Solar energy and biomass offer sustainable alternatives to meet the energy demand and reduce the environmental impact of fossil fuels. In this study, through mass and energy balances, a comparative analysis of energy, exergy, and environmental impact (LCA) was conducted on two renewable thermal sources: solar energy and coconut shell biomass, both ...

Although energy transformation is a widely discussed topic, there is a dearth of research on the role of rural communes in implementing that concept in Poland, a country where rural areas account for more than 90% of the total landmass. Most research projects are focused on larger local government units, such as cities, whereas rural communes’ role...

Magnetohydrodynamic (MHD) generators are direct energy conversion devices that transform the motion of an electrically conducting fluid into electricity through interaction with a magnetic field. Developed as an alternative to conventional turbine-generator systems, MHD generators evolved through the 20th century from large units, which are intende...

Access to energy is a major challenge in Burkina Faso, with only 22.5% of the population benefiting from electricity, particularly in rural areas. This highlights the need to develop innovative solutions to improve energy supply. The aim of this study is to explore how technological innovation can be used as a lever to overcome these energy obstacl...

With increasing efforts to lower CO2 emissions globally, the demand for carbon-based resources in industries remains on a high level, leading to new technologies being able to provide those essential carbon sources. To the best of our knowledge, we were able to show for the first time the adaption of a readily available gasifier for the gasificatio...

The momentum of the Fourth Industrial Revolution is driving increased demand for certain specific metals. These include copper, silver, gold, and platinum group metals (PGMs), which have important applications in renewable energies, green hydrogen, and electronic products. However, the continuous extraction of these metals is leading to a rapid dec...

Due to the massive expansion of renewable energy-based production capacity, the benefits and drawbacks of wind turbines, ground-mounted photovoltaic (PV) and biogas plants are currently being discussed in Germany and elsewhere. The expansion of renewable energy-based plants is competing with other uses for land area. In addition to area-specific en...

This research aims at proposing an alternative to improve the efficiency of electric vehicles (EVs) and reduce greenhouse gas (GHG) emissions in the context of electric mobility. A photovoltaic and wind hybrid energy system was installed in a Chok S2 electric vehicle. In addition, a charge equalization system was included to balance and maximize th...

The development of solar energy at a regional scale necessitates a thorough understanding of available resources. Cuba, facing prolonged economic, environmental, and energy crises, urgently needs to enhance its sustainability through solar energy. Although solar resource mapping is widespread, Cuba lacks extensive field measurements, often relying ...

This article presents a detailed analysis of the energy availability of a 15 kW hybrid wind–solar photovoltaic microplant, designed to supply the electricity demand of the power-to-gas (PtG) pilot plant located at the University of La Guajira, Colombia. The study addresses the lack of specific data on the energy availability curve, which is essenti...
