Ammonia is a toxic gas and can cause tragic consequences for humans. The damage level depends on concentration and duration of exposure. The security length associated with the risk of a tank leak at the acute exposure level of 30 ppm (AEGL-1) has been computed. Two tools have been combined: the CTOA criterion and the ALOHA software. The CTOA, a measure of fracture resistance against ductile crack propagation, is implemented in Abaqus software to compute the size of a breach in a tank submitted to internal pressure [...]

This article outlines an innovative approach to explore thermal energy extraction for power generation or industrial hot water applications. Unlike traditional steady-state models, this approach embraces time-variant scenarios, explicitly incorporating a cyclical fluid circulation strategy to maintain a stable surface fluid temperature or power output. By introducing an increasing and decreasing stepwise rate sequence and an intermittent circulation strategy, the method aims to optimize efficiency in response to va [...]

One way to increase solar photovoltaic penetration in the grid is the management of voltage fluctuations. This is because a photovoltaic plant cannot be interconnected to the grid if it causes voltage violations. Voltage violation is where voltage exceeds the acceptable range. Often, grid operators request photovoltaic plant owners to regulate voltage sufficiently with expensive and space-consuming static Var compensators. Unfortunately, this sometimes makes the project less feasible. This paper argues that there a [...]

This initiative aims to enhance the efficiency of utility demand response (DR) operations by coordinating and integrating behind-the-meter (BTM) photovoltaic systems (PV) and energy storage (ES) using innovative machine learning software applications embedded in a distributed control architecture. The project is in the process of creating distributed energy resource (DER) learning agents and optimization engine within a hierarchical and layered distributed control architecture (DCA). These components work together [...]

Adsorption of toxic gas of CO molecules by using transition metals of X (X = Ti, V, Cr, Co, Cu, Zn)-doped boron nitride nanocage (B5N10_NC) has been studied by computational chemistry. Based on NQR analysis, X-doped on B5N10_NC has shown the lowest fluctuation in electric potential and the highest negative atomic charge, including 0.2331 (copper), 0.3112 (cobalt), 0.5883 (chromium), 0.6853 (zinc), 0.6893 (vanadium) and 0.7499 coulomb (titanium), respectively, have presented the most tendency for being the electron [...]

The paper analyses the performance of a spherical solar collector compared to the efficiency of a flat-plate solar collector, which is the type of solar collector that does not use a tracking system in collecting solar radiation for energy conversion. Spherical solar collector benefits from a constant value of the angle of incidence, which optimizes the solar radiation that strikes the absorber of the solar device and maximizes the energy collection. Besides, the spherical geometry has a larger area for equal dimen [...]

Solid lithium-ion conducting polymer electrolytes are attractive candidates for battery applications because they are flexible and less flammable, and can be easily prepared as large-sized thin films. However, the room temperature conductivity of conventional polymer electrolytes is relatively low, and detrimental lithium dendrite formation is observed at high current density. In this study, a composite polymer electrolyte of polyethylene oxide (PEO) with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and a hi [...]

The tariff policy for energy services is a fundamental issue for today's societies, especially for end users, including residential, commercial, and industrial. The main objective of this paper is to propose a statistical method to calculate, compare, and evaluate policies of this nature. To this end, firstly, it is intended to rethink an old concept on this type of policy, the principle of fairness and reasonableness, through the linkage with the perspective of human rights, specifically with the right to energy, [...]
