Wave Energy
This document discusses wave energy as a renewable source of energy. It explains that wind energy transfers to ocean waves, and wave energy machines like turbines and buoys can capture this energy from waves and tides to generate pollution-free electricity. While wave energy technology is still developing, it is estimated that fully utilizing wave energy could satisfy around 40% of the world's total energy needs. The main ways to capture wave power are surface devices, underwater devices, and reservoirs. The document also describes different types of wave energy converters including attenuators, point absorbers, submerged pressure differential devices, overtopping devices, and oscillating wave surge converters.
Oyster wave energy converter
Introduction:
With a growing focus on renewable energy, interest in the wave energy has also been expanding. Ocean waves are a huge, largely untapped energy resource, and the potential for extracting energy from waves is considerable. The paper describing one of the recently invented and developing wave energy converter, namely Oyster Wave energy converter.
In response to the need to find additional sources of renewable energy to combat climate change, ensure domestic energy security and develop new industries a large community of wave energy researchers and commercial device developers has arisen in recent years, pursuing a considerable number of different technologies for the conversion of wave energy. A company named, Aquamarine Power Ltd. had invented its new model of wave energy converter and named it as Oyster.
Construction:
Oyster harnesses the energy of near-shore ocean waves. It was designed to operate in water 10 to 12 meters deep. The Oyster is made up of a Power Connector Frame (PCF) and a Power Capture Unit (PCU) or oscillator. The PCF is bolted to the seabed by 1-by-4 meter concrete piles that are drilled 14 metres deep into the seabed. The PCF requires careful and accurate positioning and leveling to compensate for the uneven, rocky seabed.The PCU is a 200-ton, 18-by-12-by-4 metre buoyant flap that is hinged to the PCF. In order to lower the PCU into the water to hinge it to the PCF, 120 tons of seawater must be pumped into ballast tanks within the PCU to provide sufficient negative buoyancy to aid its descent into the water. The PCU is almost entirely submerged underwater; only 2 metres of the device poke above the water. It has two hydraulic pistons connected by two sub-pipes streched upto the shore.
working:
With the movement of the waves, The PCU or oscillator sways back and forth, and this movement of the flap drives two hydraulic pistons that pump high-pressured water through sub-sea pipeline to an onshore hydro-electric water turbine. The turbine then drives an electrical generator, which converts the wave energy into electricity. The water exhausted from the turbine returned back to the sea.

The document summarizes wave energy and its potential as a renewable energy source. It discusses how waves are generated by wind, the history of wave energy technology development, and the main types of wave energy conversion systems including attenuators, point absorbers, oscillating water columns, and overtopping devices. It provides examples of current wave energy projects in locations like Scotland, Portugal, and Australia. It also discusses Egypt's potential for wave energy and the challenges still facing the widespread commercialization of wave power, such as high costs, environmental impacts, and ensuring device reliability in harsh ocean conditions.
Wave power
Wave power is a renewable energy source that can be harnessed using three main types of collectors: buoyant moored devices that float on the surface or below, hinged contour devices that follow wave motion at joints to create power, and oscillating water columns where wave motion acts like a piston to pump air and drive a turbine. Future prospects for wave power include the first US license granted to a company for a wave project and an agreement for a two megawatt wave energy project off California's coast.

Recent trends in wave energy using oyster device
Aquamarine Power has developed a wave energy converter called Oyster, which is the world's largest at 40MW capacity. It was installed at EMEC in Scotland. Previously the largest was only 2.4MW in the UK. Oyster uses the motion of a hinged flap from wave movement to drive hydraulic pistons, which pressurize water to turn a turbine and generator on shore to produce electricity in an efficient hydro-electric process. Oyster is estimated to operate efficiently for 15 years and provide reliable, eco-friendly energy from the ocean.
Under water wind mills
This document presents a seminar on underwater windmills. It describes underwater windmills as devices that extract power from tides in a similar way that wind turbines extract power from wind. The main parts of underwater windmills are described as turbines, a gearbox, generator, cables, and support structure. Tidal currents cause the turbine rotor to spin and turn a generator to produce electricity via transmission cables. Examples of existing and planned tidal power installations are provided from locations around the world. Advantages include being a renewable source with low costs and maintenance, while disadvantages include high initial costs and difficulty of installation.
Tidal energy
Tidal energy harnesses the power of tides by converting the energy from tidal movements into electricity. Tides are created by the gravitational pull of the moon and sun. Tidal energy has the advantage over other renewable sources in that the tides are entirely predictable. There are three main methods of tidal power generation - tidal barrages, tidal streams, and tidal mills. Tidal barrages capture energy by holding water back with barriers and releasing it through turbines. Tidal stream turbines operate similar to wind turbines but are designed to withstand stronger forces from water. India has an estimated potential of 8,000 MW of power from tidal sources along its coastline.

