and middle-lower-income countries. Taken together, the authors conclude that increasing ICT has a positive net effect on CO2 and methane emissions per capita, while increasing the impact of ICT access in basic services has a net negative effect on CO2 fossil fuel energy consumption and methane emissions.Practical implicationsThe world needs immediate emissions reduction to avoid the long-term danger of climate change. Second, government authorities should give additional efforts in the more pollutant sector such as transport and industry to monitor their energy consumption.Originality/valueTo explore this issue further, the negative net effects suggest that ICT needs to be further developed beyond the determined thresholds, to attain the required negative net effect on fossil fuel energy consumption.

Energy Saving and Renewable Energy production at University of Kashan, Kashan, Iran

University of Kashan was founded in 1974 and is the oldest institution of higher education in Kashan. Kashan (33° 58' 59" N / 51° 25' 56" E) climate is classified as a hot and dry by the Köppen-Geiger system. This climate causes a large amount of energy consumption for University at springs and summers. On the other hand, it means that sun is shining strongly for more than 6 months and University of Kashan has been working on some solutions to use solar energy and decrease dependency on the old fossil-fuel energy system. The current paper studies some of the main activities of University of Kashan on Energy Saving and Renewable Energy Production programs such as CCHP plant (The first Combined Cool, Heat, and Power plant in Iran), using solar panels and energy-efficient appliances.

Harnessing Maximum Power from PV Module using DC-DC Converter

Solar energy is one of the most potent sources of energy. In the wake of depleting fossil fuel energy sources and growing environmental concerns, world is in a relentless drive towards utilizing natural resources like sun efficiently. The aim of the project is to make the solar module work in MPPT mode (Maximum Power Point Tracking) Mode. At this condition, the system is able to extract maximum power from the module without affecting the PV module. MPPT control here is obtained using boost converter. Applying PWM with proper controlling algorithm will vary the duty ratio of the converter such that system will run in MPP mode.

An energy method for computing the use of fossil fuel energy

An energy method for computing the use of fossil fuel energy has been considered in the article. On the world market, the fuel price depends on supply and demand and involves no energy costs for fuel production. An energy analysis of economic activity was suggested by Charles Hall, an American scientist, who introduced a notion of Energy Returned on Energy Invested, as a ratio between returned and invested energy, into scientific discourse. No account has been taken of invested energy depreciation in this method. All losses are fully incorporated, when the ratio between beneficially used energy in all process flow chains from fuel deposit exploration to energy utilisation, and the considered amount of natural fuel primary energy is taken as the coefficient of beneficial primary energy use (CBPEU). When CBPEU is determined, allowance is made for all potential energy losses; the depreciation degree of energy, contained in the fuel, from its deposit to a consumer, is defined. When energy of renewable sources is utilised, a coefficient of renewable sources energy conversion, defined as the ratio between energy delivered by a power unit throughout the entire operation period, and invested energy taking into account CBPEU over the same period, will represent an objective criterion of power unit efficiency.
