THE HYDROTHERMAL VENT RENEWABLE ENERGY IN THE DEEP OF THE SEA IN THE UNITED KINGDOM

2024-09-25T21:37:08+08:00

In just forty years, numerous hydrothermal vent fields have been identified, spread across tectonic plate boundaries on the ocean floor. The substantial biomass of vent invertebrates, which can reach up to tens of kilograms per square meter, has sparked interest in their role in contributing to the deep-sea organic carbon pool, which is otherwise limited in resources. However, the rate at which organic carbon is produced through chemosynthesis at these deep-sea vents varies widely and remains inadequately understood. Despite advancements in molecular techniques and in situ sensors, the factors determining how vent communities utilize available chemical energy resources are still largely unclear. The intent of this research is to examine hydrothermal vents as an alternative energy and a new resource of renewable energy. Hydrothermal vent energy is very worthy of being a new renewable energy resource. Although the hydrothermal vent is hard to find since we know that the position of these resources is much deeper, We know that we can make these new resources useful for reducing emissions. Hydrothermal vents are deep in the offshore. They are formed from the conserved remains of animals and plants. As hydrothermal vents are buried deep underground, geological knowledge and advanced equipment are required to reach them. This research showed the renewable energy in the deep sea is hard to find but worthy. However, the hydrothermal vent is a new resource in the deep of the sea and can be useful in reducing emissions.

OPTIMIZATION OF SUSTAINABLE HYBRID MICROGRID FOR RURAL ELECTRIFICATION: TECHNO-ECONOMIC AND ENVIRONMENTAL PERSPECTIVES

2024-10-01T18:39:01+08:00

The energy crisis problem in rural communities of developing countries is fast becoming a contemporary challenge to advancing global socioeconomic systems. Finding sustainable solutions for improving the energy supply to rural communities is significant. Thus, this paper presents the optimization of a hybrid microgrid with integrated energy components of Photovoltaic (PV) systems, Diesel Generators (DG) and Battery Energy Storage Systems (BESS). These energy components were configured and techno-economically investigated in three different scenarios of PV/BESS, PV/DG/BESS and DG only for load power supply to an isolated unelectrified Nigerian community. To the relevant decision factors, the chosen objective functions of the Deficit Power Supply Probability (DPSP), the Cost of Energy (COE), and the Net Present Cost (NPC) were minimized. In addition, new intelligent multi-objective computational methods such as Ant Colony Optimisation (ACO), Flower Pollination Algorithm (FPA), Genetic Algorithm (GA), and Particle Swarm Optimisation (PSO) were applied to handle the optimization problems. Based on the input techno-economic and meteorological data applied for the simulations, the best solution for the optimal sizing configuration was obtained by the PV/BESS through the FPA with the NPC value of $95,432.02, COE of 0.165 $/kWh and zero GHG emissions. A value of 1.72% DPSP was also obtained for the PV/BESS hybrid configuration. This indicates that unlike PV/DG/BESS and DG alone, PV/BESS is techno-economically viable for the electrification of the case study community.

CHALLENGES AND PROSPECTS OF RENEWABLE ENERGY PENETRATION AND ENERGY STORAGE TECHNOLOGIES IN INDONESIA: A REVIEW

2025-02-03T08:37:05+08:00

Indonesia has significant renewable energy potential, but it is underutilized due to technical, economic, and integration constraints. This study looks at the challenges to solar and wind energy adoption and assesses the role of energy storage technologies in overcoming them. Photovoltaic (PV) and wind systems have fluctuation, grid instability, and reactive power control issues, whilst geothermal and hydro sources, while more reliable, still require additional grid services. This paper summarizes the technical and grid integration challenges of PV systems, emphasizing issues such as harmonic distortion, voltage instability, and high upfront costs. Potential options for energy storage include lithium-ion batteries, pumped hydropower, and compressed air. Each technology's distinguishing features, such as energy density, cost, and operating restrictions, are thoroughly evaluated. Despite their promise, hefty investment costs and limited deployment prevent widespread adoption. This article provides techniques for increasing renewable energy integration, such as hybrid power systems, better grid management, and sophisticated energy storage options. Future research should concentrate on microgrid optimization, cost-benefit modeling, and case study comparisons to help drive policy and infrastructure development. This comprehensive research emphasizes the importance of innovative ideas to help Indonesia achieve its energy transition and sustainable development goals.
