Workshop on Ocean Renewable Energy Application

Why Ocean Energy?

It’s always available.
Unlike other renewable power sources, ocean energy has the potential to be available all the time. There is even more energy available in the waves on the Oregon Coast in the winter, when the region uses the most energy.

It’s predictable.
Wave patterns, height and strength can be accurately predicted days in advance.

It’s reliable.
In Oregon, ocean energy will be generated close to where most of the power is consumed. This increases reliability of the transmission grid and reduces inefficiencies of transferring power from the eastern parts of the state. The entire Oregon Coast is connected to Bonneville Power Administration transmission lines, so the power can be easily moved to where it is needed.

It reduces our reliance on fossil fuels.
Adding ocean energy into the resource mix will help the state reach greenhouse gas emission targets, including carbon reductions of 10 percent by 2020 and 75 percent by 2050.

It’s clean and renewable.
The ocean is the largest, most concentrated supply of renewable energy on Earth, and has the potential to provide 10 percent of the world’s energy. Ocean energy is clean, predictable and renewable. It has no greenhouse gas emissions, produces no pollution and requires no major drilling or mining

Topics of interest for submission include, but are not limited to:

A. Wave

Wave energy technologies extract energy directly from surface waves or from pressure fluctuations below the surface. However, wave energy cannot be harnessed everywhere. Wave power-rich areas of the world include the western coasts of Scotland, northern Canada, southern Africa, and Australia as well as the northeastern and northwestern coasts of the United States. In the Pacific Northwest alone, it is feasible that wave energy could produce 40–70 kilowatts (kW) per 3.3 feet (1 meter) of western coastline.

Wave energy can be converted into electricity by offshore or onshore systems.

Oscillating Water Columns
These are partially submerged structures that house a column of air above a column of water. Waves are then funneled into the structure below the waterline, forcing the water column to rise and fall like a piston. This movement both pressurizes and depressurizes the air column, moving a bidirectional turbine with the resulting “push/pull” force.

Overtopping Device
The overtopping device generally is constructed on shore or on a levee. There is a collector that funnels waves over the top of the structure and into one of the device’s reservoirs positioned below the waterline. The water is then run back out to sea through one or more turbines. As the water spins the turbine rotors, electric current is generated.

Point Absorber
The point absorber is a floating structure that captures energy from the vertical motion of the waves. This up-and-down motion of the device drives generators that create an electric current.

Surge Converter
This style of device harnesses wave energy directly from the surging and swelling motion of waves. It uses the oscillation between a float, flap, or membrane and a fixed point. That movement creates a usable form of mechanical energy. Similar devices are also being developed that utilize pitching, heaving, and swaying motions.

Wave Attenuator
This device is long and multi-segmented and floats on the surface. The attenuator is anchored in place with a mooring line and positioned perpendicularly to incoming waves. Some attenuators tap only the heave (vertical motion); others tap both heave and surge. The device captures energy as the motion of the wave causes it to flex where the segments connect. This movement then drives hydraulic pumps or generators.

B. Tidal

Tidal energy is created through the use of tidal energy generators. In areas where tidal movements are high, large underwater turbines are placed to capture the kinetic motion of ocean tides to produce electricity. Tidal energy technologies include barrages or dams, tidal fences, and tidal turbines.

Barrages or Dams
A barrage or dam is typically used to convert tidal energy into electricity by forcing water through turbines, which activate a generator. Gates and turbines are installed along the dam. When the tides produce an adequate difference in the level of water on opposite sides of the dam, the gates are opened. The water then flows through the turbines. The turbines turn an electric generator to produce electricity.

Tidal Fences
Tidal fences look like giant turnstiles. They can reach across channels between small islands or across straits between the mainland and an island. The turnstiles spin via tidal currents typical of coastal waters. Some of these currents run at 5–8 knots (5.6–9 miles per hour) and generate as much energy as winds of much higher velocity.

Tidal Turbines
Tidal turbines look like wind turbines. They are arrayed underwater in rows, as in some wind farms. The turbines function best where coastal currents run between 3.6 and 4.9 knots (4 and 5.5 mph). In currents of that speed, a 49.2-foot (15-meter) diameter tidal turbine can generate as much energy as a 197-foot (60-meter) diameter wind turbine. Ideal locations for tidal turbine farms are close to shore in water 65.5–98.5 feet (20–30 meters) deep.

C. Offshore

Offshore wind turbines are being used by a number of countries to harness the energy of strong, consistent winds that are found over the oceans. Offshore winds tend to blow harder and more uniformly than on land.

The engineering and design of offshore wind facilities depends on site-specific conditions, particularly water depth, geology of the seabed, and wave loading. Today’s offshore turbines have technical modifications and substantial system upgrades for adaptation to the marine environment. These modifications include items such as: strengthening the tower to cope with loading forces from waves or ice flows, pressurizing nacelles to keep corrosive sea spray from critical electrical components, and adding brightly colored access platforms for navigation safety and maintenance access.
