CORPOWER’S WAVE ENERGY CONCEPT

–

–

Our Wave Energy Converters are point absorber type, with a heaving buoy on the surface absorbing energy from ocean waves. The buoy is connected to the seabed using a tensioned mooring system. Novel phase control technology makes the compact devices oscillate in resonance with the incoming waves, strongly amplifying the motion and power capture. The system has improved survivability in storms, thanks to its inherent transparency to incoming wave energy in long storm waves.

The concept offers five times more energy per ton of device compared to previously known wave technologies. The high structural efficiency allows for a large amount of energy to be harvested using a relatively small and low-cost device, reducing the equipment (CAPEX) cost per MW capacity. The compact and lightweight WECs are also easy to install and maintain using low-cost vessels, bringing down operational (OPEX) costs. All together this provides competitive cost-of-energy.

Generators and power electronics are standard components known from the wind industry, enabling well known grid connection architecture. Our product concept is optimized for 10MW clusters, where the electricity is collected from an array of WECs into a collection hub. Each 10MW hub delivers grid quality electricity with standard 33/66kV electrical connection commonly used in offshore wind, with a single control and data acquisition interface over fibre and radio-link to the hub. Each WEC operate autonomously by a programmable logic controller located inside the device.

–

–

The wave farm concept is based on combining WEC clusters in arrays, connecting to a common grid export cable. The electrical architecture is chosen to allow export cables and substations to be shared with offshore wind, for projects aiming to take advantage of the complementary production profile between the wave and wind resource to deliver more continuous output from the array.

The array concept with many small units allows for mass production to drive down the cost per unit. An effective maintenance scheme is offered based on either replacing entire units or performing simple maintenance work offshore, improving farm uptime and providing overall reduction of O&M cost. The replacement scheme is enabled by the small physical size and limited cost per system, allowing simple handling and reasonable investment in spare units.

–

–

DESIGN PHILOSOPHY

–

Inspired by the pumping principle of the human heart, CorPower uses stored pressure to generate energy from waves in two directions. The human heart uses stored hydraulic pressure to provide force for the return stroke, thereby only requiring the muscles of the heart to pump in one direction. In a similar way, CorPower WEC uses a pre-tension system to pull the buoy downwards.

It mimics the energy storage aspect of the human heart whereby the upward force of a wave swell pushes the buoy upwards while the stored pressure provides the restoring force drives the buoy downwards. This results in an equal energy production in both directions, and a lightweight system that is naturally transparent (detuned) unless actively controlled to match the wave climate.

The CorPower WEC converts energy from waves into electricity through the rise and fall as well as the back and forth motion of waves. A composite buoy, interacting with this wave motion, drives a Power Take Off (drive train located inside the buoy) that converts the mechanical energy into electricity.  The light composite buoy is connected to the seabed through a power conversion module and a tension leg mooring system. In a conventional point absorber, the buoy follows the motion of the waves. The CorPower WEC on the other hand uses control technology to better leverage the motion of the waves by giving the oscillating motion optimal timing with each wave.

Storm Survivability: Reliable and efficient damping of wave energy devices is critical for robust operation in adverse weather conditions. Innovative machine elements will be demonstrated that in all operational conditions, including operation with faults, can provide safety and control of the machine.  This effort aims at eliminating the risk of end-stop impacts, which has been a significant cause for failure in previous wave devices and can be a driver of large and costly structures.

Fluctuating power input from ocean waves: Solutions to smoothen power variability by innovative load shedding will be demonstrated aiming to improve the overall efficiency and economics of direct drive trains.

WaveBoost objectives:

This project’s main objective was to improve the reliability and performance of PTOs by developing and validating a revolutionary braking module with advanced control that can be coupled to different types of WECs. The WaveBoost module incorporates safety logic and energy redistribution functions beyond that of previous PTOs.

The specific project objectives and outcomes are:

• Increase reliability and survivability of WECs;
• Increase performance and reduce cost of WECs;

Bombora’s core business is the supply of the key mWave^TM components, the cell modules and Power Take Off unit. Individual project requirements will determine what additional products and services Bombora would supply. The project delivery package could be a combination of any of or all of the following: product, project development services, engineering consulting, operations and maintenance management services.

Bombora can deliver wave energy as a true alternative to complement today’s renewable energy mix.

–

–

Technical overview

Bombora has developed a patented membrane-style wave energy converter, mWave™. mWave™ is unique among wave energy converters as it simultaneously addresses the cost of energy and ocean wave survivability challenges. This new approach proffers a new era for wave energy.