Ocean energy harnesses energy from waves, tides, salinity gradients, and ocean thermal differences and has the potential to be a large renewable energy source. It accounts for around 0.1% of global energy production currently but could be developed further. There are two main categories - thermal energy from the sun's heat in surface waters and mechanical energy from tides and waves. Examples of technologies under development include wave farms using turbines on shorelines or floating devices offshore, as well as tidal barrages and tidal stream generators. While ocean energy has advantages of predictability, it also faces challenges of high costs and environmental impacts that need addressing for fuller commercial development.

Offshore Wind – A New Market for Land-Based Wind Developers and Their Supply ...Energy Network marcus evans
Jim Lanard, Offshore Wind Development Coalition - Keynote Speaker at the marcus evans Wind Power Summit 20123 held in Dallas, TX February 25-26, 2013, delivered his presentation entitled Offshore Wind – A New Market for Land-Based Wind Developers and Their Supply ChainEE526 Final Report Group 4
This proposal suggests installing a tidal and wave power plant off the coast of Southern California to supply electricity to 100,000 customers. The plant would use Deep Green tidal stream generators and WaveNet wave energy converters. 30 Deep Green DG-12 devices, rated at 500 kW each, would generate 15 MW from tidal energy. 141 WaveNet Series 24 devices, rated at 750 kW each, would harness wave power to generate 100 MW. The combined plant is expected to have a total installed capacity of 115 MW.
Oceans as a non conventional source of energy
This document discusses harnessing energy from ocean sources like tides and waves. Tidal power uses the rise and fall of tides to generate electricity through tidal barrages and turbines. The gravitational pull of the moon and sun cause tides. Tidal power sites currently exist in France and Canada. Wave power captures energy directly from ocean surface waves and pressure fluctuations below. Devices like nodding ducks and oscillating wave surge converters can be used to generate electricity from wave motion. India has potential tidal power sites along its coasts and should invest more in research and development of non-conventional energy sources to reduce dependence on imports and greenhouse gas emissions.
Wave Power
Sea waves have high energy densities, the highest among renewable energy sources with the natural seasonal variability of wave energy following the electricity demand in temperate climates securing energy supplies in remote regions.
Tidal energy 2
Tidal energy harnesses the movement of tides to generate electricity. Early tidal power plants used barrages to contain water after high tide, releasing it through turbines to power generators. Newer tidal stream technologies place turbines directly in tidal currents, allowing energy production on both ebbing and surging tides. While tidal energy has the advantages of predictability and zero emissions, development has been limited by high costs and potential environmental impacts.

The document summarizes energy research at the University of Alaska Fairbanks' Alaska Center for Energy and Power (ACEP). ACEP's mission is to develop cost-effective energy solutions for Alaska through applied research, technology testing, energy analysis, training, and commercializing innovation. Key areas of research include solar, hydrokinetic, and battery technologies as well as power systems integration. ACEP also disseminates information and provides training programs like the Arctic Remote Energy Networks Academy. One project discussed is the proposed Yakutat Wave Energy Project which would use wave energy to power the remote city of Yakutat currently reliant on diesel.
OTEC
Ocean thermal energy conversion (OTEC) uses the temperature difference between warm surface waters and cold deep waters to vaporize and condense a working fluid like ammonia to drive a turbine and generate electricity. The technology was studied for development in Fiji in the 1980s and 1990s with the goal of installing a 10 MW demonstration plant, but no projects were ultimately built. OTEC provides baseload renewable power but challenges include the high costs associated with long cold water pipes needed to bring deep seawater to land-based plants. Floating plants could reduce pipe costs but have expenses related to maintenance and mooring. More research is still needed to help OTEC become commercially viable.
