This compilation first describes a system wherein a high-nuclear high-temperature reactor supplies constant power to a thermal energy storage unit of molten lithium chloride salt, which provides the required thermal energy for a closed energy conversion system. Next, a compact power generation-storage system is constructed using a direct current-alternating current inverter, spherical Si solar cells, and a lithium-ion battery integrated into a single module. The authors discuss how, since a number of different countries' electric power utilities are adding capacity, there is an opportunity to introduce a new, longer-lasting design for a wind turbine system. A method to reduce the consumption of high-pressure steam and cool fluid in the ethanol process is presented, as well as a plan to reduce the emission of environmental pollutants from the H-501 furnace in the maleic anhydride process. Energy optimization is carried out for the condensation stabilization component of Ilam gas refinery. The closing study focuses on techniques such as the adjacent tree-bounded hop algorithm that may be used to reduce the energy consumption of wireless sensor networks, whether static or dynamic.

Volume 33 begins with a focus on gas hydrates, also known as methane hydrates, which are formed due to high hydraulic pressures present under the cold seabed over long periods of time. Following this, an exploratory method using semi-structured interviews was undertaken to investigate the barriers and drivers for implementing energy efficiency measures in South Africa's cement finishing mill. To address the large energy consumption of microalgae dewatering and to increase revenues from microalgae, a novel process for the prior sustainable extraction of carotenoids from wet microalgae biomass is proposed. The authors describe the evolution of smart grids in some developing countries, highlighting the challenges and trends for the next years. For this purpose, reference cases corresponding to different developing countries of Africa and America are used. Additionally, the basics of high efficiency cogeneration and the mathematical model used to calculate the amount of electricity in cogeneration are discussed. In one study, the impedance of the diffusion and reaction processes in an electrochemical cell is modelled by means of transmission line equivalent electric circuits. To discuss the applications of common techniques to control the efficiency and costs of underground ventilation, detailed information on current practices is collected through discussions with miners to identify relevant problems. The authors go on to explore barriers and enablers which impact the durability of solar street lighting systems in rural India to create a renewable energy eco-system in rural poor communities. Later, it is proposed that statistical control charts can assist in controlling energy consumption in universities, and the rate of energy consumption flow is used to diagnose high-energy consumption. The closing research is an analysis of problems found during the operation of the biogas power system at Baiturrahman boarding school, West Java, Indonesia, and recommendations to enhance the system performance are provided.

Advances in Energy Research. Volume 32 opens with a comprehensive review of technologies for the reutilisation of waste cryogenic energy from the liquefied natural gas regasification process at terminals and on marine vessels. The authors discuss the primary renewable energy source in Cuba; biomass. Although sugarcane biomass has the most significant energy potential, some other biomass energy sources are also relevant at the local level and are convenient from an environmental standpoint. Invisibility cloaks of various types have been researched extensively in recent years with one of the first being the electrostatic cloak, so-named because it effectively screens an internal volume from, and offers no disturbance to, an external static electric field. As such, this compilation explores this phenomenon and whether the cloaked object (or the cloak itself) could be detected by various means. The concluding study explores how, in order to reduce the consumption of oil for electricity generation by 20% in Cuba, the country should build a total of 13 wind farms with a capacity of 633 MW.

In the past, fossil fuels have been considered a reliable source of energy by many countries. Despite the current measures to reduce the use of fossil fuels for electricity generation, the use of this type of energy source will continue for the foreseeable future. Advances in Energy Research. Volume 31 examines how, if this situation does not change in the future, then all types of fossil fuels, particularly oil, will be exhausted before the end of the current century. The use of microholes may potentially enhance the applications of fossil fuels in various energy fields, especially in thermal power plants. Therefore, the morphology variation of micropunch and microhole during the punching with WC/Co micropunches is investigated in this compilation through scanning electron microscopy, energy dispersive spectrometer and confocal laser studies. Following this, the authors provide a review on experimental and modeling studies performed with direct fuel cells, starting with the fundamentals and main drawbacks of these systems, followed by an exhaustive review on the different studies performed regarding the effects of operating conditions and design parameters. In the penultimate chapter, a new method for determining the cohesion potential energy in solids is described, and fundamental factors such as internal energy, entropy, temperature and time are examined, in particular the connection of entropy and time to potential energy. The method concerns molecular solids and rests upon measurable thermodynamic quantities: heat of sublimation, heat capacity, and entropy as derived from the latter. The closing chapter provides an overview of three methods (retarded osmosis method, forward osmosis-electrokinetic method, and diffusio-osmotic method) for sustainable power generation from the salinity gradient energy by using osmosis-based processes.