–

The Cell Module

mWave™ features a series of air-inflated rubber membrane covered concave cells mounted to a structure below the ocean’s surface creating an air-filled volume. To maximise energy capture, the structure is arranged at an angle to the incoming waves. As waves pass overhead, air is pushed out of each cell through a series of valves into a one-way air-duct . The cells are refilled once the wave has passed. The flexible membrane is made from industrial grade rubber. The longstanding use of similar materials in a range of marine applications has demonstrated the material’s reliability and longevity.

mWave™ has no external parts, other than the flexible rubber membranes. Our robust rubber cell membrane extracts power simply without complex mechanisms greatly reducing maintenance requirements. Our replaceable modular design streamlines maintenance, minimising downtime and maximising power output.

mWave™’s cell modules have the unique ability to shut down in extreme storm events. Limiting the loads reduces capital costs and improves the all important cost of electricity.

–

The Power Take-off
(PTO Turbine and Generator Module)

The air flow in the duct drives an unidirectional flow turbine which in turns drives a variable-speed generator. This type of turbine and generator are off-the shelf technology, even if adapted for the mWave™ operating envelope.

Electricity from the generator is transferred to the shore via a sub-sea cable. Following a process of power conditioning, the electricity is delivered into the local grid.

All operations and maintenance are achievable using existing service vessels used in both fixed bottom wind and offshore oil and gas industries.

mWave™ can be deployed on different platforms to suit a nearshore or offshore ocean environment. Find out more about Bombora’s Fixed mWave™ , Floating mWave™ and Integrated mWave™ platforms

Wave Swell is a developer of world leading proprietary technology which works to convert the energy in ocean waves into clean and emissions free electricity

–

Uniwave^®

The Wave Swell Energy (WSE) technology is based on the well-established concept of the oscillating water column (OWC).

–

–

The OWC is an artificial blowhole consisting of a chamber that is open underneath the waterline. As waves pass the OWC, the water rises and falls inside, forcing the air to pass by a turbine at the top of the chamber. This turbine generates electricity.

Previous OWC technologies have all been bidirectional. The WSE technology, however, operates unidirectionally. This results in the WSE turbine being simpler, more robust and reliable, and exhibiting a higher energy conversion efficiency. The only moving parts in the technology are the turbine and bespoke valves, all of which are well above the water line. There are no moving parts in or below the water.

–

A world first project

WSE has deployed its 200kW wave energy project on King Island, Tasmania, adjacent to the harbour at the township of Grassy.

–

–

The unit was installed at Grassy, King Island, on January 10, 2021. It has since been commissioned, exporting its first power into the King Island grid on June 18, 2021. These are significant events for WSE’s shareholders and stakeholders.

WSE has worked with Hydro Tasmania, the island’s energy and network provider, to connect the unit to the local grid, and is now delivering energy from the project into the existing network. Hydro Tasmania will separately monitor the energy produced by the unit to ensure it meets the requirements of the King Island grid.

The wave energy produced will complement Hydro Tasmania’s existing hybrid grid, further diversifying the renewable sources and reducing diesel consumption on King Island.

The UniWave200 is now contributing to the mix of energy resources used to power the homes and industries of King Island.

–

–

–

What is the King Island Project Expected to Achieve?

The primary purpose of Wave Swell Energy’s (WSE) UniWave200 King Island project is to validate the models entailed in the various stages of the technology’s power conversion process.

–

–

This will be achieved in a comprehensive “wave to wire” fashion via the following modules:

• wave to pneumatic power – by validating the Australian Maritime College (AMC) physical scale model testing results in a full-scale ocean environment
• pneumatic to mechanical power – by validating the turbine efficiency model via a full-scale WSE turbine operating in a UniWave200 device in the real ocean
• mechanical to grid – by validating the electrical model via a full-scale electrical system installed in a UniWave device operating in the real ocean

These results will provide WSE with a baseline and the tools and inputs from which to develop the technology further as part of Project Bluefire, the company’s planned technology enhancement program.

The AMC model tests, conducted at the institution’s test tank facilities in Launceston, provide a detailed matrix of pneumatic power¹ production across a range of different combinations of model scale wave height and period². The King Island unit is expected to encounter this same range of wave conditions at full scale at the Grassy site.

A direct comparison of the King Island unit’s pneumatic power with the corresponding results of the AMC model tests will allow the confirmation of the UniWave200’s pneumatic power performance matrix³.

