Current trends and prospects of tidal energy technology

Abstract

Generation of energy across the world is today reliant majorly on fossil fuels. The burning of these fuels is growing in line with the increase in the demand for energy globally. Consequently, climate change, air contamination, and energy security issues are rising as well. An efficient alternative to this grave hazard is the speedy substitution of fossil fuel-based carbon energy sources with the shift to clean sources of renewable energy that cause zero emissions. This needs to happen in conjunction with the continuing increase in the overall consumption of energy worldwide. Many resources of renewable energy are available. These include thermal, solar photovoltaic, biomass and wind, tidal energy, hydropower, and geothermal. Notably, tidal energy exhibits great potential with regard to its dependability, superior energy density, certainty, and durability. The energy mined from the tides on the basis of steady and anticipated vertical movements of the water, causing tidal currents, could be converted into kinetic energy to produce electricity. Tidal barrages could channel mechanical energy, while tidewater river turbines can seize the energy from tidal currents. This study discusses the present trends, ecological effects, and the prospects for technology related to tidal energy.

Quantitative analysis of renewable energy system structure based on the weather condition in Cambridge, London, and Oxford

“…Scientific advancement has increased the quantity of energy produced by the ocean. The 2019 growth rate was 13%, which was much greater than the rate of increase in the previous three years [11]. It is a generally steady and consistent source of energy, with little influence from climate, hydrology, or other natural causes.…”

Adapting to a changing climate in the management of coastal zones

“…Human activity in inland river basins also affects sediment supply. The construction of dams, channels and water reservoirs reduces the amount of sediment reaching the coast in many areas, 18 exacerbating coastal 18. For example, nearly half of the world's major rivers have experienced a significant reduction in sediment influx (Wong et al, 2014 [5] ).…”

A Review of SPH Techniques for Hydrodynamic Simulations of Ocean Energy Devices

“…Since the capture and exploitation of ocean energy started to receive attention by the scientific and industrial communities [3], the technologies for harnessing ocean energy have been investigated and developed significantly to meet the energy market, which considerably fosters the invention of diverse Ocean Energy Devices (OEDs) ranging from small-scale isolated apparatus [4] to largescale Integrated Energy Harvesting Systems (IEHSs) [5,6]. Generally speaking, as shown in Figure 1, the classification of OEDs can be mainly categorized by their energy resource, i.e., winds (e.g., Floating Wind Turbines, FWTs) [7][8][9][10], waves (e.g., Wave Energy Converters, WECs) [11][12][13], currents (e.g., Tidal Current Turbines, TCTs) [14][15][16], and multi-resource (see e.g., [6]). As pointed out by Said and Ringwood [17], ordinary OEDs consist of four phases to converting ocean energy to electricity (see also Figure 2), namely, absorption, transmission, generation, and conditioning.…”
