Seabased wave energy plants are complete systems consisting of a number of Wave Energy Converters, WECs, each comprising a point absorbing buoy on the ocean surface directly connected to a linear generator on the ocean floor, and an electrical system which provides electrical conversion and transmission of the generated energy to the grid connection point on shore.
The functionality of the total system has been verified through the grid connection of the Sotenäs Wave Power Plant and subsequent generation of power to the Nordic Electricity Grid.
Locating the linear generators on the seabed protects them from the extreme conditions that may occur on the sea surface and helps minimizing the maintenance required. Combined with a mechanically simple (very few moving parts) and robust generator technology, an efficient energy conversion system can be achieved.
The Seabased solution is highly modular and smaller or larger wave power plants can easily be built up from the same standard building blocks. This design philosophy also facilitates a stepwise build-up or expansion, increasing flexibility and reducing investment risk.
Manufacturing is carried out at the Seabased factory in Lysekil, Sweden, a deep integration facility with the capability of carrying out in-house most of what is required for the delivery of a complete wave energy plant. With complete control of all operations such as cutting, welding, machining, milling, sand blasting, painting, etc as well as final assembly and testing, quality as well as cost efficiency are ensured. Some of the operations are robotized.
Seabased has a very comprehensive patent portfolio, comprising around 20 patent families and with each patent filed in multiple jurisdictions focusing on Sweden and Western Europe, USA, Canada, Brazil, China, India, Japan, Indonesia, Australia and New Zealand.
According to sources such as World Ocean Review, the global technical potential of wave energy is huge and estimated at 10,000 to 15,000 TWh per year, corresponding to around 1,000 billion USD of electricity sales per year.
Today, a Seabased wave energy plant can be supplied at a cost which is well competitive with renewable energy sources such as wind or solar PV as well as with diesel power generation.
Within a few years the continuing improvements in our technology and operations, investments in more efficient production, etc and the benefits to be derived from economy of scale, will enable us to offer competitively to a substantially broader market.
Since the beginning the focus has been on an environmentally friendly design. All materials and components are well known and compatible with the environment. The use of chemicals and oils has been minimized. The visual impact from a Seabased wave energy plant is limited to the view of the buoys.