The King Island project is also designed to confirm the performance and conversion efficiency of the WSE turbine⁴. This bespoke turbine has been designed by a leading expert in the field of turbine design, based in the US.

Additionally, the King Island project will provide data that enables a refinement of the WSE electrical control system. The purpose of this system is to efficiently convert the mechanical energy of the turbine shaft into electricity, minimising energy wastage, and maximising output. This electrical process incorporates a short-term storage facility, utilising state-of-the-art ultra-capacitors, to provide a smoother delivery of electrical energy to the grid.

When the pneumatic power, turbine conversion efficiency, and electrical conversion efficiency matrices are combined with the frequency of occurrence matrix⁵ for a given site, an accurate estimate of the unit’s power production can then be calculated for that site. In this way, the results from the King Island project will make it possible to accurately predict the total conversion efficiency⁶ and power output of the WSE technology at any site in the world for which comprehensive wave data⁷ is available.

The validation and results from these three stages of the process, whereby energy from the waves is converted into electricity, will be the cornerstone of the inputs into Project Bluefire. The outcome of Project Bluefire is expected to be a more efficient and lower cost technology that is more widely applicable in terms of depth and geography.

Finally, the King Island project will be a tangible demonstration of the ability of the WSE unidirectional OWC technology^8,9 to produce useable electrical energy capable of being incorporated into an island grid. It will also provide invaluable information and experience related to the unit’s day-to-day and long-term operation and maintenance.

King Island was chosen as a project site for two primary reasons – the wave climate and Hydro Tasmania. The wave climate in the region is amongst the best in the world.  And, Hydro Tasmania, being a world leader in the integration of renewables into island grids, provides the project with a virtually unparalleled level of relevant expertise. This will prove significant in demonstrating the technology’s value to remote island grids.

Grassy, on the east coast of King Island, was chosen as the specific project site for additional reasons. As the main commercial harbour for the island, the general site already has the necessary electrical and other infrastructure required by the WSE project. And, being on the east coast of the island, the wave conditions that will be encountered are expected to cover the full range, from small to large, needed to validate the AMC model tests. Given this project involves a demonstration unit, there is as much to be learned from the operation and maintenance of the unit as there is from the production of power. The Grassy location provides the ideal conditions required for regular and easy access for operating the unit, as well as delivering the range of wave conditions necessary to fully test the device.

Importantly, the King Island project is not aimed at maximising the power production of the unit. Doing so would require a more energetic wave location, such as the west coast of the King Island. Future projects, incorporating the improvements from Project Bluefire, will be located in more energetic wave regimes to maximise energy production.

Glossary of Terms

1.  Pneumatic Power: Power measured at the pneumatic stage of the conversion chain given as the product of the volume flow rate (m^3/s) with the differential pressure (Pa) between the OWC chamber and atmosphere.
2. Wave Height and Period: Wave height is the vertical distance between the wave crest and trough. Wave period is the time between two wave crests.
3. Pneumatic Power Performance Matrix: A two-dimensional graphical representation of the pneumatic power (pressurised air flow) corresponding to the sea state (a combination of a specific wave height and period).The matrix normally consists of height on the vertical axis and period on the horizontal axis.
4. Turbine Conversion Efficiency: The proportion of pneumatic power the rotating turbine converts to mechanical power.
5. Frequency of Occurrence Matrix: For a given location, the frequency (how often) each sea state occurs is known as the Frequency of Occurrence Matrix.
6. Total Conversion Efficiency: The proportion of wave power that is converted into electrical power across all stages of the energy conversion process.
7. Wave Data: The sea state collected at a given location that allows for the Frequency of Occurrence Matrix to be populated (filled in).
8. OWC (Oscillating Water Column): An oscillating water column consists of a large chamber that sits partially below the water and partially above, with a ‘mouth’ or entry duct open below the water line, and a small aperture open above. The chamber acts like an artificial blowhole, with energy from the waves entering and leaving the mouth, and energy in the air flow entering and leaving via the aperture, in which is housed a turbine.
9. Unidirectional OWC: A variant of OWC technology that is unique to Wave Swell Energy and protected by an international patent. The technology enables simple rectification of air flow so that a more efficient and robust unidirectional air turbine can be used for pneumatic to mechanical energy conversion. Temporary energy storage in the water column is the key to why this concept works and explains why the energy is not being lost by venting the air chamber.
